2 Preparations21 Preparing the pipe and valveLocate the exact point for the joint on the main pipe line and prepare the main pipe for welding of the valve Check the place of the joint on the main pipe (if the main pipe is a weld seam tube avoid welding the hot tapping valve on the weld seam)

Prepare the weld end of the hot tapping valve to match the radius (ldquoRrdquo) of the main pipe and taper the edges as required for the best welding result (see figure 1)

The weld seam has to comply with the local requirements for size and strength A support collar is to be used when necessary

NOTE The threaded end of the valve may be prepared for welding or shortened only after drilling through the main pipe

Figure 1

8 9wwwvexvecom

22 Preparing the hot tapping drillSelect the hole saw that corresponds to the valversquos DN size Also select a drill chuck and adapter of corresponding size from the case First install the adapter to the tool and after that install the drill chuck assembly (drill chuck + pilot drill bit + hole saw) on the shaft of the tool

Check that the edge of Frame I is aligned with the groove on Frame II (see figure 4 the groove is on the threaded area of Frame II) This setup corresponds to the maximum feeding distance This position must not be exceeded under any circumstances when the tool is pressurized

Make sure that the valve is fully OPEN Attach the complete tool assembly to the threads on the valve and test that the hole saw can freely slide through the ball in the valve

After welding the tightness of the seam can be tested eg by pressure testing the joint with compressed air through the hot tapping toolrsquos draining valve

Figure 2 Figure 3

Figure 4

The valve may be welded to the main pipe at any angle between 0deg and 360deg (see figure 2) but it must be at a 90deg angle to the longitudinal axis of the main pipe (see figure 3)

8 9wwwvexvecom wwwvexvecom

Attach the draining valve with hose to Frame II and close the draining valve

Before drilling through the main pipe test that the valve can be closed release the shaftrsquos locking mechanism by pulling the spring loaded part 400012 (see page 6) and slide out the shaft until it mechanically stops at the outermost position Close and open the hot tapping valve to verify it is working properly

Select a locking position that corresponds to the size of the hot tapping valve and lock the shaft to the selected position (three alternatives mdashgt see page 6)

3 Hot tapping31 Checklist for power drill the rotation direction must be clockwise

the percussion function must not be on under any circumstances

select rotation speed area 1 or 2 (see figure 5)

set RPM scale A - F (see figure 6)

Figure 5 Figure 6

10 11wwwvexvecom

32 Drilling

When starting the drilling ie when drilling the pilot hole use high RPM (460 RPM) area 2 and scale F Feed the drill through steadily and smoothly During drilling it is recommended to keep the draining valve open to remove the cuttings

Stop after only drilling through with the pilot drill bit Adjust the speed of rotation area (1 or 2) and scale (A-F) for the actual hole cutting and close the draining valve

Feed the hole saw through steadily and smoothly During cutting you may keep the draining valve open close it after finishing

Release the shaft locking mechanism and slide the shaft to its outermost position (due to pressure in the valve the shaft slides out automatically) then close the hot tapping valve Open the draining valve to release the pressure from the hot tapping valve

WARNING Before releasing the shaftrsquos locking mechanism move your head away from shaftrsquos end to avoid impact The shaft will slide out rapidly under water pressure

NOTE Before removing the drilling tool from the hot tapping valve make sure that the valve is fully closed check the markings at the stem The tightness of the hot tapping valve must be verified by using the draining valve no water must flow through the draining valve after the hot tapping valve is closed

After the drilling is finished it is important to clean the hot tapping tool from any metal chips and other impurities that have come in the drilling process

Disassemble the hot tapping drill first remove the draining valve and after that remove the tool (incl adapter) from the hot tapping valve Then disassemble the drill in the reverse order as you had assembled it

Closing the stem by welding If required the stem can be permanently closed by welding Remove the PTFE sealing underneath the cap before welding

