Alloy seamless steel pipe is a kind of seamless steel pipe, its performance is much higher than that of ordinary seamless steel pipe, because there are more Cr in this kind of steel pipe, and its performance of high temperature, low temperature and corrosion resistance is inferior to that of other seamless steel pipes, so alloy pipe is widely used in petroleum, chemical industry, electric power, boiler and other industries.
Alloy seamless steel pipe includes silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc.
Seamless steel tube is a long steel with hollow section and no joints around. The steel pipe has a hollow section, which is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe is a kind of economical section steel with the same bending and torsional strength. It is widely used in the manufacture of structural parts and mechanical parts, such as oil transportation, stair handrail, bicycle frame and steel scaffold used in construction. Using alloy seamless steel pipe to make ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, Jack sets, etc., which have been widely used in steel pipe manufacturing. Alloy seamless steel pipe is also an indispensable material for all kinds of conventional weapons, and the barrel, barrel, etc. should be made of steel pipe. In addition, when the circular section bears the internal or external radial pressure, the force is relatively uniform. Therefore, most of the alloy seamless steel tubes are round tubes
