[0002] A sealing gasket is a gasket used for sealing at the interfaces of machinery, equipment, pipelines, etc. It is usually made of rubber, plastic, metal and other materials. The main function of a sealing gasket is to fill the tiny gap between the two mating surfaces to prevent leakage of fluids (such as gas, liquid, etc.). Different types of sealing gaskets have different characteristics and applicable scenarios. For example, rubber sealing gaskets have good elasticity and sealing properties and can adapt to certain temperature and pressure changes; metal sealing gaskets have higher strength and can maintain sealing effects in harsh environments such as high temperature and high pressure. In many industrial fields, the quality and performance of sealing gaskets are crucial to the normal operation and safety of equipment.

However, rubber gaskets have low strength and poor pressure-bearing capacity, which shortens the service life of rubber gaskets. Moreover, when replacing rubber gaskets, the pipes need to be disassembled, and the replacement process is time-consuming and labor-intensive, with poor adaptability and practicality.
