Question about pipe wall thickness
Thread Content
There are 304-grade pipelines for desalinated water, with a DN200 size, a design pressure of 1.8 MPa, a design temperature of 110°C, and a test pressure of 2.7 MPa. Can I use a pipe with wall thickness SCH10s and a diameter of 3.76 mm?
The wall thickness is insufficient; at least Sch20S is required.
I need to calculate it: https://bbs.hcbbs.com/thread-2981135-1-1.html
It would be best to have relevant data to support it, as that makes it more reliable!
Calculated using the wall thickness formula with a corrosion margin of 0, the resulting wall thickness margin is not large. However, the strength and minimum wall thickness requirements are met, the medium is not hazardous, so no excessive margin needs to be considered
