separate offense.

2.6 EXISTING INSTALLATION: POWER BOILERS

2.6.1 EBO-1 Age Limit of Existing Boilers

A. The age limit of any boiler of nonstandard construction, installed prior to the date

the Act became effective, shall be 30 years except that, a boiler having other

than lap-riveted longitudinal joint, after a thorough internal and external

inspection, and when required by the inspector, a hydrostatic pressure test of 1-

1/2 times the allowable working pressure held for a period of at least 30 minutes

during which no distress or leakage develops, may be continued in operation at

the working pressure determined by § 2.6.3 of this Part.. The age limit of any

nonstandard boiler having lap-riveted longitudinal joints and operating at a

pressure in excess of 50 psi shall be 20 years. This type of boiler, when removed

from an existing setting, shall not be reinstalled for a pressure in excess of 15

psi. A reasonable time for replacement, not to exceed one year, may be given at

the discretion of the Chief Inspector.

B. The age limit of boilers of standard construction installed prior to the date this law

became effective shall be dependent on thorough internal and external

inspection and where required by the inspector, a hydrostatic pressure test not

exceeding 1-1/2 times the allowable working pressure. If the boiler, under these

test conditions, exhibits no distress or leakage, it may be continued in operation

at the working pressure determined by § 2.6.2 of this Part.

C. The shell or drum of a boiler in which a lap seam crack develops along a

longitudinal lap-riveted joint shall be condemned. A lap seam crack is a crack

found in lap seams extending parallel to the longitudinal joint and located either

between or adjacent to rivet holes.

2.6.2 EBO-2 Maximum Allowable Working Pressure for Standard Boiler

The maximum allowable working pressure for standard boilers shall be

determined in accordance with the applicable provisions of the edition of the

ASME Code under which they were constructed and stamped.

2.6.3 EBO-3 Maximum Allowable Working Pressure for Nonstandard Boilers

A. The maximum allowable working pressure for boilers fabricated by riveting shall

be determined by the applicable rules of the 1971 Edition of Section I of the

ASME Code.

B. The lowest factor of safety permissible on existing installations shall be 5.0,

except for horizontal-return- tubular boilers having continuous longitudinal lap

seams more than 12 ft. in length, the factor of safety shall be 8. When this latter

type of boilers is removed from its existing setting, it shall not be reinstalled for

pressures in excess of 15 psi.

C. The maximum allowable working pressure for boilers of welded construction in

service may not exceed that allowable in Section I of the 2017 ASME Code,

incorporated above, for new boilers of the same construction.

D. The maximum allowable working pressure on the shell of a boiler or drum shall

be determined by the strength of the weakest course computed from the

thickness of the plate, the tensile strength of the plate, the efficiency of the

longitudinal joint, the inside diameter of the course, and the factor of safety

allowed by these rules in accordance with the following formula:

1. TStE = maximum allowable working pressure, psi RFS where:

a. TS = specified minimum tensile strength of shell plate material.

When the tensile strength of steel or wrought-iron shell plate is not

known, it shall be taken as 55,000 psi for steel and 45,000 psi for

wrought-iron.

b. t = minimum thickness of shell plate in weakest course, in inches.

c. E = efficiency of longitudinal joint, method of determining which is

given in Paragraph PG-27 of Section I of the ASME Code.

d. R = inside radius of the weakest course of the shell or drum, in

inches.

e. FS = factor of safety which shall be at least 5.0.

E. The inspector may increase the factor of safety, if the condition and safety of the

boiler warrants it.

2.6.4 EBO-4 Cast Iron Headers and Mud Drums

The maximum allowable working pressure on a water tube boiler, the tubes of

which are secured to cast iron or malleable iron headers, or which have cast iron

mud drums, shall not exceed 160 psi.

2.6.5 EBO-5 Pressure on Cast Iron Boilers

The maximum allowable working pressure for any cast iron boiler, except hot

water boilers, shall be 15 psi. See §§ 2.7.1, 2.7.2, and 2.7.4 of this Part.

2.6.6 EBO-6 Safety Valves

A. The use of weighted-lever safety valves or safety valves having either the seat or

disc of cast iron are prohibited; valves of this type of construction shall be

replaced by direct spring loaded, pop-type valves that conform to the

requirements of 2017 ASME Code, Section I.

B. Each boiler shall have at least one ASME/NB Stamped and certified safety valve,

and if it has more than 500 sq. ft. of water-heating surface, or an electric power

input of more than 1100 KW, it shall have two or more safety valves of the same

type.

C. The valve or valves shall be connected to the boiler, independent of any other

steam connection; and attached as close as possible to the boiler, without

unnecessary intervening pipe or fittings. Where alteration is required to conform

to this requirement, owners or users shall be allowed reasonable time in which to

complete the work as permitted by the Chief Inspector.

