How much length does a pipe fitting add?
The length must include the distance between the fittings and the extra reach that goes into the fittings. If you are using 1/2-inch pipe, add 7/16 inch per end; and add 1/2 inch per end for 3/4-inch pipe.
How do you calculate fitting allowance?
An accurate dimension from the end of the nipple to the centre of the outlet is then measured. This is repeated for each of the nipples. The difference between the end-to-end measurement and the end-to-centre (of the 90) measurement is the fitting allowance.
How far does black iron pipe thread into a fitting?
With a new fitting, turn the pipe until only three threads are visible. If you have to remake the fitting, add a few turns to get a tight fit. However, the pipe should never penetrate so far into the fitting that all the threads are covered.
How much thread allowance should you allow for a 1 inch pipe?
1/2-inch and 3/4-inch nominal pipe size have 14 threads per inch. 1-inch, 1 1/4-inch, 1 1/2-inch and 2-inch nominal pipe size have 11 1/2 threads per inch. 2 1/2-inch nominal pipe size and larger have 8 threads per inch.

How do I determine the theoretical fitting allowance for a pipe?
Once students have experimentally determined a consistent fitting allowance for the pipes they were working with, the teacher can share manufacturer’s documentation that indicates the theoretical fitting allowance. Many sources for this can be found within manufacturers’ documentation.
