Special-shaped steel pipes refer to steel pipes with non-circular cross-sectional contours, constant wall thickness, variable wall thickness, variable diameter and wall thickness along the length direction, symmetrical and asymmetrical cross-sections, such as square, rectangular, tapered, trapezoidal and spiral tubes, etc.
Precision rolled shaped steel has a wide range of uses:
1. Special-shaped steel pipes are widely used in daily necessities, aircraft, rocket manufacturing, radio communications, atomic energy power stations, and space technology;
2. In terms of machine manufacturing, special-shaped tubes are used to manufacture hollow drive shafts, pistons, various tools, fasteners, watch cases, and various mechanical parts for motor vehicles. Special-shaped tubes not only make the mechanical design more reasonable but also reduce the weight of the equipment;
3. In terms of construction, special-shaped tubes are used to make doors and windows, which have a lightweight, durable and low-cost structure;
4. Thin-walled special-shaped pipes are widely used in the structural parts of bicycles, motorcycles, tractors, cars, and large buses. This kind of pipe has a large section coefficient, strong bending resistance, torsion resistance, and surface smoothness, so it is lighter in weight. At the same time, variable cross-section tubes can also be used to make collector poles on trolleybuses because this special-shaped tube has good toughness and elasticity;
5. In instruments, telecommunications equipment, and medical equipment, special-shaped tubes are widely used to make brackets, guide rails cabinet frames, etc., making them lightweight, beautiful in appearance, novel in style, and easy to handle and carry.
