Insulation Gasket Kit
At Metrade, we supply high-performance insulation gasket kit solutions engineered to deliver reliable electrical isolation while protecting pipeline flange connections from galvanic corrosion. Designed for demanding operations in oil & gas, water transmission, petrochemical facilities, and marine environments, our kits help extend asset life and strengthen long-term pipeline integrity. They support systems exposed to harsh conditions and give operators greater confidence in the durability and safety of their networks.
Each insulation kit combines strong thermal insulation with dependable leak-proof sealing, making it ideal for applications where temperature control, energy efficiency, and overall system performance are essential. These kits work effectively across steam lines, hot water networks, and multiple thermal transfer systems, ensuring heat stays contained and energy loss stays low.

An insulation gasket kit is a specialized sealing and isolating solution used primarily in piping systems to electrically isolate flanges, prevent galvanic corrosion, and maintain the integrity of cathodic protection systems. These kits are essential in industries such as oil and gas, petrochemical, water treatment, and marine environments, where dissimilar metals or corrosive conditions are common. A typical insulation gasket kit includes an insulating gasket, insulating sleeves for the flange bolts, insulating washers, and metal backing washers. The gasket itself is usually designed in a full-face or ring type configuration and is available in different styles such as Type F (raised face), Type E (full face), or Type D (RTJ style). By preventing metal-to-metal contact, insulation gasket kits help eliminate electrical continuity across flanges, reducing the risk of electrochemical damage, leakage, and pipeline failure, thereby extending the service life of critical infrastructure.
