1999 SESSION
Be it enacted by the General Assembly of Virginia:
1. That § 40.1-51.8 of the Code of Virginia is amended and reenacted and that the Code of Virginia is amended by adding in Chapter 3.1 of Title 40.1 an article numbered 2, consisting of sections numbered 40.1-51.19:1 through 40.1-51.19:5, as follows:
§ 40.1-51.8. Exemptions.
The provisions of this chapter article shall not apply to any of the following:
1. Boilers or unfired pressure vessels owned or operated by the federal government or any agency thereof;
2. Boilers or fired or unfired pressure vessels used in private residences or apartment houses of less than four apartments;
3. Boilers of railroad companies maintained on railborne vehicles or those used to propel waterborne vessels;
4. Antique or model boilers as defined in § 40.1-51.19:1;
4. 5. Hot water supply boilers, water heaters, and unfired pressure vessels
used as hot water supply storage tanks heated by steam or any other indirect means when the following
limitations are not exceeded:
a. A heat input of 200,000 British thermal units per hour;
b. A water temperature of 210° Fahrenheit;
c. A water-containing capacity of 120 gallons.;
5. 6. Unfired pressure vessels containing air only which are located on
vehicles or vessels designed and used primarily for transporting passengers or freight;
6. 7. Unfired pressure vessels containing air only, installed on the
right-of-way of railroads and used directly in the operation of trains;
7. 8. Unfired pressure vessels used for containing water under pressure when
either of the following are not exceeded:
a. A design pressure of 300 psi; or
b. A design temperature of 210° Fahrenheit.;
8. 9. Unfired pressure vessels containing water in combination with air
pressure, the compression of which serves only as a cushion, that do not exceed:
a. A design pressure of 300 psi;
b. A design temperature of 210° Fahrenheit; or
c. A water-containing capacity of 120 gallons.;
9. 10. Unfired pressure vessels containing air only, providing the volume does
not exceed eight cubic feet nor the operating pressure is not greater than 175 pounds;
10. 11. Unfired pressure vessels having an operating pressure not exceeding
fifteen pounds with no limitation on size;
11. 12. Pressure vessels that do not exceed:
a. Five cubic feet in volume and 250 pounds per square inch gauge pressure;
b. One and one-half cubic feet in volume and 600 pounds per square inch gauge pressure; and
c. An inside diameter of six inches with no limitations on gauge pressure.;
12. 13. Pressure vessels used for transportation or storage of compressed gases
when constructed in compliance with the specifications of the United States Department of
Transportation and when charged with gas marked, maintained, and periodically
requalified for use, as required by appropriate regulations of the United
States Department of Transportation; all others shall be used in accordance
with Chapter 7 (§ 27-86 et seq.) of Title 27;
13. 14. Unfired pressure vessels used in and as a part of electric substations
owned or operated by an electric utility, provided such electric substation is enclosed, locked, and
inaccessible to the public; or
14. 15. Coil type hot water boilers without any steam space where water flashes
into steam when released through a manually operated nozzle, unless steam is
generated within the coil or unless one of the following limitations is
exceeded:
a. Three-fourths inch diameter tubing or pipe size with no drums or headers attached;
b. Nominal water containing capacity not exceeding six gallons; and
c. Water temperature not exceeding 350° Fahrenheit.
§ 40.1-51.19:1. Definitions.
As used in this article:
“Antique boiler” means any boiler used solely for demonstration, exhibition, ceremonial or educational purposes, including but not limited to, historical artifacts such as portable and stationary show boilers, farm traction engines and locomotives.
“Model boiler” means any boiler fabricated to demonstrate an original design or to reproduce or replicate a historic artifact, and used primarily for demonstration, exhibition or educational purposes.
§ 40.1-51.19:2. Applicability.
Antique and model boilers may continue in operation but shall be in compliance with the provisions of this article by July 1, 2000.
§ 40.1-51.19:3. Inspection and testing.
A. An antique or model boiler shall be inspected every two years. It shall be the duty of the owner of any antique or model boiler to obtain and display an inspection certificate.
B. The inspection of every antique or model boiler shall include an examination of or for the following:
1. The fusible plug.
2. The safety valve or valves. Such valve or valves shall be (i) rated by the American Society of Mechanical Engineers (ASME), (ii) set at or below the maximum allowable working pressure, and (iii) sealed in a manner that does not allow tampering with the valve without destroying the seal.
3. Internal corrosion.
4. Leakage.
5. The boiler power piping, up to and including the first valve.
C. An antique or model boiler shall be subjected to nondestructive testing, at the owner’s expense, to determine the maximum allowable working pressure in accordance with Boiler and Pressure Vessel rules and regulations (16 VAC 25-50-10 et seq.).
D. All antique and model boilers shall pass a hydrostatic test at one and one-half maximum allowable working pressure, conducted in the presence of an inspector, at the time of certification and as frequently as deemed necessary based on inspections or other evidence. An antique or model boiler that does not meet the requirements of the ASME code and is not certified in the Commonwealth, shall, at the owner’s expense, be tested to twice the maximum allowable working pressure and, to be operated, shall have a successful (i) complete radiographic or ultrasonic examination of the long or longitudinal seam; (ii) ultrasonic examination for metal thickness, and for the purpose of calculating the maximum allowable working pressure, the thinnest reading shall be used; and (iii) dye penetrant examination for cracks with a magnetic particle, ultrasonic, or radiographic examination of areas where dye penetrant testing shows possible cracks.
The requirements of this subsection for full radiographic or ultrasonic examination may be waived after the initial inspection if the inspector finds that the general standards of subsection B are met and the safety valve or valves are set at the maximum allowable working pressure determined by calculations from the ultrasonic results, or 100 pounds per square inch, whichever is lower.
§ 40.1-51.19:4. Operations and maintenance.
A. An antique or model boiler must be attended by a person reasonably competent to operate such boiler when in operation. For the purposes of this section, an antique or model boiler may be considered as not being in operation when all of the following conditions exist:
1. The water level is at least one-third of the water gauge glass;
2. The header or dome valve is in a closed position;
3. The fire is banked and the draft doors closed or the fire is extinguished;
4. The boiler pressure is at least twenty pounds per square inch below the lowest safety valve set pressure.
B. All welding performed on antique or model boilers shall be done by an “R” stamp holder in accordance with the inspection code of the National Board of Boiler and Pressure Vessel Inspectors.
C. Repairs to longitudinal riveted joints are prohibited.
§ 40.1-51.19:5. Civil penalty.
A. It shall be unlawful for any person, firm, partnership or corporation to operate in the Commonwealth an antique or model boiler without a valid certificate. Any such person shall be subject to a civil penalty as provided by § 40.1-51.12.
B. Any owner or user who leaves or causes to leave an antique or model boiler unattended while in operation shall be in violation of this article and subject to a civil penalty not to exceed $100. Any owner or user who leaves or causes to leave an antique or model boiler unattended while in operation at an event to which members of the general public are invited shall be in violation of this article and subject to a civil penalty not to exceed $5,000. Each instance of such violation shall be deemed a separate offense.
2. That the provisions of this act shall become effective on July 1, 2000.
