A high-performance seal manufacturer of seal products such as spring-loaded C-rings, metal seals HELICOFLEXⓇ, and metal hollow O-rings introduces important points for making metal seals functional, as well as key considerations for designers. The selection of metal seals is crucially dependent on the design of the corresponding flanges. The materials 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. ★This document can be viewed immediately by clicking the download button. 【Contents (partial)】 ■ How to make metal seals functional? ■ Seal selection based on allowable leakage rate ■ Compression and recovery of metal seals ■ Bolt load and other factors *For more details, please download the PDF or feel free to contact us.
