Type Analysis of the Principle of Ferrule Joint

The types of joints for pipelines include plastic, nylon, rubber, and steel pipes, which are selected based on the same working pressure. The type of instrument pipe joint is welding type pipe joint, which is suitable for connecting oil pipes with thick pipe walls. It mainly consists of joint body, nut, and connecting pipe. Screw the connector body into the body. Use a gasket (copper or nylon) for end face sealing. Use a shaped rubber sealing ring between the connector body and the connecting pipe for sealing. Alternatively, a spherical sealing structure can be used in systems with high pressure. Flared thin pipe joints are suitable for copper pipes and thin-walled steel pipes. Suitable for copper pipes and thin-walled steel pipes. It can also be used to connect nylon pipes and plastic pipes, using the expansion of the oil pipe end to seal under the clamping and tight pressure of the pipe sleeve and the conical surface of the joint body.

Stability is a performance indicator that is of great concern to instrument workers in chemical enterprises. Due to the relatively harsh environment in which instruments are used, the temperature and pressure changes of the measured medium are also relatively large. When instruments are put into use in this environment, the ability of certain components of the instruments to remain unchanged at any time will be reduced, and the stability of the instruments will decrease. There is currently no quantitative value for measuring or characterizing instrument stability.
