Seamless steel pipe is a long strip of steel with hollow section and no joint around it. Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe is lighter in weight when its bending and torsional strength is the same. It is an economic section steel. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring parts with steel pipes can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing rings, Jack sleeves, etc. at present, steel pipes have been widely used for manufacturing. Steel pipe is also an indispensable material for all kinds of conventional weapons. Gun barrel and barrel should be made of steel pipe. Steel pipe can be divided into round pipe and special-shaped pipe according to different cross-sectional area and shape. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform. Therefore, the vast majority of steel pipes are round pipes
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.
