Galvanized mild steel pipe is made of rust corrosion measures are not taken welding (welding furnaces, welding) pipe, seamless steel pipe or other metal clarinet, a certain process of hot-dip galvanizing, zinc coating to make it fit the outer coating, played long steel does not rust after processing. Today clarinet is generally welded steel pipe welding. Galvanized welded steel pipe used to transport require relatively clean medium, such as: water, clean air. Threaded pipe connection is a common way to connect, two hours at the factory welded pipe, pipe end with threaded and non- threaded.
In order to improve the corrosion resistance of steel tube, normally the carbon steel pipe will be galvanized. Galvanized steel is divided into hot galvanized and electro-galvanized two, thickness galvanized galvanized, electro-galvanized low cost, the surface is not very smooth. Increase the capacity of galvanized steel pipe corrosion and prolong life. Galvanized pipe is widely used, except for water, gas, oil, generally low- pressure fluid line pipe, also used oil heater oil industry in particular, marine oil wells pipes, pipelines, chemical coking equipment, condensing coolers, washing coal distillate oil exchange used tubes, as well as the bridge piles, mine tunnel support frame with a pipe.
Galvanized mild steel pipe for molten metal and iron matrix after a certain reaction with a layer of alloy layer, so that presents the effective combination between substrate and coating, and galvanized pipe can there are two ways to get, is a kind of hot dip galvanized pipe, and the other is electric galvanized, hot galvanized pipe production process is the first to effective pickling of steel tube, then you can, removing ferric oxide on the surface of the steel tube effectively will steel in ammonium chloride or zinc chloride solution after cleaning, after hot dip.