33 Technical criteria for power drillWe recommend the following power drills

Milwaukee PD2E 24RS

AEG SB2E 1200 RST

If you use another drill make sure that it fulfills the following criteria

input power min 1000 W speed of rotation areas Area 1 0 - 1000 RPM Area 2 0 - 3000 RPM required speed adjustments are available for differently-sized hole saws

the drillrsquos neck diameter must be 43 mm

NOTE If you select another brand or model please check with the manufacturer that it fulfills above mentioned criteria

32 Drilling

When starting the drilling ie when drilling the pilot hole use high RPM (460 RPM) area 2 and scale F Feed the drill through steadily and smoothly During drilling it is recommended to keep the draining valve open to remove the cuttings

Stop after only drilling through with the pilot drill bit Adjust the speed of rotation area (1 or 2) and scale (A-F) for the actual hole cutting and close the draining valve

Feed the hole saw through steadily and smoothly During cutting you may keep the draining valve open close it after finishing

Release the shaft locking mechanism and slide the shaft to its outermost position (due to pressure in the valve the shaft slides out automatically) then close the hot tapping valve Open the draining valve to release the pressure from the hot tapping valve

WARNING Before releasing the shaftrsquos locking mechanism move your head away from shaftrsquos end to avoid impact The shaft will slide out rapidly under water pressure

NOTE Before removing the drilling tool from the hot tapping valve make sure that the valve is fully closed check the markings at the stem The tightness of the hot tapping valve must be verified by using the draining valve no water must flow through the draining valve after the hot tapping valve is closed

After the drilling is finished it is important to clean the hot tapping tool from any metal chips and other impurities that have come in the drilling process

Disassemble the hot tapping drill first remove the draining valve and after that remove the tool (incl adapter) from the hot tapping valve Then disassemble the drill in the reverse order as you had assembled it

Closing the stem by welding If required the stem can be permanently closed by welding Remove the PTFE sealing underneath the cap before welding

2 Preparations21 Preparing the pipe and valveLocate the exact point for the joint on the main pipe line and prepare the main pipe for welding of the valve Check the place of the joint on the main pipe (if the main pipe is a weld seam tube avoid welding the hot tapping valve on the weld seam)

Prepare the weld end of the hot tapping valve to match the radius (ldquoRrdquo) of the main pipe and taper the edges as required for the best welding result (see figure 1)

The weld seam has to comply with the local requirements for size and strength A support collar is to be used when necessary

NOTE The threaded end of the valve may be prepared for welding or shortened only after drilling through the main pipe

Figure 1

22 Preparing the hot tapping drillSelect the hole saw that corresponds to the valversquos DN size Also select a drill chuck and adapter of corresponding size from the case First install the adapter to the tool and after that install the drill chuck assembly (drill chuck + pilot drill bit + hole saw) on the shaft of the tool

Check that the edge of Frame I is aligned with the groove on Frame II (see figure 4 the groove is on the threaded area of Frame II) This setup corresponds to the maximum feeding distance This position must not be exceeded under any circumstances when the tool is pressurized

Make sure that the valve is fully OPEN Attach the complete tool assembly to the threads on the valve and test that the hole saw can freely slide through the ball in the valve

After welding the tightness of the seam can be tested eg by pressure testing the joint with compressed air through the hot tapping toolrsquos draining valve

Figure 2 Figure 3

Figure 4

The valve may be welded to the main pipe at any angle between 0deg and 360deg (see figure 2) but it must be at a 90deg angle to the longitudinal axis of the main pipe (see figure 3)

2 Preparations21 Preparing the pipe and valveLocate the exact point for the joint on the main pipe line and prepare the main pipe for welding of the valve Check the place of the joint on the main pipe (if the main pipe is a weld seam tube avoid welding the hot tapping valve on the weld seam)

Prepare the weld end of the hot tapping valve to match the radius (ldquoRrdquo) of the main pipe and taper the edges as required for the best welding result (see figure 1)

The weld seam has to comply with the local requirements for size and strength A support collar is to be used when necessary

NOTE The threaded end of the valve may be prepared for welding or shortened only after drilling through the main pipe

Figure 1

8 9wwwvexvecom

22 Preparing the hot tapping drillSelect the hole saw that corresponds to the valversquos DN size Also select a drill chuck and adapter of corresponding size from the case First install the adapter to the tool and after that install the drill chuck assembly (drill chuck + pilot drill bit + hole saw) on the shaft of the tool

