Description:

“VDT Gauging Pigs are designed to indicate obstructions in a pipeline. The slotted aluminium gauge plates deform and stay deformed upon encountering an obstruction in the line. Since they are made of aluminium, they do not damage the internal surface of the pipe.
The pigs will traverse 1.5DR bends unless otherwise noted. They are not recommended for lines containing check-valves unless the valves can be locked in their open position.”

Feature:

“VDT pigs utilize polyurethane cups and discs. These cups and discs can operate in temperatures ranging from -18° C to 93° C .

The gauge plates are made from aluminium and are slotted in order to deform locally when an unacceptable obstruction is encountered, while still allowing the pig to travel through the pipeline. In the case of severe obstructions, the pig may get stuck in the line.

Standard gauging plate diameters range from 90% to 95% of the standard weight of the pipe’s inside diameter.”
