to longer service life in these application areas. The PE2708 material is more than four times as
resistant to slow crack growth compared to the PE4710 requirement, and offers less stiffness and greater ductility, says the company. Combined with reduced weight, this helps in field handing and installation. It also has the same fusion parameters as PE4710 material. The pipe is available in a full range of sizes and pressure capabilities.

M-Pipe should reduce exploration and production costs and risks in subsea applications
as well as aggressive media. “It comes at a time when the oil and gas industry is
searching for cost efficiencies, and developments in lightweight and durable solutions,” said Norner. Polymers offer advantages such as corrosion
resistance, insulation and buoyancy, it added. “We provide testing according to international
standards at high temperature and pressure, functional testing and specially designed test programmes,” said Henning Baann, business director at Norner. “We ensure that samples are tested in such a way that they simulate the specific environment and conditions relevant for the application such as H2
S, CH4 and CO2 .”
Abrasion boost Performance Pipe, a division of Chevron Phillips, has released a new polyethylene (PE) pipe with enhanced abrasion resistance – making it suitable for applications in industrial and energy applications such as mining, and oil and gas gathering. The DriscoPlex 4800 series PE pipe is made from black medium-density polyethylene (MDPE) that conforms to ASTM F714 and D3350. Testing has shown that the pipe provides at least 30% greater abrasion resistance than other HDPE pipes tested – translating
Sub-sea partner Victrex has strengthened its strategic partnership in composite pipe for the oil and gas industry, by investing £10m ($13m) in its development partner, Magma Global. It follows Magma’s launch last year of its M-Pipe, which uses Victrex Peek. The technology is expected to reduce exploration and production costs and risks for demanding subsea applications. “Our strategic relationship with Magma Global will
help to further facilitate the industry’s move into a new era of enhanced capabilities, coupled with reduced costs, in extreme subsea operations,” said James Simmonite, energy director at Victrex. The need to operate at greater depths, with sour ser-
vice demands, and under higher pressures and temperatures, has made a metal replacement for subsea piping an urgent priority for the industry, according to the company. According to its annual report, Victrex sold more than £1m of Peek to Magma in 2016. At the same time, Magma has signed an agreement with JDR, which will see it combine its M-Pipe with JDR’s subsea cable and umbilical technologies. The agreement includes research, development and
qualification of testing that will allow the two companies to find new ways of reducing the cost – and extending the life – of offshore oil and gas projects. Charles Tavner, Magma’s chief operating officer, said: “Looking at how we might combine M-Pipe with JDR’s products makes complete strategic sense.
Researchers embed sensors into pipe
Scientists at the University of Manches- ter in the UK are looking to develop composite pipelines that incorporate embedded sensors. The project, which is supported by BP,
aims to use piezoelectric wafer active sensors (PWAS) and distributed optical strain sensors (DOSS) – as well as infrared thermography (IRT) – to allow

structural monitoring of pipes in real time. “At the end of the project we will have a set of lab prototype composite pipelines with self-sensing capability,” said the researchers. PWAS was used to measure acoustic
emissions during impact tests, and results from this picked up damage to the

fibres and polymer matrix. While IRT also identified damage, it
was restricted by the depth to which it could analyse the material: the research- ers said that shallow sub-surface cracks can mask any damage that lies under- neath.
The original research appeared in the journal Applied Composite Materials.
