Low-temperature storage tank
Thread Content
The graduation project is a horizontal storage tank for liquid nitrogen at low temperatures. I would like to ask whether the inner tank and the outer tank are calculated separately during the design process? Also, does the wall thickness of the cylinder need to be the same as that of the head? The current calculated wall thickness is 19 mm, but no corresponding thickness can be found for a standard elliptical head with a diameter of 3200 mm. Should I choose a different wall thickness then?
Are the inner cylinder and the outer cylinder calculated separately? Calculate separately; when determining the internal pressure of the inner tank, take into account that the interlayer is vacuum. The outer tank is checked for negative pressure. Also, does the wall thickness of the cylinder need to be the same as that of the head? (It is usually the same.) The current wall thickness specified is 19 mm; for this thickness, even-sized plates are generally used, that is, 20 mm

A graduation project is an excellent opportunity to learn; one can refer to relevant standards, which makes the learning process more efficient than seeking help in a random manner. There is something commonly known as “container regulations”; its full name might be Pressure Vessel Design Specifications. When presenting the design, bring up more provisions from GBxxxx – that will immediately make the work seem much more sophisticated
