Premium Galvanized Steel Pipe for Reliable Water Delivery Systems
Premium Galvanized Steel Pipe for Reliable Water Delivery Systems
Galvanized steel pipe is a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles, supporting frames for mine tunnels, etc.

1.Black square&rectanhgular steel pipe:ERW steel tube
2.Pre-galvanized square&rectangular steel pipe: Pre-galvanized square/rectangular tube is made of hot dipped galvanized steel strip directly.
3.Hot dipped galvanizedsquare&rectangular steel pipe : Hot dipped galvanized square/rectangular tube owns thicker zinc coating than pre-galvanized square/rectangular tube. Black tubes will be dipped into zinc pool for galvanizing.
4.Electro galvanized square&rectangular steel pipe : The technology of electro galvanized square/rectangular tube is similar to hot dipped galvanized tube, but the thickness of zinc coating is less than hot dipped galvanized tube.
5.Painted square&rectangular steel pipe:Painted square/rectangular to remove the rust and clean the oil first and then paint the required color paint.
