Pressure Seal Valve orders may potentially have misclassified material and non-destructive examination requirements for segment ring designs.
Crane Nuclear 'Classification of Valve Parts', Procedure 03-107, provides guidance for appropriate material and NDE [Non Destructive Test] requirements for processing valve and valve part orders. The procedure is based on the ASME Code Case N-62, which is ASME B&PV Section Ill, 2015 Edition, Non-Mandatory Appendix HH 'Rules for Valve Internal and External Items'.
A pressure seal valve segment ring requires the material to be purchased Safety Related, ASME B&PV Section II, Part D materials, and required NDE (reference Category 3 valve items per N-62). A segment ring may have been processed to material requirements not as pressure retaining material per NX-2000 of the Code resulting in the incorrect material specification and non-destructive examination specified.