Check that the edge of Frame I is aligned with the groove on Frame II (see figure 4 the groove is on the threaded area of Frame II) This setup corresponds to the maximum feeding distance This position must not be exceeded under any circumstances when the tool is pressurized

Make sure that the valve is fully OPEN Attach the complete tool assembly to the threads on the valve and test that the hole saw can freely slide through the ball in the valve

After welding the tightness of the seam can be tested eg by pressure testing the joint with compressed air through the hot tapping toolrsquos draining valve

Figure 2 Figure 3

Figure 4

The valve may be welded to the main pipe at any angle between 0deg and 360deg (see figure 2) but it must be at a 90deg angle to the longitudinal axis of the main pipe (see figure 3)

8 9wwwvexvecom wwwvexvecom

Attach the draining valve with hose to Frame II and close the draining valve

Before drilling through the main pipe test that the valve can be closed release the shaftrsquos locking mechanism by pulling the spring loaded part 400012 (see page 6) and slide out the shaft until it mechanically stops at the outermost position Close and open the hot tapping valve to verify it is working properly

Select a locking position that corresponds to the size of the hot tapping valve and lock the shaft to the selected position (three alternatives mdashgt see page 6)

3 Hot tapping31 Checklist for power drill the rotation direction must be clockwise

the percussion function must not be on under any circumstances

select rotation speed area 1 or 2 (see figure 5)

set RPM scale A - F (see figure 6)

Figure 5 Figure 6

10 11wwwvexvecom

32 Drilling

When starting the drilling ie when drilling the pilot hole use high RPM (460 RPM) area 2 and scale F Feed the drill through steadily and smoothly During drilling it is recommended to keep the draining valve open to remove the cuttings

Stop after only drilling through with the pilot drill bit Adjust the speed of rotation area (1 or 2) and scale (A-F) for the actual hole cutting and close the draining valve

Feed the hole saw through steadily and smoothly During cutting you may keep the draining valve open close it after finishing

Release the shaft locking mechanism and slide the shaft to its outermost position (due to pressure in the valve the shaft slides out automatically) then close the hot tapping valve Open the draining valve to release the pressure from the hot tapping valve

WARNING Before releasing the shaftrsquos locking mechanism move your head away from shaftrsquos end to avoid impact The shaft will slide out rapidly under water pressure

NOTE Before removing the drilling tool from the hot tapping valve make sure that the valve is fully closed check the markings at the stem The tightness of the hot tapping valve must be verified by using the draining valve no water must flow through the draining valve after the hot tapping valve is closed

After the drilling is finished it is important to clean the hot tapping tool from any metal chips and other impurities that have come in the drilling process

Disassemble the hot tapping drill first remove the draining valve and after that remove the tool (incl adapter) from the hot tapping valve Then disassemble the drill in the reverse order as you had assembled it

Closing the stem by welding If required the stem can be permanently closed by welding Remove the PTFE sealing underneath the cap before welding

33 Technical criteria for power drillWe recommend the following power drills

Milwaukee PD2E 24RS

AEG SB2E 1200 RST

If you use another drill make sure that it fulfills the following criteria

input power min 1000 W speed of rotation areas Area 1 0 - 1000 RPM Area 2 0 - 3000 RPM required speed adjustments are available for differently-sized hole saws

the drillrsquos neck diameter must be 43 mm

NOTE If you select another brand or model please check with the manufacturer that it fulfills above mentioned criteria

32 Drilling

When starting the drilling ie when drilling the pilot hole use high RPM (460 RPM) area 2 and scale F Feed the drill through steadily and smoothly During drilling it is recommended to keep the draining valve open to remove the cuttings

Stop after only drilling through with the pilot drill bit Adjust the speed of rotation area (1 or 2) and scale (A-F) for the actual hole cutting and close the draining valve

Feed the hole saw through steadily and smoothly During cutting you may keep the draining valve open close it after finishing

