1.1 Subject content
This standard is related to steel pressure vessels based on design by analysis. Design methods are provided based on elastic stress analysis, plastic failure criteria and elastic-plastic failure criteria. More strict requirements are specified for manufacture, inspection and acceptance than GB 150 "Steel Pressure Vessels".
This standard shall be implemented with GB 150 simultaneously. Any one of them can be applied, if their own requirements are met.
1.2 Scope
PREFIX = ST11.2.1This standard is applicable to:
a) Vessels whose design pressures are greater than or equal to 0.1 MPa and less than 100 MPa;
b) Vessels whose vacuum degrees are higher than or equal to 0.02 MPa.
1.2.2The applicable design temperature of this standard shall be lower than the corresponding temperature by which the steel creep controlling its admissible stress intensity.
1.2.3This standard is not applicable to the following various vessels:
a) Vessels in the nuclear-energy plant;
b) The compression vessel chamber as an entirety or component in the rotary or reciprocating mechanical equipments (such as pump, compressor, turbine and hydraulic cylinder);
c) Frequently-transported vessels;
d) Vessels whose internal diameter (as for noncircular section, width, height or diagonal) is less than 150mm;
e) Directly-fired vessels. |
