Basics of Inner Ring for SWG

An inner ring is a flange-mounted element that reduces the turbulence of the medium in the pipeline and helps the sealing material be more resilient. In addition to reducing turbulence, the ring also protects the sealing material, preventing it from buckling inside the pipe. It can be used in both male and female flanged connections.
Inner and outer rings are available in a variety of materials, including 304 (L) stainless steel, carbon steel, CS, metal strips; 316 (L) stainless steel. They can be punched or lathed for a diameter range of 1-2 inches to 24 inches. A wide array of materials are available, making it possible to meet the specific needs of different applications.
The inner ring is a component of a spiral-wound gasket, as are the outer and inner rings. The outer ring acts as a compression gauge and prevents over-compression of the spiral-wound. This also promotes the proper centering of the gasket within the flange. On the other hand, the inner ring acts as a retaining ring, preventing excessive compression during high-pressure service. It also increases the axial rigidity of the gasket.
Gasket seals are available with a variety of auxiliary rings, allowing users to customize their systems to fit a wide range of service conditions. These sealing systems are suited for high-pressure applications, fluctuating temperatures, and high-blow resistance. There are also gaskets designed for extremely corrosive environments. Whether you need to protect an exhaust pipe, a flanged connection, or a pump, a gasket seal will meet your needs.
