在压力容器的焊接接头设计中,几乎都要涉及到接管与器壳连接的角焊缝。随着化工技术的发展,装置的大型化,高强度合金钢的采用,对容器接管角焊缝提出了越来越严格的要求。尤其那些处于苛刻工况下的容器,如疲劳容器、低温容器、防腐容器等,角焊缝的质量好坏也将直接影响容器的正常使用和寿命。从以往容器破坏的实例也可证实这一点。因此,对接管角焊缝的设计、制造和检验要予以足够 In the design of pressure vessel welding joints, almost all the fillet welds connected with the shell are taken into account. With the development of chemical technology, the use of large-scale and high-strength alloy steels has put more and more strict demands on the joint fillet welding of containers. In particular, those under harsh conditions containers, such as fatigue containers, cryogenic containers, preservative containers, etc. The quality of fillet welds will also have a direct impact on the container’s normal use and life. This is also evidenced by the destruction of containers in the past. Therefore, the design, manufacture and inspection of butt welds shall be sufficient
