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, 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

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

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.

Rilsan® PA11 Applications for Gas Gathering (Unregulated)

  • Up to 315 psi, DR 11
  • Up to 390 psi, DR 9

Liner

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

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 gives 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 makes it a cost-effective and trusted solution for coating applications in the Oil & Gas market.

Reinforced Thermoplastic Pipe

The light weight and flexibility of reinforced thermoplastic pipes made from Rilsan® PA11 and Kynar® PVDF allow for Oil & Gas customers to deliver the pipes in rolls, which allow for quicker and easier installations.

Key Benefits:

  • Compatibility with aramid fibers
  • Flexibility
  • Lightweight
  • Lower cost installation
  • Resistance to harsh chemicals
  • Resistance to high and low temperatures
