Blind Flanges – Carbon Steel & Stainless Steel, ½” to 48”, Class PN6 to 1500 LBS

These Blind Flanges are used to close the ends of piping systems and pressure vessels, providing a secure seal and allowing for easy access for inspection, maintenance, or future expansion. Manufactured from robust carbon steel (A105, ASTM A234, SS400) and corrosion-resistant stainless steel (SS304/L, SS316/L), they are compatible with a broad range of applications including oil & gas, petrochemical, power, and water treatment systems. Available in sizes from ½ inch (15 NB) to 48 inches (1200 NB), and pressure classes from PN6 to PN40 and ANSI 150 to 1500 LBS, these flanges meet international standards for durability and dimensional accuracy.
