SORF stands for Slip-On Raised Face. A SORF flange is a slip-on flange with a raised face on the gasket seating side. The flange slips over the pipe and is normally fillet welded to the pipe.

The raised-face configuration provides a defined gasket seating surface. SORF flanges are commonly used in industrial piping systems where the selected flange design, pressure rating, material, and installation method meet the engineering requirements of the application.

What Is Monel K500?

Monel K500, also known as Alloy K500, is a nickel-copper alloy identified by UNS N05500. It is a precipitation-hardenable alloy developed to provide higher mechanical strength and hardness than Monel 400 in suitable heat-treated and aged conditions.

The principal alloying elements include nickel and copper, together with aluminum and titanium additions. The aluminum and titanium are important to the precipitation-hardening mechanism. This combination gives Monel K500 a useful balance of corrosion resistance and mechanical strength for selected industrial applications.
