Strain strengthening technology added to large-capacity specifications
Thread Content
New strain strengthening technology has been added to the large-capacity specifications; it is not known which companies are already using it. This technology is primarily intended for low-temperature cryogenic equipment, and colleagues from manufacturers and design firms in the group are welcome to participate and discuss it
Austenitic stainless steels have a low yield strength; when designed according to GB150, the safety margin is too large, which prevents them from fully utilizing their load-bearing capacity and leads to waste. When austenitic stainless steels are stretched to plastic deformation at room temperature and then unloaded, their yield strength increases upon being loaded again. This enables the use of technology in cryogenic equipment to reduce thickness and weight, thereby saving energy and reducing consumption. Regarding the application of this technology, how exactly is it carried out? For example, the selection of allowable stress values during design, the requirements and methods during manufacturing, and the manufacturing processes. Requirements for testing. Experienced comrades must speak up actively to make progress together.
It is mainly used in low-temperature insulated pressure vessels...
