Strength of the Welded Joint of the Connecting Pipe and the Collector of the Boiler Primary Steam Superheater

  • Published:
Materials Science Aims and scope

The strength of the welded joint of the connecting pipe and the collector made of 12Kh1MF steel is investigated within the framework of the model of elastic solid, taking into account their real geometry and the dependence of the material characteristics on temperature. Zones of the maximum operating stresses in the joint for different types of welding are identified. Design and technological solutions aimed at significant reduction of the maximum operational stresses are proposed.
