Invista introduces nylon 6,6 pipes that withstand harsh oilfield conditions

  • Nylon pipe withstands 93°C /pressure up to 34 bar
  • 25 times more abrasion-resistant than HDPE pipe
  • Application: harsh oilfield environment

Invista, a subsidiary of Koch Industries, introduced Raptor nylon pipe, a nylon 6,6 single wall pipe that withstands temperatures up to 93°C (200°F) and pressures up to 34 bar (500 PSI).

Key features of the nylon pipe

The pipe has been installed, tested and subjected to accelerated wear in varied environments to confirm its strength and durability. According to the company, the nylon pipe performs 2 to 5 times better than steel* in abrasion resistance. It offers better resistance to static build-up and more than 25 times more abrasion resistance than HDPE* pipe. It has also better impact resistance than fiberglass, HDPE and their composite pipes. And due to its resistance to a wide range of corrosive liquids, the pipe requires no de-rating for liquid hydrocarbons.

Ease of installation as an advantage

Raptor nylon pipe comes coiled in up to 2,000-foot sections that are ready for the ditch and suitable for applications ranging from multiphase flow lines to low pressure natural gas gathering and water transportation. Typical installation of the pipe requires only a fraction of the time needed to install other line pipe such as steel. Standard butt-fusion technology and a range of available transition fittings can be used for the connection of pipe sections.

The pipes are available in 2-inch, 3-inch, 4-inch and 6-inch IPS and SDRs 7, 9 and 11. Six-inch pipe is expected to be available in fourth quarter 2014.

*Tested against 3-inch .188 ERW A53/x42 steel and 4710 HDPE
