Manufacturer supply galvanized steel pipes Typically, the process of the surface preparation of galvanized iron pipes operates as follows:
Firstly, the steel is cleansed with the use of a caustic solution - a corrosive substance in where it will completely remove all oil, grease, dirt, and excess pain.
Manufacturer supply galvanized steel pipes After the caustic solution is rinsed off, the iron pipe is then pickled. Pickling is a metal surface treatment that is used to eliminate stains, impurities, contaminants, rust, or scale from ferrous metals. The iron pipe is pickled in an acidic solution to get rid of the mill scale or also known as the flaky surface of the hot-rolled steel.After the pickling solution is rinsed off, the iron pipe will not proceed to fluxing. Commonly, zinc ammonium chloride is what's used to the base metal to suppress oxidation of the cleaned surface.
