Our Advantages

Product process

The production process of special-shaped steel pipes is like a carefully choreographed dance, and each step is full of the fusion of technology and wisdom.

The first is the selection of raw materials. High-quality steel is the cornerstone of high-quality special-shaped steel pipes. Steel with good ductility and strength is usually selected to ensure the smooth progress of subsequent processing.

 

Next, enter the key forming link. In this process, a variety of advanced technologies are used, such as cold bending and hot extrusion. Cold bending gradually bends the steel through the mold to gradually present a special-shaped outline; hot extrusion is to extrude the steel into the desired shape under high temperature and high pressure. The formed steel pipe also needs to be precisely welded. Advanced welding technology can ensure the firmness and uniformity of the weld, and ensure the overall strength and sealing of the steel pipe.

 

Then comes the heat treatment link. Through annealing, quenching and other

processes, the internal organizational structure of the steel pipe is improved and its mechanical properties are improved. In the surface treatment stage, the steel pipe is galvanized, painted and other treatments are performed to enhance its corrosion resistance and aesthetics. After a series of rigorous tests, only special-shaped steel pipes that meet the standards can finally go to the market.

Application

Special-shaped seamless steel pipe is widely used in various structural parts, tools and mechanical parts. Compared with round pipe, special-shaped pipe generally has larger inertia moment and section modulus, and has greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.

Specially shaped pipes are generally distinguished according to the cross section. According to the material, they can be divided into seamless steel pipe special-shaped pipes, aluminum alloy special-shaped pipes, and plastic special-shaped pipes. The following is mainly about steel pipe specials. The steel pipe special-shaped pipe can be divided into elliptical special-shaped steel pipe, triangular special-shaped steel pipe, hexagonal special-shaped steel pipe, rhombic special-shaped steel pipe, octagonal special-shaped steel pipe, semicircular special-shaped steel circle, unequal hexagonal special-shaped steel pipe, five-petal plum shaped special-shaped steel pipe, double-convex special-shaped steel pipe, double-concave special-shaped steel pipe, melon shaped special-shaped steel pipe, conical special-shaped steel pipe, corrugated special-shaped steel pipe.
