ASTM API 5L Welded round steel pipe

       The Outline of the 12th Five-Year Plan clearly states that the second phase of the China-Kazakhstan crude oil Pipeline, the domestic section of the China-Myanmar oil and gas pipeline, the second phase of the Central Asian gas pipeline, and the third and fourth lines of the west-east gas pipeline will be built, and supporting branch lines and urban pipe networks will be built. By 2015, the total length of oil and gas pipelines will exceed 150,000 kilometers, an increase of 90% over 2010. This means that new pipeline construction in the next four years will equal the previous 50 years combined, with a compound annual growth rate of at least 14%, providing opportunities for oil and gas pipeline companies.

       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.
