What are the surface treatments of EN 10294-1 E355+N seamless pipes

  EN 10294-1 Grade E355+N mild steel seamless pipes are available in thicknesses ranging from 3mm to 100mm, outer diameters from 8mm to 250mm and inner diameters from 5mm to 700+mm. The shape of the pipe can be produced into a round pipe, and it can be produced into a square pipe or other special-shaped pipe by extrusion or welding. The surface finish can also be processed by cold drawing, centerless grinding, hot rolling, smooth turning and peeling.

What are the applications of steel pipes in the automobile manufacturing industry?

图片
Cars are the daily necessary means of transportation for the public. The manufacture of cars is inseparable from steel pipe products. Let us take a look at the parts of the car that are composed of steel pipes: CCB pipe fittings CCB is mainly used to support man-machine interface control equipment and decorative parts, and at the same time form a safety system with other safety structures. The structure is simple and mainly includes a pipe beam, a side end support, a pipe column fixing support assembly, a lower support leg and an auxiliary support. Seat post It acts as a support structure within the car seat cover, allowing the seat to retain its structural shape. Trunk hinge The trunk hinge is the connecting mechanism of the trunk door of the car. Due to the opening angle of the trunk door, the hinge needs to bear the weight of the trunk door, so the hinge also needs to play a supporting role. Door anti-collision tube When the side door is hit, the sturdy high-strength anti-collision ...
