The use and classification of cleaning pigs
EMT Piping Techonology Co., Ltd.
Provide pigging products for oil and gas pipeline.
These pipelines have been in operation for decades due to the ubiquity of piping systems for the safe transport of various liquids and gases over long distances.
The first task is to remove all kinds of deposits in the pipeline that hinder the transportation of liquid or gas. In addition, it is necessary to remove rust and garbage from the pipes that enter or remain on the construction site for various reasons.
Regular cleaning of the pipes makes economic sense because it can greatly reduce the shipping costs of the product. Cleaning is performed using a variety of pigs that pass through the pipeline with the flow of liquid or gas. Pig accessories (polyurethane discs, cuffs, brushes, magnets, etc.) remove deposits from the pipe walls and bring them to the pig receiver.
The cleaning pig should be designed to make it safe (no downtime and jamming) through the entire length of the pipeline from the pig launcher to the pig receiver. Since each pipeline has its design features and construction flaws, different pigs can be used.
Experts in pipeline operators, they have different preferences. EMT's engineers put great effort into providing pig designs that can be customized to customer requirements while maintaining equipment reliability, low cost, and short manufacturing times.
EMT mainly manufactures Disc Pig, Cup Pig, Foam Pig and Solid Cast Pig:
Foam pig is an economical and effective pig for several applications. EMT Polyurethane Foam pigs for pipe cleaning are used on all types of pipes (steel, polyethylene, cast iron, etc.). Its adaptive performance meets the pipeline with a small turning radius or even a right-angle bend and major diameter reductions.?The foam pig can be?used for cleaning, isolation and?drying?.

It is applied to pigging before production, cleaning the stones, wood bars and other matters left in the pipeline. EMT pigs are specially designed for cleaning the inner surfaces of pipes.
The EMT CUPS range of cleaning pigs are very flexible devices that can be easily adapted to specific tasks, the polyurethane discs with extremely high abrasion resistance allow cleaning in almost any environment (oil, gas, petroleum products, sea water).In order to control the movement of the pig through the pipeline, the pig can be equipped with a transmission.
EMT customized Conical cup solid cast pig, integrally formed, made of polyurethane.
The solid cast pig is uaually applied to the pipelines containing the medium of water, gas or oil. The pressure difference between the front and the back of the pig pushes the pig forward so that the pipeline is cleaned by the pig.
EMT solid cast pig has the features of good looking appearance, strong wear resistance performance, etc.
