Spiral-wound gaskets offer high resistance to the pressure inside piping.

Spiral Wound Gaskets

The robust metal construction composed of three different elements ensure high pressure resistance to a spiral wound gasket.

The right material usage guarantees first-class chemical resistance, wide range of pressure, and temperature capabilities.

A spiral wound gasket is extremely suitable to be used in cyclical circumstances with its unique reversibility.

We manufacture spiral wound gaskets according to standards or to any of your requirements.

FAQ

Spiral Wound Gaskets

Various materials can be used in spiral wound gaskets. Carbon steel, AISI 304 (L), AISI 316 (L), Monel or Inconel are used for winding, outer and inner ring. Graphite, PTFE, or Thermiculite are often used as the filler.
Most commonly the outer ring is made of carbon steel, winding and inner ring from AISI 316 (L), and the filler is graphite.
Usually, a spiral wound gasket is composed of an outer ring, winding, filler, and inner ring according to EN 1514-2 type C/I.

In some cases, there is no need for an inner ring or for neither outer or inner rings.
Commonly the thickness of a spiral wound gasket is 3.2/4.5 mm. It means that the outer and inner rings are 3.2 mm, and the tape is 4.5 mm.

In special cases, the thickness might be 3.2 mm but then the gasket is composed only of tape and filler.

In a flange connection, the spiral wound gasket can be tightened to a final thickness near 3.2 mm, which means that the gasket is not reusable.

Example Use Cases

You can use spiral wound gaskets in many different applications. To give you a better idea, we’ve featured example use cases below from a power plant, a pulp factory, and an LNG vessel.

TT Gaskets - We supply gaskets for power plants

Power Plant

The requirements for sealing applications in the energy industry are very demanding and spiral wound gaskets excel especially when used in steam lines.

Pulp Factory

The handling processes in this industry typically require a lot of machine power and various types of automated lines.

With this much muscle power in use, you cannot afford your gaskets to let you down.

Spiral wound gaskets are a great choice to be used in batch cooking and in pipelines with high temperature and pressure.
