(M) The maximum allowable steam working pressure for cast iron boilers, except for hot water boilers, is to be fifteen psig.

(N) The maximum allowable working pressure on the shell or drum of an existing nonstandard boiler is to be determined by the strength of the weakest section of the structure, computed from the thickness of the plate, the tensile strength of the plate, the efficiency of the longitudinal joint or the tube ligaments, the inside diameter of the weakest course and the factor of safety allowed by these rules.

(S)(t)(E)/(R)(F) = Maximum allowable working pressure, psig.

Where:

S = ultimate tensile strength of shell plates, psi.

When the ultimate tensile strength, "S", of steel or wrought-iron shell plates is not known, it is to be taken as fifty-five thousand psi for steel and forty-five thousand psi for wrought-iron.

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

E = efficiency of longitudinal joint.

For riveted construction, "E" is to be determined by rules given in paragraph "PR-15" of the 1971 edition of the "ASME Boiler and Pressure Vessel Code, section I."

For tube ligaments, "E" is to be determined by rules "PG-52" or, "PG-53" of the "ASME Boiler and Pressure Vessel Code, section I" and "PR-25", of the 1971 edition of the "ASME Boiler and Pressure Vessel Code, section I."

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

F = factor of safety permitted.

(1) When computing the ultimate strength of rivets in shear, the following values in pounds per square inch of the cross-sectional area of the rivet shank (after driving) is to be used:

Strength of existing rivets in shear

(2) When the diameter of the rivet holes in the longitudinal joints of a boiler is not known, the diameter and cross sectional area of rivets, after driving, may be ascertained from the following table or by cutting out one rivet in the body of the joint:

Sizes of rivets in inches based on plate thickness

(3) The resistance of steel to crushing is to be taken as ninety-five thousand psi.

(4) The lowest factor of safety permissible on existing installations is to be 4.5 excepting for horizontal return tubular boilers having continuous longitudinal lap seams more than twelve feet in length where the factor of safety is to be 8, and when this latter type of boiler is removed from its existing setting, it is not to be reinstalled for pressure in excess of fifteen psig. Reinstalled or secondhand nonstandard boilers are to have a minimum factor of safety of 6 when the longitudinal seams are of lap riveted construction, and a minimum factor of 5 when the longitudinal seams are of butt and double strap construction. A boiler constructed of wrought iron is to have a factor of safety of 7. Upon inspection of the boiler, if conditions are found which justify a reduction of the safe working pressure, the factor of safety as stated above is to be appropriately increased.

(O) The maximum allowable working pressure of a nonstandard low pressure steam boiler is not to exceed fifteen psig.

(P) The maximum allowable working pressure of a nonstandard boiler constructed principally of cast iron or constructed of a cast iron shell or heads and steel tubes is not to exceed thirty psig for hot water service.

(Q) The maximum allowable working pressure of a nonstandard water tube boiler, the tubes of which are secured to cast iron or malleable iron headers, or which have cast iron mud drums, is not to exceed one hundred sixty psig for steam service.

(R) If in the judgment of the inspector a low pressure boiler is unsafe for operation at the pressure previously approved, the pressure is to be reduced, proper repair made, or the boiler retired from service.

(S) Nonstandard pressure vessels except those exempt in section 4104.04 of the Revised Code and paragraph "U-1" of the "ASME Boiler and Pressure Vessel Code, section VIII", are prohibited for use in excess of fifteen psi internal or external pressure.

(T) Any owner or operator who in any manner loads the safety valve or valves to a greater pressure than that allowed by the certificate of operation is subject to the penalty provided in section 4104.99 of the Revised Code.

(M) The maximum allowable steam working pressure for cast iron boilers, except for hot water boilers, is to be fifteen psig.

(N) The maximum allowable working pressure on the shell or drum of an existing nonstandard boiler is to be determined by the strength of the weakest section of the structure, computed from the thickness of the plate, the tensile strength of the plate, the efficiency of the longitudinal joint or the tube ligaments, the inside diameter of the weakest course and the factor of safety allowed by these rules.

(S)(t)(E)/(R)(F) = Maximum allowable working pressure, psig.

Where:

S = ultimate tensile strength of shell plates, psi.

When the ultimate tensile strength, "S", of steel or wrought-iron shell plates is not known, it is to be taken as fifty-five thousand psi for steel and forty-five thousand psi for wrought-iron.

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

E = efficiency of longitudinal joint.

For riveted construction, "E" is to be determined by rules given in paragraph "PR-15" of the 1971 edition of the "ASME Boiler and Pressure Vessel Code, section I."

For tube ligaments, "E" is to be determined by rules "PG-52" or, "PG-53" of the "ASME Boiler and Pressure Vessel Code, section I" and "PR-25", of the 1971 edition of the "ASME Boiler and Pressure Vessel Code, section I."

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

F = factor of safety permitted.

(1) When computing the ultimate strength of rivets in shear, the following values in pounds per square inch of the cross-sectional area of the rivet shank (after driving) is to be used:

Strength of existing rivets in shear

(2) When the diameter of the rivet holes in the longitudinal joints of a boiler is not known, the diameter and cross sectional area of rivets, after driving, may be ascertained from the following table or by cutting out one rivet in the body of the joint:

Sizes of rivets in inches based on plate thickness

(3) The resistance of steel to crushing is to be taken as ninety-five thousand psi.

(4) The lowest factor of safety permissible on existing installations is to be 4.5 excepting for horizontal return tubular boilers having continuous longitudinal lap seams more than twelve feet in length where the factor of safety is to be 8, and when this latter type of boiler is removed from its existing setting, it is not to be reinstalled for pressure in excess of fifteen psig. Reinstalled or secondhand nonstandard boilers are to have a minimum factor of safety of 6 when the longitudinal seams are of lap riveted construction, and a minimum factor of 5 when the longitudinal seams are of butt and double strap construction. A boiler constructed of wrought iron is to have a factor of safety of 7. Upon inspection of the boiler, if conditions are found which justify a reduction of the safe working pressure, the factor of safety as stated above is to be appropriately increased.

(O) The maximum allowable working pressure of a nonstandard low pressure steam boiler is not to exceed fifteen psig.

(P) The maximum allowable working pressure of a nonstandard boiler constructed principally of cast iron or constructed of a cast iron shell or heads and steel tubes is not to exceed thirty psig for hot water service.

(Q) The maximum allowable working pressure of a nonstandard water tube boiler, the tubes of which are secured to cast iron or malleable iron headers, or which have cast iron mud drums, is not to exceed one hundred sixty psig for steam service.

(R) If in the judgment of the inspector a low pressure boiler is unsafe for operation at the pressure previously approved, the pressure is to be reduced, proper repair made, or the boiler retired from service.

(S) Nonstandard pressure vessels except those exempt in section 4104.04 of the Revised Code and paragraph "U-1" of the "ASME Boiler and Pressure Vessel Code, section VIII", are prohibited for use in excess of fifteen psi internal or external pressure.

(T) Any owner or operator who in any manner loads the safety valve or valves to a greater pressure than that allowed by the certificate of operation is subject to the penalty provided in section 4104.99 of the Revised Code.
