AVKO® manufacture and offer ready made flat gaskets
from that material.
CHARACTERISTICS
Non asbestos sealing sheets, manufactured from expanded graphite with tanged steel
reinforcement, made from SS316.
Application
Tregraph® sheets are used for sealing of flanges, contact surfaces, covers, heat-exchangers, etc. It is the best material for sealing of steam, hot steam, hydrocarbons, etc.
Advantages
TREGRAPH® sheets have following advantages:
- Excellent resistance to high temperatures and loading in combination with high internal pressure of fluid;
- Chemical resistance to media with рН 0 ÷ 14: hot water, oils, hot steam, , gases and ashes, sulphades, etc.;
- Excellent heat conductivity;
- Radiation resistance;
- Long term elasticity, material is not aging;
- TREGRAPH® sheets are 2 times less dense (1,1 ÷ 1,2 гр/см3) comparing to the polymer or conventional
fiber sheets (1,8 ÷ 1,9 гр/см3). In result end user has economy of material.
- Reinforcement with tanged steel ensure better resistance of material to high internal pressure, tha steel
mesh, used in other sealing sheets.
