Aluminium Welded Vessels
1 Scope
This standard specifies the requirements for the design, manufacturing, inspection and acceptance
of aluminium welded vessels (including vessels with such components as enclosure made of aluminium
or line with aluminium).
1.1 This standard is applicable to the atmospheric pressure vessels and the pressure vessels with
design pressure no larger than 8MPa.
1.2 The design temperature range applicable to this standard shall be determined according to the
allowable service temperature of aluminium products.
1.3 This standard is not applicable to the following various vessels .
a) Directly-fired vessels;
b) Vessels in the nuclear-energy plant;
c) Compression vessel chambers as the component parts of such motive mechanical equipments
with rotation or back and forward motion (such as centrifugal pump shell, cylinder body of reciprocating
pump, cylinder body of compressor, cylinder body of refrigerating machine, case of blower, wobbling
drum of centrifuge, etc .);
d) Frequently-transpo11ed vessels;
e) Vessels with internal diameter be less than l 50mm (means width, height or diagonal line for
the noncircular section, such as the diagonal line of rectangular or the major axis of ellipse);
f) Vessels requiring fatigue analysis.
1.4 For the compression components with structural dimension not being determined by this
standard, the following methods may be adopted in the design of these compression components, but
they shall be evaluated and approved by the National Technical Committee on Pressure Vessels of
Standardization Administration of China.
- - Stress analysis , including finite element method;
--Replication experiment analys is (such as experimental stress analysis and replication
hydrau I ic pressure test);
--Comparison empirical design by sing such comparable structures that have been in service.
