| High Light | F316Ti stainless steel tubesheet ，high-temperature heat exchanger tubesheet ，titanium-stabilized stainless steel sheet | ||
The SA182 F316Ti tube sheet is a forged stainless steel component designed for shell-and-tube heat exchangers operating in high-temperature and corrosive environments. Manufactured to ASTM A182 / ASME SA182 F316Ti (UNS S31635), this titanium-stabilized austenitic stainless steel tube sheet resists intergranular corrosion—a failure mode that occurs when standard 316L experiences chromium carbide precipitation at grain boundaries during welding or prolonged thermal exposure above 450°C.
The tube sheet serves three critical functions: it provides structural support for the tube bundle, separates shell-side and tube-side fluid streams, and maintains tube alignment under thermal and mechanical loading.

Titanium Stabilization: Ti ≥ 5 × (C + N). Titanium preferentially binds with carbon to prevent chromium carbide formation in the heat-affected zone during welding.
Dimensions: Custom forged tube sheets available up to 8,000 mm outer diameter. Thickness and hole pattern engineered per client specifications. Tube hole drilling tolerance: +0.05 / -0.00 mm. Surface finishes: Raised Face (RF), Flat Face (FF), Ring Type Joint (RTJ).
All SA182 F316Ti tube sheets undergo 100% material traceability with heat number stamping. Standard non-destructive testing (NDT) per ASME Section V:
| Test Method | Application |
|---|---|
| Ultrasonic Testing (UT) | Volumetric examination for internal discontinuities |
| Liquid Penetrant Testing (PT) | Surface crack detection |
| Positive Material Identification (PMI) | Alloy verification |
| Dimensional Inspection | Hole diameter, position, and groove verification |
Additional testing available upon request: radiographic examination (RT), hardness testing, and hydrostatic testing.
SA182 F316Ti tube sheets are specified for heat exchangers, condensers, and pressure vessels in:
Operating Range: Continuous service from -196°C to 700°C. The titanium-stabilized microstructure maintains sensitization-free performance up to 700°C.
Why Forged F316Ti Over Standard 316L?
At temperatures above 450°C, standard 316L undergoes sensitization—chromium carbide precipitation at grain boundaries—leading to intergranular corrosion and premature weld failure. SA182 F316Ti eliminates this risk through titanium stabilization, making it suitable for welded assemblies and long-term high-temperature service.
Forging Process Benefits: Rigorous forging eliminates internal porosity and optimizes mechanical properties in the through-thickness direction—critical for high-pressure tube-to-tubesheet joint integrity.
CNC Precision Drilling: Tube holes are machined to micro-tolerances (+0.05 / -0.00 mm) to ensure flawless fit during mechanical tube rolling or orbital seal welding.
Engineered Expansion Grooves: Integrated annular grooves (2 or 3 per hole) increase tube pull-out strength and prevent joint relaxation under pressure cycling.
