SYNOPSIS

The use of plastic pipes in the internal plumbing system in high rise buildings to transfer potable water from the roof tank to the sanitary fittings inside the building is common and there is a wide of selection plastic pipes, reference to SPAN Table C.2 – Complying standards of pipes used in internal plumbing system. Many of these standards listed have yet to be updated except MS1058:2023.

The talk will focus on the latest MS 1058-3:2023 Polyethylene (PE) piping systems for water supply and for drainage and sewerage under pressure – Part 3: Fittings (Previous MS1058-3: 2006 Polyethylene (PE) Piping Systems for Water Supply- Part 3: Fittings) lapse of 17 years.

The description of the title of the revised MS1058 has changed hence widening the applications of HDPE pipe from the 2006 version. The talk will focus on the SOCKET FUSION joint which has significantly expanded the sizes from previously OD 20 to 32 to OD 16 to 125.

Socket and fusion joint currently relates to PPR pipe, MS2286-3: 2012 Plastic piping systems for hot and cold water installations – Polypropylene (PP) Part 3: Fittings therefore with the updated MS1058-3:2023 socket and fusion joint will also be used for HDPE pipe for the internal plumbing system.

Practical hands-on experience to do the socket and fusion joint on HDPE and PPR will be available for participants, courtesy of Azeeta Pipe Sdn Bhd a manufacturer of both type of pipes. A sample of the HDPE mechanical joint available too for participants to understand the differences of different type of joints.
