Galvanized Pipe Utilization

In order to improve the corrosion resistance of the steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot-dip galvanizing and electro-galvanizing. The thickness of hot-dip galvanized galvanized layer is low, the cost of galvanizing is low, and the surface is not very smooth. Oxygen blowing pipe: used as oxygen-blowing steel pipe, generally used small-diameter welded steel pipe, specifications from 8/8 inch 8/8. With the 08, 10, 15, 20 or 195-Q235 made of steel, in order to prevent corrosion, and some effective aluminizing treatment.

Most of the old houses use galvanized pipes. Now the kind of iron pipes used for gas and heating are also galvanized pipes. The galvanized pipes are used as pipes. After a few years of use, a lot of rust is generated inside the pipes. The outflow of yellow water is not only Contaminated sanitary ware, but also mixed with bacteria that grow on rough surfaces, rust causes excessive levels of heavy metals in the water, which seriously endangers human health. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and banned galvanized pipes one after another. China's Ministry of Construction and other four ministries also issued a document stating that galvanized pipes have been banned since 2000. At present, galvanized pipes have rarely been used for cold water pipes in new communities, and hot water pipes in some communities use galvanized pipes.
