Brief Introduction of Welded Steel Pipes for Low Pressure Fluid Transportation
Low pressure fluid delivery with welded steel pipe (GB / T3092-1993) also known as general welded pipe, commonly known as the black tube. Is used to transport water, gas, air, oil and heating steam and other general low pressure fluid and other uses of welded steel pipe. Steel pipe wall thickness is divided into ordinary steel and thickened steel pipe; take the end into the form of non-threaded steel pipe (light pipe) and with a threaded steel pipe. The specification of the steel pipe is expressed by the nominal diameter (mm), and the nominal diameter is the approximate value of the inner diameter. Used in inches, such as 11/2 and so on. In addition to direct transmission of low pressure fluid welded steel pipe used to transport fluid, but also a large number of low-pressure fluid for the delivery of galvanized welded steel pipe of the original. Hebei Huayang Steel Pipe Co., Ltd.is theLow-pressure fluid welding pipe manufacturer in Northern China.
Low-pressure fluid welding pipe (GB / T3091-2001) This standard does replace the original GB / T3091-1993, GB / T14980-1994, GB / T3092-1993. For water, gas, air, heating steam and other low pressure fluid transport and other structures with the straight seam welded steel pipe. The welding available resistance welding or submerged arc welding. Resistance welded steel pipe is usually a length of 4 ~ 12m, submerged arc welded steel pipe length is usually 3 ~ 12m.Hebei Huayang Steel Pipe Co., Ltd.
