The spiral submerged arc welding process has many advantages: first, it can use the same width strip steel to produce different diameters of steel tubes;Second, shape is easy to adjust, easy to change the specifications, both suitable for mass production, and suitable for small batch manufacturing;Third, the production process is easy to realize mechanization, automation and continuity.This is the main reason for the early development and market control of submerged arc spiral welded steel pipe.

In spiral steel pipe nondestructive testing of the quality management system, to the quality management system as the theoretical basis, using various methods and means of the various factors affecting the quality of spiral steel pipe nondestructive testing, including PDCA cycle, quality improvement tools, personnel training and so on, sums up the concrete measures and solutions to solve the problem.It provides a new idea and direction for the nondestructive testing quality management system of spiral steel tubes.Normally the straight seam welded pipe assembly design temperature must usually be for ease of operation, in this case, and may also be used in a pressure vessel in practice, on the basis of the corresponding temperature, the added margin coefficient (flange and bolt outside the exception).In the safety pressure relief device of pipeline, the safety pressure relief device of straight welded pipe indicates that the pipeline may exceed the normal working pressure during operation.The purpose of setting safety pressure relief device (such as safety valve, rupture disc, etc.The design pressure of straight welded pipe shall not be lower than the set pressure of safety pressure relief device.At present, various nondestructive testing methods in the production of spiral steel tubes are widely used in the fields of petroleum and natural gas, chemical industry, urban pipeline gas, etc., and any leakage or fracture failure in the transportation process will cause incalculable losses of spiral steel tubes
