Section 408.4172. Nonstandard boilers; bringing into state.

(1) If a nonstandard boiler that is in use in this state is removed outside the boundaries of the state, it cannot be brought into the state and reinstalled without the permission of the board of boiler rules.

(2)     A person may petition the board to approve the use of a nonstandard boiler. Upon receipt of the petition, the board shall cause to be conducted testing and evaluation it considers desirable for the nonstandard boiler to determine whether construction is equivalent to standards specified in R 408.4025.

(3)     A boiler owner requesting to have a special installation and operational permit shall submit the following items to the board of boiler rules, as applicable, in the English language and units:

(a)     A list of all existing or proposed design and service conditions, maximum allowable working pressure (MAWP), and temperature, internal and external loading, corrosion and erosion allowance, heat treatment, service requirements, or service conditions.

(b)     Documentation that the manufacture of the boiler is based on requirements from the applicable ASME code section as follows:

(i)     Power boilers – section I

(ii)     Materials specifications – section II

(iii)     Nuclear power plant components – section III, division 1 and 2

(iv)     Heating boilers – section IV

(v)     Pressure vessels – section VIII, division 1 and 2

(vi)     Welding and brazing qualifications – section IX

(vii)     Fiberglass-reinforced plastic pressure vessels – section X

(viii)     Power piping – ASME B31.1

(4)      If the design, construction, and certification were not based on ASME code rules, the manufacturer of the boiler shall provide a copy of the design rules used and show how they meet or exceed the ASME code requirements by providing all of the following:

(a)        A complete set of design drawings showing weld joint details and construction including internal and external attachments.

(b)        A list of all pressure boundary materials or those materials and the material’s thickness subject to stress due to pressure and loading. The list shall include a material specification to meet or exceed the applicable ASME codes specification. If material used is a specification other than referenced in the applicable ASME code section, the manufacturer of the boiler through the owner shall submit a copy of the material specifications used in the vessel construction and indicate how it is considered equivalent to the ASME Code.  Stress values used in all design calculations shall meet or exceed the

maximum allowable stress values permitted for materials in the applicable ASME code section.

(c)     Documentation of any mill identification, including location of identification.

(d)     Manufacturers’ materials test reports and traceability including test reports required by applicable code section.

(e)        Welding or brazing procedure specifications and welder or brazer performance qualification records.

(f)    NDE procedures and results of examinations.

(g)     Record of pressure test or proof test.

(h)       Documentation showing the quality assurance program used by manufacturer is equivalent to requirements of the ASME code.

(i)          Identification  of  the  inspection   agency  performing   inspections  and  certifying manufacturer’s data report or equivalent.

(j)     Evidence of qualification or certification of the inspection agency by a jurisdictional authority.

(k)      Documentation to show that inspectors making certification inspections have been certified as required by the jurisdictional authority. Individual names and commission numbers (if any) shall be provided. System of supervisory control of inspection shall be included.

(l)          Documentation  of  fabrication  inspections  by  the  manufacturer   and  inspection agency.

(m)     An internal and external inspection report by inspection agency inspectors.

(n)     A facsimile of the nameplate or stamping.

(o)        A copy of manufacturer’s data report or equivalent document certified by the manufacturer and the inspection agency’s inspector.

(p)     A copy of any code or standard used for design or construction.

(5)      The original code of construction shall be used to establish the allowable stresses and joint efficiencies when calculating the MAWP of a vessel.
