ASTM S275jr 25mm Galvanised Steel Round Tube Pipe

 

Galvanized Pipe is divided into hot galvanized and cold galvanized two kinds. The zinc layer is an electroplating layer, and the zinc layer is independently layered with the Steel Pipe matrix. The zinc layer is thin, and the zinc layer is simply attached to the steel tube matrix and easy to fall off. Therefore, its corrosion resistance is poor. In new residential buildings, it is prohibited to use cold galvanized steel pipes as water supply pipes.
The matrix of hot dip Galvanized Steel Pipe and the molten bath undergo complex physical and chemical reactions to form a tight zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, its corrosion resistance is strong. Hot-dip galvanizing has a longer life than cold galvanizing.
