The Application of Galvanized Steel Pipe
In order to improve the corrosion resistance of steel pipe, the general steel pipe galvanized. Galvanized steel sub-hot galvanized and galvanized two kinds of hot galvanized galvanized layer thickness, low cost of electro-galvanized, the surface is not very smooth. Oxygen Oxygen Welded Pipe: used for steel-making oxygen blowing pipe, the general use of small diameter welded steel pipe, specifications from 3 / 8-2 inch eight. With 08,10,15,20 or 195-Q235 made of steel, in order to prevent corrosion, and some to be effective aluminizing treatment.
Most of the old house is galvanized pipe is used, and now the kind of gas heating pipe is galvanized pipe, galvanized pipe as a water pipe, use a few years later, the tube produces a lot of rust, yellow water outflow not only Pollution, sanitary ware, but also mixed with non-smooth wall breeding bacteria, corrosion caused by heavy metal content in the water is too high, serious harm to human health. The sixties and seventies, the international developed countries began to develop new pipe, and gradually banned galvanized pipe. China’s Ministry of Construction and other four ministries also issued a clear from the 2000 ban galvanized pipe, the new district of the cold water pipe has been rarely used galvanized pipe, and some of the district’s hot water pipe is galvanized pipe.
