Special-shaped pipes and elliptical pipes

High precision and corrosion resistance: Some special-shaped pipes, such as seamless steel pipe special-shaped pipes, have characteristics such as high precision and corrosion resistance, which enable them to meet application scenarios with high precision and performance requirements.

Elliptical pipe

Raw materials need to go through steel coils, acid pickling, rolling, annealing, and slitting to obtain finished steel strips of the corresponding scale. Steel coils are divided into hot-rolled and cold-rolled materials, and rolling is further divided into rough rolling and precision rolling.

Elliptical pipe

Elliptical tubes are generally extruded into the shape of duck eggs based on circular tubes. Elliptical tubes are divided into regular ellipses and flat ellipses. Regular ellipses refer to duck egg shapes with symmetrical curvature, while flat ellipses refer to two long faces parallel to straight lines and two short faces forming a circular arc shape. It is mainly widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical, diagnosis and treatment, food, light industry, mechanical instruments, etc.

Spiral steel pipe

Spiral steel pipe is a type of spiral seam steel pipe made from strip steel coil as raw material, extruded at room temperature, and welded using automatic double wire double-sided submerged arc welding technology.

Thick-walled tapered steel pipe

Cone tube, also known as cone tube, is a hollow cone tube made from sheet or pipe material and produced through thermal expansion or rolling processes with different diameters at both ends.
