Galvanized steel pipe with hot dip galvanized layer of welded steel pipe surface can increase the corrosion resistance of steel pipe and prolong its service life. Galvanized pipe's usage is very wide, in addition to a general low pressure fluid such as water, gas, oil line pipe, also used as oil industry, especially the ocean oil field oil well pipe, oil pipe, chemical coking equipment of oil heater, the condensing, exchange of coal distillation wash oil cooler for tube, and trestle pile, mining tunnel supporting frame tube , etc.
Application Urban construction pipe, machine structure pipe, water and gas pipe,green house pipe, scaffolding pipe, building material tube, furniture tube, low pressure fluil pipe, oil pipe etc.
