Cutting spiral crooked and fighting the connection
A crooked cut on spiral pipe creates an uneven end that will not seat fully around the joint. Correct the cut before fastening, or the joint will leak on the high side.
Ask when finish/exposed spiral, connection type, seal method, support, or fitting orientation is unclear.
Watch out
Do not force a crooked-cut spiral joint into place with fasteners. The uneven engagement will leak and the fasteners will not hold evenly.
Check
Look at the cut end face-on and check whether the edge is square to the pipe.
If the cut is only slightly crooked and you still have enough length, trim it clean and square before trying the joint again.
For a larger crooked cut, re-mark the pipe with a wraparound guide and re-cut the end cleanly.
Deburr the edge after re-cutting before seating the joint.
If the pipe becomes too short after correction, use the spiral short-cut recovery route instead of forcing it.

Say this to your foreman
I cut this spiral piece crooked and it will not seat properly. I can re-cut it, but I will lose about inches of length. Is that okay, or do we need a new section or approved coupling/spool recovery?
