TDW 16 inch Ultra Pig – Purging Excellence

TDW Ultra pig in action

When an Ohio Gas and Liquids operator called for advice on a pig for a run on a 16 inch 4-mile condensate line needing to be thoroughly purged, Kerr and TDW were on hand to support.  The line needed purging in order for needed repairs to take place. 

After visiting the launch site and discussing with the customer their requirements, the 16 inch Ultra Pig with four Ultra discs was selected.  This all-urethane pig (less nuts, bolts, and washers)  also carried two transmitters. One transmitter acting as a back-up was secured in the front part of the cavity body during the run. 

The design of the discs on the ultra-pig are ideally suited to carry out purge operations due to their shape. A key differentiating factor is that the ultra-disc is thicker than the regular sealing discs. As the ultra-disc wears, it has more urethane touching the pipe wall.

Kerr attended the launch and followed up to see how the run went.  The line was successfully purged of the condensate and the repairs on the condensate line were able to proceed.
