Engineered for ReliabilityKing Seal 7700 is designed for high-responsibility environments where sealing integrity is critical, such as in chemical processing and refineries. Its combination of expanded graphite and stainless steel reinforcement provides excellent resistance to thermal cycling, chemicals, and extreme pressures. The gasket assures effective performance across a wide temperature spectrum, from -200C to 550C.
Versatile Applications Across IndustriesSuitable for use in pumps, valves, and flange connections, King Seal 7700 adapts easily to customer-specific size and shape requirements. Its compatibility with steam, gas, oil, and chemical mediums makes it a preferred choice among manufacturers, suppliers, and exporters in India seeking reliable and adaptable gasket solutions.
Long Shelf Life and Maintenance BenefitsWith a shelf life of 5 years, King Seal 7700 gaskets require minimal maintenance once installed. Their robust surface finish and hardness profile ensure durability and reliable performance, minimizing costly downtime and leakage-related issues in industrial equipment.
FAQ's of King Seal 7700:
Q: How is King Seal 7700 installed in pumps, valves, and flanges?
A: King Seal 7700 is typically installed by positioning the gasket or ring between the mating surfaces of pumps, valves, or flanges, ensuring alignment with bolt holes. Tighten the assembly according to manufacturer-specified torque to achieve an optimal seal.
Q: What materials are used in the construction of King Seal 7700 gaskets?
A: King Seal 7700 gaskets are made from expanded graphite with a stainless steel 304 inner ring and a stainless steel 316 outer ring, enhancing chemical resistance and mechanical strength.
Q: When should King Seal 7700 gaskets be replaced?
A: It is recommended to replace the gasket after significant equipment maintenance, when signs of wear or leakage are noted, or before the five-year shelf life ends, to ensure uncompromised sealing performance.
Q: Where is King Seal 7700 most commonly used?
A: This gasket is widely used in industries requiring high-performance sealing, such as petrochemicals, power generation, and manufacturing plants where pumps, valves, and flanges are present.
Q: What benefits does King Seal 7700 offer over traditional gasketing materials?
A: King Seal 7700 offers superior temperature and pressure resistance, minimal leakage, excellent recovery and compressibility, and chemical compatibility, resulting in extended service life and reduced maintenance costs.
Q: How does the expanded graphite with stainless steel insert improve performance?
A: The expanded graphite provides flexibility and thermal stability while the stainless steel insert reinforces the gasket, enabling it to withstand high pressures and aggressive chemicals without deformation or failure.
