Pressure Vessels-Part 4. Fabrication, Inspection and Testing, and
Acceptance
1 Scope
1.1 This pa11 specifies the requ irements for the fabrication, inspection and testing, and acceptance of
steel pressure vessels within the applicable scope of GB 150. The requirements for the fabrication,
inspection and testing, and acceptance of pressure vessels made of other materials shall be in accordance
with the relative standards.
1.2 This pru1 is applicable to the structures of pressure vessels as fo llows. single-layer welded pressure
vessels, forged-welded pressure vessels, and layered pressure vessels (including concentric wrapped, "i.
integrated wrapped, flat steel ribbon wound, and shrink fit pressure vessels).
1.3 For low temperature pressure vessels made of austenitic steels (at design temperan1re lower than
- 196.C), the requiJements for the fabrication, inspection and testing, and acceptance specified
according to the negotiation of the patties participating in the fabrication shall be specified in design
documents by the design organization.
