ASTM B363 Grade 12 Titanium Fittings Manufacturer & Supplier
Corrosion Resistant ASTM B363 Grade 12 Titanium Fittings are the industrial pipeline fittings made from Titanium Grade 12 (UNS R53400). This Ti alloy, being alloyed with Ni and Mo, is commonly used in many applications for chemical processing industries, marine engineering, desalination plants, offshore platforms, power generation plants and heat exchangers due to its superior resistance to pitting, crevice corrosion and other chloride contained media. ASTM B363 refers to the standard requirements for Titanium and Titanium Alloy Seamless and Welded fittings like elbows, tees, reducers, caps and stub ends.
Engineered For Corrosion Resistance In Hostile Process Industries
As a pipe is intended for an extremely corrosive environment, fitting must be able to ensure the service life. Titanium Grade 12 Fittings are one of the most popular materials chosen for superior corrosion resistance and high strength in addition to good weldability.
Our ASTM B363 Fittings come in a full range of sizes, schedules and configuration for the industries of chemical processing plants, marine applications, offshore installations, desalination systems, power plants and industrial fluid handling networks throughout the world. All of our fittings are made according to the ASTM B363 standard with thorough quality inspection in accordance with the required dimensions, structural integrity and reliable performance in corrosive environment.
What is ASTM B363 Grade 12 Titanium Fittings?
ASTM B363 Titanium Fittings are the buttwelding pipe fittings manufactured from commercially pure titanium alloy. Among these types of grades, Titanium Grade 12 (UNS R53400) has one of the best combinations of corrosion resistance and mechanical properties and fabricated ability. The small amount of nickel and molybdenum added in Grade 12 Titanium alloy enhances its resistance towards reducing acids and chloride bearing environments more compared to the pure titanium grade alloys.
These fittings are commonly used for:
- High-purity process piping
- Chemical transportation systems
- Heat exchanger networks
- Seawater applications
- Offshore platforms
- Desalination facilities
- Industrial wastewater systems
Advantages of ASTM B363 Grade 12 Titanium Fittings
- Exceptional Corrosion Resistance: Performs exceptionally well in seawater, chloride-rich environments, and many acidic media.
- Enhanced Strength: Nickel and molybdenum additions improve mechanical properties compared to commercially pure titanium grades.
- Excellent Weldability: Can be fabricated and welded with proper shielding techniques while maintaining corrosion resistance.
- Long Service Life: Provides outstanding durability in aggressive industrial conditions.
- Lightweight Material: Offers a superior strength-to-weight ratio compared to many traditional alloys.
- Reduced Maintenance Costs: Long-term reliability minimizes replacement frequency and operational downtime.