D. No valves of any description shall be placed between the safety valve and the

boiler nor on the escape pipe, if used. When an escape pipe is used, it shall be at

least the full size of the safety valve discharge and fitted with an open drain to

prevent water lodging in the upper part of the safety valve or in the escape pipe.

When an elbow is placed on a safety valve escape pipe, it shall be located close

to the safety valve outlet or the escape pipe shall be anchored and supported

securely. All safety discharges shall be so located or piped as to be carried clear

from walkways or platforms.

E. The safety valve capacity of each boiler shall be such that the safety valve or

valves will discharge all the steam that can be generated by the boiler without

allowing the pressure to rise more than six percent (6%) above the highest

pressure to which any valve is set, and in no case to more than six percent (6%)

above the maximum allowing working pressure.

F. One or more safety valves on every boiler shall be set at or below the maximum

allowable working pressure. The remaining valves may be set within a range of

three percent (3%) above the maximum allowable working pressure, but the

range of setting of all the safety valves on a boiler shall not exceed ten percent

(10%) of the highest pressure to which any valve is set.

G. When boilers of different maximum allowable working pressures with minimum

safety valve settings varying more than six percent are so connected that steam

can flow toward the lower pressure units, the latter shall be protected by

additional safety valve capacity, if necessary, on the lower pressure side of the

system. The additional safety valve capacity shall be based upon the maximum

amount of steam which can flow into the lower pressure system.

H. In those cases where the boiler is supplied with feed-water directly from water

mains without the use of feeding apparatus (not to include return traps), no safety

valve shall be set at a pressure greater than 94 percent of the lowest pressure

obtained in the supply main feeding the boiler.

I. The relieving capacity of the safety valves on any boiler shall be checked by one

of the three following methods and, if found to be insufficient, additional valves

shall be provided:

1. by making an accumulation test, which consists of shutting off all other

steam discharge outlets from the boiler and forcing the fires to the

maximum. The safety valve capacity shall be sufficient to prevent a rise of

pressure in excess of six percent (6%) of the maximum allowable working

pressure. This method should not be used on a boiler with a super-heater

or re-heater;

2. by measuring the maximum amount of fuel that can be burned and

computing the corresponding evaporative capacity (steam generating

capacity) upon the basis of the heating value of this fuel. These

computations shall be made as outlined in the Appendix of the 2017

ASME Code, Section I;

3. by measuring the maximum amount of feed-water that can be evaporated;

J. When either of the methods outlined in § 2.6.6(I)(2) and (3) of this Part is

employed, the sum of the safety valve capacities shall be equal to or greater than

the maximum evaporative capacity (maximum steam generating capacity) of the

boiler.

2.6.7 EBO-7 Boiler Feeding

A. Each boiler shall have a feed supply which will permit it to be fed at any time

while under pressure.

B. A boiler having more than 500 sq. ft. of water heating surface shall have at least

two suitable means of feeding, at least one of which shall be a feed pump. A

source of feed at a pressure 6 percent greater than the set pressure of the safety

valve with the highest setting may be considered one of the means. Boilers fired

by gaseous, liquid, or solid fuel in suspension may be equipped with a single

means of feeding water provided means are furnished for the shutoff of heat

input prior to the water level reaching the lowest safe level.

C. The feed-water shall be introduced into a boiler in such a manner that the water

will not be discharged directly against surfaces exposed to gases of high

temperature or to direct radiation from the fire. For pressures of 400 psi or over,

the feed-water inlet through the drum shall be fitted with shields, sleeves, or other

suitable means to reduce the effects of temperature differentials in the shell or

head.

D. The feed piping to the boiler shall be provided with a check valve near the boiler

and a valve or cock between the check valve and the boiler. When two or more

boilers are fed from a common source, there shall also be a valve on the branch

to each boiler between the check valve and the source of supply. Whenever a

globe valve is used on feed piping, the inlet shall be under the disc of the valve.

E. In all cases where returns are fed back to the boiler by gravity, there shall be a

check valve and stop valve in each return line, the stop valve to be placed

between the boiler and the check valve, and both shall be located as close to the

boiler as is practicable. It is recommended that no stop valves be placed in the

supply and return pipe connections of a single boiler installation.

F. Where de-aerating heaters are not employed, it is recommended that the

temperature of the feed-water be not less than 120 degrees Fahrenheit to avoid

the possibility of setting up localized stress. Where de-aerating heaters are

employed, it is recommended that the minimum feed-water temperature be not

less than 215 degrees Fahrenheit so that dissolved gases may be thoroughly

released.

2.6.8 EBO-8 Water Level Indicators

A. Each boiler, except forced-flow steam generators with no fixed steam and

waterline, and high-temperature water boilers of the forced circulation type that

have no steam and water-line, shall have at least one water gage glass. Boilers

operated at pressures over 400 psi shall be provided with two water gage

glasses which may be connected to a single water column or connected directly

to the drum.

