Introduction to Equipment Material Selection
Thread Content
Are there any materials related to **standards for selecting equipment materials, such as chemical industry standards or petrochemical industry standards? For example, are there any guidelines regarding the selection of materials like Q235 and 1Cr5Mo?
For this, it generally relies on experience; I really haven’t seen any kind of standard or anything like that. There are many factors to consider when selecting materials; one of them is cost-effectiveness ； Second is operability (corrosion, processing techniques, etc.)
You can take a look at HG/T20581 \"Specifications for the Selection of Materials for Steel Chemical Process Vessels\"
SHT 3129-2012 Guidelines for Material Selection in the Design of Equipment and Pipelines for High【Acid】Crude Oil Processing Units; SHT 3096-2012 Guidelines for Material Selection in the Design of Equipment and Pipelines for High【Sulfur】Crude Oil Processing Units – Part IV: Corrosion and Protection of Petrochemical Equipment! ! ! ! ! ! ! ! ! ! ! ! !

There are corresponding standards for the material selection of general equipment! It won’t be based solely on experience
Different device materials are selected based on the type of medium. The corresponding **standards are also just an overview; it’s impossible to cover them in complete detail!
The scope of this question is too broad. . . .
