ASME PCC-1 2022

ASME PPC-1 is a standard developed and published by the American Society of Mechanical Engineers (ASME) that provides bolted flange joint assembly (BFJA) guidelines for pressure-boundary flanged joints. ASME PCC-1 was originally published in 2000 as a guideline to industry and has since been elevated to an industrial standard for bolted flange joint assembly.

Appendix A was developed in response to a need expressed by some in the bolting services industry. It provides guidelines for establishing uniform criteria for training and qualifying bolted joint assembly personnel. It also provides guidelines for quality control of the programme.

Appendix A contains guidance for the levels of training and experience required for technicians working on BFJAs. There are now three major levels of qualifications: qualified bolting specialists, qualified senior bolting specialists, and qualified senior bolting instructors. All three levels require different degrees of training, experience and assessment.

Since being elevated to a standard from a guideline for the most recent publication, several oil/gas and petrochemical sites across the UK have taken this as their site wide mechanical joint integrity qualification for their own personnel and contractor labour working at site.

The training course is a combination of theory and practical exercises and assessment, also work based assignments.
