CS Threaded Flanges, also known as screwed flanges, are used for special applications where welding is not feasible. These flanges are designed with an internal thread that matches the external thread on the pipe, allowing for easy installation without the need for welding. Threaded flanges are ideal for small-diameter, high-pressure systems or explosive environments where welding could pose a hazard.
CS Threaded Flanges are commonly used in industries such as oil & gas, petrochemical, water treatment, power generation, and fire protection systems. They are especially suitable for non-cyclic service and low-temperature environments and are a preferred solution for pipework requiring quick assembly/disassembly or future maintenance access.
At Middle East Piping, we offer a comprehensive range of Carbon Steel Threaded Flanges manufactured as per ASME B16.5 and EN 1092-1 standards. These flanges are available in pressure ratings from Class 150 to 2500, and in sizes from ½” to 4” as threaded connections are typically limited to smaller diameters. click here
Our CS threaded flanges are manufactured from high-grade materials such as ASTM A105 (for ambient temp), A350 LF2 (for low temp), and are available with various coatings such as black paint, anti-rust oil, or hot-dip galvanized. All flanges are tested for dimensional accuracy, material properties, and pressure ratings and are supplied with EN 10204 3.1 or 3.2 mill test certificates.
Threaded flanges are an excellent choice when welding is not practical, offering secure connection and ease of replacement in compact piping networks. click here
