42Crmo large diameter seamless steel pipe

 Seamless steel pipe refers to a steel pipe made of the whole round steel perforated and without welds on the surface. Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical crack pipes, boiler tubes, bearing tubes, automobiles, tractors, aviation high-precision structural steel pipes. Seamless steel pipe is a seamless steel pipe along the circumferential cross-section of the steel pipe, rolled by hot-rolled round steel. Because the seamless pipe is made of all steel, it has high strength and can withstand high pressure and temperature. In addition to hot rolling, seamless pipe can also be cold rolled and cold-drawn, and thin-walled, small, smooth surface products can be obtained. There are two kinds of seamless pipes: ordinary seamless steel pipes are used for water vapor, gas and mechanical parts, as well as various mechanical parts; Special seamless steel pipes include boiler steel pipes, drilling pipes, pumps, compressors, etc., which is a…
