Hot dip galvanized tubings are welded with hot-dip or galvanized steel. Zinc plating can increase the corrosion resistance of steel pipes and prolong their service life. The matrix of the hot dip galvanized steel pipe can undergo complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant structure of a zinc-iron alloy layer. It makes the alloy layer integrate with the pure zinc layer and the steel pipe matrix, so it has strong corrosion resistance.
We have strictly controlled the manufacturing process so that the surface has a complete galvanized layer, and there are no uncoated black spots and bubbles.

Galvanized pipes are widely used, in addition to pipelines for general low-pressure fluids such as water, gas, oil, etc., and also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensation of chemical coking equipment, cooler, coal distillate oil exchanger pipe, and trestle pipe pile, support pipe for mine tunnel, etc.
Hot dip galvanized tubings are widely used in construction, machinery, coal, chemical, railway vehicles, automotive industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery and other manufacturing industries.
