M Metal Tubes India Pvt Ltd is a leading manufacturer and global exporter of Slip-On Raised Face (SORF) Flanges made from premium grades of Stainless Steel, Alloy Steel, Duplex, and Copper Nickel. Backed by 40+ years of manufacturing excellence, we supply ANSI-compliant flanges to domestic and international clients in industries like oil & gas, marine, and chemical processing.

What Are Slip-On Flanges?

Slip-On Flanges are designed with a slightly larger bore than the pipe’s outer diameter, allowing them to slip over the pipe for easy alignment and welding. These flanges are ideal for low-pressure and low-temperature applications where quick installation and minimal adjustment are required. The raised face improves sealing efficiency when used with appropriate gaskets, making them leak-resistant and reliable for moderate service conditions.
