ASME VIII-1 Certified Floating Head Heat Exchanger | TEMA AHS Type, Corrosion-Resistant Alloy Construction
YUHONG ASME VIII-1 Certified Floating Head Heat Exchanger (TEMA AHS Type) combines SA516 Grade.485 carbon steel shell with SA179 cold-drawn seamless tubes to deliver unmatched performance in corrosive and thermally cyclic environments:
SA516 Gr.485 Advantages:
High Strength & Weldability: Carbon-manganese steel plate ideal for pressure vessels (shell/head), offering excellent structural integrity and ease of fabrication.
Low-Temperature Toughness: Normalized + Fine Grain Practice (FGP) ensures impact resistance in harsh operating conditions.
SA179 Advantages:
Superior Thermal Conductivity: Seamless low-carbon steel tubes optimize heat transfer efficiency in exchangers.
Corrosion & Scaling Resistance: Smooth surface finish minimizes fouling, ideal for steam/condenser applications.
