For fastening various types of flanges, there is a recommended range of torque values. I would like to know if there are any standard documents such as GB XXX, SH XXX, or ASME XXXX that can be used to determine the approximate torque range If there are any regulatory documents in this regard, please let me know the standard numbers, thank you!

It should be the manufacturer’s specifications for bolt tightening, right?

The information can be found in “Torque Calculation for Torque Wrenches” and the “Operation and Maintenance Manual for Hydraulic Wrenches”

I checked ASME PCC-1-2010, and it seems that this 88-page standard does not contain any recommended values in this regard: Q

There are recommended torque calculations in the appendix
