Or. Admin. Code § 918-225-0570 - Boiler and Pressure Vessel Inspection Schedules
Unless the division grants special permission, all inspectors must comply with the following inspection schedule:
(1) Power boilers must be inspected, at
minimum:
(a) Internally - every year, when
physical construction of the boiler allows; and
(b) Externally - every year, while under
pressure.
(2) Cast iron
boilers must be inspected externally - every two years, while under
pressure.
(3) Low pressure steam
boilers must be inspected, at minimum:
(a)
Internally - every two years, when physical construction of the boiler allows;
and
(b) Externally - every two
years, while under pressure.
(4) Hot water heating and hot water supply
boilers must be inspected:
(a) Internally -
every six years, when physical construction of the boiler allows; and
(b) Externally - every two years, while under
pressure.
(5) Pressure
vessels containing anhydrous ammonia intended for use as fertilizer must be
inspected, at minimum, externally every three years.
(6) Fixed pressure vessels, containing only
air, not located at a place of public assembly, not exceeding 20 cubic feet in
volume, and operated at gauge pressures of not more than 200 pounds per square
inch must be inspected, at minimum:
(a)
Internally - every six years, subject to section (13) of this rule;
and
(b) Externally - every six
years.
(7) Co2 vessels
and hydro-pneumatic pressure vessels, used for beverage service, not exceeding
20 cubic feet in volume, and operated at gauge pressures of not more than 300
pounds per square inch must be inspected, at minimum:
(a) Internally - every six years, subject to
section (13) of this rule; and
(b)
Externally every six years.
(8) Pressure vessels, not classified in
sections (5), (6), and (7) of this rule, and subject to internal corrosion or
erosion must be inspected, at minimum:
(a)
Internally - every two years, subject to section (13) of this rule;
and
(b) Externally - every two
years.
(9) Unfired
pressure vessels, not classified in sections (5), (6), (7), (10) and (11) of
this rule, and not subject to internal corrosion must be inspected, at minimum,
externally - every four years.
(10)
Unfired pressure vessels not subject to internal corrosion but containing a
substance which, if it were to leak, might cause serious irreversible harm to a
person must be inspected, at minimum:
(a)
Internally - every two years, subject to section (13)of this rule;
and
(b) Externally - every two
years.
(c) A substance "might cause
serious irreversible harm" if the substance's Material Safety Data Sheet
describes serious health or physical risks caused by short-term exposure to the
substance.
(11) Unfired
pressure vessels not subject to internal corrosion that are located at a place
of public assembly and are not classified in section (8) of this rule must be
inspected, at minimum:
(a) Internally - every
two years, subject to section (13) of this rule; and
(b) Externally - every two years.
(12) Pressure piping systems
containing refrigerants, steam, or pressurized condensate: Inspection during
fabrication, installation, repair, or alteration for verification of compliance
with material, welding, brazing, and structural support requirements. The
inspector may require other tests to verify quality of weldments. This rule
does not apply to welded repair of pressure piping under OAR
918-225-0720.
(13) The inspector may waive an internal
inspection, under section (6), (7), (8), (10) or (11) of this rule if the
inspector believes from alternate inspection methods an internal inspection is
not necessary to verify the safe condition of the vessel.
(14) An inspector may require additional
internal or external inspections, or tests, other than those required in this
rule, if the inspector has reason to believe that the boiler or pressure vessel
does not meet minimum safety standards.
(15) Failure to comply with sections (1)
through (14) of this rule may cause inspections to be performed by a deputy
inspector per ORS 480.570(6) as
directed by the chief inspector.
(16) The inspection schedule established in
this rule is summarized in Table 1-B.
