1. The surface of the steel pipe is treated with anti-embroidery, which is more durable, not more than too fast oxidation, and will not form white rust on the steel pipe;2. Fully protect the steel pipe. After heating, every part of the steel pipe is plated with zinc, and the concave and convex parts

Stainless steel fluid pipes are used to transport fluid substances and are used in food, pressure vessels, industrial transportation, and other industries. The pipelines used to transport fluids have very high requirements for the process. The most critical points are:1. Requirements for pipe materi

The coating methods of large-diameter water-conveying plastic-coated steel pipe plastic-coating equipment are divided into two categories: simultaneous internal coating and external coating, and separate internal coating and external coating.Process coating methods are also divided into two categori

1. Compression type: Insert the pipe into the nozzle of the pipe fitting, fasten it with a nut, and compress the casing of the nozzle through the sealing ring with a screw force, which plays a sealing role and completes the connection of the pipe.2. Welding type: The end of the pipe is beveled, and
