ERIKS RX® Firechem®
RX® Firechem® Flange Gasket
The innovative material combination of pure exfoliated graphite (min 98%), reinforced with stretched stainless steel, and expanded PTFE. RX® Firechem® complies with the strongest requirements of the FIRE-safe test ISO 10497 and can also be placed in contact with the most versatile, aggressive and flammable chemicals. RX® Firechem® solves the problematic combination of high chemical resistance and fire security, required by the SEVESO directive.
Application
- Resistant to all media in the range 0 to 14 pH. At the exception of molten alkali, fluor and fluorinated gasses particularly at high pressures and high pressures.
- Ideal for worth flange conditions.
- Excellent results where low bolt loads are available for instance in low pressure class flanges.
Delivery standards
Can be manufactured in all dimensions and forms: Standards to EN1514-1, EN12560. Non-standard as frames, oval manhole, heat-exchanger gaskets and all complicated shapes. Can be produced in very short time. Tolerances to DIN 7715-5-M.
Approvals
Fire safe ISO 10497 (replaces BS6755, API 607)
DVGW: Natural gas
KTW : potable water
BAM: Oxygen
Features
- unique combination
- quick supply production
- very large application fields
- soft gasket
- patent pending
All possible shapes can be manufactured in no-time. Everything is possible, even within one hour shipping of a finished gasket. Applicable in chemical as petrochemical where security is prior. RX® Firechem® can perfectly be used where low bolt and gasket stresses are present. This is particulary the case in low pressure flanges like PN 10/16 and 150/300 lbs.
