Hydraulically activated pipeline pigging information
Hydraulically activated pipeline pigging (HAPP) is a pigging technology applied for pipeline cleaning. The basic principle is that a pressure drop is created over a by-passable pig held back against a pipeline's fluid flow. The pipeline fluid passing through the pigs cleaning head is accelerated by this pressure drop, forming strong cleaning jets. These jets are directed onto the inner wall in front of the pig, removing all kinds of deposits.
