Pressure Vessel Design & Engineering
John Wang Design & Engineering Katy Text, 77494
John Wang, Ph.D., P.E.
Refinery and Chemical Plants Engineering Service Capital project EPC service in pressure vessels &
heat exchangers. Turn around EPC service in replacement of pressure
vessels & heat exchangers. Pressure vessels and heat exchangers design &
engineering. Pressure vessels & heat exchangers re-rating. Stress analysis to pressure vessels and other
equipment. Fitness for Service Assessment (FFS) in level 1, 2,
& 3 per API 579-1/ASME FFS-1.
Fitness for Service Assessments
Level 1, 2 local corrosion FFS and level 3 crack size screening
Level 3 FFS for local corrosion, v-ring weld separation plus location distortion for a 23’-0” ID pressure vessel built in 1943.
Level 3 FFS for a local corrosion around bottom nozzle
Level 3 FFS for a local corrosion across a v-ring
Software for Flange Preloading
Based on ASME PCC-1, a new method developed in the software to calculate the optimized reloading for flanges, especially body flanges, to avoid flange leakage in service.
Pressure Vessel & Heat Exchanger Re-rating
Heat exchanger re-rating per process changes.
Tube sheet cracking and design temperature/pressure de-rating
A vertical pressure vessel re-rating in design pressure/temperature.
A new type LPG trailer design
Pressure Vessel & Heat Exchanger Design
A horizontal pressure vessel design
A reactor design
Shell tube heat exchanger design & replacement
Stress Analysis to Pressure Vessels
Stress analysis to an elbow connection failure to a weldolet.
Stress analysis to a large horizontally supported pressure vessel with vacuum rings.
Stress analysis to Emulsion Treat Fire tubes to head connection.
Pressurized transport cargo TCRN & DOT registration calculation and analysis.
A level 3 FFS assessment for local corrosion on a 24" forged nozzle of heat exchanger in HF service.
Roundness assessment for a vertical pressure vessel with local distortion.
Stress Analysis to Pressure Vessels
Stress contour on shell under critical wind speed and verified per ASME code VIII-2 (K=1.2)
Piping stress analysis of a piping skid.
Sub-frame stress analysis to CSA B620 and 49CFR.
Trailer valve guide impact stress simulation.
Stress contour of vessel clip during lifting weight and verified shell stresses per Appendix 4 of ASME code VIII-2
Twin trailer stress analysis to CSA B620 and 49CFR.
