Q355B Hot Dipped Galvanized Pipe

 Product Description

Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Cold galvanized steel pipes have been banned, and the latter has also been advocated by the state for temporary use. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes, and gradually banned galvanized pipes. Hot dip galvanized steel pipes are widely used in fire protection, electric power, and highways.

Production steps

The process flow is as follows: black pipe - alkali washing - water washing - acid washing - clear water rinsing - soaking auxiliaries - drying - hot dip Galvanizing - external blowing - internal blowing - air cooling - water cooling - passivation - water rinsing - inspection - weighing - warehousing.

Product Application

Galvanized Steel Pipe is a Welded Steel Pipe with a hot-dip or electrical galvanized coating on its surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used, in addition to being used as pipeline pipes for transporting general low pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil delivery pipes in the petroleum industry, especially in offshore oilfields, as well as pipes for oil heaters, condensate coolers, and oil exchangers for coal distillation and washing equipment in chemical coking equipment, as well as for trestle pipe piles, and support frames for mining tunnels.

Hot dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemical engineering, electric power, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery, and greenhouse construction.
