Galvanized pipe galvanized pipe cleaner production unique electro-galvanized iron alloy kraft process, that were produced between trough and trough piercing straight through and out without any solution or overflow. Steps in the production by the circulation system components, each slot solution that alkali solution, plating solution, the light and the passivation solution, they just loop back to the outside of the system with no leakage or discharge galvanized pipe manufacturers, production lines located only 5 cleaning tank, using recycled back with regular emissions, especially after passivation without cleaning without wastewater production process. Guangdong days steel bridge Limited (: days ducts), is China's leading large southern area nursing care line cable manufacturer, has 10 years of experience in the development and production of galvanized pipe, tank and fittings in the field, production capacity, output and market share position, according to the Southern Region three indicators in the forefront. Days ducts is China's leading large southern district nursing care line cable manufacturer, has 10 years of experience in the development and production of 3.8 GB pipe galvanized pipe galvanized pipe, tank and accessories areas, capacity, output and market share three indicators bit rate according to the forefront of the Southern Region. Galvanized square tube with hot galvanized square tubes and galvanized square tube into two categories. Galvanized square tubes have wet, dry, lead, zinc, oxidation-reduction method. The main difference between the different methods of hot-dip galvanized steel pickling after cleaning galvanized pipe, the method used to improve the activation of galvanized pipe surface quality. Production is now mainly used dry and redox method, which is characterized in Table. Galvanized zinc coating surface is very smooth and dense, uniform organization; has good mechanical properties and corrosion resistance; zinc consumption 60% to 75% lower than the hot-dip galvanizing. Galvanized technically have some complexity, but for single-sided coating, coating thickness and external surfaces of different double-sided coating, as well as thin-walled tube galvanized mused must use this method. 3.6 GB pipe hot galvanized pipe | days ducts (certified) | galvanized pipe by pipe bridge, Ltd.
