Product Description

Introduce

It is an economic cross-section steel pipe. This includes cross-sectional contours that are non circular, of equal wall thickness, of varying wall thickness, of varying diameter and wall thickness along the length direction, and of symmetrical and asymmetric cross-sections. Such as square, rectangular, conical, trapezoidal, spiral, etc. Specially shaped steel pipes are more suitable for the unique usage conditions, saving metal and improving labor productivity in component manufacturing. It is widely used in aviation, automobiles, shipbuilding, mining machinery, agricultural machinery, construction, light textile, and boiler manufacturing. The methods for producing shaped pipes include cold drawing, electric welding, extrusion, hot rolling, etc. Among them, the cold drawing method has been widely used.
