The sealing strip material is normally similar in composition to the condenser tube material, with specific properties to provide better performance for this application. When the condenser tubes are stainless the sealing strips are normally supplied in a 300 grade stainless steel or a 2205 duplex stainless, with the corresponding bolting in a similar material or Monel. In units with copper alloy tubes, it’s not uncommon to see units in the field with brass sealing strips and accompanying brass hardware.
This concludes our discussion on sealing strips. If you are entering an outage, please make sure to pay attention to your condenser sealing strips if your installation includes them. If you have any questions about sealing strips or you suspect a sealing strip issue, please feel free to contact Graham with any questions or concerns.
