Galvanized Steel Pipe
Galvanized Steel Pipe Product Description There are two types of galvanized steel pipes, one is galvanized strip steel pipe, also called pre-galvanized steel pip e, and the other is hot-dip galvanized steel pipe. A dvantages of galvanized steel pipe including : Prevent corrosion and rust Increase structural life Overall enhanced reliability affordable protection easy to check less maintenance strong toughness Easier to maintain than standard painted pipes Protected by advanced ASTM standardization The pre-galvanized steel pipe is a kind of ERW steel pipe . The processing process is the same as that of the ERW steel pipe, except that the raw material is galvanized steel coil. The weld will be repaired with zinc again, so there is no obvious weld on the surface, which is more beautiful. It is not only the zinc layer that determines the life of the pre-galvanized steel pipe, but also the passivation solution. After forming, soaking in high-quality passivation solution can extend the life ...
