Plate Flanges – Carbon Steel & Stainless Steel, ½” to 48”, JIS 5K/10K/16K & PN10/16

These Plate Flanges are precision-manufactured from high-quality carbon steel (A105, ASTM A234, SS400) and stainless steel (SS304/L, SS316/L) materials to provide durable, corrosion-resistant flange connections for industrial piping systems. Suitable for sizes ranging from ½ inch (15 NB) up to 48 inches (1200 NB), these flanges comply with multiple international standards, including JIS (5K, 10K, 16K) and PN (PN10, PN16) pressure classes, making them versatile for various applications in chemical processing, water treatment, oil & gas, and general industrial use. The robust design and precision engineering ensure leak-tight sealing and long-term service life in demanding environments.
