    Steel pipe is a hollow strip of steel that is used extensively for transporting fluids such as oil, gas,

    Water, gas, steam, etc., in addition, in bending, torsional strength at the same time, lighter weight, so it is also widely used

    To manufacture mechanical parts and engineering structures.  Also commonly used for the production of conventional weapons, gun barrels, shells and so on.

    Classification of steel tubes: steel tubes are divided into seamless steel tubes and welded steel tubes (with crimson tube).  According to the section shape and

    Can be divided into round pipe and special-shaped pipe, widely used is round steel pipe, but there are some square, rectangular, semicircle,

    Hexagonal, equilateral triangle, octagonal and other special-shaped steel pipes

    Steel tubes made of a single piece of metal without 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, etc.  According to the shape of section, seamless steel tube is divided into round and special-shaped, special-shaped tube has square, oval, triangle, hexagonal, melon seed, star, winged tube and a variety of complex shapes.  According to different uses, there are thick wall pipe and thin wall pipe.  Seamless steel pipe is mainly used as petroleum geology drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and automobile, tractor, aviation high-precision structural steel pipe
