side impact beams

Tube material supply, the pipe material used for hot rolled tube or semi-finished goods, extruded tube, and welded tube; Tube material preparation, including inspection, baling, pickling, cleaning, washing, neutralization, drying and coating lubricant, etc.; Cold (cold rolled or cold drawn); Finished product finishing including finished heat treatment, leveling, sampling, cutting head to tail, examination (manual inspection and various testing), oil water pressure test, painting, packaging, warehousing, etc. The difference between different products finishing content.
Cold drawn steel tube with inside and outside the wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks and surface already make antirust processing, mainly used in the mechanical structure, hydraulic equipment and automobile motorcycle pneumatic or hydraulic components, such as a cylinder or cylinder, etc.
Cold drawn steel tube basic process is: hot-rolled capillary, capillary inspection, grinding, capillary pickling, capillary rechecked after pickling, cold drawing, fine pulls time before straightening, acid cleaning, lubrication, fine. Before cold drawn steel tube cold drawing attention should be paid to matters of pickling thoroughly, once found not remove all rust, needs to pickling. In production, often should test the phosphating liquid and saponification liquid composition concentration, to ensure that the phosphating liquid and saponification liquid production index, found short of indicators, shall be prepared in the timely. We will strictly control of dealing with the fluid temperature and operation time.
Precision steel tube is a kind of after cold drawn or hot rolling process of a kind of high precision steel tube material. Precision steel tube wall without oxidation layer, inside and outside the leak-off is under great pressure, and high degree of side impact beams finish, cold bending deformation, flaring, flattening without cracks, etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, can be a seamless steel pipe, welded pipe.
High precision steel tube high dimensional accuracy, tube inside and outside surface finish, steel after heat treatment without oxidation film, both internal and external surface steel tube flaring, flattening without cracks, cold bending deformation, and can bear high pressure, can make all kinds of complex deformation and mechanical processing processing.
Mainly produces steel grades: 10, 20, 40 cr, 35, 45, 42 crmo, 16 mn etc. Precision steel tube is a kind of after cold drawn or hot rolling process of a kind of high precision steel tube material. Because of the precision steel tube inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks etc, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, can be a seamless steel pipe, welded pipe.
Pole difference: seamless steel tube main characteristic is a welding seam, can withstand greater pressure. Products can be very rough as-cast or cold dial. Precision steel tube is the modern products, mainly is the internal hole, the size side impact door beams of the outer wall with strict tolerance and roughness. Features: outer diameter smaller. High precision to do small batch. Cold drawn finished products of high precision, good surface quality. Steel pipe transverse area is more complex. Steel pipe is superior performance, dense metal.
On the basis of the processing properties of the metal, pipe size, quality, investment aluminium coated steel tube and benefit to choose different processing methods and the corresponding auxiliary process.
