  1. Introductions • My name is Randall Austin • I am the Chief Boiler Inspector. • I have been at this position almost 4 years. • Prior to that, 28 years with The State of Colorado, and the Chief Boiler Inspector for the last five years of those 28 years.

  2. History of the,Boiler Safety Section • In 1979, The “Act” is adopted by Arizona, A.R.S. Title 23, Chapter 2, Article 11. Safety Conditions for Boilers and Lined Hot Water Storage Heaters. • 1980 first Arizona Boiler Rules, adopting The National Board Inspection Code, ASME Codes Section I (Power Boilers), II (Materials), IV (Low Pressure Boilers), IX (Welding), ASME CSD-1, ANSI Z21.10.3 (Water Heaters), NFPA 54 (National Fuel and Gas Code). • Boiler Rules revised 4 or 5 times between 1982 and 1998.

  3. History continued…. • 2008-2009 major revision of Arizona Boiler Rules and adoption of additional ASME Codes, effective August 19, 2009. • ASME Code Section VIII, Division 1, 2, and 3 (Pressure Vessels). • ASME B31.1 (Power Piping, piping installed on high pressure steam boilers and high temperature water boilers).

  4. Who is authorized to perform certificate inspections? • State Boiler Inspectors, those employed by the State of Arizona. • Special Boiler Inspectors • Those employed by insurance companies authorized to insure against loss from explosion of boilers or lined hot water storage heaters in this state, and qualified under The National Board, publication NB-369. • Any company operating boilers or lined hot water storage heaters in this state, qualified under The National Board Owner/User program, NB-371.

  5. ASME marks (stamping) New in 2013

  6. What is a boiler? • “Boiler” means a closed vessel in which fluid is heated for use external to itself by the direct application of heat resulting from the combustion of fuel, solid, liquid, or gaseous, or by the use of electricity.

  7. Are there different categories of boilers? • Yes • Low Pressure Heating Boilers; • Steam with an MAWP not greater than 15 psi. • Hot water not greater than 250ºF (MAWT) and/or 160 psi (MAWP). • Power Boilers (high pressure & temperature); • Steam greater than 15 psi (MAWP). • Hot water greater than 250ºF and/or 160 psi. Sometimes →

  8. Boiler continued.. Cast Aluminum Some various types; Firetube, Scotch Marine Wall mounted, watertube

  9. What is a boiler used for? • Hot water heating, low pressure (building heat, indirect potable water) • Hot water supply, low pressure (washing, rinsing, direct potable water) • Steam heating, low pressure (buildings, cooking, farming, saunas) • Steam, high pressure (industrial, buildings, sterilization, dry cleaning, manufacturing) • High temperature, hot water (building heat, industrial applications, high pressure cleaning)

  10. What is a water heater? • “Lined hot water heater” means the same as lined hot water storage heater defined in A.R.S. § 23-471(10) as a vessel which is closed except for openings through which water can flow, that includes the apparatus by which heat is generated and on which all controls and safety devices necessary to prevent pressures greater than 160 psig (1100 kPa gage) and water temperature greater than 210° F are provided, in which potable water is heated by the combustion of fuels, electricity, or any other heat source and removed for external use

  11. Water heaters, Arizona revised statute; • 23-471. Definitions • 10. "Lined hot water storage heater" means a fired lined water heater with linings providing corrosion resistance for supplying potable hot water for commercial purposes. Lined hot water storage heaters are exempted when none of the following limitations are exceeded: • (a) Heat input of two hundred thousand British thermal units per hour. • (b) Water temperature of two hundred ten degrees Fahrenheit. • (c) Nominal water-containing capacity of one hundred twenty gallons.

  12. Water heater continued… • Some types Vertical firetube Copper watertube

  13. Jacketed steam kettles • Arizona Boiler Rules; • R20-5-402. Definitions • 16. “Direct fired jacketed steam kettle” means a pressure vessel with inner and outer walls that is subject to steam pressure and stress, is used to boil or heat liquids or to cook food, and falls under the scope of Section VIII, Division 1, Appendix 19 (Electrically Heated or Gas Fired Jacketed Steam Kettles) of the ASME Boiler and Pressure Vessel Code incorporated by reference in R20-5-404(A).

