CHAPTER 402-H.F.No. 2679
An act relating to boilers and engines; modifying
provisions relating to hobby boilers and show engines;
amending Minnesota Statutes 1992, section 183.411,
subdivision 2; repealing Minnesota Statutes 1992,
section 183.411, subdivision 1a.
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MINNESOTA:
Section 1. Minnesota Statutes 1992, section 183.411,
subdivision 2, is amended to read:
Subd. 2. [INSPECTION.] When used only for display and
demonstration purposes, steam farm traction engines, portable
and stationary show engines and portable and stationary show
boilers shall be inspected every two years according to law.
(a) Boilers or show engines of lap seam construction not
certified in Minnesota or previously certified in Minnesota but
that have been repaired or altered after certification, may be
certified in Minnesota if:
(1) all alterations have been done in accordance with
American National Standard ANSI/NB23 R-404 or R-505; or
(2) form R-1, report of alteration, has been prepared by a
registered professional engineer with verification by the
authorized inspection agency responsible for the in-service
inspection of the object in accordance with American National
Standard ANSI/NB23 R-502; or
(3) the engine has received a certificate allowing
operation, or repairs have been authorized under American
National Standard ANSI/NB23 R-404.1, R-404.2, or R-404.3 in
Minnesota or another jurisdiction that accepts the provisions of
American National Standard ANSI/NB23 and an inspection has been
completed by an inspector certified in Minnesota according to
the standards set in paragraph (b).
(b) A hobby boiler or show engine, not certified in
Minnesota or any other jurisdiction must successfully complete,
at the owner's expense, inspection by:
(1) full radiographic examination of the long or
longitudinal seam or ultrasonic examination or dye-penetrant
examination or none of the above, at the discretion of the
boiler inspector, of the long or longitudinal seam of lap-seam
construction; and
(2) ultrasonic examination for metal thickness (for
purposes of calculating the maximum allowable working pressure
the thinnest reading shall be used - see also American National
Standard ANSI/NB23 I-303.8 and a safety factor of six shall be
used in calculating maximum allowable working pressure on all
non-ASME-code hobby and show boilers); and
(3) magnetic particle or radiographic examination of areas
where dye penetrant testing shows possible cracks; and
(4) hydrostatic testing at 1-1/2 maximum allowable working
pressure.
(c) Further each such object shall successfully complete an
inspection of:
(1) the fusible plug;
(2) the safety valve, which must be of American Society of
Mechanical Engineer's approved design and set at the maximum
allowable working pressure and sealed in an appropriate manner
not allowing tampering with the valve setting without destroying
the seal; and
(3) the boiler power piping.
Any longitudinal cracks found in riveted longitudinal seams
requires that the vessel be sealed and not approved for use in
Minnesota. If the boiler or show engine is jacketed, the jacket
must be removed prior to inspection.
Sec. 2. [REPEALER.]
Minnesota Statutes 1992, section 183.411, subdivision 1a,
is repealed.
