Flange-O-Let

WorldWide Machining & Welding, Inc., has developed a single-bodied FOL (Flange-O-Let) Fitting with integral reinforcement.

This NEW single-body design reduces the number of welds required during the manufacturing process. The elimination of the weld between the main body and the weld-o-let reduces manufacturing costs and increases the overall strength of the FOL.

Field Application

FOL Fittings differ from a TORF (Thread-O-Ring, Flanged) Fitting, as FOLs do not contain internal threading, an aluminum bronze plug, a Viton o-ring or a Teflon o-ring backer.

FOL Fittings were developed with the intention that they be used in the place of a standard weld-o-let and flange combination, commonly used in the pipeline industry.

FOL Fittings are fully compatible with current hot tapping machines.
