Crashtested, I appreciate your answer. I also learned the same method of hidden lines in my years of schooling. But, after much arguing and debating with other designers with spans of experience, our company has come to a conclusion.

Any time we’re doing a piping plan, we’re showing u/g lines as a hidden linetype, which wasn’t debated. And drum roll please….any time we’re doing a piping elevation (say, at a riser outlet), we’re showing u/g lines as a continuous linetype.

My arguement was that if you’re showing a section view with grade, or dirt, in between the section and the actual piping, then the piping would be hidden linetype because the dirt is in front of it. But, apparantly when showing a section, we’re assuming that the section view takes place right in front of the piping, which means there’s no dirt in front of the view. According to many, it has been done like this for years by several different company’s which makes it “industry standard”. Personally, i don’t really care, i just wanted a typical way of doing it.

these people are making it more complicated than it is. It’s Very simple.
Connect a 300 rating flange to the 300 rating nozzle. Then weld 150 rating pipe to the 300 rating flange. If the schedules don’t match, change the schedule of the 300 rating flange to be the same as the schedule of the pipe (why? becuase the schedules of a weld should match on both sides of the weld for welding easablitiy).