B. Two independent remote level indicators may be provided instead of one of the

two required gage glasses for boiler drum water level indication in the case of

power boilers with all drum safety valves set at or above 900 psi. When both

remote level indicators are in reliable operation, the remaining gage glass may

be shut off, but shall be maintained in serviceable condition.

C. When the direct reading of gage glass water level is not readily visible to the

operator in his working area, two dependable indirect indications shall be

2.8.1 EPV-1 Maximum Allowable Working Pressure for Standard Pressure

Vessels

The maximum allowable working pressure for standard pressure vessels shall be

determined in accordance with the applicable provisions of the edition of the

ASME Code or the API-ASME Code under which they were constructed and

stamped.

2.8.2 EPV-2 Maximum Allowable Working Pressure for Nonstandard Pressure

Vessels, Except as Provided in § 2.8.3 of this Part.

A. The maximum allowable working pressure of a nonstandard pressure vessel

shall be determined by the strength of the weakest course computed from the

thickness of the plate, the tensile strength of the plate, the efficiency of the

longitudinal joint, the inside diameter of the course and the factor of safety set by

these rules.

1. TStE = maximum allowable working pressure, psi

2. DDDD

3. RFS

4. where:

a. TS = specified minimum tensile strength of shell plate material, psi.

(When the tensile strength of carbon steel plate is not known, it

may be taken as 55,000 psi for temperatures not exceeding 650

degrees Fahrenheit. For other materials use the lowest stress

values for that material from Section VIII.)

b. t = minimum thickness of shell plate of weakest course, inches.

c. E = efficiency of longitudinal joint depending upon construction.

(1) for riveted joints - calculated riveted efficiency; for fusionwelded

and brazed joints - the following percentages apply:

(AA) Single lap weld 40%

(BB) Double lap weld 50%

(CC) Single butt weld 60%

(DD) Double butt weld 70%

(EE) Forge weld 70%

(FF) Brazed steel 80%

d. R = inside radius of weakest course of shell, (inches) provided the

thickness does not exceed 10 percent of the radius. If the thickness

is over 10 percent of the radius, the outer radius shall be used.

e. FS = factor of safety allowed by these rules.

B. The minimum factor of safety in no case be less than 5 for existing installations.

The working pressure shall be decreased when deemed necessary by the

inspector to insure the operation of the vessel within safe limits. The condition of

the vessel and the particular service to which it is subject will be the determining

factors.

C. The maximum allowable working pressure permitted for formed heads under

pressure shall be determined by using the appropriate formulas from 2017 ASME

Code Section VIII, Division 1, and the tensile strength and factors of safety given

in §§ 2.8.1 and 2.8.2 of this Part

D. The maximum allowable working pressure for nonstandard pressure vessels

subjected to external pressure shall be determined by the rules of Section VIII,

Division 1, of the 2017 ASME Code.

2.8.3 EPV-3 Nonstandard Pressure Vessels - Use of Other Formulas

Pressure vessels that were not ASME Code stamped but which were constructed

of known materials and were designed and constructed in accordance with

sound engineering standards, formulas, and practices that provide safety

equivalent to the intent of the Code shall be calculated on the same basis as

used in the original design.

2.8.4 EPV-4 Inspection of Inaccessible Parts

Where, in the opinion of the inspector, as the result of conditions disclosed at the

time of inspection, it may be necessary to remove interior or exterior lining,

covering or brickwork to expose certain parts of the vessel not normally visible,

the owner or user shall remove such material to permit proper inspection and to

determine remaining thickness.

2.8.5 EPV-5 Overpressure Protection

Each pressure vessel shall be provided with pressure relief devices indicating

and controlling devices as necessary to protect against overpressure. These

devices shall be so constructed, located and installed that they cannot readily be

rendered inoperative. The relieving capacity of such pressure relief device shall

be adequate to prevent a rise in pressure in the vessel of more than 10 percent

or 3 psi, whichever is greater, above the maximum allowable working pressure

except when multiple relieving devices are provided, they shall prevent the

pressure from rising more than 16 percent or 4 psi, whichever is greater above

the maximum allowable working pressure. When multiple pressure relieving

devices are provided, at least one device shall be set at or below the maximum

allowable working pressure and the additional devices shall be set no higher than

105% of the maximum allowable working pressure. Where an additional hazard

is involved due to fire or other unexpected sources of external heat, the pressure

relief devices shall meet the requirements of ASME Code Section VIII, Division,

paragraph UG-125 or Division 2, paragraph AR-130, whichever is applicable.

2.8.6 EPV-6 Repairs and Renewals of Fittings and Appliances

Whenever repairs are made to fittings and appurtenances or it becomes

necessary to replace them, the work must comply with the requirements for new

installations.
