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
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).
