Note: Flat Face Flanges are typically used with full-face gaskets and are suitable for applications where flange faces match flat equipment surfaces.
The Flat Face Flange is a critical component in piping systems where gasket surface uniformity and reliable sealing are required. Designed with a completely flat gasket surface, the Flat Face Flange ensures full contact with the mating flange, minimizing uneven loading and reducing the risk of flange distortion during tightening. This type of flange is widely used in low-pressure and non-critical applications, such as in water treatment plants, fire protection systems, and HVAC installations.
Our Flat Face Flanges are manufactured in accordance with international standards such as ASME B16.5 and EN 1092-1. We offer Flat Face Flanges in a wide range of sizes, pressure classes, and facing types. Customers can choose from various premium materials including stainless steel and nickel alloy, which provide excellent corrosion resistance and mechanical durability. A stainless steel Flat Face Flange is ideal for water-based and sanitary applications, while a nickel alloy Flat Face Flange offers superior performance in corrosive chemical environments.
The Flat Face Flange is especially suitable for use with cast iron equipment, where minimizing stress on the mating surfaces is essential. Its flat sealing surface works well with full-face gaskets, ensuring a leak-free connection. Whether you're designing a new system or upgrading an existing one, our Flat Face Flange solutions offer reliable performance, longevity, and easy installation.
Choose our high-quality Flat Face Flange for dependable, cost-effective piping connections in low-pressure service conditions.
