Ensuring reliable flange connections: common flange face types explained
Flange connections play a vital role in various industrial piping systems, providing secure and leak-free connections between pipes, valves, and equipment. One essential aspect of flange connections is the choice of the sealing face type, which directly impacts the overall performance and reliability of the connection. In this article, we will explore the common flange face types and their applications, helping you make informed decisions for your specific piping needs.
EN 1092 Q235 FF flat flanges
Flat Face: The Flat Face sealing surface is the simplest and most straightforward type, where the flange faces are flat. Typically used in low-pressure and non-metallic flange applications, Flat Face connections provide satisfactory sealing performance under moderate temperature and pressure conditions.
Weld Neck Flange Raised Face P250GH
Raised Face (RF): Raised Face flanges feature a raised circular area on the flange face. When two flanges are connected, the raised area compresses the flange gasket, forming a reliable seal. RF flanges are commonly used in general industrial piping systems and provide effective sealing in a wide range of applications.
Tongue and Groove Flange
Tongue and Groove: Tongue and Groove flange faces consist of a tongue on one flange face and a corresponding groove on the other. This configuration creates a sturdy and leak-proof connection, making it suitable for high-pressure and high-temperature applications that demand a robust seal.
Male and Female: Male and Female flange faces involve a specially designed surface on each flange, with a male part fitting into a corresponding female part. This type of flange face offers excellent sealing capabilities, particularly in high-pressure and high-temperature piping systems, ensuring secure and reliable connections.
SS316 RTJ Blind Flanges
Ring Type Joint (RTJ): RTJ flange faces feature a groove with a metal ring gasket that sits in the groove. When the flanges are bolted together, the metal ring gasket deforms to create a tight seal. RTJ flanges are extensively used in critical applications with extreme pressures and temperatures, offering superior sealing performance.
Oval: Oval flange faces consist of an elliptical-shaped sealing area on the flange face. This specialized sealing face is employed in specific applications, such as high-temperature and high-pressure connections, where traditional sealing faces may not suffice.
Selecting the appropriate flange face type is crucial in ensuring the reliability and safety of piping connections in industrial applications. The choice depends on various factors, including operating conditions, pressure, temperature, and the medium being transported. At Haihao Group, we offer a wide range of high-quality flanges and expertise to help you make informed decisions and achieve secure and efficient flange connections for your projects. Choose the right flange face type with confidence, knowing it will meet your specific needs and industry standards.
