Gas Station Piping
Arkema offers multi-layer piping solutions with Kynar® PVDF, Rilsan® PA11 and PA12 and Orgalloy® PA6. By using Kynar® PVDF for its chemical resistance on the inside of a pipe, and Rilsan® resins as the main structure, Arkema offers a chemically and physically strong solution for the gas station piping application.More Information
Arkema's Rilsan® PA11 grade for regulated gas transmission and distribution has recently been DOT approved in CFR 49 Part 192 for pressures up to 250 psi. Rilsan® PA11 provides higher operating pressures compared to polyethylene while also providing lower installed cost and total lifetime cost compared to steel – PA11 is corrosion-free and requires no costly cathodic protection. A complete system of couplings, fittings, valves and risers is available and the installation equipment is identical to polyethylene pipe.More Information
Wire and Cable
The primary use of Kynar® PVDF for the oil and gas business is in the manufacture of offshore and downhole cables, which are primarily TEC (tube encapsulated cables) for “flat packs.” Kynar Flex® PVDF is ideal for the TEC application since it gives the wire and fiber optic cables the ability to withstand water permeation, abrasion, mechanical abuse, temperature extremes and corrosive chemicals.More Information
With a proven track record of quality and performance, Rilsan® PA11 is a known and trusted solution within the gas distribution market. Its range of application sizes from 2 to 6 inch pipes make it available for various applications.
Recently approved for pressures up to 250 psi, Rilsan® PA11 is a D.O.T. Permitted Plastic for High-Pressure Natural Gas Pipelines.
Its combination of chemical resistance, lightweight, and lower lifetime cost than steel makes it an ideal solution for gas distribution.
Lower Cost Benefits
- Coiled pipe that can be plowed or planted
- Installation using existing PE installation equipment
- Joining by butt fusion
- Corrosion resistance
- Excellent resistance to slow crack growth and rapid crack propagation
- No cathodic protection needed
- Complete range of fittings, couplings, ball valves, and risers
Rilsan® PA11 has advantages over steel in the gas gathering market including its cost effectiveness and corrosion resistance. Its higher psi range give it an advantage over current polyethylene solutions. In an industry moving towards regulation, Rilsan® PA11 is a safe choice given its current safety approvals for other Oil & Gas applications.
