Engineered Gaskets for Reliable Sealing

At METRADE, our Type D (RTJ) flange insulation kits are engineered to meet rigorous industry standards, ensuring superior sealing performance, enhanced corrosion protection, and long-term operational reliability. A Type D (RTJ Type) gasket used in a flange insulation kit is specially designed for Ring Type Joint (RTJ) flanges, where the gasket fits precisely into the machined groove of the flange. This design ensures a highly reliable seal under high-pressure and high-temperature conditions, while also providing effective electrical isolation between flange faces.

As part of a complete flange insulation kit, the Type D gasket is used along with insulating sleeves, insulating washers, and metal backup washers to prevent galvanic corrosion and eliminate stray current flow in critical pipeline systems. These kits are widely used in industries such as oil & gas, petrochemical, and power generation, where RTJ flanges are common and system integrity is essential.
