TSSA posted a new guideline outlining the steps for implementing the Alternate Process for Pressure Piping.
 
The Alternate Process for Pressure Piping Inspection allows eligible companies to inspect certain pressure piping systems using their own TSSA‑accepted Qualified Persons as an alternative to a TSSA Inspector, while maintaining TSSA oversight through audits and technical reviews.
 
The guideline provides clear directions on the Alternate Piping Process, including:

  • How to obtain a TSSA Certificate of Authorization (COA) for the Alternate Piping Process

  • Requirements for qualifying and appointing qualified persons to conduct alternate piping inspections on eligible piping systems

  • How to notify TSSA of Alternate Piping Process jobs

  • How to submit the Alternate Piping Data Form

  • Annual audits of the Alternate Piping program

The requirements around submitting work orders have been updated and are clearly defined in the new guideline. Please review and follow the revised requirements, particularly the updated Section 7 on Alteration Piping Work Orders and Section 8 on the specifics of work orders.
 
For more information, please read the Guideline for the Alternate Piping Process.
