Filler/Facing Materials for Metal GasketsFiller/Facing Materials for Metal Gaskets

Description and Applications

In addition to the filler/facing materials offered in the metallic gasket product section, TEADIT® offers the following high temperature materials.

SGL® SIGRAFLEX Type APX2 Flexible Graphite

Flexible Graphite with advanced oxidation inhibition & excellent sealability

MICA

Phlogopite Hi-Temp grade to 1832°F (1000°C). Used in some hot gas applications, and as filler/facing for spiral wound & camprofile gaskets and as an oxidation barrier in combination with other sealing materials.

Ceramic Fiber

Used in some hot gases/ low pressure service. This material is also used as filler for metallic gaskets or in combination with other sealing materials. Temperature limit: 2000°F (1090°C).

XHR

Extreme heat resistance. Uses combination of mica barriers and APX2 to provide exceptional sealing ability to 1500°F (815°C).

PTFE

Polytetrafluoroethylene provides superior chemical resistance and great sealing ability. Typically rated to approximately 500°F (260°C).

Flexible Graphite

Provides soft conforming material in fire-safe design with excellent chemical resistance. Typically rated to 842°F (450°C).

Developing A Special Camprofile Gasket For a Pressure Vessel

Style 2007 in Chemical Slurry

A chemical processing facility was having issues maintaining adequate sealing on a slurry pump with their existing packing, requiring retightening every few hours.

Thermic Fluid Case History

Dual Packing Combination Kit in Sugar Industry

2774 and Sealpak® 46

2235 in Steam Application Case History

A chemical processing facility was experiencing steam leakage on a sulphonator vessel after only a couple of weeks of run-time leading to reduced efficiency in the process and longer required run times.

Teadit 24SH in Chemical Processing

A chemical processing facility was experiencing leaks on FRP flange connections due to damage to the flanges caused by the use of gaskets that were not suitable for the requirements of low strength flanges, like FRP.

Teadit Camprofile Gasket in Chemical Processing

A PTFE manufacturing facility was experiencing leaks on an FEP Extruder that was originally designed to utilize a metal reinforced compressed asbestos gasket.

ETP Copper Process Case History

A metal manufacturer was looking for a replacement for asbestos compression packing.

CMS Plant Case History

A chemical plant was having issues with skived virgin PTFE gaskets failing in a heat exchanger application.

2774 Harsh Chemicals Case History

A customer was using a PTFE packing from another manufacture in an auger conveyor system.
