The spectacle blind is a solid circle with a handle, which is used for systems that are normally isolated.
The figure 8 blind plate is shaped like figure 8.
One end is a blind plate and the other end is a throttling ring,
but the diameter is the same as the pipe diameter of the pipeline and does not play a throttling role.
The spectacle blind plate is easy to use.
When isolation is required, the blind plate end shall be used.
When normal operation is required, the throttling ring end shall be used.
At the same time, it can also be used to fill the installation gap of the blind plate on the pipeline.
Another feature is that the identification is obvious and it is easy to identify the installation state.
Tubesheet is to drill holes slightly larger than the outer diameter of the pipe on the circular steel plate.
It is a round steel that plays the role of fixing the pipe and sealing medium in the heat exchanger.
It is a kind of fitting that penetrates and welds the pipe to fix it.
The accuracy of tube sheet processing, especially the pipe hole spacing and pipe diameter tolerance,
perpendicularity and finish, greatly affect the assembly and service performance of the chemical equipment listed above
It is mainly used in
chemical vessels, such as tubular heat exchanger, pressure vessel, boiler, condenser, central air conditioning,
evaporator and seawater desalination. It plays the role of supporting and fixing tubular.
The metal material makes it not only have strong rigidity, but also have great heat conduction performance.
