Stainless steel seamless steel pipe is a long strip of steel with hollow section and no joints around it. Stainless steel seamless pipe
Features of stainless steel seamless pipe:
First, the thicker the wall thickness of the product, the more economical and practical it will be. The thinner the wall thickness, the higher its processing cost will be; Secondly, the process of the product determines its limited performance. Generally, the accuracy of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surface of the pipe, high sizing cost, and there are pockmarks and black spots on the inner and outer surface, which are not easy to remove; Third, its detection and shaping must be processed offline. Therefore, it embodies its advantages in high pressure, high strength and mechanical structure materials
Weldability analysis of P92 steel
The toughness of weld is lower than that of base metal
The weld metal is a cast structure cooled down from the melting state with very high temperature. It has no chance to go through the TMCP process (thermal mechanical control process), that is, the thermal control rolling process. The grain can not be refined. Nb and other microalloyed elements are still solid in the matrix, so there is no chance to fully analyze it.
Welded joint is the weakest link affecting the operation safety of the unit
Due to the high content of alloy elements in P92 steel and great technical difficulty in welding, P92 steel is prone to low impact energy of joints and early failure of type IV cracking in long-term operation. If the welding quality is not guaranteed, the advantages of P92 will no longer exist and pose a threat to the operation safety of the unit.
