Just What Is Pipe Pigging Anyway?

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.

Tampa Water Jet Pipe Cleaning

I've written about Water Jet Cleaning before, but It's time to revisit the topic.

The last time I wrote about this, I started out with a mention that poly pigs are the first choice of many Piping Systems Engineers. My client, Professional Piping Services, Inc., provides that service for Tampa Florida as well.

But, there may be times that a poly pig, especially in HDPE pipes, might pose a risk of damage to the pipe. There are soft pigs that mitigate or eliminate that risk, but when there is sediment that might grind between the pig and the inside of the pipe, water jetting may be the preferred method.

High pressure water jet pipe cleaning works to clear debris from any size pipe. Jetting is effective against tree roots, cooking grease, automotive grease, lime / hard water buildup, sewage sludge and more that might be found in your Tampa Piping System.

Shutdowns cost money! Backups cause property damage! Preventative maintenance is key! When debris causes the effective inside diameter of the pipe to get smaller and smaller, reduced flow and higher energy costs are sure to follow, along with costly repairs to overworked pumps.


The pipe cleaning professionals at  Professional Piping Services, Inc will help you determine if poly pigginh, water jetting, or a regiment of both, will most efficiently get your pipes back to full capacity. They have the right equipment such as water pumps, jets, poly pigs and water tanks, as well as training and experience to properly care for your Tampa Industrial Piping.
