What wall thickness is required for pipes to be machined with standard external threads?
This depends on the diameter of the pipe you are processing; different diameters require different thicknesses； “\"Regular external thread\" should refer to pipe thread; it can be selected by consulting a table.
Reply to 2# A Pot of Fragrant Tea: Thank you for your answer. I would like to know the relationship between the outer diameter of the pipe and its wall thickness when machining M-shaped external threads on the pipe. Can relevant information be found there? If you have any materials, you can also send them to my email: owen517@126.com. Looking forward to good news!
First, it is necessary to determine what the pressure rating of your process pipeline is. If the wall thickness rating of the pipeline is SCH10, then the pipeline used for threading must be at least one grade higher; for example, SCH40 pipes should be used for threading. As we all know, once a pipe has threads cut into it, its wall thickness decreases, and as a result it no longer meets the wall thickness requirements of the original pipeline design. Therefore, pipes with a wall thickness one grade higher than that of the original pipe are needed to have threads cut into them.
There is no fixed value for this; it depends on the data of the thread you want to process. As long as the thread parameters do not affect the pipe, there will be no problem
