Hello All,
I have a question regards range of diameters when qualifying a PQR, if I run a PQR on 300NB STD pipe will the DIAMETER range on the WPS be unlimited. As long as the welder is qualified using the right diameter pipe for the job.
Example: if I was to do a PQR on 300NB pipe as long as the thickness was in range I than could use that PQR to weld 80Nb pipe? it is the position and thickness that has a range not diameter? NON CVN application.
Thanks all
