  1. Solving the Two Most Common Problems with High Temperature Gaskets

    Leave a Comment

    Gaskets play a crucial role in maintaining a secure seal between connected parts or surfaces, preventing fluid leaks and energy transfer. However, when it comes to high temperature applications, gaskets face two primary challenges: compression set due to prolonged exposure to high temperatures and extrusion or blow out caused by high pressure. Below, we will explore these two common problems and introduce innovative solutions provided by RCF Technologies to overcome these challenges.

    Problem 1 – Compression Set

    Exposure to high temperature over an extended period can cause gaskets to experience compression set, where the material loses its ability to bounce back to its original shape, leading to leakage. Different gasket materials have varying temperature limits. While metallic and composite seals can withstand temperatures above 1000°F (537°C), elastomeric or rubber gaskets have a lower operating temperature of around 350°F (177°C). However, there is a solution that surpasses these limitations.

     

    Rishon® Material for High Temperature Stability

    RCF Technologies offers a revolutionary material called Rishon®, which is a combination of RCF’s proprietary silicone and fiberglass. This unique composite allows Rishon® to withstand temperatures from -170°F to +850°F (-112.2°C to +454.4°C) continuously. Not only does Rishon® excel in high-temperature applications, but it is also an FAA-approved fire barrier in thicknesses as low as .027″. By incorporating Rishon® gaskets, you can avoid compression set and ensure a reliable seal even in extreme temperature environments.

     

    Problem 2 – Extrusion or Blow Out

    Extrusion or blow out from high pressure presents another challenge for gaskets. This occurs when the pressure forces the gasket material to deform or dislodge, resulting in leaks and potential system failure. Overcoming this problem requires an innovative approach.

     

    Solution: Rishon® Shim Gaskets for High-Pressure Applications

    RCF Technologies has developed a solution to combat extrusion and blow out using Rishon® material together with unique design innovations. By utilizing a 1–10 mm shim faced with a single ply of Rishon® on either side, the gasket gains the strength of a metal gasket while retaining the excellent sealing properties of rubber. This unique design ensures that no extrusion or blow out occurs, even in applications with narrow gaps, high pressures, or multiple bolt holes. With Rishon® shim gaskets, you can achieve a secure and reliable seal under extreme pressure conditions.