Release the shaft locking mechanism and slide the shaft to its outermost position (due to pressure in the valve the shaft slides out automatically) then close the hot tapping valve Open the draining valve to release the pressure from the hot tapping valve

WARNING Before releasing the shaftrsquos locking mechanism move your head away from shaftrsquos end to avoid impact The shaft will slide out rapidly under water pressure

NOTE Before removing the drilling tool from the hot tapping valve make sure that the valve is fully closed check the markings at the stem The tightness of the hot tapping valve must be verified by using the draining valve no water must flow through the draining valve after the hot tapping valve is closed

After the drilling is finished it is important to clean the hot tapping tool from any metal chips and other impurities that have come in the drilling process

Disassemble the hot tapping drill first remove the draining valve and after that remove the tool (incl adapter) from the hot tapping valve Then disassemble the drill in the reverse order as you had assembled it

Closing the stem by welding If required the stem can be permanently closed by welding Remove the PTFE sealing underneath the cap before welding

2 Preparations21 Preparing the pipe and valveLocate the exact point for the joint on the main pipe line and prepare the main pipe for welding of the valve Check the place of the joint on the main pipe (if the main pipe is a weld seam tube avoid welding the hot tapping valve on the weld seam)

Prepare the weld end of the hot tapping valve to match the radius (ldquoRrdquo) of the main pipe and taper the edges as required for the best welding result (see figure 1)

The weld seam has to comply with the local requirements for size and strength A support collar is to be used when necessary

NOTE The threaded end of the valve may be prepared for welding or shortened only after drilling through the main pipe

Figure 1

22 Preparing the hot tapping drillSelect the hole saw that corresponds to the valversquos DN size Also select a drill chuck and adapter of corresponding size from the case First install the adapter to the tool and after that install the drill chuck assembly (drill chuck + pilot drill bit + hole saw) on the shaft of the tool

Check that the edge of Frame I is aligned with the groove on Frame II (see figure 4 the groove is on the threaded area of Frame II) This setup corresponds to the maximum feeding distance This position must not be exceeded under any circumstances when the tool is pressurized

Make sure that the valve is fully OPEN Attach the complete tool assembly to the threads on the valve and test that the hole saw can freely slide through the ball in the valve

After welding the tightness of the seam can be tested eg by pressure testing the joint with compressed air through the hot tapping toolrsquos draining valve

Figure 2 Figure 3

Figure 4

The valve may be welded to the main pipe at any angle between 0deg and 360deg (see figure 2) but it must be at a 90deg angle to the longitudinal axis of the main pipe (see figure 3)

Attach the draining valve with hose to Frame II and close the draining valve

Before drilling through the main pipe test that the valve can be closed release the shaftrsquos locking mechanism by pulling the spring loaded part 400012 (see page 6) and slide out the shaft until it mechanically stops at the outermost position Close and open the hot tapping valve to verify it is working properly

Select a locking position that corresponds to the size of the hot tapping valve and lock the shaft to the selected position (three alternatives mdashgt see page 6)

5 Hot tapping through DN 150 full bore valve (or DN 200 reduced bore)

Naval standard hot tapping tool can be used also for DN 150 full bore valve

Following matters must be observed

New - +200mm - Longer shaft is needed

Hole saw 146 mm and center drill 8 mm must be used

Instead of standard adapter the tool and valves are assembled together with 2 pcs of PN 25 flanges sealing and boltsnuts The flange could be dismantled later

The stem of the valve is hexagon 32 mm

Part numbers are

- Long shaft (artnr 400210) and chuck (artnr 400240)

- Hole saw 146 mm (artnr 400072)

- Adapter for FB DB 150 (art nr 400066) and adapter for DN 200 with the flange (artnr 400067)

Procedure

1 Tapping center drill shall not be drilled with the highest speed but so that the drilling machine goes with 200rmin Position rdquo2rdquo - rolling plate rdquoArdquo

2 Hole saw speed - position ldquo1rdquo and rolling plate rdquoArdquo

3 Push down slowly

4 Push down and take up push down and take up

5 Cut off the connection flange with for example angle grinder or some cutting tool designed for metal Cut the pipe right below the flange as near the flange as possible

