SW6-2024 V1.0 Patch 2 (standalone version) and (network version) resolve the following issues: 1. The allowable stress values for certain materials in the standard material database are incorrect； 2. For external pressure calculation scenarios, an option to select “scenario attribute” (long-term scenario or short-term scenario) has been added to the interface. 3. Cylinder: 1) When calculating the external pressure cylinder, if the user enters a negative deviation exceeding a certain value, an error occurs in the calculation ； 2) For external pressure stiffeners, when the steel section type is customized by the user, it is not possible to select the material for the stiffener ； 3) The distance from the centroid of the T-shaped steel reinforcement ring to the top is incorrect. 4. Head: 1) The external pressure cone shell reinforcement ring always shows that the cross-sectional dimensions are not up to standard ； 2) For the calculation of the bolted flat cover, the bolt load shows a very high value, and it is indicated that the bolt area is not satisfactory. 5. Opening reinforcement: 1) For elliptical heads, it allows users to input a smaller reinforcement width B in order to meet the condition that both the opening and its reinforcing metal are located within 80% of the sphere centered on the head (the same applies to dish-shaped heads) ； 2) When calculating dmaxC, the additional shell thickness should be taken into account, rather than the additional nozzle thickness. 6. Flange: 1) An option has been added to the interface allowing the user to select “With successful usage experience; stiffness verification exempted” ； 2) A calculation report cannot be generated when checking wide-flange fittings ； 3) When the flange calculation is unsuccessful, the allowable stress of the flange material at its design temperature, as output in the calculation report, may sometimes be incorrect. 7. Components: 1) Weld ring gaskets to seal the flanges; the calculation sheet is unable to determine the axial load and external torque ； 2) Flexible tube sheet: calculation errors occur when there is negative pressure in the tube side. 8. Horizontal containers: Sometimes, it is not possible to start and run horizontal container programs. 9. Asymmetric double saddles and multi-saddles: 1) Single pressure chamber, three cylinders with different wall thicknesses; the type of pressure test for all is hydraulic testing, but in the calculation documents, the pressure test type for the intermediate cylinder becomes pneumatic testing ； 2) When the head type is a flat cover, the data for the connected cylinder has also been entered; however, it still indicates that the cylinder data has not been entered and that the calculation cannot be completed. 10. Vertical containers: 1) When there are too many nozzles, the results displayed on the screen are incomplete when calculating the overall equipment ； 2) Semi-circular tube jacket; the test pressure value determined by the program is incorrect ； 3) When calculating the lower head of a semi-circular tube jacketed vessel, the external pressure was calculated mistakenly using the jacket pressure. 11. Towers: 1) When there are multiple flanges, the design pressure of several of these flanges is shown as 0 ； 2) When the skirt seat overlaps with the cylinder, the allowable shear stress value at the welding joint is shown as 0 ； 3) The unit of bending moment in the calculation book is incorrect ； 4) For H/D=0.16, the program did not calculate the vertical seismic force ； 7) In the interface, “Height from the intermediate support to the ground” should be changed to “Height from the intermediate support to the foundation”, and “Height of the flange sealing surface from the ground” should be changed to “Height of the flange sealing surface from the foundation”. 12. U-tube heat exchanger: 1) It is not possible to perform calculations for strengthening the openings in the rear end head ； 2) Tube box flanges – sometimes the standard flange database cannot be accessed. 13. High-pressure vessels: When performing equipment-level calculations, opening reinforcement cannot generate a calculation report. 14. Overpressure relief device: The gas compression coefficient Z has been changed to allow users to input it themselves.
