When municipal wastewater force mains or other industrial piping systems suffer from reduced flow, progressive poly pigging (Pipe Pigging) may be the best choice to rectify the situation and restore maximal flow. But, just what is Poly Pigging anyway?
Any professionally designed piping system will have been engineered with certain flow rates (Gallons per minute), velocities (Feet per second) and pressure (PSI). During the life of the system, low flow velocities or high concentrations of FOG (fat, oil, grease) and sediment will lead to material build up on the inside surfaces of the pipes. This leads to reduced flow, higher energy cost and maintenance for the pumps, and possibly system failure that could include a nasty spill.
Poly pigging (Often written as "Polly Pigging") is the use of a polyurethane or other material slug, known as a pig, to clean the inside of a pipe. It is propelled through the system by the same force that carries the system's product, or pulled through the system using a cable. It can often be done with little to no interruption of service. Progressive poly pigging (polly pigging) is the use of various sizes and densities of pig, passed in sequence, through a pipe system, inspecting the pig and the product until the pipes are at their optimum clean. On each pass, the pig exits the system into a "pig catcher" and the debris is collected for disposal.
Poly Pigging can be used alone or in conjunction with other cleaning methods such as high pressure water jetting to ensure your pipe system achieves and maintains its optimal flow.
