Hundred club: developments in PE100 pipe
Recent developments in PE100 pipe include a major installation in Spain, its use in irrigation pipe by a sugar manufacturer and a pipeline renewal project in the UK – replacing GRP pipe

PE100 is one of the main grades that specifiers choose for demanding pipe applications. It can be used in a variety of industries – from gas to water transport – but in each case is typically selected for its high level of robustness. Recently, Kier Infrastructure installed more than
13km of Aliaxis PE100 pipe in a UK pipeline renewal project. The project will replace existing glass-reinforced pipe (GRP) – which tended to rupture and leak – with GPS PE Blue pipe from Aliaxis. The pipe will upgrade the connection from a pumping station to a reservoir to deliver potable water to residents of the Cotswolds. PE100 pipe, 1200mm in diameter, will replace the GRP pipe, which was originally installed around 20 years ago – and had consistently failed. The design of the new pipeline started around eight years ago – which included advice on the installa- tion and benefits of PE100.
“It was decided to lay the majority of this 30 PIPE & PROFILE EXTRUSION | March/April 2023
replacement pipeline in PE due to its flexibility and speed of installation,” said Nigel Gascoyne, key account manager at Aliaxis UK. “We’re the only company in the UK that can produce PE100 pipe to 1200mm sizes.” Andy Muncer, project director at Kier, added:
“While we considered a steel pipe, we selected the GPS PE Blue as a proven, economic solution. There is an agreed call-off schedule, for which Aliaxis is storing pipe at an airfield.” The offsite storage allowed Aliaxis to secure available raw materials and begin production early – and to manage a controlled delivery schedule with limited on-site space, he said.
Low-sag pipe Politejo, a pipe manufacturer based in Portugal, has selected a low-sag PE100 material from Borealis for a new pipeline project. The material, BorSafe HE3490-SLS-H, has a tailored polymer architecture and low melt flow
