EVONIK INDUSTRIES AG - Excellent UV resistance properties, well suited for long term outdoor applications
- Suitable for pressures up to 315 psi (22 bar) and elevated temperature service
- Complies with ASTM F3524 standard for Polyamide-12 Line Pipe
Essen/Marl, Germany. Evonik is adding another product to its portfolio of VESTAMID® NRG polyamide 12 (PA12) compounds specially developed for applications in the energy sector: VESTAMID® NRG 5901 is a UV-resistant, black compound suitable for above-ground installation. Compared to coated carbon steel pipe, the cost is about 30% lower because cathodic corrosion protection is not required, and installation can be done using low-cost techniques similar to HDPE pipe systems.
Gathering and flowlines are used in rural areas to transport crude oil, natural gas, or multiphase fluids from the point of production (wellhead) to a central collection point. Due to relatively high pressures and flow rates, these have historically been a market for carbon steel pipes, which must be protected against corrosion with appropriate measures during their service.
VESTAMID® NRG 5901 PA 12 compound is now available as a thermoplastic material that is insensitive to corrosion. Unlike polyethylene pipes, it can be used up to pressures of 315 psi (22 bar) for oil and gas gathering. According to the TR4 listing of the Plastics Pipe Institute (PPI, USA), the long-term hydrostatic stress (Hydrostatic Design Basis HDB) of polyamide 12 is rated for design temperatures up to 180 °F (80 °C). VESTAMID® NRG 5901 complies with ASTM F3524 standard for PA12 pipes. The compound is colored black and UV-stabilized, so that above-ground installations are also possible. Since the pipes can be coiled and thermo-fused, they can be installed using cost-effective methods benefitting from a wide range of readily available accessories.
Especially developed for applications in the energy sector, VESTAMID® NRG PA 12 compounds include products for pipelines for off-shore and on-shore oil and gas generation, gas distribution, liners and steel pipe coating.
The black polyamide 12 compound VESTAMID® NRG 5901 was developed for line pipes, suitable for above-ground installations (gathering pipelines). PA 12 line pipes save costs due to easy installation and low maintenance.
