Q: What is the difference between internal coating and external lining of steel pipes?: Steel pipes can be protected from corrosion and damage through two different methods: internal coating and external lining. When it comes to internal coating, a protective layer or coating is applied to the inner surface of the steel pipe. This is done to prevent corrosion or damage caused by the fluid or substance being transported through the pipe. Common materials used for the coating include epoxy, polyurethane, or polyethylene. These materials create a barrier between the pipe and the transported material, thus extending the pipe's lifespan and preserving the quality of the transported material. On the other hand, external lining involves applying a protective layer or lining to the outer surface of the steel pipe. The purpose of this is to shield the pipe from external elements like soil, moisture, chemicals, and physical damage. Materials such as polyethylene, polypropylene, or fusion-bonded epoxy are typically used for the external lining. By acting as a barrier, the lining prevents corrosive substances from coming into contact with the pipe and causing harm. Additionally, it helps maintain the pipe's structural integrity and prevents the formation of leaks or cracks. To summarize, the main distinction between internal coating and external lining of steel pipes lies in where the protective layer is applied. Internal coating focuses on the inner surface of the pipe, while external lining concentrates on the outer surface. While both methods aim to safeguard the pipe from corrosion and damage, they address different aspects of pipe protection.
