ABS PIPE SYSTEMS

ABS Pipe, ABS Fittings and ABS Valves for low temperature fluid transportation




Durapipe ABS Pipe Systems combines corrosion resistance, toughness and economic benefits to provide tremendous advantages for low temperature fluid transportation.

ABS is a solvent welded, fully matched pipework system incorporating ABS Pipe, ABS Fittings and ABS valves that is available in both imperial and metric sizes.

ABS provides a wide temperature range and the system remains extremely ductile even at temperatures as low as -40°C. Furthermore, ABS is extremely lightweight and is much easier to handle on-site than traditional materials especially during installation which can significantly reduce both time and cost.

ABS Fittings pressure drop


The calculation of pressure drop in fittings is more complex but calculations can be made for equivalent lengths of straight pipe using the formula

E=F x D where:
E = equivalent pipe length (metres)
F = fittings constant (see table below)
D = fitting internal diameter (mm)

To calculate the total pressure drop in the system, the equivalent straight pipe lengths for fittings is then added to the total straight pipe length to obtain the total drop.
The values are included as a guide to aid calculation of overall system performance and should not be used in isolation.

ABS Pipe supports


Pipe supports and clips should provide lateral restraint and allow free, unrestricted, axial pipe movement. Standard ‘drop rods’ may not provide sufficient lateral restraint and the SuperFLO ABS pipe could start to ‘snake’.

Durapipe Cobra clips are designed to meet these requirements. A suitable alternative would be mild steel saddle clips designed with a clearance between the pipe and the clip. All steel brackets in contact with the plastic pipe should be free of sharp edges to avoid damaging the pipe.

Support centres


The recommended distance between supports for SuperFLO ABS pipes filled with water is given in the table below. This table is based on the thinnest wall pipe in each size.

Where the contents have a specific gravity greater than 1, the distance must be decreased by dividing the recommended centre distances by the specific gravity. The details shown are for horizontal pipes. For vertical pipes, support centres may be increased by 50%.
