Tool remotely repairs plastic pipelines.(PROCESS TECHNOLOGY)

Advanced Materials & Processes, April, 2007

A unique tool that can remotely repair plastic natural gas distribution pipelines without disrupting natural gas flow has been developed by Timberline Tool, Whitefish, Mont., under a cost-shared project with the National Energy Technology Laboratory. The tool applies a thermal-chemical patch to repair nicks and gouges or worn spots in the polyethylene pipe.

The portable, lightweight tool has an open-jaw configuration that can fully encompass the pipe, so it can be operated by a single worker from the top down without the need to fasten the device under the pipe.
