Hello, I'm Assessing a failure in the cyclones of the FCCU Regenerator. It is most likely to be related to high tempeture in the cyclones according to the data gotten from the tempeture intruments and according to the findings (sigma phase was found in the rupture zone). I found the design...

Hello, Where can I find the Appendix 4 & 5 of ASME Sec. VIII div. 2? I have 2007 and 2015 versions and I can´t find those appendix

Hello fellows, Can anyone explain me the differences between ASME Sec. VIII div. 1 and ASME Sec. I?

Hello my friends, I'm new designing relief valves, I want to calculate the set presure of a RV, I have read that it has to be lower than the MAWP but ASME Sec. VIII div. 1, allows an overpressure of 10% (in vessels with only 1 RV, 1.-) In which scenario would I want to set the valve with an...

Hello, I'm very confused about these 2 and I really need your help. Pressure Design: If I got the Presure and Tempeture (Operation) how can I calculate the Pressure Design? and Where I can Find this equation in ASME Sec. VIII. MAWP: In UG-27 (ASME Sec. VIII div. 1) they give this ecuation...

Hello Good morning, I'm having an issue evaluating an alternative for a heat exchanger gasket. They offer me to use a gasket with less width (1/2") than the stablished in the original design (5/8") I have searched on ASME Sec. VIII. div. 1 and there's Table 2-4 but I think it refers to the...

Anyone with experience in the design of Leak sealing Devices, specifically Bolted clamps. Bolted clamps 1.-) I want to know the standard that provies me the formulas to calculate the thickness of the body of this device, the bolt sizes and the minimum thickness of the bolted zone - There are...

CASE 1: I NEED TO CALCULATE THE VALUE OF THE MINIMUM AND MAXIMUM TEST PRESSURE FOR A HYDROSTATIC LEAK TEST FOR A NEW PIPE SYSTEM. THE SERVICE IS GAS NATURAL. SHOULD I USE ASME B-31.3 OR ASME B-31.8? ASME B-31.3 PARA. 345.4.2 MENTION THAT THE MINIMUM VALUE SHALL BE NOT LESS THAN 1 1/2TIMES THE...

Since WRC 297 is intended only for cylindrical nozzles attached to cylindrical shells. How can I evaluate Fin Fan cooler Nozzles' on CAESAR II?

Good Morning, I'm currently specifying some plug valves for HF service. I noticed that the model is Tuffline and after doing some researches I'm still not clear about what the tuffline is/means/do. Do anyone have experience with this model of plug valves?/Can anyone give me some explanations...

Good day, I'm designing a new pipeline system using DEP SHELL piping class for Propane+Propylene service, they recommend to use ASTM A-333. Is there any bad experience using ASTM A-106 Gr. B in this type of service? I'm assuming that ASTM A-333 is recommended due to the cryogenic tempeture of...
