Pigging is a concept in pipeline maintenance that involves the use of devices known as pigs, which clean pipelines and are capable of checking pipeline condition. This process is done without necessarily interfering with the flow of product in the pipe. Pigging is used in a number of different industries including oil & gas, lube oil, chemical plants and hygienic applications such as pharmaceutica
l or food. Selecting the right pig for a particular application requires extensive experience, something.is the most basic type of pig and its purpose is to remove any debris or liquid from the pipeline.. Inline stocks a huge inventory of different types of foam pig. Bare Foam and coated pigs are used for general cleaning, batching and proving, especially after construction as they are extremely flexible; The Power Brush Pig® has brushes to remove stubborn material, typically corrosion deposits; The Foam Disc Pig is a flexible pig designed by Inline for the very efficient removal of liquids such as hydrotest water. Available in a large size range, foam pigs play an important role in the safe cleaning and proving of pipelines.usually consist of a metal body to which replaceable discs, cups and/or scraper brushes or gauging plates are bolted. Disc pigs such as the BD6 are ideal for liquids and wax removal. Cups are added where extra sealing or wear resistance is required and are particularly effective for accommodating pipes that are out of round. Inline’s ISTE pig consists of brushes, cups and discs and is very efficient at cleaning, liquids removal and especially the removal of black powder. Specially designed pencil brushes on Inline’s Pit Cleaning Pig® are designed to clean corrosion pitting and black powder removal. URETHANE PIGS
a more flexible pig such as the Uni-Cup Pig® is designed for cleaning, wax removal and liquids displacement, but are manufactured as a one-piece construction. All of Inline’s urethane products can be manufactured using Maxithane®, Inline’s proprietary long lasting, wear resistant formulation of polyurethane.
