Type 1604HTC - Single stationary bellows cartridge seal Type C, Arrangement 1 • Type 2609HTC - Dual unpressurized rotating bellows cartridge seal Type C, Arrangement 2 • Type 3609HTC - Dual pressurized rotating bellows cartridge seal Type C, Arrangement 3 These dependable API 682 cartridge seals utilize two impressive design innovations by incorporating high-temperature corrosion resistant sealing (HTC) and unique high-temperature live-loaded (HTL) mating ring technology in dual seal arrangements. This new design vastly enhances seal face stability over conventional designs and can extend mean time between repair (MTBR) in many services. Exceptional Face Stability The HTC primary seals, patent pending, incorporate specially designed pressure compensating seal faces and thermally compliant components that provide superior seal face stability at elevated temperatures. With advanced HTL mating ring design, patent pending, seal face stability is achieved by eliminating any thermal and mechanical forces that can contribute to seal face distortion. The sealing interface remains exceptionally stable in spite of thermal changes and adapts to the wide range of temperature excursions inherent in high-temperature applications. Corrosion Resistance These all-Inconel® seals are ideally suited for applications that contain organic acids (naphthenic acids) and sulfur compounds that attack most other alloys at h

Technical Specification Typical Type 1604HTC API Type C Arrangement 1 - Single Cartridge Retained Mating Ring for Vacuum Service A single stationary Type 1604HTC seal that contains a steam guide (steam deflector or anti-coking baffle) which directs steam to the area where coke would tend to form and routes the steam to carry material away from the seal and seal faces. Typical Type 2609HTC/3609HTC API Type C Arrangements 2 and 3 - Dual Cartridge Dual Scroll Pumping Device A dual seal with a Type 609HTC inner seal and Type 609 outer seal. Typically used with API Plan 52 or 53A/B/C.

^BELLOWSSEALS 1604HTC/2609HTC/3609HTC Technical Specification HTL Mating Ring (High-Temperature Live-Loaded) COMPONENTS HTL technology utilizes a specially shaped mating ring, compression ring, and energized Z-Spring to “live-load” the secondary flexible graphite packing and to control any radial and axial forces that may be imparted to the mating ring. By utilizing components with similar coefficients of thermal expansion and by eliminating contact with metal surfaces, the HTL mating ring design minimizes and/or eliminates face distortion due to the relative differences in the thermal...

^BELLOWS SEALS 1604HTC/2609HTC/3609HTC Technical Specification Sealide-C Advanced Silicon Carbide Composite Primary Ring Sealide-C is a state-of-the-art, sintered silicon carbide with low friction and the inherent lubricity of free graphite. This silicon carbide is a tough, hard, heat resistant, long wearing, inert seal face material. When compared with other face materials, Sealide-C provides improved corrosion resistance, improved thermal shock resistance, and lower running face temperatures. Design Features: • Optimum 45° tilt angle • Three-sweep radius • nesting ripple plate design •...
