Comprehensive Numerical Stress Analysis & Flexibility Verification
COREX Engineering provides advanced piping stress analysis services to verify the mechanical integrity, thermal expansion flexibility, and dynamic safety of complex industrial piping networks. Using Hexagon CAESAR II, our specialized stress engineers analyze critical piping lines connected to rotating equipment, high-temperature fired heaters, cryogenic tanks, and relief headers.
Our stress auditing process ensures full adherence to allowable code stresses under sustained (internal pressure and deadweight), thermal expansion, and occasional loading cases (wind, seismic, PSV discharge thrust, and slug flow).
Key Technical Deliverables
Thermal Flexibility & Code Stress Reports
Detailed compliance reports comparing sustained, expansion, and occasional stresses against ASME code limits.
Rotating Equipment Nozzle Loads
Verification of forces and moments on pump nozzles (API 610), compressors (API 617), and steam turbines (NEMA SM23).
Spring Hanger & Snubber Sizing
Selection and specification of variable effort and constant effort spring hangers, rigid struts, and hydraulic snubbers.
Flange Leakage Check (NC 3658 & ASME Sec VIII)
Equivalent pressure and Kellog method checks to ensure critical bolted flange joints remain leak-tight under extreme thermal transients.
Dynamic Shock & Water Hammer Analysis
Time-history and spectrum analysis for sudden valve closure, slug flow excitation, and relief valve reaction forces.
Support Load Summaries for Civil Teams
Comprehensive restraint summary sheets listing 3-axis forces and moments for structural steel and foundation design.
