We supply both domestic and imported flanges, giving our customers flexibility in cost, lead time, and sourcing preferences—without compromising on quality.
What’s the Difference?
Domestic flanges are manufactured in the USA, often preferred for:
- Buy American Act compliance
- Critical applications (nuclear, military, aerospace, etc.)
- Projects requiring full material traceability and mill test reports (MTRs) from U.S.-based mills
Import flanges are manufactured internationally, often in Europe, Asia, or the Middle East. They’re widely used in commercial, industrial, and energy sectors, especially when:
- Cost efficiency is a priority
- Larger quantities are needed quickly
- Global standards (DIN, EN, JIS, GOST) apply
Quality Control: No Shortcuts
Whether domestic or import, all our flanges go through strict quality inspections:
- Verified to ASTM, ASME, API, or other required standards
- Ultrasonic, hydrostatic, and dimensional testing
- Full documentation provided upon request
We partner only with reputable, ISO-certified mills, ensuring consistent quality regardless of origin.
