Insulation Flange Gasket Kit

The 2-inch Insulation Flange Gasket Kit, rated for 150 IB, is designed explicitly for electrochemical corrosion protection and electrical insulation. It incorporates high-performance PTFE quadruple sealing technology to ensure exceptional sealing and durability. The main body of the gasket is made of G10 material, which provides excellent insulation properties and mechanical strength. Additionally, the kit includes G10 sleeves and galvanized washers, which further enhance insulation effectiveness and provide extra corrosion protection. This Insulation Flange Gasket Kit is ideal for demanding industrial environments requiring electrical isolation and corrosion resistance, making it an indispensable and reliable solution for pipeline systems.  

Outstanding Insulation Performance

G10 material, as a high-performance insulating material, excels in its extremely low conductivity and superior dielectric strength.  

1. Extremely Low Conductivity  

The volume resistivity of G10 material typically ranges between 10^12 - 10^14 Ω·cm, meaning it is nearly non-conductive and effectively isolates electrical currents, preventing conduction through the Insulation Flange Gasket Kit. This feature is outstanding for electrical insulation applications, especially where protection against electrochemical corrosion and stray current interference is needed.

2. High Dielectric Strength  

The G10 material used in the Insulating Kit for Flange exhibits a dielectric strength exceeding 20 kV/mm. This extraordinary property empowers it to endure exceedingly high voltages without succumbing to electrical breakdown. 

3. High Surface Resistivity  

The surface resistivity of G10 material typically ranges between 10^11 - 10^13 Ω. Such a high surface resistivity serves as an effective deterrent to the flow of surface leakage currents. Impeding these unwanted currents guarantees the long-term stability of the insulation performance of the Insulating Kit for Flange.

 4. Prevention of Electrochemical Corrosion  

Within pipeline flanges and metal equipment, the interaction between dissimilar metals often triggers electrochemical corrosion. The Insulation Flange Gasket Kit prevents such corrosion by isolating metal contact and blocking current pathways. For instance, in marine environments, G10 gaskets significantly extend the service life of metal equipment and reduce maintenance costs.  

5. Suppression of Stray Current Interference

In scenarios such as electrified railways and high-voltage transmission lines, stray currents can cause corrosion to pipelines and equipment. The Insulation Flange Gasket Kit has high resistivity and low conductivity, effectively blocking the conduction of stray currents and protecting equipment from damage.

In oil and gas pipelines, the Insulation Flange Gasket Kits are extensively utilized at flange connections to prevent stray currents and electrochemical corrosion. For example, in a subsea pipeline project, the corrosion rate was reduced by over 90% after implementing the Insulation Flange Gasket Kit, significantly extending the pipeline's service life.
