Hot Dipped Galvanized Steel Pipe, in order to improve the corrosion resistance of steel pipe, the general steel pipe galvanized.Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
Nominal wall thickness:2.0, 2.5, 2.8, 3.2, 3.5, 3.8, 4.0, 4.5mm;
Specification:dn15-200mm,
Length: 6 meters, which can be customized according to the requirements of the buyer.
Yield point (Reh) : 195-235 (Mpa)
Tensile strength Rm: 375-420 (Mpa)
Elongation: 35-25 (%)
Galvanized steel pipe has the following production steps:
Black parts inspection → hangings → degreasing → rinsing → pickling → cleaning → dip aid → hot air drying → hot dip galvanized → cooling → passivation and rinsing → unloading → inspection, dressing → packaging and storage, transportation.

Application
Hot dip galvanized steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry,Road, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.A welded steel pipe having a hot dip or electric galvanized surface.Galvanized steel pipe can increase the corrosion resistance,Extend service life.Galvanized pipe is widely used in addition to water, gas, oil and other general low pressure fluid pipe
In addition, it is also used in oil industry, especially in offshore oil field, oil pipe and chemical coking equipment
Heater, condensing cooler, coal distilling oil exchanger pipe, trestle pipe pile, mine tunnel support frame Tube, etc.
