Abstract

The invention discloses a steel pipe used for a shock absorber. The steel pipe comprises a steel pipe body, a first damping shock absorption layer, a Ni-Co alloy coating layer, a second damping shock absorption layer and a Fe-Ni-W alloy coating layer; the first damping shock absorption layer and the Ni-Co alloy coating layer are arranged on the inner surface of the steel pipe body from outside to inside, the second damping shock absorption layer and the Fe-Ni-W alloy coating layer are sequentially arranged on the outer surface of the steel pipe body from inside to outside; and according to the above manner, the steel pipe is simple in structure, good in damping shock absorption performance and capable of prolonging the service life of the shock absorber.

Description

technical field [0001] The invention relates to the field of steel pipes, in particular to a steel pipe used for shock absorbers. Background technique [0002] Steel pipe is a kind of hollow long steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used. For the manufacture of mechanical parts and engineering structures. [0003] Steel pipes can be divided into two categories according to the production method: seamless steel pipes and seamed steel pipes, and seamed steel pipes are referred to as straight seam steel pipes. According to the production method, seamless steel pipes can be divided into: hot-rolled seamless pipes, cold-drawn pipes, precision steel pipes, hot-expanded pipes, cold-spinned pipes, and extruded pipes. Seamless steel pipes are made of high-quality carbon steel or alloy steel, an...
