Tip: What does a shock absorber do?
Essentially, shock absorbers do two things. Apart from controlling the movement of springs and suspension,
shock absorbers also keep your tyres in contact with the ground at all times. At rest or in motion, the bottom
surface of your tyres is the only part of your vehicle in contact with the road.
Features of precision steel tube for gas springs
1. The outer diameter is smaller.
2. High precision and small batch production.
3. The cold drawn finished product has high precision and good surface quality.
4. The cross-sectional area of the steel pipe is more complicated.
5. The performance of the steel pipe is better and the metal is denser.

Calculation formula of precision steel pipe::[(outer diameter-wall thickness)*wall thickness]*0.02466=kg/meter (weight per meter)
Application of carbon steel precision tube:
Motorcycle front fork ,Motor outer shell,Automobile shock absorber cylinder,Dust cover,Automobile shock
absorber reservior,
refrigaretion gas reservior
Production process : Material incoming inspection Surface treatment,Cold rolling Inspection,Rust preventive
work,Warehouse
storage .
TIP:
Cold-drawn precision tube is to use a cold-drawing machine for metal construction without heating. The advantage is that it does
not need to be carried out at high temperature. The tensile strength obtains better mechanical properties. Cold drawn (rolled) fine
seamless steel pipe process: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating)
→ multi-pass cold drawing (cold rolling) → billet → heat treatment → straightening Straight → hydraulic test (flaw detection) →
symbol → storage.
The difference between cold drawing and cold drawing technology:
Cold drawing and cold drawing are two different methods of metal cold working, and the two are not the same concept. Cold drawing
refers to the method of applying pulling force on both ends of the metal material to cause the material to be stretched and deformed.
Cold drawing refers to the method of applying a pulling force on one end of the material to pull the material out through a die hole.
The diameter of the die is larger than that of the material. diameter is smaller. In addition to stretching deformation, the material is
subjected to extrusion deformation by cold drawing. Cold drawing is usually carried out on a special cold drawing machine.
