High DP (plugging) Pigs

High DP Pigs or Plugging Pigs are specialist pigs that can be used to isolate a section of pipeline at pressure while some remedial work is undertaken. High DP / Plugging Pigs can withstand pressures up to 200 bars typically. The plug works by gripping into the line pipe and then having a separate sealing system. Lower pressure techniques include High Friction pigs, which provide a barrier for depressurised systems.
