For flanges according to ASME to be observed:
- Gasket type: flat gasket tanged sheet metal/graphite or similar
- Gasket dimensions: according to ASME B16.21
- Seal data: design seat tension
Y

= 2.5
When flange seals which protrude into the pipeline are used for turbine me-
ters, the measuring accuracy can be influenced negatively. Ensure that the
flange seals do not protrude beyond the seal surfaces into the pipeline.
Gas escape due to incorrect seal
If incorrect flange seals are used for the assembly of turbines, an explosive
gas mixture can form due to leaks.
Danger of poisoning and explosion!
In addition, the stress on the flange is increased to an impermissible level
when tightening the thread bolts.
Ensure secure fastening/attachment of the TME400 during assembly in order
to avoid crushing. Ensure that you keep your fingers (or other body parts)
away from these openings and gaps when pulling the flanges together.
