Hot dip galvanized pipe

The molten metal is reacted with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. Most of the northern processes use galvanized strips to directly coil the zinc.

Cold galvanized pipe

Cold galvanizing is electrogalvanizing. The amount of galvanizing is very small, only 10-50g/m2, and its corrosion resistance is much worse than that of hot-dip galvanized pipes. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use electro-galvanizing (cold plating). Only small companies with small equipment and old equipment use electro-galvanized steel, of course, their prices are relatively cheaper. In newly built houses, the use of cold-galvanized steel pipes as water supply pipes is prohibited.

Galvanized Steel Pipe Production Line for Special Demands

For galvanized steel pipe production lines have special requirements, especially in a production environment this, a good environment can help us better production, improve production quality and production efficiency, particularly galvanized steel that needs a stable environment products even more so.

First, Ensure that the production line for delicate work processes, equipment, heating, ventilation, drainage, etc., all work must center around quality galvanized steel to expand, as long as the quality of the galvanized steel to ensure good, all other factors we can be achieved.
