Oil pipe pig is an indispensable tools in the maintenance and operation of pipelines, especially within the oil and gas sector. Operators deploy them within pipelines to execute various maintenance tasks, including cleaning, inspecting, and separating different batches of product. In this discussion, we specifically focus on the types, construction, and functions of pipeline pigs that primarily cleanse waxy crude oil residues from pipelines.

The Uni-directional Scraper Pig is a commonly used pig consisting of four cups and a steel frame. This pig is designed to effectively remove soft dirt and dust from pipelines. Its leather cups serve two important functions. Firstly, they provide excellent sealing performance, ensuring complete separation of liquids or gases at both ends of the pig. This creates a pressure difference that propels the pig forward. Secondly, the leather cups are capable of cleaning debris and dirt from the inner walls of the pipe.

A solid cast pig is an innovative, versatile, and efficient solution for pipeline cleaning and maintenance. These pigs are designed to combine the advantages of foam pigs, which offer flexibility and easy handling, and steel pigs, known for their ruggedness and excellent sealing capabilities

Pigs are supporting equipment for pipeline cleaning. Pigs for Pipeline Cleaning are driven by gas, liquid, or pipeline transmission medium. It can carry other auxiliary equipment to complete various complex pipeline operations. Without pigging technology, it is impossible to carry out pipeline construction and operation. Only pigs can accomplish a lot of work economically. Therefore, pipeline technology and pigging technology are inseparable.

The main body of Pipe Pigs is steel framework, equipped with 2-4 sealed cups or steel brush. Our products have been used long-term by the Daqing oil field and the Liaohe oil field with stable performance, reliable quality, has received coherent good comments from the customers.
