What is the source of the relationship between pipeline diameter DN, wall thickness and pressure?
Thread Content
Hello everyone, I found the pipe wall thickness and pressure values corresponding to different pipe diameters DN on the Internet, but which national standard documents do these data come from? I checked the seamless steel pipe GB/T8163 and stainless steel seamless steel pipe GB/T14976 mentioned in this table, and found that it did not mention the wall thickness and pressure corresponding to the nominal diameter DN. Then I looked up the size and shape weight of GBT 17395-2008 seamless steel pipe. The relationship between the outer diameter and wall thickness was also mentioned, but the issue of the nominal diameter DN was not mentioned. So where does the data in this table come from, and whether it can be traced to a certain national standard document. Looking forward to your reply, thank you!
Received, thank you. I just checked and it does exist. In addition to this, are there any other standard number documents that also mention relevant content? Thanks.
There is a corresponding relationship between pipe diameter and wall thickness serial number Sch on HG20553. Sch10 roughly corresponds to 0.6Mpa. Select the wall thickness serial number according to the required pressure. However, HG20553 is divided into AB model pipes. We generally use B model. Please pay attention to this.
Help me, I’m here to learn* of. :lol
It is more convenient to check GB/T 12459 Appendix B
