What is the suitable gasket material for a flange union used in oil lines?

When selecting a gasket material for a flange union used in oil lines, it is essential to consider the operating conditions such as temperature, pressure, and the type of fluid being transported. Metallic gaskets are often regarded as the suitable choice in this context due to their durability and resistance to high temperatures and pressures, which are common in oil lines. They can also handle the chemical properties of various oils without degrading over time.

Metallic gaskets provide a reliable seal because they can compress well and maintain their integrity under mechanical stress. This is particularly important in oil lines where leakage could lead to significant safety and environmental hazards. The ability of metallic materials to resist wear and tear, alongside their strength, contributes to their effectiveness in these applications.

Other materials, such as rubber or plastic, may not provide the same level of resilience or compatibility with the operational demands of oil lines. Non-metallic gaskets might also lack the necessary sealing power under extreme conditions, making them less suitable for this specific application. This highlights the importance of choosing the right material for the job to ensure the integrity and safety of the system.
