1.5" NPT Pressure Rating
1.5" NPT Pressure Rating
(OP)
Hi,
I am trying to find the pressure rating of 1.5" NPT Threads. I have been looking at the net and I was able to find the rating for threads smaller than 1". I am using the 1.5" NPT at a temperature of 200 degree C. Can you assist me with finding the pressure rating and the derating factor for the temperature specified.

I have been using NPT threads for a while and the NPT Connections have always come with some pressure rating. I have the below link with the pressure rating for the NPT threads. This goes upto 1" only.

Your link shows compression fittings. The pressure retaining capacity of those have little to do with their threads. The bulk of the pressure is retained by brute force wedging of metal to metal faces against eachother. The threads simply provide the mechanical means of reaching the force necessary to do so.
