About Mechanical seal type 604htc
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.

Product Description type 604htc
The Type HTC* high-temperature corrosion resistant welded metal bellows seal is a unique advanced technology for reliably sealing fluids in harsh high-temperature corrosive environments. The Type HTC also provides superior face stability at elevated temperatures.
This all-Inconel ® seal eliminates the need for plating and is ideally suited for applications that contain organic acids, broadly referred to as naphthenic acid, and sulfur compounds that attack most other alloys at high-temperature.
Specially designed pressure-compensating seal faces and a thermally compliant primary ring adapter provide exceptional seal face stability that adapts to a wide range of temperature excursions inherent in high-temperature applications.
Even if the application is not corrosive, the extra face stability provided by the seal can extend your MTBR in many other noncorrosive services.
The API 682/ ISO 21049 qualified HTC seals are available in both stationary and rotating configurations, and single and dual seal arrangements.
