HDPE Gauge Plating and Lining, HDPE Lining Basic Installation Steps

This Video Illustrate the highest quality polyethylene pipe lining systems for superior protection against internal pipeline corrosion and abrasion.
HDPE Lining Basic Installation Steps
Basic Steps:
Step 1. The host steel pipeline is subdivided into appropriate pull section lengths for HDPE liner insertion.
Step 2. On the job site, shorter lengths of HDPE liner are thermally fused together, creating longer monolithic lengths to match the steel pipe segments.
Step 3. A cable or Kevlar rope with a sizing plate and blow-down pig is sent through a steel pipeline section.
Step 4. At the opposite end of the steel pipe pull section, the cable is attached to a pull-head on the matching HDPE liner.
Step 5. The HDPE liner is pulled through a roller reduction box prior to entering the steel host pipe. The radial compression of the HDPE liner allows it to temporarily fit within the inner diameter of the steel pipe. This reduction in the HDPE liner’s outer diameter is maintained due to axial tension during the pulling process.
Step 6. Once the HDPE liner has been pulled completely through the host pipe, the tension is released and the HDPE expands, allowing the liner to form a “friction fit” against the steel.
Step 7. Specially machined HDPE flange “stub-ends” are used to iso- late the lined segments. Steel compression rings are utilized to ensure a leak-free connection between the HDPE gasketed steel flanges.
Step 8. The lined segment is thoroughly tested prior to bolting up the steel flanges at which point the pipeline is ready to be placed back in service.

Finally decided they wanted to pull more pipe, but waited to long, pipe began to expand back to original size in host pipe and then pulled the pulling head off and even though the pulling line is weighted, I would not have let the two workers walk out near the head of the pipe.....and then it broke...safety, safety, safety!

Safety first

I work at AtkinsRéalis Brazil's office. I am working in a project which this technology could be the best solution in our case. Do you know any company that realize this process that I can get in touch with. So we can discuss more deeply this kind of lining? Like the restriction, bends, maximum length per section, local infrastructure...
