Source Slip On Flange from verified mills, manufacturers and stockists on MetalMitra. Options span all standard face types and pressure classes, and every order can ship with an EN 10204 3.1 certificate.
Slip On Flanges are designed to slide over the outside diameter of a pipe before being welded in position. Their practical installation design makes them suitable for a broad range of process piping, fabrication and engineering applications.
Slip On Flanges are widely used flange components designed to connect pipes, valves, equipment and other piping components. The flange is positioned over the pipe and then welded to create a secure piping connection.
