POWER CONVERSIONS
= 550 foot lb force/sec1 Horsepower = 33 000 foot lb force/min(British) = 745.7 watts = 1.013 87 metric horsepower1 kilowatt = 1.34 horsepower (British)
To calculate the mass of a tube/m (per meter)
Subtract the square of the inside from the square of the outside diameter (in mm) and multiply the result by:0.006 for steel0.005 for ironThis gives mass in kg/mAlternative method (approximate).Add the wall thickness (t) in mm to the bore (d) and multiply this sum by the wall thickness (t) and by 0.024 to give the mass of the steel tube in kilograms per metre.i.e. Mass = 0.024 (d+t)t in kg/m.

N.B.: These pipes can be used for higher pressures than those above, or for special working conditions with suitable types of joint.The effi ciency of taper/parallel screwed joints is highly dependent on the degree of care taken in assembly and jointing compound used.Light pipes are not recommended for steam, air or gas services.Reference to steam services applies to saturated steam only.

SETTING GAPThe setting gap is the distance between the pipe ends after the coupling has been assembled
SLEEVE WIDTH PIPE OUTSIDE DIAMETER SETTING GAP mm mm mm
83 <60 14.5 102 >60 <328 19.0 178 >60 <1829 38.0
Where locating plugs are used. the setting gap should be increased by 9.5mm for sizes up to 324mm OD and 12.5mm for sizes above 324mm OD to avoid contact with the plugs.
ANGULARITYEach Straight Coupling will allow for a setting angularity as follows:
COUPLING SIZE ANGLE INCLINATION
Up to 457 mm OD ±6° 1 in 10Over 457 mm tot 610 mm OD ±5° 1 in 12Over 610 mm tot 762 mm OD ±4° 1 in 15Over 762 mm to 1 219mm OD ±3° 1 in 20
The above schedule should only be used when the pipes will not move in service. Where movement of the pipes may occur subsequent to laying, we recommend working to half these fi gures to allow for in-service fl exibility.
Pipe ends should be smooth, with no seams, score marks, dents or ovality beyond those detailed in BS534-1990 Section 15.

ENERGY DISSIPATOR
The Energy Dissipator is a proprietary unit for reducing fl ow or energy owing to head in a pipeline system.
Although it was designed primarily for solids, owing to its wear resistant design and materials selections, it is equally suitable for water and other liquid applications.
Each unit is designed specifi cally for the end users duty by professional engineers.
Range of size and pressure/pressure drop requirements to be specifi ed by client.

“HI-PRESSTM” COMPACT FLANGESAn economical design with considerable weight saving compared with standard ANSI fl anges and at the same time maintaining a high integrity joint.
SEAL OPTION 1The “hi-pressTM” self energizing seal. This well established and proven seal provides the ultimate in reliability under high pressure and with the steel backing ring ensures alignment of fl anges and assists in the bolting procedure.
Substantial size and weight saving when compared with standard API and ANSI fl anges using compressible and/or ring type joints of the same pressure rating.
SEAL OPTION 2The “hi-pressTM” fl at seal requires no grooves in the fl anges and is replaceable without having to remove pipes.The disadvantage is that the fl at seal does not align the two fl anges and the fl ange faces do not butt up to each other which could cause turbulence at the joint (gasket thickness 5mm).

ANSI FLANGE (ANSI B16.5) – MATERIALMaterial Specifi cations for ANSI Flanges (ASTM Standard)
Notes:1. Manganese may be increased to 1.35% max. provided the car bon is
reduced 0.01% for each increase in manganese over the limit shown in the table.
2. For each reduction of 0.01% below the specifi ed carbon max i mum (0.35%), an increase of 0.06% manganese above the spec i fi ed maximum (1.05%) will be permitted up to a maximum of 1.35%.
3. All fl anges with primary service pressure ratings over 300 psi (2070 kPa) are annealed, normalized, or normalized and tem per ed.
The procedure for annealing consists of allowing the forgings, immediately after forging or rolling, to cool to a temperature be low 1000°F (538°C). They are then reheated to a temperature be tween 1550°F (843°C) and 1700°F (927°C) to refi ne the grain and al lowed the cool uniformly in the furnace.
The procedure for normalizing consists of allowing the forgings, immediately after forging or rolling, to cool to a temperature be low 1000°F (538°C). They are then uniformly reheated to a tem per a ture between 1550°F (843°C) and 1700°F (927°C) to refi ne the grain and allowed to cool in still air.
The procedure for temperating consists of heating the forgings to a temperature between 1100°F (593°C) and the lower trans for ma tion temperature for 1 h/in. of maximum section thickness.
4. After hot working and before reheating for heat treatment, the forg ing is allowed to cool substantially below the transformation range.
All forgings are furnished in the normalized, or in the normalized and tempered, or in the quenched and tempered condition de scribed by the following procedures:
Normalize: Heat to a temperature that produces an austenitic struc ture, holding to this temperature for suffi cient time to attain uniform temperature through out the material. Cool uniformly in still air.
Normalize and Temper: Subsequent to normalize, reheat to 1100°F (593°C) minimum, holding at temperature 30 min/in. of max i mum thickness, but in no case less than 30 min. Cool in still air.
Quench and Temper: Heat to a temperature that produces an auste nit ic structure, holding suffi cient time to attain uniform tem per a ture throughout; quench in a suitable liquid medium by im mer sion, reheat to 1100°F (593°C) min. holding at temperature 30 min/in of maximum thickness, but in no case less than 30 min. Cool in Still air.
5. The material conforms to the requirements for impact properties in Table A when tested at the applicable standard temperature in Table B.

6. The ferritic grades and the martensitic grades are annealed, or normalized and tempered. If furnished in the normalized and tem per ed condition, the tempering temperature for Grade F1, F2, F11 and F12 should not be less than 1150°F (620°C). The minimum temperature for Grades F5, F5a, F9, F21, and F22 is 1250°F (677°C).
7. All austenitic material is furnished in the heat-treated condition. The heat treatment consists of heating the material to a minimum temperature of 1900°F (1040°C) and quenching in water or rap id ly cooling by other means.
