ASME Calculations

We help customers run ASME calculations of Section VIII pressure vessels, Section I, Section IV boilers and B31.1/31.3/31.5 piping. Towers are analyzed in PVElite based on seismic and wind load conditions on installation site. Tube and shell heat exchangers are calculated to part UHX of ASME Section VIII, Division 1 and TEMA. We also calculate and P. Eng. stamp Section VIII, Division 2 designs. We are experienced in high pressure piping calculations and fatigue analysis.

Design data:
Shell side: Design pressure: 100 psi; design temperature: 212F; mean metal temperature along shell length (assumed): 180F, C.A.: 1/16″.
Tube side: Design pressure: 300 psi; design temperature: 295F; mean metal temperature along tube length (assumed): 248F; C.A.: 1/16″.
This show focuses on how tubesheet is calculated to UHX by PVElite. Therefore, nozzles and supports are not included in the model.

Project #4: Valve to be Calculated by ASME Code

Design conditions:
Design code: ASME Section VIII-1, 2007 ED.
MAWP: 150 psi
Design temperature: 200F
MDMT: -20F
Corrosion allowance: 0
Hydrotest pressure: 195 psi

This design can be calculated by code rules. Valve body is calculated as shell with opening verified by UG-37. End flanges are checked by App. 2. For CRN registration purpose, additional documents submitted are:
