Spiral Submerged-Arc Welded Steel Pipe design coefficient development of steel pipe. Another development direction to improve gas transport capacity is to improve the design coefficient of pipeline.ASME b31.8-2010 stipulates that 0.8 design coefficient is allowed when pipelines are Spiral Submerged-Arc Welded Steel Pipe built in the first-class and first-class areas in sparsely populated areas.At present, the maximum Spiral Submerged-Arc Welded Steel Pipe design coefficient of domestic pipelines is basically 0.72, while 0.8 design coefficient is achieved in some pipelines abroad.Since the 1990s, Spiral Submerged-Arc Welded Steel Pipe countries such as the United States and Canada have increased the Spiral Submerged-Arc Welded Steel Pipe design coefficient to 0.8 or 0.83 in the first category of the design standard and adopted this coefficient in the design of the us-canada alliance oxygen pipeline, rocky pipeline, Alaska Spiral Submerged-Arc Welded Steel Pipe natural gas pipeline and other pipelines.Compared with the Spiral Submerged-Arc Welded Steel Pipe traditional maximum design coefficient of 0.72, 0.8 design coefficient can reduce the wall thickness of steel pipe by 10% without raising the steel grade, thus Spiral Submerged-Arc Welded Steel Pipe reducing the steel consumption of pipe by about 10%.Therefore, the development and application of 0.8 design coefficient X80 steel grade helical ssaw pipe has important economic and social benefits.