  14. Jacketed steam kettles continued… • What do they look like? Electric Gas

  15. What is exempt from the Boiler Rules? • R20-5-401. Applicability • This Article applies to all boilers, lined hot water heaters and pressure vessels operated in Arizona, except the following: • 1. Boilers, lined hot water heaters and pressure vessels regulated by the United States Government; • 2. Boilers, lined hot water heaters and pressure vessels operated in private residences or apartment complexes of not more than six units; and • 3. Boilers, lined hot water heaters and pressure vessels operated on Indian reservations. • 4. A lined hot water heater that does not exceed any of the following: • a. Heat input of 200,000 British thermal units per hour; • b. Water temperature of 210° F; and • c. Nominal water containing capacity of 120 gallons.

  16. What requires an Operating Certificate? • All Boilers. • Water Heaters, when it exceeds the following; • (a) Heat input of two hundred thousand British thermal units per hour. • (b) Water temperature of two hundred ten degrees Fahrenheit. • (c) Nominal water-containing capacity of one hundred twenty gallons. • All Direct Fired Jacketed Steam Kettles.

  17. What should i specify when purchasing a new boiler, water heater or kettle? • Boilers • ASME Code construction. • National Board registration, (not applicable for cast iron or cast aluminum). • ASME CSD-1 compliant. • UL834 compliant (electric boilers, resistance type only).

  18. Potable Lined Water Heaters • Water heaters (potable) • ASME Code construction • National Board Registration • ANSI Z21.10.3 compliant • Hot water storage tanks • ASME Code construction • National BoardRegistration

  19. Direct Fired Jacketed Steam Kettles • Steam Kettles • ASME Code construction. • National Board Registration. • ASME Code, Section VIII, Division 1, Appendix 19 compliant.

  20. What requires inspection and when? • Any Boiler, lined water heater and direct fired jacketed steam kettle at time of installation. • High pressure (MAWP < 15 psi) steam boilers require an internal and external every year thereafter where construction permits. • Low pressure (MAWP 15 psi or less) steam boilers biennially (every two years) thereafter. • Direct fired jacketed steam kettles, biennially (every two years) thereafter. • All hydronic (hot water) boilers and water heaters, only require certificate inspection at time of installation.

  21. Any thing else about inspections? • All new power boilers (MAWP < 15 psi steam or high temperature water boilers with an MAWT < 250°F and/or MAWP < 160 psi), require an application be submitted to the Boiler Safety Section before installation or reinstallation. • All used boilers and pressure vessels require an application be submitted to the Boiler Safety Section before installation or reinstallation. • (examples, boilers, water heaters, storage tanks, jacketed steam kettles.) • Reference, Arizona Boiler Rule R20-5-404(C)(10)

  22. Existing installations without an operating certificate. • What if I have a boiler, water heater or direct fired jacketed steam kettle that was installed in the past, but maybe feel the Boiler Safety Section was not notified? • Contact the Boiler Safety Section with the manufacturer’s name, National Board registration number, year built and location so they can perform a search in the database. • Submit an application for certificate inspection provided on our web sight; or • Contact your insurance inspector. • Notify ADOA, Risk Management.

  23. Application for certificate inspection.

  24. Are there fines or penalties for not reporting? • No, we are interested in safety, better late than never. • What if my boiler, water heater or direct fired steam kettle does not meet current Rules, Codes or Standards? • The applicable Rules, Codes and Standards at the time of installation is what’s required for each vessel. • This also applies for National Board registration of vessels that became effective August 19, 2009.

  25. When do I need a National Board “R” Stamp holder to perform repairs? • Anytime welding or brazing is performed on a pressure vessel. • This would include a simple tack weld. • This would include a welded repair to stop a leak or a build up of thinning areas, also known as cladding. • When ever boiler external piping within the scope of ASME Code, Section I, Power Boilers (MAWP < 15 psi steam) whether welded or threaded is replaced. (note; piping includes pipe, fittings and valves)

  26. What about repairs performed in the past without an “R” stamp? • Contact your insurance company boiler inspector to determine the applicability to the National Board Inspection Code. • The Boiler Safety Section will address each situation on a case by case basis, and discuss options with your boiler inspector. • The Boiler Safety Section can provide a list of all National Board “R” stamp holders.

  27. What other pressure vessels should I be concerned about? • Any unfired pressure vessels with an inside diameter exceeding 6 inches. • Any unfired pressure vessels with an MAWP < 15 psi. • Why, you ask? • These vessels are required to be ASME Code constructed as per state and federal law, and repaired in accordance with the National Board Inspection Code.

  28. Who can I contact if I have questions or concerns? • You can call your insurance inspector or; • ADOSH, Boiler Safety Section.

  29. Questions? • Thank you for your time.
