Based on the production experience of pressure strengthening products for typical pressure vessels such as storage tanks,tank trucks and micro-bulk tank,combined with numerical simulation methods,modeling and analysis of typical low-temperature pressure vessel products are conducted.The pressure strengthening deformation laws of different low-tem-perature pressure vessel products are summarized,and the main factors affecting the pressure strengthening deformation a-mount are studied and analyzed.Experimental data is accumulated to correct the calculation results of corresponding prod-ucts,meeting the requirements of relevant products in production manufacturing.
