Quantity
Jiangsu presents its premium Flange Insulation Gasket Kit, engineered specifically for Ring Type Joint (RTJ) flanges in demanding pipeline systems. This complete insulation kit delivers critical electrical isolation and cathodic protection, preventing galvanic corrosion between dissimilar metals while maintaining a leak-tight seal under extreme conditions. Rated for 900LB pressure class, this kit ensures operational safety and extends service life in oil & gas, petrochemical, and offshore platforms.
Key Features & Benefits
- Reliable Electrical Insulation: The combination of G10 retainers, PTFE sleeves, and Viton seals provides robust dielectric isolation, effectively breaking stray currents and protecting flange faces from electrochemical attack.
- High-Pressure Performance: Designed for 900LB service, this kit withstands elevated pressures and thermal cycling without compromising seal integrity.
- Chemical & Temperature Resistance: Viton and PTFE components resist aggressive media, including sour gas, brine, and aromatic hydrocarbons, across temperatures from -20°C to +200°C.
- Precision Fit: Type F design ensures exact mating with RTJ flanges, reducing installation errors and gasket extrusion.
