Hot Dipped Q195 Q235 Q345 Seamless Round Galvanized Steel Pipe Description

Galvanized steel pipe is a welded steel pipe with a hot-dip or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their 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 pipelines in the petroleum industry, especially offshore oil fields, and oil heaters and condensation pipes for chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, trestle piles, and support pipes for mine tunnels, etc.

Pre-galvanized vs Hot-dip Galvanized Steel Pipe

Pre-galvanized steel pipe (also known as GI pipe) is made from continuous hot-dip galvanized steel strip wound and welded, and the galvanizing process takes place before the pipe is formed.

Hot-dip galvanized steel pipe are made from welded steel tubes with a black surface which are degreased, pickled, dipped, dried, and then impregnated with dissolved zinc for a period of time, with the galvanizing step taking place after the tubes are formed.
