Strategies for Sealing Challenging Chemical Flanges Effectively
Effective sealing in chemical processes with challenging flange configurations requires careful material selection and precise installation techniques. Restructured PTFE infused with hollow glass microspheres offers a promising solution due to its superior chemical resistance and high compressibility. Unlike traditional PTFE, this engineered material minimizes creep and conforms better to flange surfaces, even under low bolt loads, making it suitable for demanding chemical sealing scenarios. To achieve optimal results, follow these key steps: 1. **Evaluate Operating Conditions:** Understand the chemical media involved, temperature and pressure ranges, flange materials, and surface conditions. This comprehensive assessment helps determine the specific sealing requirements. 2. **Understand Material Advantages:** Recognize how restructured PTFE with glass microspheres provides enhanced compressibility, chemical resistance, and mechanical flexibility, especially beneficial for irregular flange surfaces or delicate materials. 3. **Choose the Right Gasket:** For applications involving fragile or glass-lined flanges, select gaskets like TEADIT Tealon® TF1570, which are designed to per...
