Calculation for SW6 horizontal tank
Thread Content
When using SW6 to calculate horizontal vessels, if 20MnNiMo is selected as the material for the cylinder, an error message appears: \"When determining the allowable compressive stress at the design temperature in the saddle calculation, the external pressure curve for the cylinder material cannot be found.\" It is possible that the material temperature or B value is outside the operating range of the curve. ”What’s going on? How does everyone handle it?
When calculating horizontal vessels, the Sw6 software determines the safety performance of the vessel based on the selected vessel material and design parameters. When the 20MnNiMo material is selected, the error message indicates that the external pressure curve for this material cannot be found in the saddle calculation. This may be because the material temperature or B value is outside the operating range of the curve. To address this issue, there are generally two approaches: 1. Use other reliable material curves: It is possible to select other curves suitable for the 20MnNiMo material for calculations. You can consult the manufacturer or professional engineers to find out the available curve data, and then enter it manually into the software for use. 2. Consider changing the material: If suitable curve data cannot be found, consider changing the material. Other materials with complete curve data and high reliability can be selected for calculation. It should be emphasized that since container design and computing are related to safety performance, it is recommended to seek the advice and assistance of professional engineers or industry experts to ensure that the design complies with relevant standards and regulations. .
Neither 150 nor SW6 provides the external pressure stress coefficient curve for this material
20MnNiMo is not included in the GB150 system
