3(1) A boiler shall not be registered under sub-section (4)
of Section 7 of the Act and a certificate shall not be issued
under sub-section (5) of that section with reference to a
boiler, unless the standard conditions in respect of material,
design and construction, which are specified in the subsequent
Chapters of these Regulations, are satisfied in respect of
such a boiler.
(2) Notwithstanding anything contained in sub-regulation (1),
the Chief Inspector may, subject to the provisions of regulation
7 and 8, register a boiler and order the issue of a certificate
authorising the use thereof, under any of the following circumstances,
namely -
| (i) |
when the material used in the construction
of a boiler, steam-pipe, economiser or superheater is
not in conformity with the Indian Boiler Regulations but
is known to be commonly used in other countries as being
suitable for use in the construction of boilers and steam-pipes,
provided that such material is not specifically prohibited
by the Regulation and that the methods of manufacture,
fabrication and heat treatment conform to the specified
Codes or Standards; |
| (ii) |
when the constructional features of a boiler,
steam-pipe, economiser or superheater are not in conformity
with the Regulations but are not considered by the Chief Inspector
to be inferior in strength to those prescribed in the
Regulations and form part of the usual manufacturing practice
of boilers and steam-pipes in other countries; |
| (iii) |
when a boiler, steam-pipe, economiser or
superheater has obviously been built in conformity with
the regulations but no certificate as required under the
regulations is forthcoming. |
(3) No structural part of a boiler, which is subject to pressure,
shall be made of Bessemer process steel or of Cast or Malleable
Cast Iron.
(4) Where no specific provision is made in these regulations
for design or manufacture of any pressure part, the Inspecting
Authority may permit the design, manufacture, stage inspections
and certification of such pressure parts including the valves,
mountings and fittings conforming to the Codes or Standards
like BS, ASME Boiler and pressure vessels code, TEMA, TRD,
GOST and JIS which are known to be commonly used in industrially
advanced countries. The decision of Inspecting Authorities
shall be binding on all Registering authorities.
(4A) The tubes of boilers
and heat
exchangers made
of Titanium
and other exotic metals may be approved as per
international codes, including ASME, BS, DIN, TEMA
with the minimum thickness specified in those codes of
