Type 1604HTC

Garniture cartouche simple stationnaire API 682 à soufflet métallique soudé de type C, Arrangement 1

The Type 1604HTC is an API 682 qualified single stationary bellows cartridge seal Type C, Arrangement 1. The Type 1604HTC incorporates all-Inconel HTC technology to reliably seal high-temperature corrosive fluids. The seal includes a segmented spring-loaded carbon throttle bushing for effective containment with a retained mating ring for vacuum service. The cartridge seal also incorporates a steam guide for effective use of a quench (steam) that helps eliminate coking problems often associated with hot hydrocarbon applications. The Type 1604HTC is able to handle higher-speed applications.
