2 Since then Marley Plumbing has become the market leader in the manufacture and distribution of plumbing products to the merchant 1991 Marley Plumbing entered the Pressure pipe market and now offers a range of uPVC and PVC pipe , as well as a range of Pressure bends, tees, valves and other 1999 Marley international was bought by the Belgium based Etex group; already operating globally in the construction and piping 2001 the Etex group acquired the global operation Glynwed pipe Systems resulting in the merger of Glynwed pipe Systems Africa and Marley Plumbing to form the new company Marley pipe Systems. This new company offers pipe systems in uPVC, mPVC and High Density Polyethylene in a range of sizes from 16mm up to 630mm in diameter. In addition, a vast range of fittings and joining systems is also available from Solvent Weld fittings and integral Rubber Ring Joints to Buttwelding and electrofusion.

3 Other mechanical joining systems are also available from top of the range metal clamping systems to an extensive range of compression some 400 personnel, Marley pipe Systems has manufacturing facilities at Nigel in Gauteng Province as well as at Port Shepstone in KwaZulu-Natal. The distribution network encompasses 8 branches around the country as well as sales offices in Namibia and Botswana, coupled with an active export division selling into Africa, the Indian Ocean Islands, Europe and June 2003 Marley pipe Systems became part of the newly formed Belgium based Aliaxis group of companies. Specializing in plastic pipe reticulation systems, Aliaxis operates in 37 countries through over 100 companies, generating sales in excess of Billion (Polyvinyl Chloride)PVC Pressure PipeApplicationsMarley pipe Systems Hydro-Wall (uPVC Pressure pipe SABS 966 Part 1) and Aqua-wall (mPVC Pressure Pipes SABS 966 Part 2) may be specified with confidence for pumping mains and reticulation networks.

6 The joint incorporates a factory fitted rubber sealing ring which is retained in position by a polypropylene lock ring. Each joint is capable of handling some expansion and contraction as well as angular deflection. The seal ring is designed to provide a watertight joint at high and low length of pipe has a "depth of entry" mark on the spigot end to ensure correct installation (see our Code of Practice Manual).The seal ring s ribbed profile reduces friction during seal, firmly fixed into the correct position with a polypropylene lock ring. This prevents accidental displacement of the seal ring during jointing. Factory assembly ensures that the supplied joint is fully functional. No more concern about joint failure due to the use of randomly sized or incorrectly placed for Pressure pipe A wide range of complimentary fittings is available for use with Hydro-Wall and Aqua-Wall Pressure pipes.

7 For sizes up to 250mm diameter, there are PVC bends, sockets and adaptors as well as a wide variety of SG Iron fittings. Larger sizes can be catered for from a selection of plain ended fabricated steel fittings in conjunction with Viking Johnson FittingsPVC BendsAll bends are made to suit either Class 9 or Class 16 applications and are available in 11 , 22 , 45 and 90 Diameter A (mm)Overall Length B (mm)Radius C (mm)Mass (kg) Diameter A (mm)Overall Length B (mm)Radius C (mm)Mass (kg) Pressure Bend45 Pressure Bend8 Outside Diameter A (mm)Overall Length B (mm)Radius C (mm)Mass (kg) PVC ACPVCO utside Diameter A(mm)AC PipeNominal Size(mm)AC PipeActual outside diameter C(mm)50506963506975759690759611010012212 5125150140125150160150177200200232250250 286 Outside Diameter A (mm)Overall Length B (mm)Radius C (mm)Mass (kg)
