Acceptable Quality with Minor Surface Issues Resolved
Decent product overall with some initial concerns that were addressed. We ordered 7 tons of 304 welded pipe (3" Schedule 10S, BA finish) for clean utility systems. Upon receipt inspection, we found approximately 15% of pieces had minor surface scratches on the BA finish that didn't meet our Ra < 0.4 μm specification for pharmaceutical-grade applications. Contacted supplier immediately with photographic documentation and surface roughness measurements. Their quality team responded within 48 hours, acknowledged the issue, and offered three solutions: full replacement, partial credit, or re-polishing at their facility. We chose replacement for affected pieces which arrived within 12 days at no additional cost. Replacement batch was flawless with Ra values averaging 0.32 μm. Chemical composition and mechanical properties met ASTM A312 requirements throughout. Would suggest they implement stricter final inspection protocols for BA finish products to catch such issues before shipment. Material performance in service has been satisfactory for our potable water systems.
