Hot dip galvanized seamless steel pipe with cold-galvanized seamless steel pipe
 
In order to improve the corrosion resistance of seamless steel tubes for general steel galvanized. Galvanized seamless steel hot galvanized seamless steel tubes and cold galvanized (electro-galvanized) seamless two, hot galvanized seamless steel galvanized thickness, with coating uniformity, strong adhesion, long life and other advantages .
Cold galvanized seamless steel plating, galvanizing small amounts only 10-50g/m2 of its own resistance to corrosion than hot dip galvanized pipe is a lot of difference. The regular hot dip galvanized seamless steel pipe manufacturer, in order to ensure quality, most of them do not use electro-galvanized (cold-plated).
Hot galvanized Seamless is first seamless steel pickling order to remove the iron oxide of the steel pipe surface after pickling, ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride, a mixed aqueous solution tank cleaning, and then fed to the hot-dip plating bath. Hot dip galvanized seamless steel pipe has a lot of advantages, so most of the uses are hot dip galvanized seamless steel pipe.
Gas, heating, air conditioning in buildings are hot dip galvanized seamless steel pipe, hot dip galvanized seamless steel pipe as water pipes, after a few years of use, the tube to produce large amounts of rust, yellow water outflow is not only pollution Ware and inclusion the forward not smooth inner wall of a breeding ground for bacteria, corrosion caused by high levels of heavy metals in water, seriously endangering the health of the human body.
The sixties and seventies, the international developed countries began to develop new pipe, hot dip galvanized seamless steel tubes and they are being disabled. Chinese Ministry of Construction and other four ministries issued a document clearly galvanized pipe disabled since 2000, the new district of the cold water pipe hot galvanized seamless steel has been rarely used, some residential hot water pipes hot galvanized pipe joints.
