ASTM A106 Gr.B 48MM Welded Steel Pipe

     During the 11th Five-Year Plan period, oil and gas pipeline construction continued to develop rapidly, especially with the rapid growth of natural gas demand, natural gas pipeline became the focus of pipeline construction. At the end of the 11th Five-Year Plan period, China accelerated the distribution of oil and gas pipeline network, and the key oil and gas pipeline network covering the whole country has been initially completed. In the future, China's oil and gas supply security capacity will be further enhanced. Data show that by the end of 2010, the total length of oil and gas pipelines built in China was about 85,000 km, including 45,000 km of natural gas pipelines, 22,000 km of crude oil pipelines and 18,000 km of refined oil pipelines, forming a network of oil and gas pipelines spanning east and west, north and south, covering the whole country and connecting overseas.

     Welded Steel Pipe refers to the Steel Pipe with joints on the surface, which is welded after bending and deformation of steel strip or steel plate into circular, square and other shapes. The blank used for welding steel pipe is steel plate or strip steel. It can be divided into straight seam Welded Pipe and Spiral Welded Pipe. Generally, welded pipe is used to transport low-pressure fluid. It is made of q195a, q215a and Q235A steel. It can also be made of other mild steel that is easy to weld. Water pressure, bending, flattening and other tests shall be carried out for steel pipes, and there are certain requirements for surface quality. Generally, the delivery length is 4-10m, and fixed length (or double length) delivery is often required. The specification of welded pipe is expressed in nominal diameter (mm or inch). The nominal diameter is different from the actual. Welded pipe can be divided into ordinary steel pipe and thickened steel pipe according to the specified wall thickness. According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blowing welded pipe, wire sleeve, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welding thin-wall pipe, electric welding special-shaped pipe and spiral welded pipe.
