Design pressure of equipment and pipelines
Thread Content
Do the design pressures on both sides of a shell-and-tube heat exchanger need to be exactly the same as those of the connected pipes? For example, if the design pressure on the shell side is 1.0 MPa and the design pressure of the connected pipes is 0.8 MPa, is that acceptable?
The designed pressures of the connected pipelines vary; when in use, they can only be operated according to the lower pressure level. Generally, pipes can withstand higher pressures than containers
The design pressure on the shell side can be increased artificially; as long as it is 0.8 MPa, it will meet the requirements specified in the design
It depends on your operating pressure; the design pressure is merely information related to operating conditions and service life, etc.
