Shell & Tube Heat Exchangers (TEMA)
Thermal and Mechanical Optimized Exchanger Engineering
Optimized shell & tube configurations compliant with TEMA Class R, C, and B standards for maximum heat recovery and low pressure drop.
TEMA Compliant Exchanger Solutions
Heat exchangers directly dictate plant energy efficiency and operational fuel costs.
POLIEN optimizes tube bundle layout, tubesheet thickness, baffle pitch, and shell diameter according to fluid thermodynamic properties.
Key Exchanger Capabilities
Tubesheet Thickness Calculations
Sizing fixed, floating head, and U-tube tubesheets under combined pressure and thermal loads.
Flow-Induced Vibration (FIV) Analysis
Preventing acoustic resonance, fluid-elastic instability, and tube-to-baffle fretting.
Differential Thermal Expansion & Expansion Joints
Calculating shell-to-tube thermal stress differentials and bellows sizing.
Shell & Channel Nozzle Layout
Impingement plate sizing to prevent tube erosion under high-velocity fluid entry.
