An exhaust flange is a device used to attach an exhaust pipe to an exhaust manifold or another piece of exhaust pipe. Commonly designed to sandwich an exhaust gasket between the exhaust manifold and the exhaust pipe, the exhaust flange is manufactured to an exact angle to eliminate the chance of any exhaust leaks when tightened.
What is a Pipe Flange? A pipe flange connects piping and components in a piping system by use of bolted connections and gaskets. Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance. Most common specification for carbon steel and stainless steel flange is ANSI B16.5 / ASME B16.5. Metal flanges are commonly used for industrial, commercial, and institutional application. Steel pipe flanges are available in variety of styles and pressure classes. Metal flanges are classified from 150 to 2500 # rating.
