Welded steel pipe has hot dip and the electro galvanized coating on the surface of galvanized steel pipe. Galvanized steel pipe can increase the corrosion resistance of steel pipe and prolong its service life.
Galvanized steel pipes uses are wide, not only as pipelines for water delivery, gas, oil and other general low-pressure fluids, but also for oil well pipes and oil pipelines in petroleum industry, especially in offshore oil fields, oil heaters, condensing coolers, coal distillate wash oil exchangers for chemical coking equipment, trestle pipe piles. Galvanized steel pipes can also support frame pipes for mine tunnels, etc.
Because galvanized steel pipe is galvanized on the steel pipe. Galvanized square pipe is widely used in mechanical manufacturing, curtain wall, construction, shipbuilding, steel construction project, steel structure engineering, solar power generation support, electrical engineering, agricultural and chemical machinery, power plant, automobile chassis, airport, etc.
Advantages of galvanized steel pipe
1. Hot dip galvanizing has uniform coating, strong adhesion and long service life;
2. Strong corrosion resistance;
Galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, exploration machinery and other manufacturing industries.
