Seamless Steel Pipe Standard
Jul 03, 2017

Seamless steel tube is a kind of steel strip with hollow section and without seams. Seamless steel pipe has a hollow section, can be used to transport fluid pipeline, such as the transmission of oil, natural gas, gas, water and some solid material pipeline. Compared with other solid steel seamless steel pipe steel, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold. The manufacture of ring parts with seamless steel tubes can improve material utilization, simplify manufacturing processes, save materials and work hours, such as rolling bearings, rings, Jack sleeves, etc., and are widely used in steel tube fabrication. Steel pipe or all kinds of conventional weapons indispensable materials, gun barrels are made of steel. The steel pipe can be divided into round tube and special-shaped pipe according to the sectional area shape. Because the circle area is the largest under the condition of equal circumference, more fluid can be transported with round tubes. In addition, the ring section in the internal or external radial pressure is more uniform force, so most of the steel pipe is round tube. However, the tube has some limitations, such as in the plane bending conditions, the tube is better than square and rectangular tube bending strength, and some agricultural machinery skeleton, steel, wood furniture, commonly used square, rectangular tube. According to different purposes, other sections of special-shaped steel pipe are needed.
