PRODUCT
REFERENCE:
FLEXICARB RGS 4
DESCRIPTION:
RGS 4 is a high purity graphite laminate reinforced with a flat stainless steel
core.
SERVICE:
FLEXICARB RGS 4 is recommended for high temperature, high pressure sealing
applications. The inclusion of the steel reinforcing core gives rise to a robust
sheet with excellent handling characteristics. RGS 4 can be used to seal a wide
range of media, with the exception of strong oxidising agents, at extremes of
temperature and pressure. The soft conformable nature of the graphite facing
material makes RGS 4 suitable for sealing between worn or pitted flanges. Typical
industries where RGS 4 is used include power generation and petrochemical.
Maximum recommended temperature :
Oxidising media 370OC (700OF)
Inert or reducing media 700oC (1290oF)
Maximum recommended pressure :
15 MPa (150 bar; 2200 psi)
Note : For applications sealing inert or reducing media, at temperatures in excess
of 370OC, attention must be given to the possibility of oxidative attack on the
gasket from the external environment.
Use with strong oxidising agents should be avoided.
For long term continuous use in oxidising environments at temperatures in excess
of 370OC please consult Flexitallic Applications Engineering Department.
