Current through Register Vol. 51, No. 1, July 1, 2024
RELATES TO: KRS Chapter 236
NECESSITY, FUNCTION, AND CONFORMITY:
				KRS
				236.030 requires the commissioner to
				promulgate administrative regulations that establish standards for the safe
				construction, installation, inspection, and repair of boilers, pressure
				vessels, and associated pressure piping.
				KRS
				236.040 requires all boiler and pressure
				vessels to conform to the rules and regulations formulated by the commissioner
				and establishes the standards for pressure piping and pressure vessels for
				human occupancy.
				KRS
				236.110 establishes the inspection
				requirements for boilers, pressure vessels, and pressure piping. This
				administrative regulation establishes the design, construction, and inspection
				requirements of the boiler inspection section for all boilers and pressure
				vessels not exempted by
				KRS
				236.060.
Section
			 1. Minimum Standards.
(1) Boilers
			 and pressure vessels. All new boilers and new pressure vessels shall comply
			 with applicable provisions of 815 KAR Chapter 15 and the ASME Boiler and
			 Pressure Vessel Code, 2013 Edition or subsequent editions, as established by
			 KRS
			 236.040(2), except new
			 boilers and new pressure vessels approved as state specials pursuant to Section
			 4 of this administrative regulation. All pressure vessels for human occupancy
			 shall comply with the ASME Safety Standard for Pressure Vessels for Human
			 Occupancy, 2012 Edition or subsequent editions, as established by
			 KRS
			 236.040(3).
(2) ASME stamps. New boilers and new pressure
			 vessels shall be stamped with the applicable certification mark of the ASME
			 Boiler and Pressure Vessel Code.
(3) Installation standard. Installation of
			 all boilers and pressure vessels shall conform to the National Board Inspection
			 Code Part 1, 2015 edition or subsequent editions.
(4) Pressure piping.
(a) All new pressure piping installations
			 connected to the boiler or pressure vessel shall conform to the National Board
			 Inspection Code Part 1, 2015 edition, and the applicable standards referenced
			 in this subsection, as established by
			 KRS
			 236.040(2):
1. ASME Code for Power Piping, B31.1, 2012
			 edition or subsequent editions;
2.
			 ASME Code for Process Piping, B31.3, 2012 edition or subsequent
			 editions;
3. ASME Code for
			 Refrigeration Piping and Heat Transfer Components, B31.5, 2013 edition or
			 subsequent editions;
4. ASME Code
			 for Building Services Piping, B31.9, 2011 edition or subsequent editions;
			 and
5. ASME Code for Hydrogen
			 Piping and Pipelines, B31.12, 2014 edition or subsequent editions.
(b) The maximum allowable design
			 temperature and pressure of the piping system and all of its component parts
			 shall meet or exceed the operating control settings of the boiler or pressure
			 vessel.
(c) If the maximum
			 allowable design temperature or pressure of the boiler exceeds the maximum
			 design limits of the piping system or any of its component parts, the pipe and
			 its components shall not be used unless the following conditions are met:
1. The temperature and pressure controls on
			 the boiler are permanently set to prevent operation in excess of the design
			 limits of the piping system; and
2.
			 Safety valve or valves shall be installed on the boiler, pressure vessel, or
			 the piping system to protect the system from excess pressure or
			 temperature.
(5) Welded piping joints. Welded joints in
			 pressure piping shall be installed by qualified welders in accordance with the
			 ASME Code, Section IX, as required by the standards referenced in subsection
			 (4) of this section.
