No Threaded Flanges in ASME Division 1 and Division 2 Vessels
I’m fine Replacing-In-Kind, but I’m not going to Replace-In-Kind the threaded flanges from your old pressure vessel and heat exchanger drawings. Spotting threaded flanges in your old drawings signals that it’s a great time for some upgrades.
I understand that it’s tough keeping up with updates to all of the codes and standards required. That’s why I represent Owner/Operators by helping them enforce their own specifications. Specifications without enforcement are just words on a page.
I don’t allow threaded flanges in facilities that use Process Industry Practices (PIP) standards because threaded flanges are not allowed in vessels designed per ASME Code Section VIII Division 1 and 2.
Joint Industry Project 33 (JIP 33) doesn’t allow threaded flanges either.
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.
