Special shaped precision pipe is economic section steel pipe. It includes non-circular cross-section profile, equal wall thickness, variable wall thickness, variable diameter and variable wall thickness along the length direction, symmetrical and asymmetric cross-section, etc. Such as square, rectangular, conical, trapezoidal, spiral tube and so on.
The cross-section shape of the special-shaped precision tube is the precision tube of other shapes except the circular shape
Special shaped precision tubes are widely used in parts and structures. Compared with the round pipe, the precision special-shaped pipe has greater bending resistance and section modulus, which can greatly reduce the structural weight and save steel.
Precision profiled pipe is mainly used in automobile manufacturing industry. Electrical gas transmission, machinery manufacturing also use precision special-shaped pipe, water power generation fluid pipeline, processing machinery accessories, bearings, etc. It can also be used in high pressure oil pipe, precision equipment, motor shell and DC motor barrel. Boiler equipment, etc; It can also be used in precision special-shaped tube and DC motor middle cylinder.
Application of finish rolling precision profiled steel pipe:
1. Special shaped steel tubes are widely used in daily necessities, aircraft and rocket manufacturing, radio communication, atomic power station and space technology;
2. In terms of machine manufacturing, special-shaped pipes are used to manufacture hollow transmission shafts, pistons, various tools, fasteners, watch cases and various mechanical parts of motor vehicles. The special-shaped pipe not only makes the mechanical design more reasonable, but also reduces the weight of the equipment;
3. In terms of construction, doors and windows made of special-shaped pipes are not only light and durable, but also cheap in cost;
4. In the structure of bicycles, motorcycles, tractors, automobiles and buses, a large number of thin-walled special-shaped pipes are widely used. The cross-section coefficient of the pipes is large, the bending and torsion resistance are strong, and the surface is smooth and smooth, so the weight is relatively light. In the trolley bus, the variable cross-section pipe is used to manufacture the collector pole, because the special-shaped pipe has good toughness and elasticity;
5. Special shaped tubes are widely used in instruments, telecommunication equipment and medical devices to make supports, guide rails, and the frames of boxes and cabinets, which make them light in weight, beautiful in shape, novel in style, and convenient in handling and carrying.
