Epoxy Barrier Coating

Those involved in the rehabilitation of pressurized piping systems are invited to participate in the development of a proposed new standard, WK24231, Practice/Guide for Internal Nonstructural Pipe Epoxy Barrier Coating Material Used in Pressurized Piping Systems.

The proposed standard is being developed by Subcommittee F17.67 on Trenchless Plastic Pipeline Technology, part of ASTM International Committee F17 on Plastic Piping Systems.

“The technology covered in WK24231 allows for the re-use of existing piping systems that would otherwise need to be totally replaced,” says Sidney Cavanaugh, Cavanaugh Consulting, and chair of the F17.67 task group that is developing the proposed standard. “We need a consensus standard for this product so that it may be referenced in the model codes and allow appropriate code changes to clearly recognize and approve the technology.”

Designers, specifiers, regulatory agencies, owners, contractors and inspection organizations are among the potential users of WK24231. Cavanaugh says the task group is particularly interested in participation in the development of WK24231 from those involved in regulatory activities.
