Horizontal tank design
Thread Content
Recently, in a design project, I encountered a single-tank vessel; the material used for this vessel is 16MnR, the design pressure is 1.1 MPa (G), the design temperature is 60°C, and a corrosion allowance of 3 mm is required. The external dimensions of the vessel are 6500 mm X 13600 mm, with the two end caps being of the 2:1 standard type. I wonder if there are difficulties in manufacturing such a large device.
Is it a diameter of DN6500? There will be no problems with manufacturing! There are existing similar engineering examples. For manufacturing, I don’t think there’s much difference between vertical and horizontal types; design is actually the key factor!
The design is in accordance with JBT4731-2005 for steel horizontal vessels, and manufacturing should take into account on-site execution. Strength calculations can be carried out using SW6-1998v4.0, which is very convenient. This post was last edited by dnldnl on 2007-12-21 at 13:22.]
Attached is the standard JBT4731-2005 for steel horizontal containers: http://bbs.hcbbs.com/viewthread.php?tid=5341&highlight=%B8%D6%D6%C6%CE%D4%CA%BD%C8%DD%C6%F7. This post was last edited by bobo315 on 2008-12-4 at 14:04.]
For manufacturing plants that have a certain scale and the necessary qualifications, such equipment is extremely easy to handle; the only thing to worry about is the shipping of the equipment.
Consider the support and lifting issues; while meeting the strength requirements, increase the wall thickness to ensure the stiffness of the equipment. Especially the middle section. Last edited in this post by iamsunyue on 2007-12-21 15:56]
Purchasing the end caps and transporting the entire equipment should be somewhat challenging. Which factory can manufacture elliptical end caps with dimensions of 6.5m x ~30mm? It might not be easy.
Why was such a large horizontal tank chosen, and what is its economic efficiency?
Since the pressure of the storage medium at room temperature is around 5–6 kgf/cm2, and a certain storage period is required, such large-sized equipment is necessary.
~Our company can handle diameters of up to 4200 at most; your 6500 is really large – we need to consider transportation or the need for on-site fabrication, and heat treatment would also need to be taken into account if required.
Manufacturing is no problem; the main issue is transportation.
There’s definitely no problem; it’s not that big anyway
