Universal Citation: HI Admin Rules 12-222.1-2

Current through August, 2024

(a) The following shall apply to all power boilers:

(1) All power boilers in operation in this jurisdiction shall have a valid and current operating permit issued for a specific location by the department;

(2) Changes in location or ownership shall require notification of the department and may require re-inspection;

(3) Power boilers shall bear the ASME BPVC symbol stamp 'S", "E", "M", or ASME certification mark with 'S", "E", or "M" designator and the National Board registration number;

(4) ASME and NB stamping shall be legible and not be concealed by insulation or paint; and

(5) Upon completion of the installation of a new power boiler, each power boiler shall be marked by an inspector employed by the department with a state serial number, consisting of letters and figures to be not less than five sixteenths (5/16) of an inch in height and arranged as HAW# # # #-Year.

(b) The age limit of boilers of standard construction installed prior to the date these rules become effective shall be dependent on thorough internal and external inspection, and where required by the inspector, a pressure test not exceeding one and one-half times (1.5) the maximum 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 the applicable provisions of the edition of the ASME BPVC under which they were constructed and stamped.

(c) The age limit of any boiler of nonstandard construction without a lap-riveted longitudinal joint, installed prior to the date these rules become effective, shall be thirty (30) years, unless the department determines it may continue in operation at a pressure determined by the department as long as the following apply:

(1) The boiler passes a thorough internal and external inspection; and

(2) If required by an inspector, it passes a pressure test not exceeding one and one-half (1.5) times the maximum allowable working pressure, held for a period of at least thirty (30) minutes during which no distress or leakage develops.

(d) The age limit of any existing nonstandard boiler having lap-riveted longitudinal joints and operated at a pressure in excess of fifty (50) psig shall be twenty (20) years. This type of boiler, when removed from an existing setting, shall not be reinstalled and used at a pressure in excess of fifteen (15) psig. A reasonable time for replacement, not to exceed one (1) year, may be given at the discretion of the department. Lap seam riveted boilers are not allowed in this jurisdiction.

(e) Power boilers designed and stamped in accordance with ASME BPVC Section I, if trimmed for use as low pressure steam boilers, shall be inspected internally and externally on a power boiler frequency, if any of the following is exceeded:

(1) Heating surface greater than 100 square feet;

(2) Heat input greater than 400,000 Btu/hr; or

(3) Power boilers with manways.

(f) The following shall be considered new boiler installations:

(1) Replacement of an existing power boiler;

(2) Replacement of boilers at an existing location with a used or second-hand boiler; and

(3) Used or second-hand power boilers when installed in this jurisdiction, shall be equipped with fittings and appurtenances that comply with new installations.

(g) Replacement or repairs to boiler fittings, appurtenances or appliances, controls, and safety devices, shall comply with the applicable ASME BPVC and National Board Inspection Codes.

(h) Weld repairs, alterations, and inspection records shall be submitted with the installation application.

(i) All boiler piping shall be designed and installed in accordance with ASME BPVC Section I and ASME B31.1 for used or second-hand boilers. The use of galvanized piping is prohibited for power boiler pressure piping.
