Evonik's Vestamid NGR nylon 12 has found use in natural gas distribution pipe.
The resin was used to make pipe for natural gas service lines in Ulm, Montana, where gas replaced propane for homeowners. Dura-Line Holdings Inc. of Knoxville, Tenn., extruded the nylon 12 pipe.
Evonik boasted that the nylon 12 pipe is more cost-effective than steel. The cost of steel pipe hindered the hookup of natural gas from a local pipeline to residences in Ulm.
“Working with this new high-pressure plastic material is very easy and safe,” noted Tony Pietrykowski, construction supervisor for Energy West Inc. a natural gas distribution company headquartered in Great Falls, Mont., that installed the nylon pipe. “We didn't need any special equipment and were able to use our current procedures to complete the project. Following the installation, we pressure tested the line at 400 (pounds per square inch gauge).
Operating pressure for the natural gas line is usually 150 psig.
