1. Where
				pressure reducing valves are used, one or more relief or safety valves must be
				provided on the low-pressure side of the reducing valve in case the piping or
				equipment on the low-pressure side does not meet the requirements for the full
				initial pressure. The relief of safety valves must be located adjoining or as
				close as possible to the reducing valve. Proper protection must be provided to
				prevent injury or damage caused by the escaping steam from the discharge.
				Capacity of the relief valves must be such that the pressure rating of the
				lower pressure piping or equipment shall not be exceeded in case the reducing
				valve sticks open.
2. The use of
				hand-controlled bypasses around reducing valves is permissible. The bypass if
				used around a reducing valve may not be greater in capacity than the reducing
				valve unless the piping or equipment is adequately protected by relief valves
				or meets the requirements of the high-pressure system.
3. A pressure gauge must be installed on the
				low-pressure side of a reducing valve.
4. All low-pressure headers and their outlets
				must be protected by a safety valve or valves whose combined capacity is
				equivalent to the total amount of steam that can pass from the high-pressure
				system to the lower pressure system.

Current through Supplement No. 393, July, 2024
1. No
				repair to any boiler or steam pipe nor any of the connections thereto may be
				approved which is made in whole or in part of unsuitable material or is unsafe
				from any cause. Nothing herein may be construed to prevent the use of any
				boiler constructed of riveted iron or steel plates when the inspector has
				satisfactory evidence that such boiler or steam generator is equal in strength
				to and as safe from explosion as boilers constructed of the best quality of
				materials.
2. Quality of the
				material used in boiler construction and repair demands critical attention
				because in performing its function a steam boiler is continually subjected to
				disruptive stresses. These are due to high internal pressures and to changes in
				temperature. Disastrous consequences will inevitably follow if the material
				fails under these stresses.
3. The
				quality of the material used in the different parts of a boiler should be
				selected with special reference to the stresses and disruptive influences which
				each part encounters in service.
4.
				Galvanized pipe may not be used on any boiler or boiler system subject to this
				article, as this may cause deterioration of the boiler.
5. Sweated or soldered copper joints may not

Current through Supplement No. 393, July, 2024
1. Each boiler used
				or proposed to be used within this state, except boilers exempt in North Dakota
				Century Code section 23.1-16-06, must be thoroughly inspected as to their
				construction, installation, condition, and operation as follows:
a. Power boilers must be inspected annually
				both internally while not under pressure and externally while under pressure.
				However, any power boiler or steam generator, the operation of which is an
				integral part of or a necessary adjunct to other continuous processing
				operations, must be inspected internally at such intervals as are permitted by
				the shutting down of the processing operation. The chief boiler inspector may
				provide for extension of time between internal inspections, but an external
				inspection must be made, and report submitted, for purposes of issuing a
				certificate. In all other instances the certificate inspection must be an
				internal inspection when construction permits.
b. Power boilers of one hundred thousand
				pounds [45359.24 kilograms] per hour or more capacity, which comply with
				subsection 2 of North Dakota Century Code section 23.1-16-07, must be inspected
				at least once every thirty-six months internally while not under pressure and
				at least once every twelve months externally while under pressure.
c. Steam traction engines must be inspected
				at least once every twelve months. Inspections must alternate between internal
				inspections, external inspections, and hydrostatic tests.
d. Low-pressure steam boilers must be
				inspected annually. Low-pressure steam boilers of steel construction must be
				inspected alternately internally and externally. The issuance of a certificate
				must normally be based on the internal inspection.
e. Hot water heating and hot water supply
				boilers must be inspected triennially unless they are located in a nursing
				home, school, hospital, nursery school, or kindergarten, in which case they
				must be inspected annually. Internal inspections will be required when deemed
				necessary by the inspector.
f. A
				grace period of two months beyond the period specified in the above
				subdivisions may elapse between inspections.

