1. The flange can be dismantled and can withstand small pressure and great pressure. Still not afraid of vibration.
2. The thread is convenient, the stable pipeline, the pressure is not high, and it is not afraid of a slight leakage and can cause safety hazards. But if there is vibration and shaking, it is very unreliable.
3. Welding does not need to consider dismantling, or the temperature and pressure have cyclical changes. The flange may cause leakage risk, or the high temperature may cause the flange to loosen or have high-frequency vibration, which may cause the gasket to fail. Lan occasion.
4. Threaded connection, if it refers to low and medium pressure, generally on the kettle body or space is small and can not be unraveled frequently, or the pressure is particularly high, the general gasket has not adapted to the sealing requirements Or the sealing material requirements are too high and too harsh, and the metal lens pad of the same material can be used to solve the problem.
