How much do you guys add to lenghts for threaded pipe?
The rule of thumb my pappy taught me is the fitting allowance is basically the same as the pipe you are threading. So if I were to need a piece of 3/4″ pipe to fit between two holes 12″ on center, then the actual cut and threaded piece would be 12 inches, minus 1-1/2″, or 10-1/2″ end to end.
How big should fitting allowance be for close rough pipe?
With close rough, the fitting allowance is typically one pipe size less than the pipe you are dealing with. So, using the same example above, and using long radius tees, the fitting take off, or allowance would be the same, so the pipe end to end would be 10-1/2″.
How big should pipe be for close rough elbow?
Using the same example, but using close rough elbows, the fitting allowance per fitting would be one pipe size less than the actual pipe size, so 1/2″ x 2 would be 1″ take off for close rough, or 11 inches end to end. What gets tricky is when you are using a reducing elbow.
How do you measure the distance between pipe fittings?
Measure the center-to-center distance between the two pipes and subtract the total of the laying lengths of the fittings at both ends. The table below shows the socket depth for threaded steel pipe.
