Onshore

An Extreme World Needs Extreme Materials

The flexible tubes used for the transportation of oil and gas are under enormous physical and chemical stress. With Kynar® polyvinylidene fluoride (PVDF), Rilsan® and Rilsan® Fine Powders (PA) biosourced polyamides, Arkema provides a wide range of solutions to protect them against corrosion, chemical attack and aging. These high performance polymers are also routinely used for coating pipes and flexible tubes in oil and gas installations. In these conditions, they are subject to extreme pressure and fluid constraints.

Gas Distribution

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, light weight, and lower lifetime cost than steel make 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

 

Safety Benefits

  • Excellent resistance to slow crack growth and rapid crack propagation
  • No cathodic protection needed
  • Complete range of fittings, couplings, ball valves, and risers
Yellow coiled natural gas lines.

Gas Gathering

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.

Kynar Flex® PVDF and Rilsan® PA11 are extreme materials that can hold up to the demanding conditions that downhole wires & cables are subject to. Kynar® resin’s resistance to harsh chemicals and heat make it useable in numerous applications including electrical downhole cables, fiber optic downhole cables and hybrid electric/fiber cables. Its compatibility with the many different types of materials, pressures, and temperatures make it a choice that brings ease of process when manufacturing and installing the cables. Rilsan® PA11 is a 100% biobased polymer with attributes including abrasion resistance, toughness, and low moisture pickup which ensure a long product lifetime under extreme conditions.

 

Oil & Gas producers demand products that can be relied on. With decades of trusted use in oil & gas wells around the world Kynar Flex® PVDF and Rilsan® PA11 are considered preferred solutions for downhole applications.

Gas Station Piping

Kynar® PVDF has been a proven solution for over 50 years for the Gas Station Piping application. Kynar® PVDF and Rilsan® PA11 and PA12 have UL approvals and their resistance to alcohol content and dimensional stability give the materials lasting power for gas station piping.

Liners made of Kynar® PVDF or Rilsan® PA11 provide internal corrosion protection for both rehabilitation projects and new construction. In both scenarios customers can find significant savings in both capital and operating expenditures when compared to steel pipe replacement.

 

Rilsan® PA11 is 100% based on renewable resources, and contains low moisture uptake, excellent resistance to chemicals, and low permeability to hydrocarbons. 

 

Kynar® PVDF can be used for higher temperature requirements while still maintaining resistance to harsh chemicals, hydrocarbons and gases.

Pipe Coating

Pipe coated with Rilsan®

Rilsan® fine powders have a high resistance to hydrocarbons and other petrochemicals which helps limit corrosion of the pipes used to transport these fluids, effectively extending the service life of these pipes. The high flexibility of our materials give them an advantage over brittle epoxies and other thermoset coatings. The extreme properties of Rilsan® fine powders can be used to protect a range of accessories in petrochemical applications including pumps, valves and fittings.

 

Rilsan® fine powders high performance over long periods of time make it a cost effective and trusted solution for coating applications in the Oil & Gas market.
