On the calculation of horizontal jacketed vessels
Thread Content
Which item in SW6 is used for calculating horizontal jacketed vessels? Has anyone done this before? Only vertical ones were found.
From a standard perspective, there is currently no method available for performing routine calculations on horizontal vessels with jackets; the NB/T47042 standard also does not cover this type of structure, so it is not possible to use SW6 for such calculations. To calculate accurately, one can only use JB4732 for analysis. If an accurate calculation is not required, the external pressure on the inner cylinder can be calculated using a vertical setup; for the saddle support, the jacket can be used as the cylinder body, and the weight of the inner cylinder can be added as an additional factor. This is also a makeshift solution, though it will inevitably result in some significant errors.
When calculating sw6, it is necessary to calculate the inner and outer cylinders separately; special attention must be paid to the calculation of the external pressure on the inner cylinder and the inner end cap
