During the normal service life of a cylinder, thread wear and damage, particularly to the external threads, are to be expected.

Per the stipulations of 49CFR Part 180.212, CP Industries, as a cylinder manufacturer working under supervision of an independent inspection agency, is authorized to perform re-threading of DOT and UN specification containers. CP Industries is also authorized to perform similar work on ASME vessels under the terms of our ASME “R” (repair) stamp. These capabilities can dramatically extend cylinder service life.
