Here are some important points to consider when selecting metal seals such as spring-energized C-rings! <Materials available upon request>
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-energized 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.
