Thanks for response. We had posed this question to vendor about suction side getting exposed to discharge pressure however vendor clarified that there is antisurge system provided. The cases you mentioned only seems possible scenario and i suppose probably during recycling the suction flange...
Additionally, API 610 section 6.3.5 states that in estimating MAWP, 10% margin to be considered on maximum discharge pressure. Do you conclude that:
- maximum discharge pressure referred to by API 610 means the discharge pressure corresponding to the suction system design pressure, or this is up...
For one of the projects recently for Centrifugal compressor, vendor has proposed that suction and interstage nozzles of compressor shall be suitable for stage discharge pressure or settleout pressure which ever is higher. Vendor had taken exception to API 617 requirement of clause 4.6.4.1.1...
