Slip-On Flanges – Carbon Steel & Stainless Steel, ½” to 48”, PN & ANSI Classes

These Slip-On Flanges are manufactured from premium-grade carbon steel (A105, ASTM A234, SS400) and stainless steel (SS304/L, SS316/L) to deliver reliable flange connections for a broad range of piping systems. Designed for easy slip-on installation, they fit pipes ranging from ½ inch (15 NB) up to 48 inches (1200 NB). The flanges comply with international standards and support a wide range of pressure classes including PN6, PN10, PN16, PN25, PN40 as well as ANSI classes 150, 300, 600, 900, and 1500 lbs, making them ideal for oil & gas, petrochemical, water treatment, and general industrial applications. Their robust construction ensures excellent mechanical strength and resistance to corrosion in demanding environments.
