@Ollie. If the answer lay in the specs then I wouldnt have to ask the question or if there were underlying circumstances like a withdrawl length etc.. i wouldnt need to either. The reason I asked is because I need to make a turn in a short space, ie. a 60mm PUP piece would suit me perfectly, if not then i got ot look at an alternative. The specs dont give the answer, so i turned to 2 senior pipers one of the my lead and posed the question, 2 different answers i got, none of them wrong but none of them right for my situation. The decision has been basicaly left to me.
As for as i am concerned the ultimate governing factor is the welds and the minimum distance between the welds, while taking into the consideration the shops ability to fabricate it. I believed this length to be 50mm. So I tried to find something to back it up. So i pose the question here to find info. Im not going to turn around when asked why I made it 60mm and say i read it on piping designers.com, give me some credit.
If on this forum I get similar answers that seem to agree with my thinkling then i will investigate some thing that backs my decision.
The point I am making is, you have to respect peoples questions, you have to assume they looked in the specs, assume they have asked a lead or a more senior designer(unless the question screams novice or they are known to be a novice), were not stupid and lets face it no designer knows evertything there is to know about piping off the top of there head. So comments like did you skip the piping course are not helpful. So unless your comment is helpful or genuinely funny keep them to your self.
