Tube hydraulic expansion is applied in the process of heat exchanger tube bundle manufacturing, such as strength expansion, sticking expansion, pre-welding pre-expansion and post-welding sticking expansion of heat exchanger tube sheet and heat exchange tube, so as to ensure the connection strength and stability of heat exchanger after manufacturing. sealing requirements.
The connection between the heat exchange tube and the tube sheet mainly includes expansion, welding and expansion welding. The expansion methods can be divided into mechanical expansion, hydraulic expansion, rubber expansion and explosion expansion.
