M-Gel Pig is a highly flexible solid gel pig with shape memory properties used in situations where a mechanical pig cannot be applied. M-Gel Pig can be propelled with any gas or liquid, and it is not sensitive to sour environments. The situations more commonly seen are when there are no launcher or catcher facilities, when there are changes or variation in a pipeline’s internal diameter, and when there is a high risk of sticking due to wax, debris or scale build up. M-gel is also applied to aid in the recovery of stuck/stalled mechanical pigs, in conjunction with batch treatment chemicals in gas lines, or sent through coiled tubing for liquid displacement.
M-Gel Pig is capable of extruding through chokes and restrictions up to 50% of its diameter and returning undamaged to its original size and shape once through. Beyond this 50% reduction the pig will self-destruct eliminating the risk of sticking or the need to catch the pig in a traditional receiver.
