The inspection and evaluation of cylinder mounting threads are governed by Compressed Gas Association C-23, which provides criteria for assessing thread wear, local thin areas, and structural integrity. These requirements are mandated under PHMSA regulations (49 CFR Part 180), ensuring periodic inspection of high-pressure tubes used in transport. Additional guidance on structural assessment is provided by ASME FFS-1, while general inspection practices are outlined in CGA C-6 and ISO standards.
