    Hyram recommend that a pressure test is completed prior to making new connections. The following test pumps are available for hire and purchase.

    Important! This manual forms a part of the product to which it relates. It should be kept for the life of the product. Any amendments issued by Hy-Ram Engineering Co Ltd should be incorporated in the text. The manual should be passed to any subsequent holder or user of this product. Safety Information The Peart 150 Drilling Machine should only be used by trained and competent operators. As an operator, always ensure that you fully understand how the equipment functions and that you are fully aware of the dangers. Always wear the necessary protective clothing including adequate eye protection, hard hat, gloves, overalls, protective boots etc.

    Prior to commencing work, always ensure that the drill kit is complete and fully serviceable. If in doubt replace.

    Technical Descriptions Specification Nominal branch drill and tap size 50mm (2”) to 150mm (6”) as standard. Can be upgraded to drill 200mm (8”) Maximum working pressure 16 bar. Maximum working temperature 200 c. Boring bar travel 500mm. Power Supply Hydraulic or pneumatic motor suitable for connection to site services. Hand: by ratchet wrench supplied. Speeds Boring bar rotational speed free from load: 28rev/min with air or hydraulic motor. Boring bar automatic feed 0.15mm/rev for cutting. 2.31mm/rev for tapping (11 TP1). Description The Peart 150 underpressure drilling machine is designed to work on gas, water, oil or chemical pipelines up to the specified pressure and temperature limits. The machine is supplied in a wooden box complete with boring bar extension ratchet, wrench, spanner, hexagon wrench (allen key), machine adaptor gaskets and spare seal kits. Cutters, adaptors, motor kits etc, if required are supplied in separate boxes. Weight Basic machine 78kgs.

    Do’s and Don’ts Before attaching machine to valve fitting: Do:

    • Ensure that pressure and temperature of fluid in pipeline is within machine specification. • Ensure that cutters and pilot drills are sharp and in good condition. • Ensure that the valve gate is fully open. • Ensure that cutter will pass through valve. • Ensure that cutter and pilot drill are securely fastened to the boring bar. • Ensure that cutter can be fully retracted into flange adaptor. • Prior to installation of the drilling machine the operator shall check the traverse of the

    boring bar and the indicator scale. • Note the position of the boring bar and record from the indicator scale. • Using the handle provided activate the hand feed mechanism to traverse the boring bar

    through a distance between 300mm and 500mm. • Measure the physical distance travelled by the boring bar.

    • Record the indicator scale reading with the boring bar extended. • Check that the physical traverse of the boring bar and the displacement from the change

    in indicator readings correspond. • Any difference in between the indicator scale reading and the distance travelled is an

    indication that the indicator gearing mechanism is slipping and the indicator scale is providing inaccurate information.

    • Drilling MUST NOT be undertaken until the indicator scale is proven to provide accurate positional information.

    • The machine MUST Not be allowed to travel beyond the limited 500mm traverse. Don’t:

    • Fit blunt or damaged cutters. • Attempt to drill into pipelines containing fluids at higher pressure or temperature than the

    machine design allows ( see specification). Fluid must not be capable of corroding machine components. With machine attached to valve flange Do:

    • Check that screws on flange are tight. Use the correct number of screws. • Check that the valve can be closed with the cutter fully retracted. • Ensure that drilling machine is supported by suitable packers at gearcase end. • Ensure that the area around the machine is clear and allows easy access to the machine

    controls. • Ensure that machine can successfully complete the intended cut without reaching the end

    of the boring bar travel. • Ensure valve is fully open before starting to drill.


    • Allow machine to “hang” on valve flange when drilling horizontally. • Damage pilot drill point by feeding towards pipe to fast. During Drilling Do

    • Remove feed handle during automatic feed. Don’t

    • Leave the machine unattended whilst drilling. • Allow machine to continue to feed past end mark on indicator. • Feed by hand so fast that the machine stalls. • Put machine into reverse unless removing tap. • Reverse a cutter will damage the teeth.

    Stop drilling operation once pilot drill has broken through the main. Interrupt drilling operating between pilot drill breaking through and cup drill commencing its cut this could provide an overload condition on the cup drill causing severe damage.

    After Drilling Do

    • Ensure that boring bar is fully retracted before attempting to close valve. • Ensure that pressure in adaptor is release before loosening flange screws. Don’t

    • Attempt or close valve with boring bar extended. After removal from Valve Do

    • Clean machine and all separate parts and replace in boxes. • Clean, lightly oil and retract machine boring bar. • Leave automatic feed lever off. • Check cutters for damage and obtain replacements if necessary. Unpacking Check that all parts are to hand and in good condition. Cutters and pilot drills should be inspected for chipped or broken cutting edges. Replace any damaged cutters or drills. The detent on the pilot drill should be free to move and shown on signs of damage: faulty detent will result in the coupon being lost during drilling. Assembling machine, motor and cutters Assemble correct machine adaptor to the front flange of drilling machine using correct gasket. A plug or valve should be fitted into the tapped hole on the side of the adaptor flange. Advance boring bar by rotating feed handle anti-clockwise so that it protrudes beyond the adaptor flange. Check that cutter will pass through the open branch valve. Fit cutter and pilot drill to boring bar using the correct cap screw and ensure that the screw is tight. Withdraw cutter into adaptor. Using the correct number and type of flange screws, fit the machine to the valve. We strongly recommend that the branch connection and valve are checked at this stage to ensure that:

    • The valve opens and closes satisfactorily. • The connection is pressure tight.

    Check the valve is open, fit motor to machine drive spindle.

    IMPORTANT SAFETY NOTICE: Hydraulic and pneumatic motors should be fitted with the correct adaptor sleeves and torque tubes (see drawing). Failure to do so will cause damage to the machine and injury to the operator. Drilling: Disengage automatic feed and wind cutter forward until it touches pipe wall. Note position of indicator on scale to determine break through point. Mark this point on the scale. Start machine and start automatic feed. Machine will be heard to cut. The machine should never be allowed to drill unattended and a close watch should be kept on its progress. In case of trouble, stop the machine and refer to fault finding chart. After machine has reached break through point and cutting has ceased stop automatic feed. Withdraw cutter into adaptor flange with the crank handle: do not attempt to exceed travel of indicator. Close Valve, Bleed excess pressure from adaptor flange by removing plug on side of adaptor Remove machine (reverse of assembly). Tapping The Peart 150 underpressure drilling machine is capable of tapping steel, cast grey and ductile iron with threads of 11 threads per inch. Note: Always ensure that there is end float on the tap. The tap should be capable of being moved along the adaptor approximately 0.5mm with the pilot drill tightened into its socket. If there is no end float, see the fault chart. The procedure is similar to drilling (including checking that the tap will pass through the valve) until the machine is wound forward so that the point of the pilot drill touches the pipe wall. With the pilot drill touching the pipe wall, fit the tapping indicator (UP3641) to the machine scale with the set notch in line with the red indicator. Start machine until the indicator is adjacent to the start tap notch.
