How to choose equipment flanges
Thread Content
For fixed-tube-sheet heat exchangers, the shell side value is 1.0 and the tube side value is 0.6; according to JB/T4701, should the flange size for the tube box be 0.6 or 1.0?
If the design pressure for the pipe fitting is 0.6, it depends on the material and operating temperature; check the pressure-temperature rating table for the equipment’s flange standards to determine whether it should be 0.6 or 1.0
By the way, this post should be posted in the heat exchange equipment technical discussion forum, so there will be more people who can respond
The pressure rating is determined according to the temperature rating table; for higher temperatures, JB/T4703 should be used as a guide for selection
O(∩_∩)O~ Got it O(∩_∩)O Thank you
The tube box flange is mainly used for the tube side, and the pressure is then determined based on the temperature
For high pressure, choose 1.0
