Product Description

Galvanized steel pipe is a welded steel pipe with a hot-dip or electroplated zinc layer on the surface.
Hot-dip galvanizing pipe reacts molten metal with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to in a hot dip plating tank.
Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as line pipes for general low-pressure fluids such as water, gas, and oil, it is also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, as well as oil heaters and condenser pipes. It is also used in chemical coking equipment. Cooler pipes, coal distillation oil washing exchanger pipes, trestle pipes, mine tunnel support pipes, etc.
Hot-dip galvanized steel pipe grades: Q215A; Q215B; Q235A; Q235B.
