TM6613 Titanium (Ti) Stub Ends

Titanium Stub Ends Description

Titanium Stub Ends are a key component in pipe fitting systems, providing excellent performance across various industrial applications, particularly in chemical processing. These fittings, made from Grade 2 Titanium, are significantly lighter than steel while offering superior corrosion resistance. Titanium Stub Ends comply with the dimensional tolerances outlined in ASME B16.9, ensuring reliable and accurate performance.

These fittings are employed to connect pipes with flange connections, facilitating a secure and tight joint. Additionally, the flange is formed using a method known as "flanging." This process shapes a part of the tube to create a flange with a specific angle or wall thickness, optimising the strength and durability of the fitting. Titanium Stub Ends are ideal for environments with high corrosion risk, extending the lifespan of piping systems while simultaneously reducing maintenance costs.

• Performance Features of Titanium Pipe Fittings

• Exceptional corrosion resistance

Titanium pipe fittings exhibit high corrosion resistance under various harsh conditions. This is because Titanium quickly forms a dense and stable oxide layer (TiO₂) upon contact with air or oxidising substances. This oxide barrier prevents exposure of the material to further corrosive elements, providing built-in protection for the material. In industries such as chemical processing, Titanium fittings withstand aggressive acids like concentrated sulphuric and nitric acid, as well as highly corrosive substances like seawater and brine. This enables reliable long-term transport of corrosive liquids and reduces the need for frequent maintenance or replacement of components.

• High strength and notable toughness

Titanium pipe fittings are known for their remarkable strength, which ranges between 300 MPa and over 1 000 MPa depending on the alloy grade and manufacturing process. In addition to their strength, these fittings also exhibit excellent toughness, allowing them to absorb pressure, shocks, and vibrations without breaking under load. This combination of strength and durability guarantees reliable performance even under high-pressure conditions and external forces, making them ideal for demanding applications such as chemical high-pressure systems and marine engineering.

• Temperature resistance

Titanium has a high melting point of approximately 1 668 °C, ensuring stable performance across a wide temperature range. Although strength may decline at elevated temperatures, Titanium pipe fittings retain their integrity and strength at moderately high temperatures (e.g. 300-400 °C), making them suitable for heat exchange applications in the medium temperature range. Furthermore, Titanium performs excellently in cryogenic environments, such as in liquefied gas transport systems, where it remains solid and does not become brittle, ensuring safe operation at low temperatures.

• Excellent biocompatibility

Due to their excellent biocompatibility, Titanium pipe fittings are extensively used in medical applications. Titanium causes only minimal immune reactions in the human body, making it an ideal material for medical systems such as artificial blood vessels and dialysis devices. It interacts seamlessly with human tissues and fluids, causing no inflammation or adverse reactions, thereby ensuring safety and efficacy in medical use.

• Lightweight properties

With a density of approximately 4.51 g/cm³, Titanium is significantly lighter than many commonly used metals such as steel and Copper. This lightweight feature makes Titanium pipe fittings highly advantageous in industries such as aerospace and automotive, where reducing weight is crucial. Thus, the use of Titanium fittings in aircraft fuel and hydraulic systems helps to decrease the overall weight of the aircraft, reducing fuel consumption and enhancing handling characteristics.
