Nylon Pipe Rolls Out in the Oilfield


The world's largest nylon producer has introduced nylon transmission pipeline that can withstand temperatures up to 200°F and pressures up to 500 PSI.

Raptor 6,6 homogenous single-wall line pipe is a first for the global oil and gas industry, according to Wichita, KS-based Invista.

Raptor comes in 2,000-foot sections "that are ready for the ditch," the company says. The line is fabricated from nylon 6,6, which boasts "superior strength, heat tolerance and wear resistance," according to Invista.

Raptor resisted abrasion better than steel and high-density polyethylene when tested against three-inch .188 ERW A53/x42 steel and 4710 HDPE, the manufacturer says.

"Steel rusts; others bust," the company says in a product video that calls Raptor "a brand-new breed of line pipe."

Applications include multiphase flow lines, low-pressure natural-gas gathering, and water transportation. The product comes in two-, three-, four- and six-inch IPS and SDRs 7, 9 and 11. Six-inch pipe is expected to be available soon.

Features and Characteristics

Raptor's technical team "kept corrosive liquids, impacts, abrasions, high temperatures, and daily wear and tear from the oil patch top-of-mind" when developing the pipe, the company said.

According to Invista, Raptor also:

  • Installs quickly ("unroll it, drag it out, and throw it in the ditch");
  • Requires no de-rating for liquid hydrocarbons; and
  • Has better impact resistance than fiberglass, HDPE and their composite pipes.

Raptor comes in 2,000-foot sections. A video describes the installation process as "unroll it, drag it out, and throw it in the ditch."

“We discovered a strong market signal for a line pipe that was tough enough to handle the oil patch and perform daily under rugged conditions, but could be installed quickly, which provides E&P and midstream companies flexibility in their schedules,” said Invista VP Vikram Gopal.

Testing Results

Raptor nylon pipe has been "installed, tested and subjected to accelerated wear in varied environments to confirm its strength and durability," according to the manufacturer.

"The combination of the product’s resistance to corrosion, impacts and abrasions are unmatched by other line pipes, including steel."

With brands including Lycra, Stainmaster and Antron, Invista is one of the world’s largest integrated producers of chemical intermediates, polymers and fibers. The company has about 10,000 employees across 20 countries.
