Spiral wound gaskets – versatile application and highclass workmanship
In order to be able to meet the individual requirements of our customers, we offer various types of spiral wound gaskets: For example, you can choose between standard versions with a smooth surface and various special models. All articles are based on a stainless steel strip and high-quality filling materials such as graphite and PTFE, which underlines the excellent quality standard. The spiral wound gaskets of billi are characterized by a constant elasticity during hot-cold cycles. Classical applications in the chemical industry include all types of gas lines, directional valves and pumps. Furthermore, spiral wound gaskets are the optimal solutions for pressure vessel openings in steam systems as well as low and high pressure in nuclear power plants.
Spiral wound gaskets in various designs can be ordered conveniently from us
For the best possible functionality of spiral wound gaskets, the careful considered choice of model is of central importance: the versions with centering ring, for example, assures an ideal fit between the bolts. In addition, the centering ring prevents the radial flow of soft filling materials such as PTFE. The inner rings, on the other hand, minimize the flow resistance, effectively containing crevice corrosion. In addition, such an inner ring acts as a compression limiter and optimizes the effect of the sealing elements.

Features and advantages of spiral wound gaskets
Both high temperature and pressure resistance count as main advantages of spiral wound gaskets. The temperature resistance reaches up to 450 degrees Celsius with a pressure resistance of up to 320 bar. The temperature or pressure resistance of a spiral-wound gasket mainly depends on the material composition.
- 200 to + 280
- 200 to +450
- 40 to +900
-40 to +1000

Definitely. It depends on the material combination of filler and stainless steel strip when it comes to a spiral-wound gasket`s heat-resistance. In addition, selected chambering influences the temperature resistance as well. In order to find the right material combination and temperature, contact us. We will be happy to advise you!
Yes. Spiral wound gaskets with inner and outer rings are standardized. The seal itself can be manufactured in all sizes. Each country has its own standards. They are listed in the centering ring table. Most common standards for spiral wound gaskets are the American, the English and the European standards.
Spiral wound gaskets particularly fit difficult operating conditions such as: high pressure, pressure fluctuations or high temperatures. In the industry, spiral wound gaskets are used in the following exemplary areas: chemical plants, refineries, chemical industry, pipelines, tanks, power generation, power plants, steam boilers, pollutant incineration plants, flanges, covers, manholes and many more.
