Hydraulic Cylinder Pipe High Precision Burnished Steel

The steel pipes used in the hydraulic system are mainly stainless steel seamless pipes and ordinary seamless steel pipes. Although stainless steel seamless pipes have superior mechanical properties, they have not been widely used due to their high prices and low precision. Although ordinary seamless steel pipes are commonly used, they have poor mechanical properties and low precision. They usually go through a series of welding, trial assembly, pickling, alkali washing, water washing, long-term oil stringing, and leak testing before use. Complexity, time-consuming, unreliable materials, and the inability to completely remove the residues in the pipe, has become a major hidden danger for the entire hydraulic system to fail at any time. According to statistics, 70% of the failures in the hydraulic system are caused by this reason.

High-precision, precise and bright seamless steel pipes are special pipes for hydraulic systems.

1. Material selection: use metal bars with appropriate dimensions that meet national standards as raw materials for honing tubes;

2. Billet, free forging and heat treatment process: the raw material bar is processed by billet, free forging and heat treatment process;

3. Straightening: forging hammer straightening of the processed raw material bars;

4. Drilling deep holes: punch through holes of appropriate size in the raw material rods to make pipes;

5. Honing: Use honing stone to honing the through hole of the pipe, so that the through hole of the pipe meets the size and processing accuracy requirements of the honing pipe;

6. Lathe outer circle planing: The outer wall and end surface of the pipe are lathe and planed, so that the outer diameter of the pipe meets the size and processing accuracy requirements of the honing pipe, and the production of the honing pipe is completed. Honing is an effective machining method for machining inner holes, which not only has high productivity, but also high machining accuracy.
