About ASME B31Q

The American Society of Mechanical Engineers (ASME) has been a leader in pipeline safety since 1922.
B31Q is ASME’s standard for Pipeline Personnel Qualification, which contains over 150 tasks in pipeline safety and integrity.

The B31Q Task List specifies the requirements for:

  • Identifying covered tasks that impact the safety or integrity of pipelines,
  • Qualifying individuals to perform those tasks, and
  • Managing the qualifications of pipeline personnel.

Careful application of ASME’s B31Q code helps users comply with applicable regulations within their jurisdictions, while achieving the operational, cost, and safety benefits to be gained from the many industry best-practices.
