What are the pressure limits for SPPR?

• A. -10 psig to 50 psig
• B. -8 psig to 55 psig
• C. -5 psig to 60 psig
• D. -7 psig to 57 psig

Answer: (B)

The correct pressure limits for SPPR (Subsequent Pressure Relief) are -8 psig to 55 psig. This range is established based on safety and operational standards that dictate the maximum and minimum safe pressure levels for specific applications within the framework of system integrity and performance. Understanding this range is crucial for operators to ensure that pressure relief systems function effectively during abnormal conditions. Operating outside this specified range could compromise the safety and reliability of the pressure relief mechanism, leading to potential system failures or hazardous situations. The other options do not align with the established safety guidelines for SPPR. Each alternative presents a pressure limit range that either exceeds the maximum allowable pressure or does not adequately meet the minimum pressure requirement needed for safe operation, which is critical for maintaining system safety in practice.
