Steel is currently used worldwide for gas transmission onshore for gas pressures above 10 bar. An initial worldwide state-of-the-art study has shown that plastic composite piping systems can be an attractive alternative to steel. However, there are still some aspects that need further investigation in order to ensure the safe and secure use of plastic composite as main line for regional lower pressure transmission lines (10-45 bar), as main line for higher pressure main transmission networks (>45 bar) and as by-pass lines for maintenance and repair activities. 

In addition to integrity properties, aspects such as inspection methods, above-ground detectability, repair methods, transport capacity and suitability for future gases like hydrogen would also need to be studied. 


This project will incorporate studies and tests to fill the gaps identified between current state-of-the-art and fit-for-purpose plastic composite piping systems for onshore gas transmission. It will include cost-benefit analyses (capex and opex) of steel versus composite pipe systems. The project will result in an industry guideline to be further developed into a recommended practice.  


  • A faster installation and a non-corrosive alternative to steel, with lower total cost of ownership (TCO)
  • A universal international standard for this new application.


TCO of plastic composite piping systems can be considerably lower than for steel, mainly because of faster installation techniques and lower maintenance costs (no corrosion, i.e. no need for cathodic protection). In this JIP the reduction in the TCO will be quantified for different applications in onshore gas transmission.
