Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges.
Furthermore, a standard lap joint flange will typically have a longer hub length in comparison to a slip on flange, but this is often considered unnecessary for many applications. Pipe Flanges And Fittings
Ceramic Lined Lateral pipe Wye
Ceramic Lined Lateral pipe Wye from a single spool piece to complete piping systems.
The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face.
