Titanium Flanges
Titanium flanges are highly durable and corrosion-resistant piping components widely used across industries that demand strength, reliability, and long service life. Manufactured from premium titanium alloys such as Grade 2 (Commercially Pure Titanium) and Grade 5 (Ti-6Al-4V), these flanges provide outstanding mechanical strength while remaining significantly lighter than many traditional materials like steel and nickel alloys.
Designed to connect pipes, valves, pumps, and other equipment, titanium flanges form a strong, leak-proof seal even under high pressure and extreme temperatures. Their unique combination of lightweight efficiency, superior corrosion resistance, and high tensile strength makes them an ideal choice for industries such as aerospace, marine, oil & gas, power generation, chemical processing, and desalination.
Chemical Composition of Titanium Flanges
The excellent properties of titanium flanges are determined by their alloy compositions:
Titanium Grade 2 (Commercially Pure Titanium)
Ti: 99.2% min
C: 0.1% max
Fe: 0.3% max
H: 0.015% max
N: 0.03% max
O: 0.25% max
Grade 2 is known for its exceptional corrosion resistance, particularly in oxidizing and mildly reducing environments. It is easy to fabricate and weld, making it a preferred material for seawater systems, chemical processing equipment, and heat exchangers.
Titanium Grade 5 (Ti-6Al-4V)
Ti: 90% min
Fe: 0.25% max
O: 0.2% max
Al: 6% min
V: 4% min
Grade 5, also called Ti-6Al-4V, is the most widely used titanium alloy. It offers high strength, excellent fatigue resistance, and toughness, making it ideal for aerospace structures, offshore engineering, and high-pressure applications.
Mechanical Properties of Titanium Flanges
Titanium Grade 2
Density: 4.5 g/cm³
Melting Point: 1665 °C (3030 °F)
Tensile Strength: 344 MPa (49,900 psi)
Yield Strength: 275 MPa (39,900 psi)
Elongation: 20%
Titanium Grade 5
Density: 4.43 g/cm³
Melting Point: 1632 °C (2970 °F)
Tensile Strength: 950 MPa (138,000 psi)
Yield Strength: 880 MPa (128,000 psi)
Elongation: 14%
These mechanical values demonstrate the balance between strength and ductility. Grade 2 provides flexibility and superior resistance to corrosion, while Grade 5 offers maximum mechanical performance for more demanding environments.
Key Benefits of Titanium Flanges
Corrosion Resistance – Performs exceptionally well in seawater, chlorides, and aggressive chemicals.
High Strength-to-Weight Ratio – Stronger than many steels but about 40% lighter.
Durability in Harsh Environments – Resists erosion, pitting, and stress cracking.
Biocompatibility – Non-toxic and safe for medical and pharmaceutical applications.
Wide Temperature Range – Suitable for both cryogenic applications and elevated temperatures.
Cost Efficiency Over Time – Longer service life reduces downtime and replacement costs.
Types of Titanium Flanges
Titanium flanges are available in various designs to suit different industrial requirements:
Weld Neck Flanges – Ideal for high-pressure systems, offering excellent stress distribution.
Slip-On Flanges – Easy to install and widely used in low-pressure applications.
