The Hurricane Lead Pig (LP) acts as the lead pig of a double-pig train. It carries inhibitor or biocide treatment, allowing minimal by-pass. The inhibitor is contained between the LP and the Hurricane Filming Pig (FP). As the train moves through the line, the FP leaves a film of inhibitor on the pipe wall.
Designed to negotiate 1.5D or greater bends.
