ST47 Alloy Galvanized Steel Pipe 1 2 1/2 1/4 Inch Galvanized Tube
For Automobile Industry
Hot dip galvanized pipe is to make molten metal and iron matrix
reaction to produce an alloy layer, so that the matrix and coating
are combined. Hot dip galvanized steel pipe is first pickling, in
order to remove iron oxide on the surface of the steel pipe, after
pickling, through ammonium chloride or zinc chloride aqueous
solution or ammonium chloride and zinc chloride mixed aqueous
solution tank for cleaning, and then into the hot dip plating tank.
Hot dip galvanizing has the advantages of uniform coating, strong
adhesion and long service life. Hot dip galvanized steel tube
matrix and molten bath have complex physical and chemical
reactions, forming corrosion resistant structure of tight zinc-iron
alloy layer. The alloy layer is integrated with pure zinc layer and
steel tube matrix, so it has strong corrosion resistance.
Cold galvanized pipe is electric galvanized, galvanized amount is
very little, only 10-50g/m2, its own corrosion resistance is much
different than hot galvanized pipe. Regular galvanized pipe
manufacturers, in order to ensure quality, most do not use
galvanized (cold plating). Only those small enterprises with
obsolete equipment use electrogalvanizing, of course, their price
is relatively cheaper. The Ministry of Construction has officially
below, the elimination of cold galvanized pipe technology behind,
not allowed to use cold galvanized pipe for water, gas pipe. The
galvanized layer of cold galvanized steel pipe is an electric
coating, and the zinc layer is independently layered with the steel
pipe matrix. The zinc layer is thin, and the zinc layer is simply
attached to the steel tube matrix and easy to fall off. Therefore,
its corrosion resistance is poor. In new residential buildings, it
is forbidden to use cold galvanized steel pipes as water supply
pipes.
