- Scope
- This standard specifies the design, manufacturing, inspection and acceptance requirements for pressure vessels made of nickel and nickel alloys. Normal pressure windows made of nickel and nickel alloys can also refer to this standard. 1.1 This standard applies to vessels with a design pressure not greater than 35MPa. 1.2 The applicable design temperature range of this standard is determined based on the allowable service temperatures of nickel and nickel alloy materials and their composite steel plates. The applicable design temperature range of nickel and nickel alloy lined vessels should not only consider the allowable service temperatures of nickel and nickel alloy lining and steel shell materials respectively, but also consider the difference in elastic modulus and expansion coefficient of lining and shell materials. 1.3 The following types of vessels do not fall within the scope of this standard: a) Vessels heated directly by flames; b) Vessels in nuclear energy installations; c) Pressure chambers that are part of rotating or reciprocating mechanical equipment (such as centrifugal pumps) casing, reciprocating pump cylinder, compressor cylinder, refrigerator cylinder, blower casing, centrifuge drum, etc.); d) Frequently transported containers; e) Inner diameter (for non-circular cross-sections, refers to the width, height or The diagonal line (such as the diagonal line of a rectangle and the long axis of an ellipse) is less than 150mm; f) Containers for fatigue analysis. 1.4 For pressure components whose structural dimensions cannot be determined using this standard, the following methods are allowed to be designed, but must be evaluated and approved by the National Technical Committee for Standardization of Boiler and Pressure Vessels: a) Stress analysis including finite element method; b) Difficult to Conduct experimental analysis (such as experimental stress analysis, difficult hydraulic test); c) Use comparable structures that have been put into use to conduct comparative empirical designs.
