No reciprocity appears in the boiler-program rule. The experience standards (2,000 hours of B31 pipe-welding + 2,000 on pressure piping for Class 5) accept documented out-of-state hours by employer verification, then Oregon’s own exam issues the card. Open “Bringing your license from another state” below for the conditions, and confirm with the board before you travel.

Bringing your license from another state
Nothing transfers — and almost nobody knows Oregon licenses this trade at all, because the cards live in the BOILER PROGRAM, not with the plumbers: Building Codes Division licenses, class by class, including a Class 5 PRESSURE PIPING MECHANIC and a Class 5-A PROCESS PIPING MECHANIC (ASME B31.3 by name). No reciprocity appears in the rule.
What travels is your HOURS: the experience standards accept documented out-of-state work by employer verification, and then Oregon's own exam issues the card.
Can you work while it is pending?
The CLASS 1 TRAINEE/HELPER license is the lawful work-while-qualifying lane: no experience prerequisite, supervised mechanical work on boilers, vessels and piping — no ASME code welding — applied for on the same form as the working classes. No other pending-application provision was found; do not start on silence above Class 1 scope.
The exam and the hours
Match the class to the code you work: CLASS 5 (pressure piping) takes 2,000 hours of pipe-welding on ASME B31 pressure piping plus 2,000 hours on pressure piping and boilers; CLASS 5-A (B31.3 process piping) and CLASS 5-B (B31.5 refrigeration piping) run the same shape on their own codes; CLASS 6 is the welder's card — current ASME Section IX qualification, working for an approved employer.
File the boiler license application with a verification form from EACH employer whose hours you claim, wait for BCD's authorization letter, sit the exam; results come by mail within two weeks.
How apprenticing works here
Class 1 is the entry license — no experience required, supervised, non-welding. Registered apprenticeship runs alongside as the training system, but the BCD class license is the legal instrument on the work.
The local picture
None — the boiler program is statewide; municipalities handle building permits.
If you want to contract for yourself
The business side is CCB contractor registration plus the boiler program's permits — and the worker-side classes above are what put your people on the pipe legally. One boundary worth a call on unusual jobs: the licensing duty attaches through Oregon's boiler and pressure-vessel law, so for a standalone piping job with no boiler or vessel in sight, confirm with BCD which class the permit demands before quoting.
Plumbing scope (potable, waste) is the separate journeyman plumber program.
