1. Which of the following best describes a Minnesota high pressure
piping system under the Minnesota Department of Labor and
Industry requirements?
A. Any water piping operating above 80 psi
B. Any steam system operating above 5 psi
C. Steam-system piping designed to operate at more than 15 psi
D. Any domestic water system operating above 100 psi
C. Steam-system piping designed to operate at more than 15 psi
Minnesota defines high pressure piping to include steam-system piping
designed to operate at more than 15 psi, as well as certain high-
temperature heating, ammonia refrigeration, and bioprocess piping
systems.
2. Before a Minnesota high pressure piping contractor can obtain a
permit for high pressure piping work, which fundamental licensing
requirement must be satisfied?
,A. The contractor must employ a licensed master pipefitter
B. The contractor must employ only registered apprentices
C. The contractor must obtain a plumbing contractor license
D. The contractor must register as a residential building contractor
A. The contractor must employ a licensed master pipefitter
Minnesota requires a high pressure piping contractor to first employ an
individual holding a master pipefitter license before the business can
obtain its high pressure piping contractor license and subsequently
apply for permits.
3. Which person is primarily responsible for serving as the qualified
master-level pipefitting individual associated with a Minnesota high
pressure piping contractor?

C. A licensed master pipefitter
The Minnesota contractor licensing process requires the business to
employ an individual who holds a master pipefitter license before the
business may obtain the high pressure piping contractor license.
4. Which Minnesota agency administers licensing requirements for
high pressure piping contractors and individual pipefitters?
,A. Minnesota Department of Transportation
B. Minnesota Department of Labor and Industry
C. Minnesota Department of Commerce exclusively
D. Minnesota Pollution Control Agency
B. Minnesota Department of Labor and Industry

Minnesota specifically identifies ammonia refrigeration-system piping as
high pressure piping, along with qualifying steam, heating, and
bioprocess piping systems.
6. A contractor is installing a heating-fluid piping system designed to
operate at 275°F and 35 psig. How should this system generally be
classified under Minnesota's high pressure piping definition?
A. Ordinary low-pressure piping
B. High pressure piping
, C. Domestic plumbing
D. Residential water service
B. High pressure piping
Minnesota identifies heating piping carrying high-pressure and high-
temperature fluids designed to operate above 250°F and 30 psig as high
pressure piping.
7. Which code is identified in Minnesota's current high pressure piping
examination guide for steam or heating-media piping systems?
A. ASME B31.1-2020
B. ASME B31.3-2018
C. ASME B31.8-2022
D. ASME B31.9-2020
A. ASME B31.1-2020
Minnesota's high pressure piping examination guide identifies ASME
B31.1-2020 as the Code for Steam or Heating Media Piping Systems
incorporated into the Minnesota high pressure piping code.
8. Which standard is identified for ammonia refrigeration systems in
Minnesota's high pressure piping examination materials?
A. ASME B31.1-2020 only
