Shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless steel pipe (code BD), variable diameter special-shaped seamless steel pipe (code BJ). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
Seamless square pipes and seamless rectangular pipes are also special-shaped seamless steel pipes. The weight calculation method of seamless square management theory: (side length + side length) × 2 × wall thickness × 0.00785 × length; seamless square management theory weight calculation method :Side length x 4 x wall thickness x 0.00785 x length.
Special pipe
Special-shaped pipe is made of a variety of special-shaped seamless steel pipe by cold drawing, is in addition to the round pipe other cross-section shape of seamless steel pipe.
Steel pipe can be divided into oval shape, triangle shape steel, hexagonal shaped steel tube, diamond shaped steel tube, octagonal steel tube, round deformed steel circle, not equilateral hexagon five disc shaped steel tube, the plum blossom shaped steel tube, double double concave and convex shape of steel pipe, steel pipe, melon seeds shaped steel tube and cone shaped steel tube, corrugated shape profiled steel pipe and so on.
Compared with the circular pipe, the special-shaped pipe generally has a larger moment of inertia and section modulus, with a larger bending and torsional resistance, can greatly reduce the weight of the structure, save steel.
The special-shaped seamless steel pipe is widely used in all kinds of structural parts, tools and mechanical parts, such as
petroleum, chemical, medical, food, light industry, mechanical instrument and other industrial pipeline and mechanical structure parts.
The development of special-shaped tube is mainly the development of product varieties, including the shape of section, material and performance.Extrusion method, oblique die rolling method and cold drawing method are effective methods to produce special-shaped pipes, which are suitable for producing special-shaped pipes of various sections and materials.In order to produce a wide variety of special-shaped tubes, we must have a variety of production means.On the basis of the original only cold drawing, it has developed dozens of production methods such as roll drawing, extrusion, hydraulic, rotary rolling, spinning, continuous rolling, rotary forging and die - free drawing, and is constantly improving and creating new equipment and technology.
Before the special-shaped tube leaves the factory, it can do various performance index analysis according to the need, such as plasticity, hardness, fatigue, strength and impact toughness test
