Maximum Temp. that a 2 NPT (Pipe Thread) can withstand.

    Maximum Temp. that a 2" NPT (Pipe Thread) can withstand.

    Hello Forum
    I have a question related to Pipe threads. Does anybody know the maximum temp. a NPT Thread i.e,( National Pipe Thread) can withstand on a 2" piping without compromising its performance. It has 11-1/2 TPI (Threads Per inch)
    Any references, vendors, personal experiences that can help. The pipe carries 'hot gas' in it.

    Thanks in advance

    I would say it depends more on the material than the fact that the material is threaded.

    It depends on the material of construction of the pipe....

    Is it stainless steel? Temp rating will be high

    Carbon Steel? It will be a lot lower.

    Then you can look up a chart that will tell you the max temperature rating.
