ABS Pressure Fittings Plain/Threaded (BSP) - Reducing Bush
ABS (Acrylonitrile butadiene styrene) is an extremely robust thermoplastic pipework system used by many industries in systems for food and beverage production, sewerage and water treatment etc. ABS is extremely resistant to impact with good resistance to chemicals, is non-toxic. Conforming to the toxicological requirements of the British Plastic Federation, British Industrial Biological Research Association Code of Practice for Food Usage 45/5, and EEC requirements for plastic materials in contact with foodstuffs. These systems are light, strong and simple to fit using a solvent cement. ABS Products are clearly identified by their light grey colour. Epco supply a variety of ABS plain/thread P/T fittings including ABS socket, ABS 90 degree elbow, ABS Tee, ABS tank connector, ABS male thread adaptor, ABS female thread adaptor, ABS reducing bush, ABS barrel nipple, ABS union, ABS hose adaptor, ABS brass female composite union and ABS brass male composite union WRAS Approval ABS is approved by the Water Research Advisory Scheme for use with potable water. Standards ABS pipe is manufactured in accordance with BS5391 Part 1 ABS fittings are manufactured in accordance with BS5392 Part 1 Chemical Resistance ABS has good resistance to a wide range of diluted inorganic acids, organic acids, salts, animal fats and oils. ABS is not resistant to organic solvents, alcohol, petrol, acetic acid or vegetable oils. For information on specific chemical resistance for ABS please contact our Sales department. ABS System Pressure/Temperature Relationship Pressure ratings for plastic pipework systems are always quoted at 20°C, it is a fundamental principle of such systems that if the temperature is increased then the pressure rating must be reduced. ABS systems should never be used for temperatures in excess of 70°C. The following Table gives a rough guide as to the temperature/pressure relationship of ABS pipework systems.
