Wuxi Insulating Kit for Flange

The insulating Kit for Flange is designed explicitly for B16.5 flanges and is suitable for Class 300 pressure ratings and DN300 pipeline systems. The kit utilizes high-performance, non-metallic materials, with both the Carrier Disc and Insulating Sleeves made from G10 epoxy fiberglass. This material offers outstanding mechanical strength and insulation properties, guaranteeing stable operation under high-pressure conditions. The Sealing Element is crafted from Viton fluorocarbon rubber, which is resistant to high temperatures and corrosion, making it suitable for a variety of demanding applications. The gasket section combines G10 with ZPS (Zero Penetration Sealing Technology), effectively preventing media penetration and extending service life. The Insulating Kit for Flanges is an ideal choice for industries such as the chemical, oil, and gas sectors, providing safe and reliable insulation and sealing components.  

High Mechanical Strength  

The Carrier Disc and Insulating Sleeves in the Insulating Kit for Flange are manufactured from G10 epoxy fiberglass. G10 material boasts a tensile strength of up to 300 MPa and a compressive strength of 500 MPa, significantly surpassing the tensile strength of common engineering plastics, such as nylon, which has a tensile strength of approximately 80 MPa. This high mechanical strength ensures the stability of the **Insulating Kit for Flange** under high pressure (e.g., Class 300, approximately 5.1 MPa) and vibrating environments, effectively withstanding mechanical stress and impact in pipeline systems, preventing deformation or damage. In contrast, traditional PTFE (polytetrafluoroethylene) material, while excellent in corrosion resistance, has lower mechanical strength (tensile strength of approximately 20-30 MPa) and is prone to creep or failure under high-pressure conditions.  

Dimensional Stability

G10 material's low water absorption (less than 0.1%) and low thermal expansion coefficient (12 × 10⁻⁶/°C) provide exceptional dimensional stability in humid and temperature-varying environments. For example, in environments with humidity levels of up to 95%, the dimensional changes of G10 material are almost negligible. In contrast, common nylon materials can exhibit water absorption rates of 2.5% to 3%, resulting in significant expansion. Additionally, G10's thermal expansion coefficient is significantly lower than that of metallic materials (e.g., carbon steel has a thermal expansion coefficient of 11.7 × 10⁻⁶/°C). This allows G10 to maintain a stable geometry across a wide temperature range, from - 50°C to 150°C, thereby avoiding sealing failures resulting from thermal expansion and contraction.  The Insulating Kit for Flange leverages the superior properties of G10 material to demonstrate exceptional reliability in high-pressure, high-humidity, and temperature-changing environments. In comparison, PTFE has a thermal expansion coefficient as high as 100 × 10⁻⁶/°C, making it prone to dimensional changes under temperature variations, which can compromise its sealing performance.  

In summary, the high mechanical strength and excellent dimensional stability of G10 material render it an ideal choice for the Insulating Kit for Flange in high-pressure, high-humidity, and temperature-varying environments. Compared to common engineering plastics such as nylon and PTFE, G10 offers significant advantages in terms of performance and reliability, ensuring long-term stable operation for flange insulation kits.
