Braided tape with High Temperature Inconel mesh reinforcement
A 66 Incograph HT
Braided of Flexible Expanded Graphite Tape with high temperature resistant Inconel-mesh reinforcement
Characteristics
- Universal plant wide use in static applications
- Extrusion stability through ultrafine 10 myh Inconel mesh reinforcement on each strand
- Non hardening, good reset capability, coefficient of thermal expansion corresponds to the coefficient of steel
- High temperature and pressure resistance
- Easy to cut, assemble and disassemble
- Low coefficient of friction minimizes the adjustment force in valves
- For valve applications rings should be approx. 25 - 30 % compressed at installation
- A 66 can be used as bullrings for style A 44, A 44 I, P 60 and ARF
- Die formed rings are recommended
