Is ASTM A105 Class 150# flange in the non-normalized is acceptable to NACE MR0175?

Viewed 4745 Times

Question: Would a forged ASTM A105 Class 150# flange in the non-normalized condition be in accordance with NACE MR0175 and NACE MR0103?

Answer:

The ISO 15156 Maintenance Panel can only answer for NACE MR0175/ISO 15156, not for NACE MR0103.
AS FORGED is not an acceptable condition in A.2.1.2. Both requirements of A.2.1.2. and A.2.1.3 of Part 2 must be fulfilled for ASTM A 105 flanges to meet NACE MR0175/ISO 15156.

This question is in relation to NACE MR0175/ISO 15156-2 Annex A.2.1.2

Reference: ISO 15156 Maintenance Panel Inquiry #2009-08
