THE HDPE PIPE SYSTEM FOR DRINKING WATER PIPELINES

Providing quality drinking water to people is of global importance, and a core part of our business is to provide piping solutions for water applications that are economical and environmentally sustainable. The  Piping System is the No. 1 choice for all water supply lines, providing flexibility, longevity and economy.

Many of Perth’s ageing water mains are being replaced with HDPE pipe, reducing leakage and ensuring low maintenance in future.DRD’s  PE pipe has been extensively used throughout Perth City and throughout the old northern suburbs.  HDPE pipe is fully pressure rated, has Watermark approval, and can be fusion joined using electrofusion couplings, or butt welded. The black pipe with blue stripe helps identification as potable water pipe, and Pipe Marking Tape is also available. Polyethylene water pipe comes in 6 or 12 meter lengths, or can be made to order in custom lengths, also coming in coils of 50 to 200 meters.

DRD’s quality of service and flexibility as a WA manufacturer means  is a very popular piping product. With the large range of fittings, accessories, hire equipment, and training,DRDis your one-stop-shop for HDPE piping products.

Key features and benefits:

· Suitable for installation according to AS 3500.1:2003 “Water services”

· Blue Stripe for easy identification

· Heat-fused jointing systems create a monolithic structure that is stronger than the pipe itself, and completely leak-free. This eliminates rubber seals which can fail over time, also solving root intrusion problems, and provides pipeline integrity where installed in unstable ground. No dangerous chemicals or glues involved in jointing.

· No anchor or thrust blocks are needed to prevent joint blow-out when using heat fusion welded jointing. Correctly made heat fusion joints may be expected to last the life of the system and withstand thrust/end loads equal to the strength of the pipe/ fitting without adding external restraint or thrust blocking.

· Extreme flexibility of pipe allows cold bending to accommodate minor changes in direction.

· Large range of fittings available, providing flexibility of design.

· Pressure rating of PN12.5 (1250 kPa) or PN16 (1600 kPa) at 20°C, including safety factor of 1.25.

· Manufactured to AS/NZS 4130 “Polyethylene – PE – pipes for pressure applications” and AS/NZS 4129 “Fittings for polyethylene (PE) pipes for pressure applications”

· 20 mm to 110 mm diameter polyethylene water pipe is available in 50, 100, 150 and 200 metre coils. Larger diameters and custom lengths can be coiled to order.

· 25 mm to 630 mm diameter PE water pipe is generally available in 6 and 12 metre lengths. Lengths up to 22 metres made to order.
