Rotationally Lining a 30" Diameter Elbow

August 17, 2018

This week we have been working on a challenging rotational lining project.

This 30” diameter elbow is one of five that our team is lining with HDPE, designed to be used with United Pipeline’s Weld Tite™ technology.

In service, this pipe carries brine in the process of storing hydrocarbon underground. By lining it with HDPE, it prevents the pipe from corrosion and leakage.

Due to the large size of the elbow, our team worked to manipulate the rotational lining machine in order to line the piece properly. The result was 0.400” thick liner in each elbow.

Please take a moment to view the video, which shows part of this process.