2 Preparations21 Preparing the pipe and valveLocate the exact point for the joint on the main pipe line and prepare the main pipe for welding of the valve Check the place of the joint on the main pipe (if the main pipe is a weld seam tube avoid welding the hot tapping valve on the weld seam)

Prepare the weld end of the hot tapping valve to match the radius (ldquoRrdquo) of the main pipe and taper the edges as required for the best welding result (see figure 1)

The weld seam has to comply with the local requirements for size and strength A support collar is to be used when necessary

NOTE The threaded end of the valve may be prepared for welding or shortened only after drilling through the main pipe

Figure 1

22 Preparing the hot tapping drillSelect the hole saw that corresponds to the valversquos DN size Also select a drill chuck and adapter of corresponding size from the case First install the adapter to the tool and after that install the drill chuck assembly (drill chuck + pilot drill bit + hole saw) on the shaft of the tool

Check that the edge of Frame I is aligned with the groove on Frame II (see figure 4 the groove is on the threaded area of Frame II) This setup corresponds to the maximum feeding distance This position must not be exceeded under any circumstances when the tool is pressurized

Make sure that the valve is fully OPEN Attach the complete tool assembly to the threads on the valve and test that the hole saw can freely slide through the ball in the valve

After welding the tightness of the seam can be tested eg by pressure testing the joint with compressed air through the hot tapping toolrsquos draining valve

Figure 2 Figure 3

Figure 4

The valve may be welded to the main pipe at any angle between 0deg and 360deg (see figure 2) but it must be at a 90deg angle to the longitudinal axis of the main pipe (see figure 3)

8 9wwwvexvecom wwwvexvecom

Attach the draining valve with hose to Frame II and close the draining valve

Before drilling through the main pipe test that the valve can be closed release the shaftrsquos locking mechanism by pulling the spring loaded part 400012 (see page 6) and slide out the shaft until it mechanically stops at the outermost position Close and open the hot tapping valve to verify it is working properly

Select a locking position that corresponds to the size of the hot tapping valve and lock the shaft to the selected position (three alternatives mdashgt see page 6)

3 Hot tapping31 Checklist for power drill the rotation direction must be clockwise

the percussion function must not be on under any circumstances

select rotation speed area 1 or 2 (see figure 5)

set RPM scale A - F (see figure 6)

Figure 5 Figure 6

10 11wwwvexvecom

32 Drilling

When starting the drilling ie when drilling the pilot hole use high RPM (460 RPM) area 2 and scale F Feed the drill through steadily and smoothly During drilling it is recommended to keep the draining valve open to remove the cuttings

Stop after only drilling through with the pilot drill bit Adjust the speed of rotation area (1 or 2) and scale (A-F) for the actual hole cutting and close the draining valve

Feed the hole saw through steadily and smoothly During cutting you may keep the draining valve open close it after finishing

Release the shaft locking mechanism and slide the shaft to its outermost position (due to pressure in the valve the shaft slides out automatically) then close the hot tapping valve Open the draining valve to release the pressure from the hot tapping valve

WARNING Before releasing the shaftrsquos locking mechanism move your head away from shaftrsquos end to avoid impact The shaft will slide out rapidly under water pressure

NOTE Before removing the drilling tool from the hot tapping valve make sure that the valve is fully closed check the markings at the stem The tightness of the hot tapping valve must be verified by using the draining valve no water must flow through the draining valve after the hot tapping valve is closed

After the drilling is finished it is important to clean the hot tapping tool from any metal chips and other impurities that have come in the drilling process

Disassemble the hot tapping drill first remove the draining valve and after that remove the tool (incl adapter) from the hot tapping valve Then disassemble the drill in the reverse order as you had assembled it

Closing the stem by welding If required the stem can be permanently closed by welding Remove the PTFE sealing underneath the cap before welding

33 Technical criteria for power drillWe recommend the following power drills

Milwaukee PD2E 24RS

AEG SB2E 1200 RST

If you use another drill make sure that it fulfills the following criteria

input power min 1000 W speed of rotation areas Area 1 0 - 1000 RPM Area 2 0 - 3000 RPM required speed adjustments are available for differently-sized hole saws

