The Product Displacement Pig' (PDP) design offers the ability of batching and displacement of products in
lines with 1.5-degree bends and standard full-branch tees. With the pig's multiple sealing discs, cross-contamination and bypass are no longer a problem. The sealing distance allows for
spanning of full-branch tees without losing seal. Its tapered shaft and bumper noses on each end allow the pig to negotiate sharp radius bends.
Applications for this system include loading
and unloading lines, processing plants, packaging areas, raw material handling and storage, blending areas, and transportation in the oil & gas, food & beverage, chemical & petrochemical,
cosmetic & pharmaceutical, and ink & paint industries.
The following diagram illustrates the utilization of the PDP Pigging System in a typical plant application.
