The development of automobile industry needs all kinds of metal and non-metal materials. Among them, metal material is the material with the largest amount, and its varieties are mainly strip, profile and steel pipe. Among the automotive materials, seamless steel tubes amounted to 8.11 million tons and welded steel tubes amounted to 530,000 tons. Although the amount of steel pipe is not much, but it is very important, the car's controller, steering shaft, shock absorber, front axle assembly, constant speed section drive shaft, muffler, rear axle suspension arm and cooling water device and other components are composed of all kinds of steel pipe, it can be said that there is no steel pipe car can not start.

Cars are required to be beautiful in appearance, light in weight, safe and smooth in running, so strict requirements are put forward for steel tubes used in cars in dimension accuracy, mechanical properties, technological properties and surface quality. And precision steel tube, is a seamless steel tube production process. Finish rolled pipe is one of the highest grade seamless steel pipe products. It has the characteristics of high precision and surface finish requirements, the inner wall of the fine rolled tube is smooth, so the surface of the oxide layer will almost not appear. Secondly, the comprehensive performance of the fine rolled pipe is very good, can carry a lot of force and high pressure, and the cold bending and flaring is also very good, even by gravity, there will be no cracking and wrinkling problems.

The precision seamless steel pipe and precision welded steel pipe produced by our company are made of high quality billets. The seamless steel pipe produced by our company is characterized by high precision, high finish, clean inner and outer wall of the steel pipe, no oxidation layer, and the mechanical and technological performance is better than that of other factories. The steel tube can withstand high pressure under various operating conditions, no leakage phenomenon under high pressure, no deformation in cold bending, no crack in flaring and flattening, and has good performance against tension and impact. The new product "carbon steel mirror anti-rust seamless steel pipe" its surface layer by the mirror anti-rust infiltration treatment, more excellent anti-corrosion effect, the comprehensive quality of steel pipe relative to Germany, Japan, the United States and other foreign imports of seamless steel pipe quality is better. In terms of accuracy, the tolerance of outer diameter and inner hole can reach ±0.03mm, ±0.05mm, ±0.1mm, which can be selected according to the company's process requirements.
