Properties and Application
The metallic ring joint gaskets are manufactured according to the API 6A and ASME B16.20 standards for application at elevated temperatures and pressures. The small sealing area with high contact pressure results in great reliability. Some types of Junioseal ring-joints are pressure activated, that is, the greater the pressure the better the sealability. Our metal ring joint gaskets have been designed to withstand exceptionally high assembly loads over a small area, thus producing high seating stresses. The Junioseal ring joint gaskets are produced in several shapes and sizes, and are suitable for oil and gas pipeline flanges, pressure vessels, high speed joint faces, and other demanding applications.
