  • Tighten bolts gradually and evenly to the recommended torque values. Over-tightening can damage the flange or gasket, while under-tightening can result in leaks.

8. Gasket Installation:

  • Place the gasket carefully between the flange faces, ensuring proper alignment. Avoid over-compressing or twisting the gasket during installation.

9. Bolt Tightening Sequence:

  • Follow the specified bolt tightening sequence for the flange type (e.g., star pattern or circular pattern) to ensure uniform compression of the gasket.

10. Inspection After Tightening:
– After tightening the bolts, inspect the flange joint for any visible gaps or misalignment. If issues are detected, address them immediately.

11. Pressure Testing:
– Conduct a pressure test, if required, to check for leaks and ensure the integrity of the flange joint. Follow industry-standard procedures for pressure testing.

12. Documentation:
– Maintain comprehensive records of the installation, including torque values, pressure test results, and any deviations from the recommended procedures.

13. Retightening:
– In some cases, it may be necessary to perform a retightening of the bolts after the initial installation or after the system has been subjected to pressure and temperature changes. Follow the manufacturer’s guidelines for retightening.

14. Periodic Inspections:
– Implement a regular inspection and maintenance schedule to check for signs of wear, corrosion, or degradation of the flanges, gaskets, and bolts. Replace any components that show signs of deterioration.

15. Training and Expertise:
– Ensure that personnel responsible for flange installation are adequately trained and possess the necessary expertise in high-pressure system maintenance and safety.

Proper installation of Class 600 flanges is essential for the long-term performance and safety of high-pressure systems.
