At Proffinox, quality is not a final checkpoint—it is an engineering discipline integrated into every stage of production, from raw material receipt and plate cutting to final passivation and factory acceptance testing (FAT). Our dedicated Quality Assurance Department conducts rigorous partial inspections during fabrication as well as comprehensive final release testing. We perform certified Non-Destructive Testing (NDT) tailored to the specific operational, hygienic, and pressure demands of each customer and industry. Backed by ASME U and R Stamps, National Board registration, ISO 9001:2015 certification, and AWS D1.6 compliance, our vessels provide full material traceability and document transparency.
