Flat Face Flanges Manufacturers, Supplier and Exporter in India

A flat carbon steel flange is called FF for short. This welding neck flange is a component that has been machined to be flat and therefore does not have a bead-like structure as seen in raised face flanges or ring joints. The flat surface of the welding socket flange allows the gasket to make full contact with the entire surface of the mating material. The flat surface design was developed for the sole purpose of eliminating the bending movement that acts on the flange when the bolts are tightened. When using flanges made of cast iron or fiberglass material, this bending movement can easily cause the flange to break.

Frequently Asked Questions

Most frequent questions and answers

When and where may I use a flat face flange?

Typically, less demanding applications like low-pressure water pipelines call for the usage of flat face flanges. They are frequently employed in low-temperature, low-pressure settings, including pump suctions or water treatment flanges.

What do Flat Face Flanges represent?

In the same plane as the bolting circle face, the Flat Face flange features a gasket surface. Applications that call for flat face flanges usually include casting for the mating flange or other flanged fitting. To a raised face flange, flat face flanges must never be fastened.

What differentiates a raised face flange from a flat face flange?

While raised face flanges have a raised surface, flat face (FF) flanges have a flat surface. In the same plane as the bolting circle face, these flanges feature a gasket surface. The simplest sort of flange face accessible is the flat face.

Is it possible to attach a raised face flange to a flat face flange?

It is forbidden to bolt flat face flanges to raised face flanges. According to ASME B31.1, a complete face gasket is necessary and the raised face on the carbon steel flange must be removed when attaching flat face cast iron flanges to carbon steel flanges.
