Structural Seamless steel tube, this standard applies to the general structure, mechanical structure of seamless steel pipe, fluid seamless steel pipe standard applies to the transport of fluids of the general seamless steel pipe. The main difference between it and structural seamless steel tube is fluid seamless steel tube by hydraulic test or ultrasonic, eddy current, magnetic leakage testing. Therefore, in the standard selection of pressure pipe pipe, it is not suitable to use fluid seamless steel pipe. The expression method of seamless steel tube is outer diameter and wall thickness. The thick wall seamless steel tube is mainly used for machining, coal mine, hydraulic steel and other purposes

Structural seamless steel tube advantages of high strength, good comprehensive performance, long service life, wide application range, and relatively economical. The steel is rolled into plates, profiles, seamless steel pipes, etc., and is widely used in bridges, ships, boilers, vehicles and important building structures.
