Horizontal container saddle
Thread Content
There is a buried tank with a horizontal inner cylinder of DN2400X8 made of Q345R material, and an outer cylinder of DN2500X8 made of Q235B material. The length of the outer cylinder is 10050 mm. The strength of the inner cylinder, outer cylinder, and saddles, as calculated, is sufficient. The center distance between the saddles is 9000 mm. I would like to ask whether SW6 takes into account the possibility that such a large center distance between the supports could cause instability of the cylinder, and whether it is necessary to add another support in the middle I also hope the expert will not hesitate to share his insights! !
According to the description, the strength of the inner cylinder, outer cylinder, and saddle has been calculated; however, whether the possibility of cylinder instability due to an excessive center distance between the supports has been taken into account needs to be determined based on the specific requirements for saddle calculation in SW6. Under normal circumstances, the saddle design of horizontal containers must meet the following requirements: 1. The number and location of saddles should be calculated and determined in accordance with relevant standards, in order to ensure the stability and safety of the container ； 2. The center distance between the saddles shall meet the specification requirements to prevent instability of the cylinder ； 3. The size and design of the saddle also need to meet regulatory requirements in order to bear the weight of the container and external loads. Regarding the calculation of the saddle in SW6, I am unable to provide specific details or opinions; it is recommended to refer to relevant design specifications or consult a professional engineer for verification. If the center distance between the saddles is too large, it may be necessary to add additional supports or take other measures to improve the stability and safety of the container. .
Thank you; the saddle is not completely standard, but it can pass the SW6 calculations. There shouldn’t be any major problems now.
Using multiple supports results in complex stress conditions for the cylinder, making calculations difficult; however, their proper use can save material and reduce the complexity of equipment manufacturing. With two supports, the cylinder thickness increases, and calculations should be feasible, though it is not economical. But no one performs calculations for multiple supports according to the standards.
