was tested in respect of fire safety. The test was made under the following

Total bolt load: 806 kN
Burn period: 30 min
Average temperature calorimeters: > 650 °C
Test pressure (absolute): 40 bar
Test medium: Water
Leak rate complete test: 0.00 mI/(inch – min)
Leak rate pressure test: 0.21 mI/(inch • min)

After the burn period the connection was air cooled to a flange temperature below 100 °C. During the cool down the connection was still pressurized with the test pressure. Afterwards a pressure test for 5 min was done.

Therefore the gasket is in compliance with the tightness criteria of 1 ml/(inch • min) of API Specification 6FB during burn period, cool-down and pressure test. The gasket manufacturer can mark the gasket as “Fire Safe” in accordance to the specification API Specification 6FB.”
