A flat sealing component, extending to the outer edge of a pipe flange, is employed to create a leak-proof seal between two mating flanged connections. These components typically feature bolt holes that align with the flange bolt pattern, ensuring uniform compression when tightened. They are commonly manufactured from materials like rubber, compressed fiber, or PTFE, depending on the application’s temperature, pressure, and chemical compatibility requirements. As an example, a system transporting water at ambient temperature and low pressure may utilize a neoprene variation, whereas a high-temperature, corrosive chemical process might necessitate a PTFE-based alternative.
This type of sealing solution offers several advantages, including ease of installation and broad compatibility with various flange types. Its design distributes compressive force evenly across the entire flange face, enhancing the seal’s effectiveness, particularly in low-pressure applications or with flanges prone to distortion. Historically, these seals provided a simple, reliable method for joining pipe sections in early industrial piping systems. Their ongoing relevance stems from their ability to compensate for minor flange surface imperfections and provide a secure, readily replaceable seal.
