Customized Precision Titanium Flat Flange

Description Of Customized Precision Titanium Flat Flange

Customized Precision Titanium Flat Flange is a custom-manufactured pipe flange produced from titanium or titanium alloy to customer-specific drawings and specifications. The flat flange design — also known as a plate flange or flat face flange — features a simple, flat circular plate with a central bore and bolt holes. The sealing surface is a full flat face (FF), which is suitable for low-pressure and moderate-temperature piping systems where a soft gasket is used to ensure a reliable seal.

The manufacturing process begins with titanium blanks (forgings, bar stock, or plate) in grades such as GR1, GR2, GR3, GR4, GR5 (Ti-6Al-4V), GR7, GR9, or GR12. CNC machining is used to turn the flange profile, face, and bore to exact dimensions, ensuring tight tolerances (±0.05mm or better), smooth sealing faces (Ra ≤1.6μm), and consistent quality. The flanges are then drilled, chamfered, and inspected to meet international standards including ASTM B381, ASME B16.5, DIN, EN, and JIS.

Titanium flat flanges offer a unique combination of properties: density of approximately 4.5 g/cm³ (about 60% lighter than steel), excellent corrosion resistance in seawater, chlorides, acids, and alkalis, and good mechanical strength at temperatures up to 600°C (depending on grade). The customized precision aspect ensures that each flange fits perfectly into the customer's piping system, reducing installation time and ensuring reliable performance.

Customized Precision Titanium Flat Flanges are available in sizes from 1/2" to 24" with pressure ratings from Class 150 to Class 2500. They can be supplied with Flat Face (FF) sealing surfaces, and custom dimensions, tolerances, and surface finishes are available upon request. Common applications include chemical processing, petrochemical, marine, offshore, water treatment, and aerospace piping systems.

Usage Precautions and Limitations Of Customized Precision Titanium Flat Flange

• Proper Installation: Titanium flat flanges must be installed by qualified personnel using correct gaskets, bolts, and torque specifications. Improper installation can cause leakage or flange damage.

• Gasket Selection: Use gaskets compatible with titanium and the operating fluid. Flat Face (FF) flanges require full-face gaskets. Avoid gaskets containing graphite or other materials that can cause galvanic corrosion.

• Bolt Material: Use titanium or titanium-compatible bolts to avoid galvanic corrosion. If steel bolts are used, provide insulation or isolation.

• Galvanic Corrosion: Titanium is a noble metal and can cause galvanic corrosion when in contact with less noble metals in the presence of an electrolyte. Provide insulation at dissimilar metal interfaces.

• Hydrogen Embrittlement: Avoid exposure to hydrogen-containing environments at high temperatures, as titanium can absorb hydrogen and become brittle.

• Temperature Limitations: Operating temperature should not exceed 600°C (depending on grade). At higher temperatures, titanium may react with oxygen, nitrogen, and hydrogen.

• Cleaning: Clean flange faces with a soft cloth or mild solvent. Avoid abrasive cleaners that could damage the sealing surface.
