Example How to Design Thin-Walled Vessel under Internal Pressure

Rifka Aisyah Leave a comment

In this post, I want to share a simple example on how to design thin-walled vessel under internal pressure. Please check my previous post about the method on how to estimate minimum thickness of vessel component (shell, flat end closures, domed head closures).

Example

Estimate the thickness required for the component parts of the vessel shown in the diagram.

How to Design Thin-Walled Vessel under Internal PressureThe vessel is to operate at a pressure of 16 bar (absolute) and design temperature of 300oC. The material of construction will be plain carbon steel. Welds will be fully radiographed. A corrosion allowance of 2 mm should be used. Read More

In this post, I want to share how to design thin-walled vessel under internal pressure. I will also share a simple example about the application in the next post.

For information, I do not have any experience of the calculation in my whole career until posted this post. The design of thin-walled vessel under internal pressure is usually job of mechanical engineer. But it is good for process engineers to understand it in general.

The design of thin-walled vessel under internal pressure, in general, will be divided into two parts: design of cylinder and spherical shells and design of heads and closures. Read More
