Missing Floating Tubesheet Calculations
Does your floating tubesheet heat exchanger have complete calculations?
I have been asked many times to check calculations for floating tubesheet heat exchangers only to find some of them missing. The calculation I see most often omitted is from the shell side pressure acting on the internal floating tubesheet components. The external pressure from the shell side often governs over the internal pressure from the tube side so checking this case is critical.
Many Owner/Operators will accept equipment for service without these calculations performed. Please double-check this case in your floating tubesheet heat exchangers.
Simple Gasket Look-Up in COMPRESS
Do you spend too much time looking up Gasket Factor (m) and Gasket Seating Stress Factor (y) values?
Whenever someone asks me to design a custom Appendix 2 or Part 4.16 flange I want to know the m and y factors of the gaskets they intend to use. A lot of times this crucial gasket design information is tough to track down. Thankfully COMPRESS has a great selection of pre-loaded gaskets to choose from including manufactures like Garlock, Flexitalic, Lamons, and Teadit.
Use a manufacturer not listed in COMPRESS? It is easy to add new gaskets to the pre-loaded database.
