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

What is a flat face flange?

A flat face flange is a type of flange that has a flat surface on both sides. It is used to connect pipes, valves, and other equipment in a piping system.

What are the advantages of using flat face flanges?

Flat face flanges are easy to clean and maintain, and they provide a tight seal when properly installed. They also have a lower profile than raised face flanges, which can be beneficial in certain applications.

What are the dimensions of a flat face flange?

The dimensions of a flat face flange can vary depending on the size and type of flange. Common dimensions include the diameter of the bolt circle, the number of bolt holes, and the size of the flange face.

What is the pressure rating of a flat face flange?

The pressure rating of a flat face flange can vary depending on the material and size of the flange. Common pressure ratings for flat face flanges include 150, 300, 600, 900, and 1500 pounds per square inch (psi).

What materials are flat face flanges made of?

Flat face flanges are made from a variety of materials, including carbon steel, stainless steel, and alloy steels. They can also be made from plastic or other non-metallic materials.

How are flat face flanges installed?

Flat face flanges are typically installed using bolts and nuts. The flange is aligned with the pipe or other equipment, and the bolts are tightened to create a tight seal. Gasket is used between flange faces to make sure there is a perfect seal.

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.

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.

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

A raised face flange has a raised surface or lip on one side of the flange, while a flat face flange has a flat surface on both sides. The raised surface on a raised face flange is used to provide a better seal and to help contain pressure within the piping system. The raised surface also helps to prevent leakage and to reduce the risk of erosion or turbulence. On the other hand, flat face flanges are used in applications where a smooth, uninterrupted surface is required, such as in certain types of valves or other equipment. Additionally, flat face flanges have a lower profile, which can be beneficial in certain situations.

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.
