Special tube product details

Special shaped seamless steel pipe is a kind of seamless steel pipe except for round pipe.

Shaped tube, square tube, rectangular shaped profiled pipe, special-shaped pipe, spiral pipe, specification: 20*20mm-500mm, thickness 0.6mm-20mm, spiral steel pipe specifications, 219mm-2020mm, wall thickness 5mm-20mm. straight specifications are 4 points, 6 points, 1 inch, 1.2 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 4 inch, 5 inch, 6 inch, 8 inch, 102, 108, 127, 133, 139, 159, 168, 177, 194, 219, 273, 325 and other specifications generally refers to the special pipe rectangular tube.

Classification of shaped tube

According to the different shapes and sizes of steel pipe section can be divided into the same thickness of the special-shaped seamless steel pipe (code named D), unequal wall thickness of seamless steel tubes (code named BD), variable diameter seamless steel pipe (code named BJ).

Special shaped pipe is generally divided according to the broken section, according to the material can be divided into seamless steel pipe, aluminum alloy special-shaped tube, plastic tube. The following describes the steel pipe.

Tube shaped tube can be divided into oval shaped steel tube, triangular shaped steel tube, hexagonal shaped steel tube, diamond shaped steel tube, octagonal shaped steel tube, semi circular shaped steel circle, not equilateral hexagon shaped steel tube, the five petal quincunx shaped steel tube, double convex shaped steel tube, double concave shaped steel tube, conical shaped, oval shaped shaped steel tube steel pipe, corrugated steel pipe.

Special pipe use range

Shaped seamless steel pipe is widely used in various structural parts, tools and machinery parts. Compared with the circular tube, the special shaped tube has the larger inertia moment and the section modulus, and the utility model has the advantages of large bending and torsion resistance.
