Damage Pattern Recognition of Pressure Equipment
1 Scope
This document gives the damage description and damage mechanism, damage form, affected materials, main damage mode identification of pressure equipment.
Influencing factors, devices or equipment prone to occur, main preventive measures, detection or monitoring methods, other related or accompanying injuries, etc.
This document applies to damage pattern recognition of pressure equipment.
This document does not apply to the failure of the seal of the pressure equipment, the failure of the safety interlock device, and the failure of the pressure relief device.

3 Terms and Definitions
There are no terms and definitions that need to be defined in this document.
4 General provisions
4.1 The damage mentioned in this document refers to the damage caused by the pressure equipment under external mechanical load, medium environment, thermal load, etc. alone or in combination.
Degraded material properties, structural discontinuities, or reduced load-carrying capacity.
4.2 This document divides damage modes into the following categories. corrosion thinning, environmental cracking, material deterioration, mechanical damage, which have not yet been classified into the above damage categories
Others are included in other damages, and the damage mode index of pressure equipment is shown in Appendix A. The damage categories are divided as follows.
a) Corrosion thinning. The wall thickness is thinned due to mass loss of metal under the action of corrosive medium.
b) Environmental cracking. the cracking of the material under the action of the service environment. Environmental cracking mainly includes stress corrosion cracking, and hydrogen infiltration
Caused by hydrogen bulging and hydrogen-induced cracking.
c) Material deterioration. The microstructure and mechanical/corrosion resistance of the material are degraded due to the service environment.
d) Mechanical damage. The bearing capacity of the material decreases under the action of mechanical load or thermal load.
e) Other damages. damage patterns not classified into the above four categories.
4.3 There are differences between individual injuries and sometimes do not fully match the typical injuries described in this document. When there are multiple injuries or
When damage is coupled, it is necessary to identify the dominant damage or the coupling effect of the damage.
4.4 This document starts from damage description and damage mechanism, damage form, affected materials, main influencing factors, prone devices and equipment, main
Eight aspects of preventive measures, methods of detection or monitoring, and other related or concomitant injuries are described. Typical Process Packages Under Pressure
See Appendix B for the equipment damage distribution map.
4.5 Personnel or teams engaged in damage pattern recognition shall have relevant foundations in materials science, corrosion and protection, chemical technology, mechanics, monitoring and testing, etc.
