Installation | Flexible Pipe Nipples
Bulletin 8777 Page 4
When used to connect misaligned pipes, the nipple should be approximately bent to the required shape before installation to avoid stress on burners or piping when unions or flanges are tightened. All movement, bend limitations, and minimum bend radii listed in the Performance Section should be respected. 8777 flexible nipples are not intended to be compressed or stretched during installation. If the nipple dœs not fit, adjust piping. Only wrench on the proper nipple area. Do not create sharp bends. Bend the corrugated section as close to the center as possible. Do not apply torsion.
