The number of legs should be specified based on the size of the tank.
One is based on the size and length of the horizontal container, and the other is based on the material strength of the container.
Try not to use three saddles as the statically unstable structure is prone to problems. The 1,000-cubic-meter horizontal tanks all have double saddles.
When the length of the container is too long, the stress on the two supports will be too great, and when it is uneconomical to increase the thickness of the cylinder, a three-saddle should be used.
NB/T47042:1, when the cylinder length is too long, you can consider setting； 2. When using 3 saddles for support, the middle saddle should be fixed and the saddles at both ends can slide. ； 3. The saddle setting should consider the overall stress of the container and perform strength calculations.
If the calculation of two saddles fails, you can consider three supports.
Cylinder length to diameter ratio, pressure load, vibration shape
