Manufacturing Failures

------------------------------------------------------------------------------------

An ASTM A 234, Grade WPB, carbon steel 8 inch standard wall long radius 90degree elbow was submitted for a cause of failure analysis when it was found to be leaking after being placed in service.

The leak had taken place through a crack on the inner radius of the elbow.

Metallurgical examination had shownthat the crack in the bend was caused by a material defect, a sizable slag inclusion on the inside radius of the bend.
