reference laboratory, Laboratoire National de Métrolo- gie et d’Essais (LNE), expanding its use for gas applications in new Middle East and Africa markets such as Algeria. P6006 pipes are lightweight, flexible and leak-free,
and have a long life service, says Sabic. “Plastics pipe systems will continue to replace more

In addition to innovations in project management – in
order to install pipe with minimal disruption, for example – the project also relies on a new type of pipe from GPS. The company has, for the first time, produced 800mm PE100 gas pipe in the UK – for which a new approval process was needed. “Prior to this, the largest pipe was 630mm,”
O’Sullivan said. Earlier, Steve Kaye, head of innovation at Anglian
Water Services, told delegates that his company had recently begun looking into the use of oriented PVC (PVC-O) as a potential replacement for conventional PVC pipes – as it was more resistant to embrittlement, and far less likely to undergo catastrophic bursting. It can also better cope with surge pressures. “PVC-O was the best of all the plastics for coping
with surge – and all plastics fared better than ductile iron,” he said. A longer report on the Plastic Pipes in Infrastructure conference will appear in the next issue of PPE.
North African approval Sabic says that one of its PE100 compounds – HDPE P6006 – has recently been approved for use in gas applications in North Africa, following its approval by a number of standards bodies.
Egeplast’s HexelOne has been certified by the DVGW for gas and drinking water applications
traditional materials such as iron, concrete, and clay, which are more expensive to produce and install and more costly to maintain once in the ground,” said Abdullah Al-Otaibi, director of pipe and utilities, global segments, at Sabic. Another significant example of the use of HDPE P6006 is in its selection by China to transport natural gas to millions of residences as part of China’s Green project. At last year’s K2016 show, the company completed
its Vestolen A pipe portfolio by adding a new orange HDPE grade that is typically used for gas distribution. The grade, Vestolen A 6060R, is long-lasting and typically used for mono- and multi-layer co-extruded pipes. It has good resistance to slow crack growth and rapid crack propagation – as it is classified as a PE100 compound – and comes with a 10.0 MRS (Minimum Required Strength) rating. Die deposits are reduced, meaning that there are
fewer interruptions to the production process – leading to higher throughput levels. Ralph Handstanger, technical marketing engineer for HDPE in Europe, said: “When developing new materials, we pay particular attention to the conversion process. Vestolen A 6060R is an example how we support converters to optimise their production process.”
Offshore partnership Victrex has strengthened its strategic partnership in composite pipe for the oil and gas industry, by investing £10m in its development partner, Magma Global. It follows Magma’s launch of its M-Pipe, which uses Victrex Peek. The technology is expected to reduce
