Pressure Equipment Design & Analysis
Mechanical Sizing Compliant with ASME Section VIII Div. 1/Div. 2 and EN 13445
Analytical and numerical calculations for shells, dished heads, flanges, and nozzle connections under internal and external pressure.
Pressure Vessel Engineering
Because pressure vessels contain hazardous fluids under high energy, their design demands zero-error discipline.
POLIEN precisely verifies elastic and plastic stability boundaries under design pressure (Pn), test pressure, and external vacuum loads.
Technical Sizing Disciplines
Shell & Head Sizing
Minimum wall thickness determination for cylindrical shells, elliptical, and torispherical heads.
Nozzle Reinforcement & WRC Stress Analysis
Nozzle neck local stresses and pad reinforcement under piping loads.
Flange & Bolting Sizing
Flange sealing and gasket seating calculations per ASME App. 2 and EN 13445-3.
External Pressure & Vacuum Stability
Stiffener ring placement and shell buckling resistance verification.
