Seamless Alloy Steel Pipe Application
Seamless Steel Tube: a long strip of steel with a hollow section and no seams on the sides. Steel tubes with hollow sections are widely used as conduits for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe has the same bending and torsional strength and is lighter in weight. It is a kind of economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil transportation, stair handrails, bicycle racks and steel scaffolding used in construction. Alloy seamless steel pipe manufacturing ring parts, can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, jack sleeve, etc., has been widely used to manufacture steel pipe. Alloy seamless steel pipe or a variety of conventional weapons indispensable material, barrel, barrel, etc. to steel pipe to manufacture. In addition, the annular section under internal or external radial pressure, the force is more uniform, so the vast majority of alloy seamless steel pipe is round pipe
