Metal 84 inner arc ring packing, stainless steel bulk packing, chemical packing
Metal fillers have good surface wetting properties and should be prioritized for use in non corrosive or low corrosive systems. However, if carbon steel is used in corrosive environments, it may rust; Stainless steel packing has strong corrosion resistance and can generally withstand corrosion from rare substances other than Cl -, but it has a high cost and good performance; Fillers made of materials such as titanium and special alloy steel have a high cost and are generally only used in certain highly corrosive systems.
