Hi :
I did post this in Gas piping forum, But i think it should be here, the question is:
How far is an open flame (water bath heater) can be placed from above ground NG piping flange connection, taking into consideration: we have a tight area, and there is no leak except in an abnormal conditions (Class I, Div 2)
And how to document this finding in the way of calculating the LEL of NG in a radius of x', knowing that I have the gas line pressure.
Thanks for your prompt feedback
