Steel pipe for underground gas pipelines is coated using a process called fusion bonded epoxy coating. This involves preheating the pipe, applying an epoxy powder to it, and then heating it again to create a strong bond. This coating provides corrosion protection and helps to ensure the longevity and safety of the pipeline.
Steel pipe for underground gas pipelines is typically coated using a three-layer coating system. The first layer is a fusion-bonded epoxy (FBE) primer that provides corrosion protection. The second layer is an adhesive that helps bond the FBE to the pipe. Finally, the third layer is a polyethylene or polypropylene coating that acts as a protective outer layer. This coating process ensures the steel pipe is well-protected against corrosion and other potential damages in underground environments.
Steel pipe is coated for underground gas pipelines using a process called fusion bonded epoxy (FBE) coating. In this process, the steel pipe is preheated, and then an electrically charged epoxy powder is sprayed onto the heated pipe. The powder melts and fuses with the steel, creating a strong and durable coating that protects the pipe from corrosion and damage caused by underground elements.
