Steel tubes made of a single piece of metal with no seams on the surface are called seamless steel tubes. According to the production method, seamless pipe is divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extrusion pipe, pipe jacking and so on. According to the section shape, the seamless steel pipe is divided into round and irregular two kinds, irregular pipe has square, oval, triangle, hexagonal, melon seed shape, star shape, with a variety of complex shapes. [1] The maximum diameter is 650mm and the minimum diameter is 0.3mm. Depending on the use, there are thick wall and thin wall tube. Seamless steel pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and automobile, tractor, aviation high-precision structural steel pipe.

What are the uses of seamless steel pipe

Seamless steel pipe has hollow section, widely used for conveying fluid pipeline, such as conveying oil, natural gas, gas, water and some solid materials, etc. Compared with solid steel such as round steel, steel pipe is a kind of economic section steel because of its light weight and the same bending and torsional strength.

Performance index of steel pipe

The mechanical property of steel is an important index to guarantee the final serviceability (mechanical property) of steel, which depends on the chemical composition and heat treatment system of steel. In the steel pipe standard, according to different use requirements, the tensile properties (tensile strength, yield strength or yield point, elongation) and hardness, toughness indicators, as well as user requirements of high, low temperature performance.
