Our Coffer flanges are domestically manufactured in grades of carbon steel such as A105/A105N, A350 LF2, and high yield A694 (F42-F70). These flanges are manufactured to ASME B16.5/B16.47 and immediately available from a continually replenished inventory. The Coffer brand has been audited and widely approved on nearly every major approved vendor list. We also offer large-diameter flanges and custom open-die forgings with a quick-turn service available to produce your product as quickly as 48 hours. These high pressure, heavy wall, and large-diameter flanges can be up to 12-in. 2500 psi, 24-in./1500 psi, or 216-in. diameter, and weighing up to 40,000 pounds.
