Introduction
Seamless steel pipe is perforated by the whole round steel, and the steel pipe without weld on the surface is called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold drawn seamless steel pipe, extruded seamless steel pipe, pipe jacking, etc. According to the section shape, seamless steel pipes are divided into circular and special-shaped pipes. Special-shaped pipes have many complex shapes, such as square, oval, triangular, hexagonal, melon seed, star and winged pipes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick wall seamless steel pipe and thin wall seamless steel pipe. Seamless steel pipe is mainly used for petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe and high-precision structural steel pipe for automobile, tractor and aviation
T92 / P92 steel is a new material used in the main steam and reheat hot sections of ultra supercritical units at present. It is difficult to weld and has strict process requirements. It has strict process requirements in preheating, welding current, interlayer thickness, weld width and post weld treatment, and is prone to crack defects. The following editor will introduce the chemical composition, weldability and key points of welding process of P92 steel.
