Type E Dielectric Flange Bolt Kit

The Type E Dielectric Flange Bolt Kit is a product specifically designed to meet high insulation demands. Constructed from Klingersil C4400 material, which incorporates aramid fiber reinforcement and nitrile adhesive, it assures remarkable mechanical strength and robust chemical corrosion resistance. Compliant with the ASTM D149-95a standard, its dielectric strength meets stringent electrical isolation requirements. The kit is suitable for 6-inch flanges with a pressure rating of 150LB and includes G10 insulating sleeves, gaskets, and ZPS insulating washers, forming a complete insulation assembly. It is ideal for industries such as chemical, petroleum, and natural gas, effectively preventing galvanic corrosion and current leakage, thereby enhancing system safety and reliability.  

Mechanical Strength  

The mechanical strength of Klingersil C4400 constitutes one of the core advantages of the Type E Dielectric Flange Bolt Kit. Thanks to its unique material structure and high-performance components, it maintains exceptional stability under high pressure, high temperature, and complex working conditions.  

1. Tensile Strength

Klingersil C4400 is composed of aramid fiber reinforcement and nitrile adhesive. The high-strength properties of aramid fiber substantially augment the overall tensile performance of the material.  

Tensile Strength: ≥50 MPa (ASTM D638)  

Elongation at Break: ≤5%  

These properties indicate that the material can maintain highly high strength under tensile force while exhibiting minimal deformation, making it ideal for applications requiring long-term stable sealing. The Type E Dielectric Flange Bolt Kit leverages these characteristics to ensure stable performance even under high-pressure conditions.  

2. Compressive Strength  

Under high-pressure environments, Klingersil C4400 exhibits excellent compressive strength, effectively resisting compressive forces in flange connections and preventing excessive deformation or material failure.  

Compressive Strength: ≥100 MPa (ASTM D695)  

Compression Rate: 10-15% (ASTM F36)  

This combination of low compression rate and high compressive strength ensures that the material maintains good sealing performance under high-pressure conditions. The Type E Dielectric Flange Bolt Kit is specifically designed for such high-pressure environments.  

3. Resilience  

Klingersil C4400 exhibits commendable resilience, allowing it to quickly return to its original shape after the load is released, ensuring tight contact on the sealing surface.  

Resilience Rate: ≥30% (ASTM F36)  

This characteristic makes it appropriate for applications with frequent opening and closing or dynamic loads, such as valve and pump connections. The resilience of the Type E Dielectric Flange Bolt Kit makes it perform exceptionally well in these applications.  

4. Anti-Creep Properties  

Under long-term load, Klingersil C4400 demonstrates extremely low creep characteristics, effectively preventing sealing failure caused by material deformation.  

Creep Rate: ≤1% (1000 hours, room temperature)  

This property makes it particularly suitable for industrial equipment that requires long-term, stable operation, such as chemical pipelines and high-pressure vessels. The anti-creep performance of the Type E Dielectric Flange Bolt Kit guarantees its long-term reliability in these applications.  

5. Shear Strength  

In flange connections, shear force is a prevalent form of stress. The high shear strength of Klingersil C4400 ensures its integrity under complex stress conditions.  

Shear Strength: ≥30 MPa (ASTM D732)  

The Type E Dielectric Flange Bolt Kit is designed to withstand such complex stresses, ensuring stable performance even under high shear forces.  

6. Fatigue Strength  

Klingersil C4400 exhibits excellent fatigue strength under cyclic loads, capable of enduring multiple stress cycles without failure.  

Fatigue Limit: ≥20 MPa (10⁶ cycles)  

 This strength enables it to endure numerous stress changes without experiencing fatigue failure. In dynamic load settings, such as in valves and pumps with frequent on-off operations in industrial pipelines, the kit performs well. Its fatigue strength ensures reliable long-term use and reduces the risk of early component breakage from cyclic loading.

The mechanical strength data of Klingersil C4400 fully demonstrate its excellent performance under high pressure, high temperature, and complex working conditions. Whether in terms of tensile, compressive, resilience, or anti-creep properties, it meets the high standards required for industrial applications. The Type E Dielectric Flange Bolt Kit, designed with these characteristics in mind, is an ideal choice for flange sealing, insulation protection, and anti-corrosion applications.
