What is the wall thickness of a seamless steel pipe with a pressure of 40 MPa and a DN50 diameter? Waiting online

I’m asking the experts here; it’s urgent, waiting online
Without the material information regarding steel pipes, it’s impossible to do the calculation
This falls under the ultra-high pressure category; it is recommended to have the relevant professionals from the same organization and those responsible for the design issue out a formal specification. This isn’t something that can be said casually; it involves pressure welding inspection, pressure testing, and a whole range of construction qualifications. For reference.
For a pipeline with such high pressure, don’t you need a designer?
Check GB150 – it covers the allowable stress of pipeline materials at operating temperatures, as well as the weld factor. The formula is: Pipeline thickness = (design pressure * inner diameter of the pipeline) / 0.5 * weld factor * allowable stress of the material at the design temperature. A weld factor of 1 is used for 100% flaw detection, while 0.85–0.8 is used for partial flaw detection. That’s roughly all there is to it; construction must be carried out only after referring to the relevant standards, as there are many details involved
I don’t visit this website very often. If you need any information, you can contact me via WeChat at yfl20179. Be sure to mention HaiChuan Chemicals or something similar; I can provide you with some electronic versions of the **standards, for free! !
**I’m not sure if there is a table in the standards for steel pipes that shows the relationship between pressure and wall thickness
Without knowing the operating temperature, medium properties, corrosivity, whether it is a gas or a liquid, and whether there are particles present, how can I perform the calculation? Based on experience, and considering the data available at present, as a precaution, the wall thickness of this pipe should be XXS or higher
