Pure expanded mineral graphite laminated.
Due the natural characteristics of graphite this is a high quality
material with an universal use in high pressure and temperature
services. Excellent resistance to steam. Meets most refinery, petrochemical
and industrial service requirements for long time periods and a
wide range of temperatures.
Three different grades are manufactured:
BELPAGRAF SL/GL: pure mineral expanded graphite laminate.
BELPAGRAF SR/GR: laminate with flat 316/316L stainless steel insert
(0.05 mm thick). Recommended for steam applications.
BELPAGRAF SE/GE: laminate mechanically bonded to a 316/316L stainless
steel tanged insert (0,1 mm thick). Grade for high pressures and
temperatures.

1- Usually satisfactory to use without reference to Montero.
Technical examination is normally unnecessary.
2- Must refer to Montero for advice. A technical examination
is recommended
3- Area not recommended.
The P-T diagram helps the user or designer who often knows
the operating temperature and pressure to carry out an initial
selection of a suitable material . The P-T diagram cannot
guarantee the suitability of a material for an application
