| Step | Action |
|---|---|
| 1. Shut off system | Depressurize and isolate the pipeline. |
| 2. Prepare flange | Clean and inspect the spectacle blind flange and pipe. |
| 3. Align flanges | Position the spectacle blind with "blind" side facing flow. |
| 4. Insert bolts | Align and hand-tighten bolts through flange holes. |
| 5. Tighten bolts | Torque bolts evenly in a criss-cross pattern. |
| 6. Check for leaks | Gradually pressurize the pipeline and check for leaks. |
| 7. Final inspection | Ensure secure and proper installation. |
