SHORT/LONG PATTERN STUB ENDS (ASA/MSS)
Stub ends are available in two different patterns:
- the short pattern, called MSS-A stub ends
- the long pattern, called ASA-A stub ends (or ANSI length stub end)
STUB END TYPES
Stub ends are available in three different types, named “Type A”, “Type B” and “Type C”:
- The first type (A) is manufactured and machined to match standard lap joint backing flange (the two products have to be used in combination). The mating surfaces have an identical profile to permit a smooth loading of the flare face
- Stub ends type B are have to be used with standard slip-on flanges
- Type C stub ends can be used either with lap joint or slip-on flanges and are manufactured from pipes
BENEFITS OF LAP JOINT STUB ENDS
Essentially, stub ends allow to minimize the weight of high-grade material in stainless, duplex, and nickel alloy piping, saving costs. Of course, the bigger the diameter and the class of the flanges, the higher the saving!
2.Facilitates the installation of the flange
The lap joint flange can be rotated on the pipe and simplify the alignment of the bolt holes of the mating flanges
It shall be noted that stud ends are becoming popular also in high-pressure applications (whereas they were used for low-pressure applications only in the past).

1.Reduces the overall cost of the flanged joint
Generally, the lap joint flange is of a lower grade than the material of the stub end and the pipework, thus saving the total weight of high-grade material used for the flanged joint.
Example:
For an SS316 pipe, instead of using a full 316 welding neck flange, a combination of an SS316 stub end and a carbon steel lap joint flange would do the same exact job, but the total weight of SS316 material would be lower, and the cost as well.
Essentially, stub ends allow to minimize the weight of high-grade material in stainless, duplex, and nickel alloy piping, saving costs. Of course, the bigger the diameter and the class of the flanges, the higher the saving!
