Pipe production process is simple, high efficiency, low cost, faster development. Wide range of uses, different specifications, according to the form of the weld in general we can divide it into spiral welded pipe, lean management, the different types of welded pipe, etc., which production processes, material selection is not the same, so the scope is not the same . Today Linyi pipe major manufacturers to introduce you to spiral welded knowledge. 1, the general low pressure liquid delivery spiral submerged arc welded seam scale is as hot rolled strip coil tube, often warm spiral shape, using double-sided automatic submerged arc welding or welding into the legal system for water, gas, air and steam low pressure liquid delivery SAW pipe. 2, low pressure liquid delivery spiral welded steel pipe, also known as general welded pipe, commonly known as the clarinet. Welded steel pipe for conveying water, gas, air, oil and heating steam and other general low pressure fluid and other uses. 3, the low pressure fluid galvanized welded steel pipe, also known as galvanized welded steel pipe, commonly known as white tube. Is used for conveying water, gas, oil and air heating steam, heated and other general low pressure fluid or other uses of hot-dip galvanized welded (furnace brazed or welded) steel pipe. Pipe wall thickness is divided into ordinary galvanized steel pick and thicker galvanized steel; take over end into the form of a threaded galvanized steel pipe without threaded galvanized steel and band. Steel pipe with a nominal diameter specifications indicated nominal diameter is the diameter of the approximation. 4, pressurized fluid delivery SAW spiral scale is as hot rolled strip coil tube, often warm spiral shape, with double-sided submerged arc welding method for spiral seam steel pressurized fluid delivery. Strong pressure steel, welding performance is good, via a variety of rigorous scientific inspection and testing, the use of safe and reliable. Pipe diameter, high transmission efficiency, and can save the laying of pipeline investments. Mainly used for oil pipelines, natural gas. Source: http: //www.lygccj.com
