Slip On Flat Face Flange

Slip On Flat Face Flange

A Slip-On Flat Face (SOFF) flange is a type of flange commonly used in piping systems for connecting pipes or fittings. It's referred to as "slip-on" because the flange is slipped over the pipe end and then welded both inside and outside to provide strength and prevent leakage. SOFF flanges are relatively easy to install and are suitable for low-pressure applications where frequent disassembly is not required. They are commonly used in industries such as water treatment, HVAC, plumbing, and low-pressure process piping systems.

However, it's important to note that SOFF flanges may not be suitable for high-pressure or high-temperature applications due to the limitations of the slip-on design. In such cases, weld neck or socket weld flanges with raised faces are preferred for their superior strength and reliability.

SOFF flanges are available in various sizes, materials, and pressure ratings to suit different piping system requirements. Proper installation and welding procedures are essential to ensure a secure and leak-tight connection with SOFF flanges.
