Product Details
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter still can be used temporarily by the country advocate.Sixty and seventy time, developed country begins to develop new type pipe material on the international, ban galvanized pipe in succession.The ministry of construction of China and other four ministries and commissions also made clear from 2000 onwards banned galvanized pipe as water supply pipe, the cold water pipe of the newly built community has rarely used galvanized pipe, some of the hot water pipe of the community is galvanized pipe.Hot dip galvanized steel pipe has a wide range of applications in fire, power and highway.
Galvanized pipe is electric galvanized, galvanized little, only 10-50g/m2, its own corrosion resistance than hot galvanized pipe is much different.Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electric galvanized (cold plating).Only those small, old equipment of small businesses use galvanizing, of course, their prices are relatively cheap.The Ministry of Construction has officially below, the elimination of backward technology of cold galvanized pipe, is not allowed to use cold galvanized pipe for water, gas pipe.The zinc layer of cold galvanized steel pipe is electroplated, and the zinc layer is independently stratified with the steel tube substrate.The zinc layer is relatively thin and is simply attached to the steel tube substrate, which is easy to fall off.Therefore, its corrosion resistance is poor.It is prohibited to use cold galvanized steel pipes as water supply pipes in new residential buildings.
