Tube-Mac - Flared Flanges

The Flare Flange connection consists of pipe suitable for cold forming (reference pages B6-B7), flare flanges, flare cones with elastomer seals and bolting hardware.

Step 1: Cut pipe end square, deburr and clean. Slip flange onto the pipe before flaring. Place pipe into the flaring machine with the correct dies and flaring cone to suit the pipe size.	Step 2: Pipe is to protrude to the stop on the die. Lubricate the flaring cone, start the machine, flare the pipe end until fully formed against the die. Stop the machine, remove the pipe from the die.
Step 3: Clean and visually inspect the flare. The surface of the flare should be smooth and free of any defects.	Step 4: Select the correct pipe cone style (ref. pgs. B4-B5). Insert pipe cone into the flared end of the pipe (use rubber hammer if required).
Step 5: Select the required bolting hardware from section Section R of this catalogue.	Step 6: Tighten bolts to the torque values specified. Always tighten bolts in a cross-over sequence and ensure that the flanges are parallel.
