What is a flat flange?

Jul. 04, 2025

A flat face flange, also known as a raised face flange, is a flange that has a smooth flat surface on the mating side (where the gasket or sealing surface is located). This flat surface provides a flat surface against which the gasket can be compressed to form a seal between the two flanges. Flat face flanges are often used in piping systems and pressure vessels where a safe and reliable seal is required.

Flat face flanges are one of the most common flange types used in the industrial sector. It is designed to provide a simple and effective way to connect two pipes or components together. There is a ridge in the center of the flange that helps to properly position the gasket and ensure that the mating flanges are properly aligned.

When installing a flat face flange, a gasket is placed between the two mating surfaces to form a seal. This gasket can be made of a variety of materials, such as rubber, fiber, or metal, depending on the application and the media being contained. The flat surface of the flange allows for a tight seal, which is critical to maintaining the integrity of the system in which it is used.

Flat face flanges are available in a variety of sizes and pressures and can be made from a variety of materials, including carbon steel, stainless steel, and other alloys. They are suitable for a variety of applications, including water, oil, gas, and chemical services.
