This post was last edited by Xiao Jie on 2016-1-1 08:03. When the design pressure of a pressure vessel reaches 10 Mpa, what type of internal cylinder should be used, as well as what kind of end cap, and where to find the relevant information. I checked the \"Pressure Vessel Design Manual,\" and the design pressures specified in it don’t reach such high levels. Where should I look? ? Urgent, urgent, urgent! Need expert advice :(
One of the books in the series on chemical engineering design is titled \"High-Pressure Vessels\", which the original poster might find useful as a reference.
Generally, the cylinder body is made by rolling steel plates, while the head can be spherical or elliptical.
In Central Asia? It mainly involves the design of pressure vessels with pressures within the range of 5 Mpa to 10 Mpa
Do you know what the general maximum allowable design pressure for that elliptical head is? Where can I find it? Thank you for your help!
There are no specific limitations; the dimensions and thickness of the head cover must be calculated based on the specific design parameters of the container, with the design choices being determined independently. For large-diameter containers, it is best to use spherical end caps; otherwise, elliptical end caps are too thick, making both material selection and processing difficult.
Well, it’s like this. I want to create a buffer tank; the pressure entering the tank is likely around 5–10 Mpa. I just need to do a preliminary selection of suitable options, without needing a detailed design. All I need to determine is the length and height of the tank, as well as the type of end cap, under the condition of ensuring that pressure is maintained. What I’m most concerned about is whether a cylindrical shape can ensure the required pressure conditions, and whether an elliptical head can do the same. Thank you for the guidance!
The cylinder body is fabricated from steel plates, while the end caps are spherical or elliptical in shape; the specific dimensions are determined through finite element analysis
Just calculate it. Either elliptical or spherical is fine; compare the production costs of the two.
It depends on whether there are any requirements regarding operational space for the buffer tank. Spherical heads take up more space; however, at 5 MPa, an elliptical head is preferable, while at 10 MPa, a spherical head is better suited. However, the manufacturing cost of spherical end caps is relatively high, and elliptical end caps require a greater thickness. It needs to be considered comprehensively.
