The light weight of seamless steel pipe is only 1/5 of that of square steel, which makes it more convenient in transportation and installation. At the same time, seamless steel pipe also has excellent corrosion resistance, can remain stable in acid, alkali, salt and atmospheric environment, and has excellent high temperature resistance, impact resistance and fatigue resistance, and its effective service life can reach more than 15 years.

In practical application, because of its continuous internal structure and high elasticity, seamless steel pipe will not deform after repeated use in mechanical equipment, and its tensile strength is more than 8-10 times that of ordinary steel, and its elastic modulus is better than that of steel, so it has excellent creep resistance. These characteristics make seamless steel pipe widely used in oil transportation, natural gas, gas, water and some solid materials transportation.
