Lap Joint Flanges

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.

Lap joint flange
Standards, Dimensions & Weight

Standards: ANSI, MSS, API, AWWA, DIN, JIS, BS and GB.



There are three different types of stub ends, Type A, B and C. Type A stub ends are machined to fit in a standard lap joint backing flange

We offer stub ends at highly competitive prices.

Lap Joint Stub End – The ‘mated’ pair to a Lap Joint Flange. Stub Ends are Fittings used in place of welded flanges where rotating back up flanges are desired. Stub Ends are typically manufactured by two methods, Type A & Type B and are available in two standard lengths , long (ANSI) or short (MSS) pattern.

Lap Joint Stub End

Using stub ends allows sections of the line to be opened for cleaning, inspection, or quick replacement etc, without the need to re-weld.
