Hebei Chengyuan Pipe Industry Group Co., Ltd
Welded steel pipe with hot dip or galvanized layer on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipe and prolong its service life. Galvanized pipes are widely used in petroleum industry, especially in offshore oil fields, oil wells, pipelines, oil heaters, condensation coolers, coal distillation oil wash exchangers, trestle pipe piles and support pipes for mine tunnels.
Instructions
It is often said that galvanized pipe, the kind of iron pipe used for gas and heating of galvanized pipe is also galvanized pipe. Galvanized pipe is used as water pipe. After several years of use, a large amount of rust scale is produced in the pipe. The yellow water not only pollutes the sanitary ware, but also contains bacteria that grow on the non-smooth inner wall. The rust causes the excessive content of heavy metals in the water, which seriously endangers human health.
Rust removing method
1. First, the surface of steel is cleaned by solvent, and the organic matter on the surface is removed.
2. Then use tools to remove rust (steel brush), loose or inclined scale, rust, welding slag, etc.
3. Use pickling method.
Galvanizing is divided into hot and cold plating, hot plating is not easy to rust, cold plating is easy to rust.
