Gel Pigs and Speciality Pigging Solutions for Unpiggable .

Gel Pigs and Speciality Pigging Solutions for Unpiggable Pipelines Gel Pigs are chemically constructed with a rigid or semi-rigid structure. Consequently, these pigs are ideal to use where conventional pigging is not possible, usually because of no launching or receiving hardware, tight bends or significant changes in ID.

US7475591B2 - Methods and systems for hydrostatic testing .

A sealing pig is introduced in the pipeline a pre-selected time or distance prior to the introduction of the first isolation tool. The sealing pig is typically a pig that does not include moving parts or communication systems but includes only cups or discs that extend from a central body to slidably engage the interior wall of the pipeline.

PIG Launchers and Receivers are Critical to Midstream .

Most pigging systems use bidirectional launchers and receivers that can work in either direction. This is important to allow the PIG to be retrieved by the launcher if there is a blockage in the pipeline which prevents it from reaching the receiver. PIG launchers and receivers come with safety valves and locking system to prevent accidents.
