Spring-energized metal C-ring HELICOFLEX(R) seal

We will introduce important points for making metal seals functional, as well as key considerations for designers, from a high-performance seal manufacturer of products such as spring-loaded C-rings, metal seals like HELICOFLEXⓇ, and metal hollow O-rings. The selection of metal seals is crucially dependent on the design of the corresponding flanges. Factors such as the material of the flanges and bolts, the tightening load (minimum required bolt load during tightening), pressure, temperature, and the method of bolt fastening are all related to the occurrence of insufficient compression in metal seals. *For more detailed information, please download from the related catalog.*

The "HELICOFLEX Seal" is a spring-loaded C-ring metal seal developed in collaboration with the French Atomic Energy Commission (CEA). The remarkable performance of this product is the result of many years of research and development, experiments, and practical applications in markets such as nuclear energy, aerospace, high vacuum, oil refining/chemicals, gas, and other general industries. With flexible design capabilities, we provide customized products that meet the sealing characteristics required for your applications. 【Features】 ■ Seal diameter φ4 to 8000mm ■ Pressure range from 10^-10 mbar to 3000 bar ■ Temperature range from -272℃ to 800℃ ■ Acceptable leakage rates from liquid foam levels to ultra-high vacuum levels ■ Compatible with all flange standards and flange surfaces (PNEUROP, ASME, ISO, JIS, etc.) *For more details, please refer to the PDF document or feel free to contact us.
