What is a Steel Pig?
Also known as a mandrel pig, steel body pigs are utility pipeline products used for cleaning and sealing in a number of different industries. Steel pigs have steel mandrel bodies and mandrels on the outside diameter, and are equipped with special brushes, polymer discs, or cups.
Steel pigs effectively clean the inner walls inside pipelines that transport fluids or liquid products.
Over time, debris collects inside, leading to clogs, corrosion and a multitude of other pipeline problems. Mandrel or steel body pigs can also be used for sequentially transporting and batching multiple products through a pipeline. Learn more about the applications for scraper pigs here.

The discs and cups create a seal between different products in a pipeline, while at the same time displacing residual water or product (liquid displacement) in the pipeline. Because steel pigs are bi-directional, they can travel either up or down a pipeline for general cleaning or removal of paraffin or black powder.
Some steel body pigs are equipped with gauge plates for use in gauging pipelines. Specially designed to ensure longevity, steel mandrels are extremely durable. When you need to replace components, it would usually be softer brushes and cups.
