Quantity
The Wuxi Dielectric Flange Gasket is a precision-engineered non-asbestos sealing solution manufactured to the ASME B16.5 standard. The gasket is die-stamped from KLINGERSIL C-4430, a premium material composed of aramid fibers reinforced with a nitrile binder. This complete isolation set includes a G10 insulating sleeve, G10 washers, and ZPS metallic back-up rings.
Technical Corrections & Material Properties
It is critical to correct the temperature limit mentioned in some literature. While the base KLINGERSIL C-4430 sheet can theoretically withstand peak temperatures up to 430 °C, the functional limit for a dielectric flange gasket with G10 sleeves is +200 °C (G10 glass-epoxy degrades above 250 °C). The operational range is -40 °C to +200 °C, with a maximum pressure rating of 100 bar. The material offers a dielectric strength of 21 kV/mm and volume resistivity >10¹² Ω·cm, effectively breaking galvanic currents between dissimilar metals. It resists oils, water, refrigerants, and weak acids, holding certifications including TA-Luft and BS 7531 Grade AX.

Performance Lifecycle (Field Data)
Our field data from power and petrochemical plants indicates the following average safe service life:
- Water/Cooling (≤80 °C): 10–12 years.
- Saturated Steam (150 °C): 5–6 years (NBR binder hardens above this threshold).
- Hydrocarbon Oils: 7–8 years.
- High-Temperature Thermal Oil (200 °C): 2–3 years.
- Strong Oxidizing Acids: Not recommended (<1 year).

Application Scenarios
This flange isolation gasket is the preferred safety solution for cathodically protected pipelines, offshore platforms, and power plant cooling water systems. It solves the"triangle of death"in flange joints: media corrosion, galvanic corrosion, and seal failure. By utilizing a 3XA anti-stick coating, it provides excellent creep resistance and recovery, lasting three times longer than traditional asbestos gaskets.
