The VESTAMID® NRG grades for oil and gas applications have been developed for manufacturing high caliber pipes. They feature very constant processing properties without variations. High caliber tubing with constant diameters and wall ticknesses can be produced due to the high melt stiffness of the polymer.
Subsea umbilicals, risers, flow lines (SURF) And TCP / TCR
Thanks to its exceptional resistance to mechanical stress, stress fracture and chemicals such as crude oil, VESTAMID® NRG is used for the outer and inner protection of pipelines. Pipes with thermoplastic composites (TCP, TCR) contain the polyamide 12 in the outer and inner layers and also in the composite matrix.
Gas pipelines in the distribution network have to withstand more than 10 bar of pressure. Until now, they have usually been made of steel. VESTAMID® NRG is the high-performance alternative that gas suppliers can use to effectively build their underground pipeline network, including trenchless installation methods.
For gas production, black steel pipes are significantly more convenient and much more easily available than the currently used stainless steel pipes. But they are also much more susceptible to corrosion. Black steel pipes with VESTAMID® NRG liners, on the other hand, are protected against internal corrosion and in addition offer enormous weight and price advantages.
Steel pipe coating
VESTAMID® NRG provides a flexible, mechanically resistant coating system, which combines the advantages of a polyethylene coating and a cement covering. In this way, industrial pipes are effectively protected and are also suitable for alternative installation methods.
Three kinds of materials are available for the demanding field of oil and gas components:
- Polyamide 12 VESTAMID® NRG
- Polyether ether ketone VESTAKEEP® PEEK
- Polyimide P84®
