It includes two types of seamless steel pipes and welded steel pipes. The welded steel pipe pipes, which was commonly used in oil pipelines in China, are spiral submerged arc welded pipes , straight seam submerged arc welded pipes and electric resistance welded pipes . Steel pipes are generally used when the pipe diameter is less than 152 mm.

Difference between ERW Pipes, SSAW Pipes and LSAW Pipes SSAW pipes produced by traditional technique are widely used in the project of natural gas transmission from West to East China. The US, Japan and Germany believe that its not suitable to use SSAW pipes as main trunk; Canada and Italy use it partially and Russia use it
Large-diameter seamless steel pipe are those with an outer diameter exceeding 100 mm, wall thickness greater than 0.2, and the outer diameter of a pipe, and large-diameter seamless steel pipes are pierced with steel ingots or solid pipes, and then hot-rolled, cold-rolled, or cold dialed. At present, China's large-diameter seamless steel tubes mainly produce large-diameter seamless steel tubes.
Large Diameter Welded Pipe for sale - threewaysteelLarge diameter welded pipe is mainly used for conveying water, gas, air, oil and heating hot water or steam, such as generally low pressure fluid and other use pipe. Large diameter welded steel pipe surface allows the existence does not exceed the negative deviation of thickness of scratch, scratch, weld dislocation, burns and scarring and other minor defects.
SSAW (Spiral Submerged- Arc Welded) steel pipes are made of narrower hot rolled plates/coils, which lowers their costs. The diameter of spiral welded steel pipe can be very large, suitable for transporting large amounts of oil and natural gas.
