High Friction Pig

High Friction Pigs are low pressure barrier pigs for pipeline isolation and sealing applications

Propipe High Friction Pigs are primarily used to provide a low-pressure, high seal isolation of pipelines, during maintenance intervention work, as well as during pipelay flooding and dewatering. They can be sized from 8” up to 48” and are able to be run up to 5km or 10km prior to use and over 600km after use as well as through features such as Wyes, Unbarred Tees and Check Valves. Pigs are suitable for safe back-loading into subsea PLRs as well as onshore Pig Launchers.

High Friction Pigs are also highly effective dewatering pigs and have been used for this application as well as for alternative applications such as stuck-pig removal and cable feed applications

In many instances, especially where divers / operators are expected, Propipe will produce a short pigging spool and perform verification testing prior to finalisation of the pig design.
