Klingersil gasket
Klingersil gasket is a type of compressed fiber gasket used as a safe and modern replacement for asbestos gaskets in industrial sealing systems. These gaskets, also known as Non-Asbestos Gaskets or Compressed Fiber Sheets, are manufactured from a combination of synthetic fibers (such as aramid), rubber binders, and mineral fillers. Due to their excellent resistance to pressure, temperature, and chemical media, they are among the most widely used sealing materials in oil, gas, steam, and petrochemical industries.
A Comprehensive Guide to Selecting and Using Klingersil Gaskets
Klingersil gaskets are composed of a dense composite structure formed through layered compression. This composition typically includes the following components:
Aramid fibers: Fibers with high thermal and mechanical resistance
Mineral fillers: Used to increase density and structural strength
Rubber binder: Such as NBR, SBR, or EPDM, providing flexibility and sealing performance
These materials are combined through a controlled hot-pressing and compression process to produce durable sheets in various thicknesses.
| Feature | Description |
|---|---|
| Thermal resistance | From −20°C up to 400°C, depending on the material grade |
| Working pressure capacity | Up to 100 bar (10 MPa) in specific models |
| Chemical resistance | Resistant to oils, steam, acids, gases, and solvents |
| High flexibility | Easy installation on uneven or imperfect sealing surfaces |
| Long service life | Suitable for continuous or semi-continuous use in industrial equipment |
