Description / Abstract:

This International Standard specifies requirements for full peripheral ultrasonic testing of the ends of seamless and welded tubes for the detection of laminar imperfections.

It is intended to detect, over a zone at the ends of plain end and bevelled end tubes, laminar imperfections which may interfere with subsequent fabrication operations (e.g. welding, ultrasonic inspection of welds, etc.).

This International Standard is applicable to the inspection of tubes with an outside diameter greater than 30 mm. No lower limit of thickness is specified, but see note 1.

NOTE 1 For thicknesses less than 5 mm, difficulties can be experienced in detecting laminar imperfections by this method. When such difficulties arise, an agreement between the purchaser and manufacturer is required to determine the testing technique to be adopted.
