A surface finish of Ra 0.4-0.8 μm is typically required to ensure proper sealing without excessive deformation. Finer finishes may reduce sealing effectiveness, while rougher surfaces increase leak paths.
Visual inspection should occur during every maintenance shutdown (typically 12-24 months), with dimensional verification every 3-5 years depending on service conditions and cycle frequency.
Minor scratches (<0.1 mm depth) can often be polished out, but significant damage requires re-machining or replacement. Weld repair is generally not recommended due to distortion risks.
