(430 ILCS 75/4) (from Ch. 111 1/2, par. 3205)
Sec. 4. Existing
boilers and pressure vessels.
(a) The maximum allowable pressure consistent with the maximum and
minimum operating temperatures of a boiler carrying the ASME
Code symbol or of a pressure vessel carrying the ASME Code
symbol shall be determined by the applicable section of the Code under
which it was constructed and stamped or a later edition
of the ASME Code, provided the
rating conforms with the
rules of the later edition.
(b) The maximum allowable pressure consistent with the maximum and
minimum operating temperatures of a boiler or pressure vessel
that does not carry the ASME Code symbol shall be
computed in accordance with the rules and regulations of the
Board, unless the boiler
or pressure vessel is of special design or
construction, in which case the Board may grant, at its discretion, a special
operating permit consistent with the safety objectives of the rules and
regulations of the Board.
(c) This Act does not prohibit the use,
sale, or reinstallation of
a boiler or pressure vessel
referred to in this Section, provided it has
been made to conform to the rules and regulations of the Board
governing existing installations, and provided, further, it has not been
found upon inspection to be in an unsafe condition.
