The document provides instructions for using a Flange BossTM spreader tool to safely open flanges on pipes. Key steps include: 1) Checking that no pressure or materials remain in the line before opening any flanges. 2) Selecting the correct Flange BossTM model for the flange rating size. 3) Loosening bolts and inserting the Flange BossTM into a bolt hole to spread the flanges. 4) Rotating the cam-wedge tool to gradually spread the flanges until the safety stop is reached.
AMS® FLANGE BOSS™ Procedures
- 1. FLANGE BOSS™ SPREADER INSTRUCTIONS
- 2. Follow all plant safety procedures, including permits to open flanges. Check and be certain no pressure exists and process material has been drained before opening flanges. If line pressure exists or process material is present, follow plant safety procedure to remove before opening any flanges.
- 3. Select correct Flange Boss for flange rating. In many situations 2 Flange Boss Spreaders should be used. FBX-150-300 fits 150 lb - 300 lb ANSI flanges from ½” to 24” FBX-400-600 fits 400 lb - 600 lb ANSI flanges from ½” to 24” FBX-900-2500 fits 900 lb - 1500 lb ANSI flanges from ½” to 24” 2500 lb flanges from ½” to 12” including ring joint flanges
