Increasing the container wall thickness, reducing the container height, and adding reinforcing ribs are the most economical and simplest solutions.
To increase the critical pressure of external pressure vessels, methods such as (increasing wall thickness) and (adding reinforcing rings) can be employed, among which the (adding reinforcing rings) method is more economical.
Increase wall thickness; add reinforcement rings – this is an economical method.
Install reinforcement rings and increase the wall thickness of the cylinder; install reinforcement rings
Increase wall thickness, add reinforcement rings, add reinforcement rings
To increase the critical pressure of external pressure vessels, methods such as (thickening the wall) and (adding reinforcing rings) can be employed, among which the (adding reinforcing rings) method is more economical.
Increase wall thickness and install reinforcement rings； Let the reinforcing ring economy be…
Increase wall thickness, add reinforcement rings, add reinforcement rings
A cylinder with a length greater than the critical length is considered a long cylinder. The end boundaries or ends of the oblong cylinder do not provide any reinforcing support for its middle section; its critical pressure is independent of the cylinder’s length. When the cylinder becomes unstable, its cross-section changes from circular to wavy, with the wave number equal to 2. A cylinder with a length smaller than the critical length is considered a short cylinder. The end boundaries or end caps of a short cylinder can provide reinforcing support for its middle section, and its critical pressure is inversely proportional to the cylinder length. During instability, the cross-section of the cylinder takes on a wavy shape, with the number of waves being greater than 3. For long cylinders and short cylinders with the same diameter and wall thickness, the latter has a higher critical pressure than the former. Changing the long cylinder to a short cylinder can increase its critical pressure. Strengthening rings are installed on externally pressurized cylinders in order to transform long cylinders into short ones or to reduce the calculated length of cylinders, with the aim of improving the stability of the cylinders. This method directly increases the cylinder thickness to save material, reducing the weight by about 1/3. For stainless steel cylinders, it is more economical to use a carbon steel reinforcement ring placed on the outside. Furthermore, the reinforcing ring can also reduce the impact of shape defects in large-diameter thin-walled containers, thereby improving the reliability of the structure. In summary, to increase the critical pressure of external pressure vessels, methods such as (reducing the calculated length of the cylinder) and (increasing the thickness of the cylinder) can be employed, among which the method of (reducing the calculated length of the cylinder) is more economical.
