[0002] Hydraulic cylinders, as a widely used piece of industrial automation equipment, play a vital role across various industries. They primarily consist of several core components: the cylinder barrel, piston, and piston rod. Hydraulic cylinders utilize the pressure of hydraulic oil to drive the piston rod's extension and retraction, thereby achieving mechanical motion. Oil pipes, a crucial accessory for hydraulic cylinders, are responsible for transporting the hydraulic oil. Their performance directly impacts the cylinder's ability to operate smoothly and properly.

[0003] However, in actual use, oil pipes often face various challenges. Because they are exposed to the external environment for long periods of time, they are susceptible to damage from external factors. For example, accidental impacts or scrapes can cause scratches or even more serious damage to the pipe. If the surface of the pipe is severely damaged, it not only affects its appearance but, more importantly, may degrade its sealing performance, thereby affecting the proper functioning of the hydraulic cylinder. In such cases, the entire pipe must be replaced, which not only increases maintenance costs but can also cause production downtime and affect work efficiency.
