[Help] Seeking the pipeline material grade specifications of the Dalian Design Branch of China National Petroleum Engineering Corporation
Thread Content
I am looking for the specifications regarding the grade of pipeline materials used by the Dalian Design Branch of China National Petroleum Engineering Corporation, such as 5B11, 10B2, etc. I need this information to prepare a ledger for the pipelines in my factory; however, I only have a list of the pipelines and not the specifications for their materials. If it’s inconvenient to send this information here, you can send it to my email address: 1438938325@qq.com. Thank you in advance; I really need this information urgently.
You can ask Dalian Design Institute for it
How can there be a grade like 5B11? . .
They do indeed have such levels in their designs; each design institute is different
If I knew someone from Dalian Design Institute, I wouldn’t need to ask for help here.
I have two levels, but they’re not what you want. . .
