Introduction to Liner Pipe
Liner pipes are specialized pipes designed to provide a protective inner layer within a larger pipeline system. They play a crucial role in various industries, such as oil and gas, chemical, and water treatment. The main functions of liner pipes include corrosion resistance, abrasion resistance, and the ability to maintain the integrity of the fluid being transported. By using liner pipes, the service life of the overall pipeline can be significantly extended, and the risk of leakage and contamination can be reduced.
