ASTM A234 WP22 Alloy Steel Pipe Fittings
These buttweld pipe fittings offer exceptional performance as they are developed to meet the demands and requirement of customers. On the other hand, to check the quality and finishing of these fittings different tests are done that include:
• Flaring test
• Flattening test
• Ultrasonic test
• Macro and micro test
• Mechanical test
• Third party inspection
• Visual analysis
• Chemical composition analysis
Stub End Types
- Type A stub end: Used with lap joint flanges The lap thickness on the stub end is greater than or equal to the nominal thickness of pipe’s. Lap Joint Stub End usually has a machined serrated face.
- Type B stub end: Used with slip on flanges. The inner corner is square. It also has a machined serrated face.
- C Type : Used for both lap joint flanges and slip on flanges. Its thickness is 75% of the pipe wall. Type C stub end is very short to accommodate backup flanges
Type A, B and C stub end all have short pattern and long pattern, the differences between short pattern stub ends and long pattern stub ends are
- Short pattern: MSS-A stub end.
- Long pattern stub end: ASA-A stub end or ANSI length stub end.
