Compared with seamless pipes, the equipment of high-frequency welded pipe units is characterized by strong continuity, high efficiency, and low cost in welded pipe production. At the same time, the production of raw material strips is developing rapidly, and welded pipes account for an increasingly large proportion of the entire pipe material. The production of high-frequency welded pipe units has the characteristics of no pollution and low noise in terms of production efficiency and economic benefits, and does not produce wastewater or exhaust gas. Circulating water cooling is used in production, which is energy-saving, environmentally friendly, and labor-saving. Only 5-8 people are needed per shift. In terms of usage, with the improvement of weld quality and non-destructive testing reliability of welded pipes, the use of welded pipes is becoming increasingly widespread, replacing seamless steel pipes in more departments and applications. The growth rate of welded pipes is greater than that of seamless pipes, which is the overall trend of development. The high-frequency welding process has advantages in many aspects, and has a wide adaptability to the material of the pipe blank and the specifications and dimensions of the steel pipe. High frequency welding not only improves the welding speed, but also can obtain welds with small heat affected zones and good burn through properties.
In terms of quality, the high-frequency welded pipe unit has the advantages of good weld quality, small internal and external burrs, high welding speed, and low power consumption, which can be widely applied and promoted. High frequency welded pipe units can normally produce opposite sex pipes, and also produce square and rectangular pipes. Due to the large cross-sectional modulus of square and rectangular pipes, they can withstand greater bending forces, save a lot of metal, save processing time, and reduce component weight. Therefore, they are widely used in various fields of industry and agriculture.
