Can PTFE gaskets be used in steam pipes at 250°C?

Considering the shape of the gasket groove and the type of gasket (whether reinforcement or additives are used), it is generally recommended to use a value of up to 200; as a more conservative figure, 150 can be used

It cannot be used; instead, the wound gasket for steel pipe flanges (PN series) specified in HGT 20610-2009 can be chosen

Generally, it’s not possible; usually it reaches 200, and conservatively it’s around 180.
