Product Description
ASME SB861 19.05×1mm Grade 1 Seamless Titanium U Tube for Heat Exchanger Applications
Product Overview
19.05 ×1mm ASME SB861 Grade 1 Titanium Seamless U-Tube
Engineered for critical heat transfer applications, this U-tube combines the unmatched corrosion resistance of commercially pure titanium with precision manufacturing.
Key Features
- Premium Material: ASTM/ASME SB861 Grade 1 Titanium offers the best ductility and superior corrosion resistance in oxidizing environments (ideal for seawater and chlorides).
- Precision Dimensions: Strict 19.05mm OD × 1.0mm WT tolerances ensure perfect fit and optimal flow dynamics in shell-and-tube exchangers.
- U-Bend Integrity: Mandrel-bent with controlled radii to prevent wall thinning. Stress relieved to prevent stress corrosion cracking.
- Certified Quality: Compliant with ASME Boiler and Pressure Vessel Code requirements, ensuring safety for high-pressure and high-temperature systems.
Applications
Coastal power plant condensers, marine HVAC systems, chemical processing coolers, and pharmaceutical heat exchangers.
