Current through Reg. 50, No. 138; July 16, 2024
(1) Repairs to all boilers and appurtenances
				thereof that come under this rule chapter must conform to the National Board
				Inspection Code, which is incorporated by reference in Rule
				 69A-51.010, F.A.C. Where a
				repair affecting the safety of the boiler is necessary, the owner and/or user
				shall call an authorized inspector for consultation and advice as to the best
				method of making the repair, and the completed work is subject to the
				authorized inspector's approval.
(2) No company may undertake a repair to a
				boiler unless the contemplated repairs have first been approved by an
				authorized inspector.
(3) Should a
				repair outside the scope of this rule chapter be deemed feasible by an
				authorized inspector, such a repair may be undertaken only with the full
				knowledge and consent of the chief boiler inspector the Boiler Safety
				Program.
(4) This rule applies to
				repairs or alterations to boilers which come under this rule chapter. The
				repairs made in accordance with this rule chapter shall result in a boiler that
				is as safe to operate as when it was new.
(5) Upon completion of repairs of an unsafe
				condition, the authorized inspection agency responsible for the issuance of the
				withheld certificate of operation shall submit a reinspection report to the
				chief boiler inspector. The reinspection report shall include pertinent data
				pertaining to the required repairs including a copy of the National Board of
				Boiler and Pressure Vessel Inspectors' Form R-1, Report of Repair (Rev.
				01/28/19), if applicable, which is hereby incorporated by reference and is
				available at the following link:

.
(6) Lap seam crack. The shell or drum of a
				boiler in which a lap seam crack is discovered along a longitudinal riveted
				joint must be immediately removed from service. If the boiler is not more than
				15 years old, a complete new course of the original thickness may be installed
				at the discretion of the authorized inspector (with the approval of the chief
				boiler inspector). Patching is prohibited.
(7) Hydrostatic pressure test.
(a) A hydrostatic pressure test, when applied
				to boilers of riveted or welded construction, must not exceed one and one-half
				(1 1/2) times the maximum allowable working pressure. Hydrostatic pressure
				applied to glass lined vessels must not exceed the maximum allowable working
				pressure. During the hydrostatic pressure test, the safety valve or valves must
				be removed or each valve disk must be held down by means of a testing clamp and
				not by applying additional load to the spring with the compression screw. The
				minimum temperature of the water used to apply a hydrostatic test must be not
				less than 60º F., and the maximum temperature must not exceed 120º
				F.
(b) When a hydrostatic test is
				to be applied to existing installations, the pressure must be as follows:
1. For all cases involving the question of
				tightness, the pressure must be equal to the release or set pressure of the
				safety valve or valves having the lowest release setting.
2. For all cases involving the question of
				safety, the pressure must be equal to one and one-half (1 1/2) times, the
				maximum allowable working pressure.