5 Hot tapping through DN 150 full bore valve (or DN 200 reduced bore)

Naval standard hot tapping tool can be used also for DN 150 full bore valve

Following matters must be observed

New - +200mm - Longer shaft is needed

Hole saw 146 mm and center drill 8 mm must be used

Instead of standard adapter the tool and valves are assembled together with 2 pcs of PN 25 flanges sealing and boltsnuts The flange could be dismantled later

The stem of the valve is hexagon 32 mm

Part numbers are

- Long shaft (artnr 400210) and chuck (artnr 400240)

- Hole saw 146 mm (artnr 400072)

- Adapter for FB DB 150 (art nr 400066) and adapter for DN 200 with the flange (artnr 400067)

Procedure

1 Tapping center drill shall not be drilled with the highest speed but so that the drilling machine goes with 200rmin Position rdquo2rdquo - rolling plate rdquoArdquo

2 Hole saw speed - position ldquo1rdquo and rolling plate rdquoArdquo

3 Push down slowly

4 Push down and take up push down and take up

5 Cut off the connection flange with for example angle grinder or some cutting tool designed for metal Cut the pipe right below the flange as near the flange as possible

Attach the draining valve with hose to Frame II and close the draining valve

Before drilling through the main pipe test that the valve can be closed release the shaftrsquos locking mechanism by pulling the spring loaded part 400012 (see page 6) and slide out the shaft until it mechanically stops at the outermost position Close and open the hot tapping valve to verify it is working properly

Select a locking position that corresponds to the size of the hot tapping valve and lock the shaft to the selected position (three alternatives mdashgt see page 6)

3 Hot tapping31 Checklist for power drill the rotation direction must be clockwise

the percussion function must not be on under any circumstances

select rotation speed area 1 or 2 (see figure 5)

set RPM scale A - F (see figure 6)

Figure 5 Figure 6

10 11wwwvexvecom

32 Drilling

When starting the drilling ie when drilling the pilot hole use high RPM (460 RPM) area 2 and scale F Feed the drill through steadily and smoothly During drilling it is recommended to keep the draining valve open to remove the cuttings

Stop after only drilling through with the pilot drill bit Adjust the speed of rotation area (1 or 2) and scale (A-F) for the actual hole cutting and close the draining valve

Feed the hole saw through steadily and smoothly During cutting you may keep the draining valve open close it after finishing

Release the shaft locking mechanism and slide the shaft to its outermost position (due to pressure in the valve the shaft slides out automatically) then close the hot tapping valve Open the draining valve to release the pressure from the hot tapping valve

WARNING Before releasing the shaftrsquos locking mechanism move your head away from shaftrsquos end to avoid impact The shaft will slide out rapidly under water pressure

NOTE Before removing the drilling tool from the hot tapping valve make sure that the valve is fully closed check the markings at the stem The tightness of the hot tapping valve must be verified by using the draining valve no water must flow through the draining valve after the hot tapping valve is closed

After the drilling is finished it is important to clean the hot tapping tool from any metal chips and other impurities that have come in the drilling process

Disassemble the hot tapping drill first remove the draining valve and after that remove the tool (incl adapter) from the hot tapping valve Then disassemble the drill in the reverse order as you had assembled it

Closing the stem by welding If required the stem can be permanently closed by welding Remove the PTFE sealing underneath the cap before welding

33 Technical criteria for power drillWe recommend the following power drills

Milwaukee PD2E 24RS

AEG SB2E 1200 RST

For pipe sizes DN ge100 with wall thickness ge 10 mm it is recommended to deduct 10 mm from the above rdquoArdquo dimensions to guarantee that the hole saw goes fully through the wall of the main pipe

The above rdquoArdquo dimensions are valid for Lenox holesaws When using a Sandvik hole saw an additional 10 mm must be deducted from these dimensions (A 38 mm diameter Sandvik hole saw is 10 mm lower than an equivalent Lenox one)
