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
- Resists heavy hydrocarbons
- High resistance to both Slow Crack Growth (SCG) as well as Rapid Crack Propagation (RCP)
- Improved installation effiiciency
- Flawless function
proven record of performance
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.
A GAS LINE GOES UNDERGROUND
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.
Transport of biogas from landfill
Since the end of 2017 a 22 km long gaspipeline in Fortaleza, Brazil, transports the methan evolving from a landfill to the city.
