Product Description
Galvanized steel pipe/tube is an alloy of iron and carbon. It is rolled into a tube - usually round, square or rectangular - and then coated with zinc. Steel pipes are usually galvanized in one of two ways. It can be hot-dip galvanized, a thick protective coating can be formed by molten zinc, or a thinner layer of zinc can be attached to the steel by electroplating through the current zinc solution.Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life.
Welded steel pipe with hot-dip or electro galvanized coating on the surface of galvanized steel pipe. 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 water transmission, gas, oil and other general low-pressure fluids, they are also used as oil well pipes and oil transmission pipes in the petroleum industry, especially in offshore oil fields, pipes for oil heaters, condensing coolers and coal distillation oil washing exchangers of chemical coking equipment, trestle pipe piles and support frames of mine tunnels.

Galvanized steel pipes have a wide range of uses. In addition to being used as pipelines for low-pressure fluids such as water, gas, and oil, it is also used in the petroleum industry, especially oil well pipelines, oil pipes and petroleum heaters in offshore oil fields, and used in chemical coking equipment. Condensation cooler, coal distillation wash oil exchanger pipeline, as well as mine pipe piles, mine tunnel support frame pipelines,Urban/civilian construction pipes, mechanical structure pipes, agricultural equipment pipes, water and gas pipes, greenhouse pipes, scaffolding pipes, building materials pipes, furniture pipes, low pressure fluid pipes, oil pipes, etc. Also, galvanized steel pipes are widely used in construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, greenhouse construction and other manufacturing industries.
