GTL-SPW200 Spiral Wound Gaskets

Description： Spiral wound gaskets have the ability to recover under the action of fluctuating loads caused by process fluid pressure and temperature changes, flange face temperature variations, flange rotation, bolt stress relaxation and creep. The gasket sealing element consists of a pre-formed metallic winding strip with layers of a softer, more compressible sealing material which, during compression, is densified and flows to fill imperfections in the flange surfaces. The metal strip holds the filler giving the gasket mechanical resistance and resilience.

DETAILS

Application:

1.Spirals wound gaskets are widely used in piping and pressure vessel flange connections, in medium to high pressure and temperature duties.

2.The sealing element of a spiral wound gasket is manufactured from a preformed metallic strip in combination with a soft filler material.

3.Inner and/or outer rings can be incorporated to suit the flange face design and application parameters.

Materials:

1.Sealing element winding strip: Austenitic and duplex stainless steel grades as well as other exotic alloy steels.

2.Sealing element filler material: Flexible graphite, PTFE and mica.

3.Custom sized gaskets can be produced from customer supplied information.

4.Three standard sealing element thickness options are available, i.e., 0.125", 0.175" and 0.250". Other thicknesses are available on request.

When ordering , please specify Inner ring material , Winding materials , Outer ring materials , Size , Class and Quantity.
