Classification of galvanized Steel pipe:

Galvanized steel pipes are divided into bloodless galvanized steel pipes and hot-dip galvanized metallic pipes.The recent-dip galvanized pipe reacts the molten metal with the iron substrate to provide an alloy layer, so that the substrate and the coating are mixed. hot-dip galvanizing is to pickle the metallic pipe first. A good way to cast off the iron oxide at the ground of the metallic pipe, after pickling, it's far cleaned with the aid of ammonium chloride or zinc chloride aqueous solution or a combined aqueous answer of ammonium chloride and zinc chloride, after which sent to warm-dip coating tank. Warm-dip galvanizing has the blessings of uniform coating, robust adhesion and lengthy issuer lifestyles. The recent-dip galvanized metal pipe substrate undergoes complex physical and chemical reactions with the molten plating answer to structure a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is built-in with the natural zinc layer and the steel pipe substrate, so it has robust corrosion resistance.

Hot Dip Galvanized Steel Pipe

Bloodless-dip galvanized pipe is electro-galvanized, the amount of galvanizing may be very small, and its corrosion resistance is lots worse than that of hot-dip galvanized pipe. The galvanized layer of cold-dip galvanized metallic pipe is an electroplated layer, and the zinc layer is independently layered with the metal pipe substrate. Zinc is noticeably thin, and the zinc layer is with out problems linked to the metallic pipe substrate and is easy to fall off.

Consequently, its corrosion resistance is poor. In newly constructed houses, it's far forbidden to use cold-galvanized metal pipes as water furnish pipes.

Weight issue

The mechanical homes of metal are vital signs to ensure the end-use overall performance (mechanical residences) of metallic, which relies upon at the chemical composition and warmth remedy device of metallic. In metallic pipe standards, tensile houses (tensile power, yield electricity or yield point, elongation), hardness, longevity, and excessive and low temperature houses required through clients are special in accordance to precise use requirements.Category of galvanized steel pipe:
