Spring - energized metal C - ring seal is a high - performance, flexible metal sealing component which features outstanding compression and elastic recovery capabilities. This seal consists of a tightly wound helical spring encircled by one or multiple metal sheaths. The spring is engineered to possess a specific resistance to compression. When undergoing compression, the specific pressure generated compels the sheath to deform and fill the flaws on the flange, all the while guaranteeing firm contact with the flange sealing surfaces. Every coil of the helical spring functions independently, enabling the seal to adapt to the surface irregularities of the flange.
Types
Metal C-Ring for Internal Pressure (MCI): a resilient internally pressurized static face seal open on the inside, enabling it to bear the same pressure as its internal operational conditions. Ideal for assemblies, pressure vessels, jet engines, fuel injectors, lighter flanges, etc.
Metal C-Ring for Axial Pressure (MCA): a sturdy dynamic axial seal designed to endure the same pressure as its axial operational conditions. It’s an optimal choice for static and low-cycle dynamic axial sealing applications. It is suitable for use in various industrial settings, including hydraulic systems and high-temperature shaft sealing.
Metal C-Ring, spring energized for External Pressure (MCE-F): shaped like MCO, but this ring can withstand higher loads, making it ideal for use with rougher mating surfaces. It’s primarily designed for externally pressurized joints and flanges with a rougher surface finish. Additionally, it can be used for internally pressurized joints to prevent the working fluid from entering the seal cavity, although this comes with a reduced working pressure rating.spring energized metal c-ring for axial pressure
Metal C-Ring,spring energized for Axial Seals (MCA-F): the axial seal is specifically designed to seal against an I.D. and O.D. of the cavity.Axial Seals are ideally suited to accommodate limited rotational or linear movements such as those found in liquid or gas valves. Since Axial Seals are metallic, they are ideal for use in cryogenics, superheated steam or high pressure viscous liquids.
