What Is The Function Of Galvanized Fire Pipe?

Galvanized fire pipes, also known as galvanized steel pipes, are divided into hot galvanizing and electronic galvanizing. Hot galvanizing has a thick galvanized layer and has the advantages of uniform coating, strong adhesion, and long service life. Electronic galvanizing is low in cost, the surface is not very smooth, and its corrosion resistance is much worse than that of galvanized pipes. Hot-dip galvanized pipe is to make molten metal react with an iron matrix to produce an alloy layer, thus combining matrix and plating layer. Hot galvanizing is to pickle the steel pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, the steel pipe is washed in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride and then sent into a hot-dip plating tank. Hot galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Most of the processes in the north adopt a direct coil zinc filling process with a galvanized strip. Cold galvanized pipes are electronic-galvanized. The amount of galvanization is very small, only 10-50g/m2. Its corrosion resistance is much different from that of hot galvanized pipes. Hot-dip galvanized steel pipes have hot dip plated welded steel pipes on their surfaces. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. Galvanized pipes have good corrosion resistance, acid and alkali resistance, and generally, do not need surface treatment. So galvanized pipes are used. Galvanized pipes can be welded with carbon dioxide gas shielded welding, and then the welding will not be coated with primer and anticorrosive paint for three times, so as to ensure its reliability and durability.

Galvanized steel construction pipes are made up of galvanized steel tubes, which are unpacked, flattened, crimped and welded to form round tubes, which are then rolled into square tubes and then cut to the required length. Generally, 50 square tubes per package are mostly of large specifications in the spot, ranging from 10*10*0.8-1.5~~500*500*10-25. The square tubes are divided into structural square tubes, decorative square tubes, building square tubes, mechanical square tubes, etc. according to their uses. Square tube is a kind of appellation for square tube, that is, steel tube with equal side and length. It is made by rolling strip steel through technological treatment. Replacing and drawing square tubes: strip steel is usually unpacked, flattened, crimped and welded to form round tubes, which are then rolled into square tubes and then cut to the required length.
