Type A Stub end is used with standard lap joint flanges, so it also called lap joint stub end. Its lap thickness is greater than or equal to the thickness of pipe wall. There are two types of stub ends: Short pattern and long pattern. Short pattern also called MSS-A stub end, and long type called ASA-A stub end or ANSI length stub end. The main difference between them is their length.
