Threaded Pipe Installation
(OP)
Where can I find the minimum and maximum installation torque for NPT threaded pipe? Is there a pipe-fitters manual somewhere? I need this for the design of the threaded body/adapter joint on our threaded-end ball valves.

If I were able to fracture your valve with the amount of torque I could exert through a good pipe wrench's teeth, with a handle of arbitrary length, without stripping the outside surface off the pipe, I'd speak ill of your valve.
