I am looking to find the maximum weight that can be put on a 2" schedule 40 PVC pipe.
I have to move a 12 x 24 shed about 25' & turn 90 degrees. Any help hill help.

The question you asked form what I seen is not answered often Engineering liability even an engineer would hesitate his Lic.. would be at risk. Yes I can help If I assume you are using the pipe for rollers and not a skid/ski setup. I moved a lot of boilers on pipe and many other things big hot tubs /sheds etc a house. Here's how this works. The real question is HOW MANY PVC pipes do I need. What ever your moving/ basically rolling is about how far can you move that object before the moving front ends digs into the ground and stops the movement because of grade change or it gets out of balance. Then it becomes how well does the pipe you put under the shed stay spaced as it rolls and doesn't jam up. When you are rolling it's a bit of a hit and miss Buy extra pipe in case you need to add more rollers because rollers jam up.( can always return if not used) If you space the pipe about 4 or 5 feet apart perpendicular along the 25' part this should be fine. I would lay down planks spaced on the ground for the rollers to roll on instead of dirt a smoother ride. Now if you are trying to skid it use about the same dimensions of spacings to skid. The skidding will need 2bys on ground perpendicular to skid across. I am sure a lot of this you are ready thought of and maybe know But it the pipe roller method is tried and true, sometimes we crack a pipe just jack another one in. I am not an engineer but I have engineered a lot of riggings. Field test is always first In thought if you can put 60 psi in a schedule 40 pipe in convex pressure think of the reverse like how a wheel or egg can take outward pressure and transfer it to it outer points. May be that thought will ease your thoughts. P.S. I have to apologies I just re read you post and saw 2" My mind went into auto pilot because I have done many times what you are doing as a contractor. My spacing was based on 3"PVC Sch 40. Back to the PVC I personally wouldn't,t use 2" its wont roll well and gets jammed and you will need tighter spacing its sags more also. I know its a lot more money for 3' Sch 40 I have accumulated a lot of it and that whats easily available to us. I don where you live there is also a 3" schedule 30 PVC that's used on in sewer line that cheaper than forty. What ever you think 3" 30 would work a lot better than 2" 40 for rollers. But If this is a contracted job how much is extra labor in time Pulse the fact
I hope this answers your well enough Let me know If you need more Info!

Have a nice Christmas Contracting! signed 21boat
