Shanxi walled galvanized elbow

Well most trusted manufacturers, Shanxi walled galvanized elbow, Bo Hang manufacturers. Manufacturers always adhere to the product for the pilot to quality as the basis, to serve as guarantee to the price as a lever, to mutual benefit for the center marketing philosophy has always been that customers create value of responsibility, continuous improvement and change. in a strong faith and perseverance to establish the reputation of our plant and corporate image. Main bends, bends, flanges, reducers , head caps and other pipe products have stock, we would like to domestic and foreign users to sincerely cooperate with us Hang Bo, for a better future! galvanized elbow is bend one elbow is plated surface a layer of zinc material to improve the corrosion resistance of the elbow. Galvanized elbow two hot galvanized and electro galvanized, hot dip galvanized thickness galvanized, electro-galvanized low cost, the surface is not very smooth. Galvanized cold plated tube bend points, hot dip tube, the former has been disabled, which is also the state to promote temporary use. Galvanized elbows Galvanized small amounts, only 10-50g / m2, its own corrosion resistance than galvanized pipe a lot of difference. Regular galvanized elbow manufacturer, quasi cold galvanized pipe for water, gas pipes. Cold galvanized Elbow: Elbow cold galvanized zinc coating is electroplated layer, the zinc layer and elbow individual layered substrate. Zinc layer is thin, simple zinc layer deposited on steel substrate easily. So the poor corrosion resistance. In the new house, prohibit the use of cold galvanized pipe elbows as to connect components. Galvanized elbow: galvanized elbow is the molten metal and the reaction of the iron matrix alloy layer, so that the substrate and coating combination of both. HDG is the first pickling elbow, elbow to remove surface oxide, after pickling, cleaning bath by mixing an aqueous solution of ammonium chloride or zinc chloride or ammonium chloride and zinc chloride aqueous solution, and then into the hot-dip plating bath. HDG has a uniform coating, strong adhesion, long life and other advantages. Galvanized elbows Uses: Galvanized elbow now use gas, that iron pipe heating with galvanized elbow, galvanized pipe fittings as elbow, use a few years, a large amount of rust inside the tube, not only pollute the water flowing yellow ware, and mixed with non-smooth inner wall of the breeding of bacteria, corrosion caused by heavy metal content of the water is too high, serious harm to human health. The sixties and seventies, developed countries have started to develop new pipe internationally and gradually disable the galvanized pipe and galvanized elbow. Chinese Ministry of Construction and other four ministries also issued a document explicitly disabled galvanized elbow from 2000 onwards, the new district is currently the cold water pipe has been rarely used galvanized pipe elbow connector, and some cells for hot water pipes are bent galvanized head connection. And galvanized elbow corresponding also cold galvanized elbow Cold elbow is used in electroplating galvanizing, cold galvanizing elbow galvanized relatively low, only 10-50g / m2, zinc layer and bend Head individual layered substrate. Zinc layer is thin, simple zinc layer attached to the outer elbow, relatively easily. So the poor corrosion resistance in some special occasions as prohibiting the use of cold galvanized elbow to the water connection components. But now a lot of small elbow manufacturer, using cold galvanized way to save costs.
