Required information to complete stress analysis
Pump type (API/ANSI) etc:
GA Drawing of pump showing support location, nozzle distance from centreline, vendor allowable loads
Temperature info (usually from line list and P&ID)
Material of the pump (usually on the GA and datasheet)
ANSI flange size (150#, 300#, etc - usually on the GA or detailed drawings)
Nozzle movements from equipment zero point (point of zero thermal growth) especially important for high temperature equipment
- This information is used for both the 3D model and the stress model.
Other types of equipment:
- Complicated equipment like centrifugal compressors, heaters and reactors require more information from vendors like growth calculations, skin temperatures and layout of piping within the equipment
- Reciprocating compressors often require acoustic analysis to see how the vibrations of the equipment affect the piping. See API 618 (Section 7.9.4.2 and Annex N).
