Domestic & Import

Flanges.IO sources pipe flanges from both domestic and international manufacturers to provide our customers with the best combination of quality, availability, and value. We evaluate every supplier against rigorous quality standards regardless of country of origin, ensuring that all flanges meet the applicable ASTM, ASME, and industry specifications.

Domestic flanges are manufactured in the United States and typically carry shorter lead times for custom orders. They are required for projects with Buy American Act (BAA) compliance, ARRA domestic content requirements, or owner specifications that mandate U.S.-manufactured materials. Domestic flanges are forged and machined by ASME-certified facilities with complete material traceability.

Import flanges are sourced from qualified international manufacturers and offer competitive pricing for standard sizes and materials. Our import sources maintain international quality certifications and produce flanges to the same ASTM and ASME standards as domestic mills. All import flanges undergo receiving inspection at our facility, including dimensional verification, material confirmation via PMI, and review of mill test reports before release to customers.
