What shape are ring joint gaskets typically in cross-section?

Ring joint gaskets are typically in an oval shape when viewed in cross-section. This design is specifically engineered to provide a reliable seal in high-pressure applications, making them a preferred choice in areas such as the oil and gas industry. The oval cross-section allows for a more effective distribution of pressure across the sealing surfaces, ensuring that the gasket conforms effectively to the flange, enhancing the integrity of the seal and minimizing the risk of leaks. This unique shape accommodates the movement and thermal expansion that can occur within the system, maintaining a tight seal under various operating conditions.
