Supervision Administration Regulation (TSG G3001).
4.2 Prior to construction, the installation and construction organizations may carry
out construction only after informing the special equipment safety supervision
department of the boiler equipment installation condition.
4.3 The boiler installation work shall meet those specified in Boiler Safety Technical
Supervision Administration Regulation (TSG G0001), and the installation process shall
be subjected to the supervision and inspection of national special equipment safety
supervision and inspection organization; the boiler failing to pass the supervision and
inspection shall not be put into service.
4.4 Qualifications of operating personnel for welding or non-destructive testing shall
meet those specified in GB/T 16508.1.
4.5 During the installation of boiler, in case of quality problems (pressure component
influences safe application), the installation shall be stopped.
4.6 After the completion of boiler installation, the installation organization shall hand
over the relevant technical data to the using organization within 30 days after
acceptance.
4.7 Boiler using organization shall establish safety technical file of boiler equipment.
5 Foundation Inspection and Marking Out
5.1 Before boiler and its auxiliary equipment are put in place, the foundation
dimension and position shall be inspected, and the permissible deviation shall meet
those specified in boiler equipment technical document; if there is no requirement, the
permissible deviation shall meet those specified in GB 50273.
5.2 Before shell boiler installation, vertical and transversal installation reference lines
as well as elevation reference point shall be marked.
6 Steel Frame Installation
6.1 Before steel frame installation, the quantity of members shall be checked against
construction drawing and such primary members as upright column, girder, etc. shall
be inspected, and the permissible deviation shall meet those specified in boiler
equipment technical document; if there is no requirement, it shall meet those specified
in GB 50273.
in GB/T 16508.4.
7.1.2 Before installing the support and suspension device of shell and header, the
following contents shall be inspected:
a) The arcs of the contact parts shall be fit and meet the requirements of design
document;
b) The contact between support and steel beam shall be in good condition;
c) Suspension device shall be firm, and the installation of spring suspension
device shall meet the requirements of design document.
7.2 Installation requirements
7.2.1 After the steel frame is installed and fixed, the shell may be hoisted and put in
place; as for shell not directly supported by steel beam, firm temporary support shall
be installed, and the temporary support shall be removed before feeding water for
boiler hydrostatic test.
7.2.2 As for putting shell and header in place, expansion clearance of support shall
be reserved in their expansion direction, and they shall be temporarily fixed.
7.2.3 As for the installation of devices in the shell, the following contents shall be
inspected:
a) The quantity of parts shall not be short;
b) The connection of steam or water supply connection clapboard shall meet the
requirements of design document;
c) The flange joint surface shall be tight;
d) Connection of the connecting pieces shall be firm and the looseness preventing
device shall be arranged.
7.3 Installation acceptance requirements
After the installation of shell and header is completed, the center lines of shell and
header shall be measured according to vertical and transversal installation reference
lines as well as elevation reference line, and the permissible deviation shall meet those
specified in boiler equipment technical document; if there is no requirement, the
permissible deviation shall meet those specified in GB 50273.
b) The non-destructive testing shall meet those specified in GB/T 16508.4;
c) In case the result of non-destructive testing is unqualified, the unqualified welds
shall be repaired, and re-inspection shall be carried out for the welded joints of
the same kind welded by the corresponding welder with double quantity of the
unqualified welds; in case there is still unqualified weld in re-inspection, flaw
inspection shall be carried out for all the welded joints of the same kind welded
by the corresponding welder;
d) In case undesirable defect is found in welded joints through radiographic
inspection, the reason shall be found out, feasible repair scheme shall be made
and then the welded joint may be repaired; the number of times for repairing on
the same part shall not exceed 2, otherwise, the repair shall be approved by
