The Type D Insulating Gasket Kit is a premium solution designed to ensure both effective sealing and electrical isolation in high-pressure piping systems. Specifically engineered for 10-inch, 600LB flanges with a ring-type joint (RTJ) face, this gasket kit is ideal for critical service applications such as oil and gas, petrochemical, refinery, marine, and offshore installations. The gasket itself is manufactured in an oval shape to conform precisely to the RTJ flange groove, ensuring a tight, reliable seal that withstands both pressure and environmental challenges.
At the heart of the kit is a phenolic retainer, a non-conductive and corrosion-resistant material known for its excellent mechanical strength, low water absorption, and superior dielectric properties. This retainer provides the backbone of the insulating and sealing ring, enabling the gasket to perform effectively under a wide range of temperatures and pressures while preventing metal-to-metal contact between the flanges. By eliminating the electrical path, the gasket mitigates galvanic corrosion and prevents stray currents from compromising pipeline integrity.
The Type D Insulating Gasket Kit includes all the necessary components for complete flange insulation. It comes fully assembled with an isolating and sealing ring, full-length bolt isolating sleeves, and two 1/8-inch thick steel washers for each bolt. The bolt sleeves insulate the bolts from the flange holes, while the steel washers provide mechanical support and maintain proper torque, contributing to a consistent and secure installation. This full-component design ensures comprehensive electrical isolation across the entire flange assembly.
Whether used in above-ground piping systems or submerged environments, this gasket kit delivers exceptional performance and longevity. It is particularly effective in preventing leakage and electrical continuity in cathodic protection systems or areas where dissimilar metals are used. With its reliable construction and complete configuration, the Type D Insulating Gasket Kit is an essential solution for enhancing safety, reducing maintenance costs, and prolonging the service life of pipeline systems.Know more about China Manufacturer
