wholesale Cold-rolled Tube steel tube structure: Shaped steel tube for economical section. Including cross section, non-circular, equal wall thickness, variable wall thickness, varying diameter and wall thickness along the length, cross section symmetry and asymmetry, etc. Such as square, rectangle, cone, trapezoid, spiral and so on. Special shaped steel pipe can adapt to the special conditions of use, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, building, textile and boiler manufacturing and so on. The methods of producing special tubes are cold drawing, electric welding, extrusion and hot rolling, among which cold drawing method has been widely used. Shaped steel tube application: Special shaped seamless steel tubes are widely used in various structural parts, tools and machinery parts. Compared with the circular tube, the special-shaped tube generally has larger inertia moment and sectional modulus, and has greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel. Shaped steel tube Molding method: Shaped steel pipe, special-shaped steel tube bending forming, this form, which is commonly known as bending. Special shaped steel tube bending is divided into two kinds, one kind of real bending, another empty bending. The true bending of square tubes is compacted, and then the bending of the inner and outer roller tubes, shaped steel tubes inside and outside the wall compaction is a two-way process. The real bending rectangular tube has the advantages of solid bending will be relatively small, and the formation of a more accurate, and in the production time, as long as the use of roller is accurate, and the angle shaped steel tube forming steel pipe internal rebound after the more accurate, we can ensure accurate. Production of air bending of rectangular tube, the outer wall of the tube outside and square shaped steel tube and roller, and metal bending, bending of the empty time, pipe bending curve will produce a certain compression, so the compression effect, zigzag line longitudinal variable length, rectangular tube bending metal will become thick air compression bending. Or thickening effect. The two production methods, two basic ways of rectangular tube production square and special-shaped steel tube molding, according to the needs of different products, select the appropriate process configuration. It should be noted that, when stretched and compressed, the impression on the quality of the product, or lead to square tube deformation. Trict contract auditing invloved all departments to assure the feasibility of each order. Process design and validation before bulk production. Strictly control on all raw and auxiliary materials, All raw materials reach the world advanced level. On-site inspection to all processes, inspection record keep traceable for 3 years.
