Lap joint flanges are one such flange type popular in both piping and duct system design.
What is a Lap joint flange?
Lap Joint flanges are used in a two-part assembly consisting of a Stub End which is butt welded to the pipe and a lap joint flange which is slid onto the pipe before welding the Stub End.

Stud End:
A stub end is always used with a lap joint flange as a backing flange. There are three different types of stub ends, type A, B and C.
Type A stub end can be machined to fit the standard lap joint support flange.
Type B stub end is designed to be used with standard slip on flange.
Either a lap joint flange or slip on flange, the type C stub end can be used
Stub end include long or short pattern length. The end of long pattern is also known as ASA Stub Ends. The short end is used with the larger flanges of ANSI 300 and 600. They are commonly used in most sizes ANSI 900 and above.
Detailed Photos
Lap Joint flanges are very similar to Slip On flanges.But they are not the same.
However, Lap Joint flanges include a radius at the intersection of the flange face that is made to accommodate the flared portion of the Stub End making it only compatible to Stub Ends.
Materials for Lap Joint flanges and Lap Joint Stub Ends vary and may even differ in a single implementation to allow for greater cost flexibility.
