Excuse me, what is the difference between metal soft connection and rubber soft connection in HVAC? What are they used for, the main pump or the equipment? How to connect?
Generally, the metal software is relatively small, such as the one on the fan coil, and the one with a larger diameter is connected with rubber soft, which is cheaper. Generally, equipment with vibration should be connected flexibly to reduce vibration! The connection mode is generally determined according to the pipe diameter! For metal thread buckles below DN50, rubber is generally a flange! !
