Alloy seamless steel pipe/tube.

Alloy seamless steel pipe has a hollow section, no joints around the strip of steel. 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. The use of alloy seamless steel pipe to make ring parts can improve the utilization rate of materials. Alloy seamless steel pipe or a variety of conventional weapons indispensable material, gun barrel, barrel, etc., to be manufactured by steel pipe.
