Titanium flange connection and installation requirements

The connection and installation of titanium flanges require careful attention to ensure proper performance and reliability in the piping system. Here are some key requirements:

1. Flange Facing: Ensure that the flange facing is flat, smooth, and free from any defects or irregularities. The flange faces should be aligned properly to ensure a leak-tight seal.

2. Gasket Selection: Choose an appropriate gasket material compatible with titanium and suitable for the operating conditions, such as temperature, pressure, and fluid compatibility. Common gasket materials for titanium flanges include graphite, PTFE, and spiral wound metallic gaskets.

3. Bolt Tightening: Use the correct type, size, and grade of bolts and nuts for the flange connection. Follow the specified torque values and tightening sequence recommended by the flange manufacturer to ensure uniform bolt loading and prevent over-tightening or under-tightening.

4. Flange Alignment: Align the flanges properly before tightening the bolts to avoid misalignment or distortion, which can lead to leaks or stress concentration.

5. Flange Orientation: Ensure that the flanges are oriented correctly with respect to the piping system, especially for weld neck flanges, which have a raised face that should be positioned facing outward.

6. Flange Inspection: Inspect the flanges and gasket seating surfaces for any damage, corrosion, or foreign particles that could affect the sealing integrity. Clean the flange faces thoroughly before assembly.

7. Bolt Stretching: Use a calibrated torque wrench or tensioning equipment to achieve the specified bolt preload or tension, which helps maintain the integrity of the flange joint under operating conditions.

8. Flange Protection: Apply appropriate corrosion protection measures, such as coatings or sacrificial anodes, to prevent galvanic corrosion between the titanium flange and other metallic components in the system.

9. Post-Installation Inspection: After installation, conduct a visual inspection and pressure test of the flange joint to verify its integrity and leak-tightness before putting the system into service.

By following these connection and installation requirements, you can ensure the proper assembly and performance of titanium flanges in your piping system, minimizing the risk of leaks, corrosion, and mechanical failure.
