Compliance Notes: Update inspection intervals and thickness calculations; notify responsible design engineers and update procurement specifications.

When industrial equipment like pressure vessels or piping experiences wall thinning, corrosion, or erosion, engineers often use a "patch" to restore integrity. The primary standard for these repairs is ASME PCC-2: Repair of Pressure Equipment and Piping . asme standard patched

For thick walls (e.g., >1.5 inches) or P-Number 4 materials (Chrome-Moly), the patch must be stress-relieved per ASME VIII. asme standard patched
