Regarding the service pressure of the tube sheet at design pressure
Thread Content
I would like to ask the experts: when the design pressure for the tube side of the heating element in a heat network is 2.5 MPa gauge pressure, and its structure is a horizontal U-tube fully welded type, should the gasket plate be designed based on a pressure of 2.5 MPa as per the equipment flanges, or should 6.3 MPa be used?
What is the design temperature? The tube sheet can refer to the equipment flange at 4.0 MPa.
Sorry, I made a mistake; it’s 4.0 MPa. The design temperature for the tube side is 130°C, and that for the shell side is 270°C℃
With such high temperatures, the issue of temperature difference compensation should be considered
