专家解读视频
This standard is included in DIN Handbook 403. Applies to welded circular tubes and pipes (hereinafter briefly referred to as 'tubes') with a longitudinal or spiral weld, made of unalloyed steels as listed in Table 1. These tubes are predominantly used in the construction of chemical plant, vessels, pipework and for general mechanical engineering purposes. They are designed to meet high performance requirements. Normally, there are no limiting values for the maximum permissible working pressure of these tubes. The permissible working temperature shall not exceed 300degreeC. (The upper yield stress values for tubes at temperatures up to 300degreeC are specified in Appendix A).
