Internal Manual Flange Clamp (ISEC) is suitable for clamping flanges to bends. The IMF clamp is a fast and easy tool to use. 
 
ISEC Clamps have a range from 2.25” (56 mm) up to 20.4” (520 mm). 
 
IMF Clamps can be used on all types of materials as only stainless steel comes in contact with the pipe.
