The Type 604HTC high-temperature, corrosion-resistant welded metal bellows seal is a unique advanced technology for reliably sealing fluids in harsh, high-temperature, corrosive environments and, at the same time, provides superior face stability at elevated temperatures. This all-Inconel seal is ideally suited for applications that contain organic acids (naphthenic acid), and sulfur compounds that attack most other alloys at high temperature. The Type 604HTC is a stationary bellows assembly that is capable of handling high shaft speed applications and high shaft-to-seal chamber misalignment. The 604HTC is utilized in our API 682/ISO 21049 Type 1604HTC and Type 3604HTC cartridge seals.
