insulating gasket kit

add to cart Insulating Gasket Kit ustries, this product benefits from decades of local expertise in precision molding and high-pressure sealing technologies. The industrial cluster has steadily evolved into a key supplier hub for oil, gas, and chemical infrastructure, ensuring strict quality control and cost-effective production. Technical Specifications and Core Components The kit is dimensioned for 8-inch piping, rated to Class 300LB (ASME B16.5), and features a Type F (Flat-Face) design, which ensures uniform gasket compression across the flange surface—critical for leak-tight performance in demanding environments. The total gasket thickness is 3.2 mm, complying with standard dimensional requirements for raised-face and flat-face flanges. The component set includes: - G11 Insulating Sleeves: Manufactured from high-grade glass-reinforced epoxy laminate, offering dielectric strength >15 kV/mm and excellent creep resistance, even at elevated temperatures. - Insulating Washers: Paired with the sleeves to break the electrical path between flange bolts and the pipe wall, preventing stray current interference. - ZPS (Zinc-Plated Steel Washers): Provide mechanical load distribution and enhanced corrosion resistance in outdoor or humid environments, extending bolt life and maintaining torque retention. Performance and Application Scenarios The Insulating Gasket Kit effectively isolates electrical currents, preventing galvanic cell formation between dissimilar metals—a common failure mode in offshore platforms, compressor stations, and refinery transfer lines. Its chemical resistance covers a wide pH range (2–12) and operational temperatures from -40°C to +200°C, making it suitable for hydrocarbon, sour gas (NACE-compliant), and cooling water systems. The F-type flat-face geometry simplifies installation, reduces gasket misalignment risks, and ensures reproducible sealing stress, which is validated by hydrostatic and pneumatic tests per ASTM F104. Customization and Quality Assurance While the standard 8-inch 300LB kit addresses most industrial needs, we offer tailored dimensions for non-standard flange drilling patterns or larger diameters. Each batch undergoes dielectric strength verification, compression set testing, and dimensional inspection in our facility, which holds ISO 9001 and API 6A-equivalent certifications. The synergy of G11, insulating washers, and ZPS components guarantees a service life exceeding 10 years in typical cathodic protection duty cycles. Conclusion For engineers seeking a reliable, cost-efficient insulation solution, the Insulating Gasket Kit delivers uncompromising sealing integrity and electrical isolation. Backed by ’s robust manufacturing ecosystem and our commitment to technical support, this kit is a trusted choice for safeguarding pipelines against corrosion. Whether for standard retrofits or custom-engineered projects, we provide full documentation, including dimensional certificates and material test reports, to ensure seamless integration into your CP strategy. Choose the kit—where regional craftsmanship meets global performance standards.
