Finding Proper Knapp Polly Pigs

Before you can choose the proper pig to clean your pipeline, it is important to understand the structure of your pipeline. Bends, valves, flow rates and internal pipe diameters are all keys to understanding what would be the most effective choice in a pipeline pig. Even though a Poly pig, for example, is extremely adaptable, you still need to know the key components of your pipeline to ensure the safety and effectiveness of your pigging program.

Whatever product is being moved, the pig is first placed into a launcher (either temporary or permanent). Pumps or compressors then move the product and pig to the next stop. As the pig moves through the line it will have to negotiate many things including valves, tees, wyes and any other potential obstructions. The Block Valve Station is a safety spot that allows the operator to separate a problem area, or identify problematic issues with a particular segment (these stations are usually located every 20 to 30 miles). If necessary, a Regulator Station can relieve some pressure before the product hits the Final Delivery Station, where the product is distributed to the consumer. Knapp Polly pigs are known for their ability to move through all of these areas and clean the pipeline.

Benefits of a Poly Pig

In addition to being flexible as well as an effective cleaning and batching pig, Polly Pigs are general cheaper than other types of pigs. Saving money and improving the product output is a combination that most companies would be very happy with. Using Knapp Polly Pigs is one step forward for keeping your pipeline structure clean and less susceptible to corrosion (which can lead to damaged equipment) and reduced flow. Keeping your pipeline in healthy condition reduces the likelihood of accidents, as well as the high costs related to repair.

Again, a Poly pig is an economical and effective tool for cleaning, batching, dewatering and decommissioning. With its ability to negotiate tight bends and squeeze through reductions, foam pigs are safe and effective tools for cleaning pipelines.
