ASME VIII-1 Shell and Tube Heat Exchanger TEMA AHS Floating Head Alloy Cooler
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.

This ASME VIII-1 cooler uses a TEMA AHS floating head layout that separates shell-side and tube-side thermal movement, making it a practical choice for services with wide temperature swings. The combination of an SA516 Grade 485 shell and SA179 cold-drawn seamless tubes delivers strength in the shell and ductility in the tubes, which together resist thermal fatigue in cyclic operation. The removable head and bundle keep inspection and cleaning straightforward, protecting your maintenance budget over the equipment life. Fabricated to ASME Section VIII Div. 1 with CE certification, the unit ships with complete documentation and is supported by our engineering team during installation and startup.
