Alloy seamless pipe is mainly used for power plant, nuclear power, high-pressure boiler, high-temperature superheater, reheater and other high-pressure and high-temperature pipes and equipment. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. 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. Aluminum alloys pipe usually use copper, zinc, manganese, silicon, magnesium and other alloy elements, compared with ordinary carbon steel has a lighter and corrosion resistance, but corrosion resistance is not as good as pure aluminum. In a clean, dry environment, the surface of the aluminum alloy forms a protective oxide layer.
