Are your heat exchanger tubesheets suffering from intergranular corrosion or joint failures due to extreme thermal cycling? Upgrading to titanium-stabilized metallurgy is the definitive solution for severe industrial environments.
Yuhong Group Co., Ltd. engineers and manufactures precision-machined ASTM A182 F316Ti (ASME SA182 F316Ti) forged stainless steel tubesheets. Specifically designed for demanding high-temperature and highly corrosive operations, our tubesheets provide the uncompromising structural anchor your shell and tube heat exchangers require to prevent cross-contamination and guarantee zero-leakage performance.
In welded thermal systems operating between 450°C and 700°C, standard 316L stainless steel can still experience chromium carbide precipitation at the grain boundaries, leading to sensitization and premature weld failure.
ASTM A182 F316Ti solves this industry challenge through Titanium Stabilization (Ti ≥ 5 * (C + N)). The titanium preferentially binds with carbon, preventing intergranular corrosion in the heat-affected zone (HAZ) after welding or prolonged thermal exposure.
Advanced Forged Construction: Our blanks undergo rigorous forging processes to eliminate internal porosity, optimizing mechanical properties in the through-thickness direction—critical for high-pressure tube-to-tubesheet joint integrity.
Ultra-Precision CNC Drilling: Tube holes are drilled to micro-tolerances (typically +0.05 / -0.00 mm) to ensure a flawless fit during mechanical tube rolling or orbital seal welding.
Engineered Expansion Grooves: Integrated annular grooves (2 or 3 per hole) dramatically increase the tube pull-out strength, preventing joint relaxation under severe operational pressure cycling.
Every F316Ti tubesheet we ship features 100% material traceability. Parts are clearly stamped with the heat number, material grade, and inspection stamps as standard practice.

Engineering Rule of Thumb: If your continuous process fluid temperature exceeds 400°C and requires welded tube-to-tubesheet joints, F316Ti is mandatory to safeguard the structural lifespan of the equipment core.
Thanks to its resilience against sensitization and hydrogen attack, F316Ti forgings are widely deployed across critical processing sectors:
Petrochemical & Refining: Hydrogen service heat exchangers, hydrocracker cooling loops, and high-temperature acid heaters.
Power Generation: Heat Recovery Steam Generator (HRSG) intercoolers and high-pressure feedwater preheaters.
Chemical & Pharmaceutical: Corrosive reactor heat exchangers and high-purity, high-temperature steam generators.
To guarantee a 100% precise physical drop-in fit for your replacement tube bundle core, please review this technical checklist before finalizing your specification:
Tube Hole Tolerances: Ensure the hole clearance matches your tube outer diameter (OD) and wall thickness perfectly to avoid over-rolling or loose, leaky expansions.
Baffle & Tie Rod Alignment: Cross-reference your pass-partition plate layouts and bolt circles with original engineering drawings.
Gasket Surface Finish: Specify whether your channels require a smooth, concentric serrated, or spiral serrated finish to secure spiral-wound or metal-jacketed gaskets.
Yuhong Group offers both component-only supply and fully assembled thermal systems. We can deliver your F316Ti tubesheet as a standalone piece or integrated into a full heat exchanger tube bundle:
Heat Exchanger Tubes: Matching ASTM A213 / A312 F316Ti seamless tubes, U-tubes, and extended-surface fin tubes.
Internal Hardware: Machined segmental baffles, tie rods, structural spacers, and shell covers custom-tailored to your engineering data sheets.
