Another good point, look at it like flanges, match the schedule of pipe. The K.I.S.S. method. Do you have a link to that chart you referenced, and does it give reference to a specific code. I am just trying to find proof of this logical deduction, do you have a table linking the sch to the...
Good point. It does seem odd though that they would classify these fittings in such an abiguous term if that was to be considered though, wouldn't it. And if it was already considered you would think it would be a worst case consideration wich should eliminate me from even worrying about this...
Yes, but what is one required to do when in the SAME piping system the pipe schedule increases, like 1" pipe needs S160 (supposed to use 6000# fittings) and 1-1/2" pipe calls for Sch80 (supposed to use 3000# fittings). Should the fitting rating jump to 6000# just because the pipe wall...
Thank you for your input, it did seem logical but I wanted a second opinion. Now I have another question you would probably be able to help me with as well. What are the actual working pressures for forged fittings? ie 2000#, 3000# ,6000# & 9000#. I know this may sound stupid but I have been...
I am aware that there is a matching pipe wall thickness for a given class of socket weld fitting (Sch80/XS pipe goes with a 3000# class socket weld fitting for example) My question is if that is a requirement in B31.3. In other words am I allowed to use, say Sch 160 pipe in a 3000# fitting...
