Polyethylene (PE100) pipes are the backbone of Australia’s essential service networks—delivering drinking water, gas, irrigation, and industrial process fluids safely and reliably every day. With a design life exceeding 100 years, these durable, sustainable systems are built to stand the test of time—but only when every step from design through installation meets rigorous standards.
For a PE pipeline to achieve its intended century-long service life, it’s not enough for the pipe itself to meet Australian Standards. The system’s longevity depends equally on correct design, installation, and above all, welding practices. The Plastics Industry Pipe Association of Australia (PIPA) has long championed best practice through the development of key industry guidelines, including POP001, POP001A, and POP003.
These guidelines provide essential advice on safe, reliable electrofusion and butt fusion jointing—covering everything from surface preparation and temperature control to post-fusion inspection and record keeping. They are recognised in national standards, industry codes, and project specifications across Australia.
As PIPA Executive General Manager Cindy Bray explains, “The biggest single contribution to a successful fusion weld is the competency of the welder and their dedication to correct procedures.” Qualified welders trained to national competency standards (such as PMBWELD301E and PMBWELD302E) are fundamental to ensuring asset integrity and long-term performance.
PIPA also recommends welder re-accreditation every two to three years to maintain alignment with evolving technologies and standards.
PE pipelines are a vital investment in Australia’s future infrastructure. Ensuring their performance over the next century depends not only on the quality of the material, but on the people, processes, and best practices behind every weld.