Current through Supplement No. 393, July, 2024
1. Each discharge
				outlet, except safety valve, safety relief valves, reheater inlet and outlet,
				or superheater inlet connections, must be fitted with a stop valve located at
				an accessible point in the steam-delivery line and as near the boiler nozzle as
				is convenient and practicable. When such outlets are over two inch [50.8
				millimeter] pipe size, the valve or valves used on the connection must be of
				the outside-screw-and-yoke-rising-spindle type so as to indicate from a
				distance by the position of its spindle whether it is closed or open, and the
				wheel may be carried either on the yoke or attached to the spindle. A
				plug-cock-type valve may be used provided the plug is held in place by a guard
				or a gland, the valve is equipped to indicate from a distance whether it is
				closed or open, and the valve is equipped with a slow-opening mechanism. In the
				case of a single boiler and prime mover installation, the stop valve required
				herein may be omitted provided the prime mover throttle valve is equipped with
				an indicator to show whether the valve is open or closed and is designed to
				withstand the required hydrostatic pressure test of the boiler.
2. When the boilers are connected to a common
				header, the connection from each boiler having a manhole opening must be fitted
				with two stop valves having an ample free-blow drain between them. The
				discharge of this drain must be visible to the operator while manipulating the
				valve. The stop valves must consist preferably of one automatic nonreturn valve
				(set next to the boiler) and a second valve of the outside-screw-and-yoke type
				must be used. Where intercommunicating systems of different pressures are
				installed, every boiler on each system must be equipped with an automatic
				nonreturn valve set next to the boiler.
3. When more than one stop valve is required,
				it must have a pressure rating at least equal to that required for the expected
				steam temperature and pressure at the valve, or the pressure rating at least
				equal to eighty-five percent of the lowest set pressure of any safety valve on
				the boiler drum and for the expected temperature of the steam at the valve,
				whichever is greater.
4. All valves
				and fittings on steam lines must have a pressure rating of at least one hundred
				pounds per square inch [689.48 kilopascals] in accordance with the applicable
				American National Standards Institute Standard.

				  or user may appeal to the director who may request a joint inspection by the
				  chief boiler inspector and the deputy inspector or special inspector. Each
				  inspector shall render the inspector's report to the director, and the director
				  shall render the final decision, based upon the data contained in all the
				  inspector's reports.

1. Outlet connections (except for damper
				regulator, feedwater regulator, low-water fuel cutoff, drains, steam gauges, or
				such apparatus that does not permit the escape of an appreciable amount of
				steam or water therefrom) may not be placed on the piping that connects the
				water column to the boiler. The water column must be placed on the piping that
				connects the water column to the boiler. The water column must be provided with
				a valved drain of at least three-quarter inch [19.05 millimeter] pipe size, the
				drain to be piped to a safe location.
2. Each boiler constructed prior to 1999 must
				have three or more gauge cocks located within the visible length of the water
				glass, except when the boiler has two water glasses located on the same
				horizontal lines. Boilers not over thirty-six inches [.914 meters] in diameter,
				in which the heating surface does not exceed one hundred square feet [9.29
				square meters] need have but two gauge cocks.
3. For all installations where the water
				gauge glass or glasses are more than thirty feet [9.14 meters] from the boiler
				operating floor, it is recommended that water level indicating or recording
				gauges be installed at eye height from the operating floor.

Current through Supplement No. 393, July, 2024
1. Each
				steam boiler must have a steam gauge, with dial range not less than one and
				one-half times the pressure at which the safety valve is set, connected to the
				steam space or to the steam connection to the water column. The steam gauge
				must be connected to a siphon or equivalent device of sufficient capacity to
				keep the gauge tube filled with water and so arranged that the gauge cannot be
				shut off from the boiler except by a cock placed near the gauge and provided
				with a tee or lever handle arranged to be parallel to the pipe in which it is
				located when the cock is open.
2.
				When a steam pressure gauge connection longer than eight feet [2.44 meters]
				becomes necessary, a shutoff valve may be used near the boiler provided the
				valve is of the outside-screw-and-yoke type and is locked open. The line must
				be ample size with provision for free blowing. Each boiler must be provided
				with a one-quarter inch [6.35 millimeter] nipple and globe valve connected to
				the steam space for the exclusive purpose of attaching a test gauge when the
				boiler is in service so that the accuracy of the boiler steam gauge may be
				ascertained.
