VESTAMID® NRG For GAS Applications

Competitor to STEEL

The year 2004 saw the market launch of a new PA12 grade, VESTAMID® NRG, that satisfies the requirements on large gas pipes with external diameter up to 300 mm: The material withstands pressures up to 18 bar and is therefore suitable for distribution lines and industrial connections. Since December 2015 it has been included in the test specifications of the DVWG (the German Technical and Scientific Association for Gas and Water) with the title “Plastic piping systems in gas and water supply; GW335-A6: PA-U 160 and PA-U 180 pipes and their joints and jointing.”


All-plastic PA 12 pipes have many advantages over steel. Plastic piping can be wound so that about 150 to 200 meters fit on a roll; steel pipes, on the other hand, have a maximum length of 18 meters because they cannot otherwise be transported by truck. Plastic pipes therefore require far fewer weld seams when being laid, which reduces installation time and costs. Maintenance is also less costly because no cathodic corrosion protection (permanent current or sacrificial anode) is needed. Due to simpler assembly, easier handling, and lower maintenance costs, system costs are significantly lower with PA 12 than with steel.

The VESTAMID® NRG piping systems allow general working pressures to be increased by 25 % compared to similar high-pressure plastic materials. They are

  • Resistant and durable

  • Corrosion-resistant

  • Resists heavy hydrocarbons

They feature

  • High resistance to both Slow Crack Growth (SCG) as well as Rapid Crack Propagation (RCP)

  • Improved installation effiiciency

  • Flawless function

A number of VESTAMID® NRG commercial supply lines are now in regular operation. Pipe producers and installation firms are benefiting from this experience. The first installation in Germany (160 mm SDR 11, 16 bar) was in Beckum, North-Rhine Westphalia, in July 2017. Since 2005 global projects have led to installations in Brazil, Colombia, the US, and Indonesia with pipe diameters between 90 and 160 mm SDR 11 and SDR 13.6 and pressures of 14 to 16 bar.

Since late 2016, a 4.6 km underwater VESTAMID® NRG pipeline has been supplying the inhabitants of Tierra Bomba, an island off Colombia’s Caribbean coast, with natural gas. The video describes the entire project.
