Product Description
Commodity name:
Galvanized steel pipe
Galvanized Round pipe
Manufacture Type:
ERW SAWL SAWH
Production process:
Black pieces of material hanging check-degreasing-washing-rinsing-pickling-fluxing agent impregnated hot air drying--hot-dip galvanized inside and outside blowing passivation and rinsing-cooling--unloading inspection, repair-typing logo-packaging and storage, transportation
Feature:
The molten metal is iron alloy layer and the substrate reaction, so that the substrate and coating combination of both. Galvanized pipe is first pickled, the steel surface in order to remove iron oxide, after pickling, cleaning tank by mixing an aqueous solution of ammonium chloride or zinc chloride and zinc chloride or ammonium chloride solution, and then into hot dip tank. Galvanized with coating uniformity, strong adhesion, long life and other advantages
Application:
Mainly used for conveying gas, heating
