GR7 Titanium Flange is manufactured from Grade 7 titanium alloy (Ti-0.2Pd) and supplied by TSM Technology, a globally recognized specialty metal materials manufacturer and exporter. Designed for corrosive and high-demand service conditions, this flange delivers outstanding resistance to reducing acids, oxidizing media, and chloride-rich environments, outperforming conventional commercially pure titanium grades in long-term reliability.
Backed by three manufacturing facilities, eight production lines, and over 100 advanced machines, TSM provides GR7 titanium flanges with consistent quality, stable mechanical properties, and strict international quality control. Designed for use in demanding industrial piping and pressure systems, GR7 titanium flanges combine stable mechanical properties with exceptional corrosion protection, delivering a robust connection interface for process lines that encounter strong acids, chlorinated media, or other harsh operating conditions.

Why GR7 Titanium Flange Outperforms Standard Titanium Grades
Titanium Grade 7 (Ti-Pd alloy) is characterized by the addition of palladium, which significantly enhances resistance to:.
Reducing acids and sulfuric acid environments
Chloride stress corrosion cracking
Crevice corrosion and localized attack
High temperature oxidation (compared with many stainless steels)
This alloy maintains good ductility and weldability, allowing GR7 flanges to be fabricated with consistent dimensions and reliable joints in complex piping networks.
Key Features & Engineering Benefits
Enhanced corrosion resilience - Exceptional performance in mixed chemical environments
Uniform material properties - Excellent consistency and structural integrity after welding
Lightweight strength - Lower mass compared to steel counterparts without sacrificing mechanical capacity
Thermal stability - Maintains properties across a broad temperature range
Long service life - Reduced maintenance and replacement costs in corrosive systems
These characteristics make GR7 titanium flanges a preferred material in sectors where fluid composition and environmental exposure are severe.
Typical Industrial Applications
GR7 titanium flanges are widely employed where corrosion performance is critical:
Chemical processing & manufacturing plants - Corrosive liquid transfer, media lines
Petrochemical & refining systems - High chloride, high sulfur environments
Marine & offshore installations - Seawater handling, ballast and cooling circuits
Desalination & water treatment equipment - Brine and aggressive feedwater
Energy & power generation - Corrosion-resistant piping in steam and cooling applications
Industrial gas and fluid lines - Specialty service requiring high dependability
Manufacturing & Quality Assurance
GR7 titanium flanges from TSM Technology are produced using precision forging and CNC machining processes to achieve consistent dimensional tolerances and surface quality. Each flange undergoes rigorous inspection including:
