What is a Lining steel pipe?

Lined steel pipes are steel pipes that have been coated or lined with another metal or material on the inner surface to enhance corrosion resistance, wear resistance, and heat resistance. These pipes are primarily used in piping systems that transport corrosive fluids, and the inner lining often consists of stainless steel, alloys, or ceramics. Lined steel pipes have a longer lifespan compared to regular steel pipes and reduce maintenance costs, making them widely used in harsh environments such as chemical plants, oil refineries, wastewater treatment facilities, and power plants. The steel pipe retains its strength and pressure resistance, while the lining protects the internal surface from contact with the fluid. Lined steel pipes effectively solve corrosion and wear issues and maintain stable performance over long periods.

Application of Lining steel pipe

１．Chemical Plants: Lined steel pipes are used to transport corrosive chemicals such as acids and solvents safely, preventing corrosion from damaging the pipes.
２．Oil Refineries: These pipes are used in refining processes where high temperatures and corrosive substances are common, ensuring long-term durability and reducing maintenance.
３．Wastewater Treatment Facilities: Lined steel pipes are essential in carrying wastewater and effluents, where the risk of corrosion and wear from chemicals and abrasive particles is high.
