Galvanized pipe Knowledge Galvanized pipe is molten matrix metal and the reaction of the iron alloy layer , 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.

Cold galvanizing is galvanized, galvanized rarely, and only 10-50g/m2, its own hot dip galvanized pipe corrosion resistance than a lot of difference . Regular galvanized pipe manufacturers, in order to ensure quality , most do not use electro-galvanized ( cold plating ) .

Only those small, outdated equipment and small businesses using electro-galvanized , of course, their prices are relatively cheaper. Ministry of Construction has officially below , eliminate backward technology of cold galvanized pipe , galvanized pipe allowed for cold water , gas pipes . General are now using galvanized steel galvanized , carbon seamless steel pipe manufacturer china and with the use of electrical trunking and other cold galvanizing , color is quite different Cold galvanized plated --- just outside the wall , both inside and outside Redu --- plated . Galvanized steel is based on the re- welded steel hot dip galvanized ( ie zinc in zinc melting pot , and then immersed in liquid zinc steel some time out, and then cooled to dry ) .

While the steel pipe outer wall with a layer of zinc coating attached . galvanized pipe is generally used for low-pressure fluid ( ie, water, liquid gas ) delivery
