This two-page manufacturing quality plan outlines the quality checks for manufacturing MS pipe fittings. It lists the component or operation, characteristics to check, acceptance criteria, and review process. Raw materials will be checked for chemical and mechanical properties against tender specifications. Finished fittings will be inspected for surface defects, dimensions, and leak proof testing based on drawings and standards. Galvanized fittings will have additional checks for zinc coating uniformity, thickness, and adhesion. NTPC or an authorized representative must witness calibrated equipment and tests. Acceptance norms are derived from NTPC drawings first or other standards and specifications.
