North Dakota Administrative Code › Title 33.1 - Department of Environmental Quality › Article 33.1-14 - NORTH DAKOTA BOILER RULES › Chapter 33.1-14-01 - DEFINITIONS › Section 33.1-14-01-01 - Definitions

Current through Supplement No. 393, July, 2024
As used in this article:
1. "Alteration" means a change in an item
				described on an original manufacturer's data report which affects the pressure
				retaining capability of the pressure retaining item. An alteration includes
				nonphysical changes, such as an increase in the maximum allowable internal or
				external working pressure, an increase in design temperature, or a reduction in
				minimum temperature. For boilers used in the power generation industry
				exceeding one hundred thousand pounds of steam per hour output, increases in
				steaming capacity may not be considered an alteration if a new baseline
				steaming capacity is established based on either an engineering evaluation or a
				review of the operating history and a conditional assessment of the boiler and
				its components. An engineering evaluation or conditional assessment must be
				made by the boiler owner with review and comment by the authorized inspection
				agency responsible for the in-service inspection of the boiler. Engineering
				evaluations and conditional assessments are subject to the review and approval
				of the chief boiler inspector.
2.
				"Apartments" means all multiple dwellings, including condominiums.
3. "Approved" means approved by the
				director.
4. "A.S.M.E. code" means
				the boiler and pressure vessel construction code of the American society of
				mechanical engineers of which sections I, II, IV, V, VIII (divisions 1, 2, and
				3), IX, and X, 2021 edition, are hereby adopted by the director and
				incorporated by reference as a part of this article. A copy of the American
				Society of Mechanical Engineers Code is on file at the office of the boiler
				inspection program. The American Society of Mechanical Engineers Code may be
				obtained from the American Society of Mechanical Engineers headquarters at 2
				Park Avenue, New York, New York 10016-5990 or from
www.asme.org
.
5. "Boiler" means a closed vessel in which
				water is heated, steam is generated, steam is superheated, or any combination
				thereof, under pressure or vacuum for use externally to itself by the direct
				application of heat from the combustion of fuels or from electricity or nuclear
				energy. The term boiler includes fired units for vaporizing liquids other than
				water when these units are separate from processing systems and are complete
				within themselves, as provided under subsection 1 of North Dakota Century Code
				section 23.1-16-01.
6. "Certificate
				inspection" means an inspection, the report of which is used by the chief
				boiler inspector to decide whether a certificate may be issued under North
				Dakota Century Code section 23.1-16-10.
7. "Certificate of competency" means a
				certificate issued by a jurisdiction indicating that a person has passed an
				examination prescribed by the national board of boiler and pressure vessel
				inspectors.
8. "Chief inspector"
				means the chief boiler inspector appointed by the director to serve in the
				capacity as stated by law.
9.
				"Condemned boiler" means a boiler that has been inspected and declared unsafe
				or disqualified by legal requirements by an inspector qualified to take such
				action who has applied a stamping or marking designating its
				rejection.
10. "Deputy inspector"
				means a boiler inspector or inspectors employed by the director to assist the
				chief inspector in making inspections of boilers.
11. "Director" means the director of the
				department of environmental quality.
12. "Existing installations" includes any
				boiler constructed, installed, or placed in operation before July 1,
				1973.
13. "External inspection"
				means an inspection made when a boiler is in operation.
14. "Fusion welding" means a process of
				welding metals in a molten or molten and vaporous state, without the
				application of mechanical pressure or blows. Such welding may be accomplished
				by the oxyacetylene or oxyhydrogen flame or by the electric arc. Thermic
				welding is also classed as fusion.
15. "High-pressure, high-temperature water
				boiler" means a water boiler operating at pressures exceeding one hundred sixty
				pounds per square inch gauge [1103.17 kilopascals] or temperatures exceeding
				two hundred fifty degrees Fahrenheit [121.16 degrees Celsius]. For practical
				purposes it must be deemed the same as a power boiler.
16. "Hot water supply boiler" means a fired
				boiler used exclusively to supply hot water for purposes other than space
				heating and includes all service-type and domestic-type water heaters not
				otherwise exempt by North Dakota Century Code section 23.1-16-06.
17. "Inspector" means the chief boiler
				inspector or any deputy inspector or special inspector.
18. "Internal inspection" means an inspection
				made when a boiler is shut down and handholes and manholes are opened for
				inspection of the interior.
19.
				"Low pressure and heating boiler" means a boiler operated at pressures not
				exceeding fifteen pounds per square inch gauge [103 kilopascals] for steam or
				at pressures not exceeding one hundred sixty pounds per square inch gauge
				[1103.17 kilopascals] and temperatures not exceeding two hundred fifty degrees
				Fahrenheit [121.1 degrees Celsius] for water.
20. "Major repair" means a repair upon which
				the strength of a boiler would depend. Major repairs are those that are not of
				a routine nature as described in the National Board Inspection Code.
21. "Miniature boiler" means any boiler that
				does not exceed any of the following limits:
a. Sixteen inch [40.64 centimeter] inside
				diameter of shell.
b. Twenty square
				feet [1.86 square meter] heating surface.
c. Five cubic feet [.142 cubic meter] gross
				volume, exclusive of casing and insulation.
d. One hundred pounds per square inch gauge
				[689.48 kilopascals] maximum allowable working pressure.
