Bi-Directional steel bodied pigs are designed to travel in either direction in a pipeline. The primary use of Bi-Directional pigs is liquid displacement during the hydrostatic testing stage of construction, but they can also be used for cleaning, separation and batching. All of Apache’s Bi-Directional pigs are fitted with discs made from our wear resistant Reliathane urethane.

UNIVERSAL TRANSMITTER PIGS 6 – 14″ (152 – 356 MM)

Apache is pleased to introduce our newly revised Universal UT mandrel design. With the changes in design only one mandrel is required to make any configuration of pig. The UT is the only steel mandrel small diameter pig that Apache manufactures with a transmitter cavity in the middle of the mandrel to accommodate electronic pig tracking equipment. They can also be used for cleaning and batching of dissimilar fluids. The mandrel can accommodate any configuration of cups, discs and brushes. Standard bumper noses prevent damage to both the pig and in-line auxiliary equipment.

ED BI-DIRECTIONAL 3 – 14″ (76 – 356 MM)

The ED version, with a combination of 4 sealing discs and 2 guide discs, offers a sealing arrangement suitable for separation of dissimilar fluids or for dewatering during hydrostatic testing.

Designed to traverse 1.5D bends.
