During the design of pressure vessels at normal pressure, why are reinforcement rings needed, and what is their function? This post was last edited by tulongshao on 2007-12-10 12:51]
Reinforcement rings are not added at all times! It also depends on the circumstances.
Then why are reinforcement rings needed? Under what circumstances are they used?
Atmospheric pressure vessels require consideration of stiffness; if the stiffness is insufficient, reinforcement rings must be used to compensate.
For the poster, should the reinforcement ring be a reinforcing rib for the square tank, or a reinforcement ring for the pipe connection?
I’m not really sure about this specifically either
Perhaps your container has a too large diameter, operates at atmospheric pressure, and is made too thin with insufficient stiffness, which is why reinforcement rings were added! At normal pressure, it is generally not added. But it’s necessary to add them for large equipment; sometimes just a few turns of angle steel rings are enough! I encountered containers required by Japan to be made of stainless steel; all of them used 3mm thick steel plates, with frames made from angle iron!
To ensure stiffness and prevent instability.
I’ve learned something – this forum is really great!
For atmospheric-pressure vessels with thin wall materials, if the diameter is large, their stiffness must be taken into account; therefore, reinforcement rings are generally required, although they may not be necessary if the stiffness requirements are met.
For a pressure vessel with a fixed diameter, increasing the wall thickness of the vessel or reducing its calculated length can both effectively enhance its load-bearing capacity. On thinner cylinders, it is more economical and reasonable to install rigid members to reinforce the cylinder in order to increase its critical pressure, rather than simply increasing the wall thickness. In practical engineering, a certain number of reinforcement rings are generally installed on the cylinder. If the cylinder is made of materials such as stainless steel, copper, or aluminum, installing a reinforcing ring made of ordinary materials like carbon steel around the cylinder can **reduce the cost of manufacturing equipment. The reinforcement ring should have sufficient stiffness; it is usually made of flat steel, angle steel, I-beam, or other shaped steels, with carbon steel being the most common material used.
