ASME tanks must meet rigorous design criteria to ensure structural integrity and operational safety. Key factors include:
Material Selection
Common materials include carbon steel, stainless steel, and alloys (e.g., Hastelloy, Inconel).
Material selection depends on factors such as pressure, temperature, and corrosion resistance.
Pressure and Temperature Ratings
ASME Section VIII defines design pressure limits for different tank classifications (Divisions 1, 2, and 3).
Temperature considerations affect material strength and weld integrity.
Welding and Fabrication Standards
ASME-certified welders must follow Section IX for welding procedures.
Non-destructive testing (NDT) methods (e.g., radiography, ultrasonic testing) ensure weld quality.
Nozzles, Supports, and Accessories
Proper reinforcement around openings (nozzles, manways) is critical.
Supports (saddles, legs, skirts) must withstand static and dynamic loads.
