Pipe diameter problem
Thread Content
Teachers, regarding the diameter of pipes, some people can tell what diameter a pipe is at a glance. Why can’t I tell the difference? Is there any good method here? Please give me your advice. Thank you!!!!
This is a matter of experience. You will naturally know it after a long time. If you have perseverance and make some cardboard by yourself to practice your eyesight every day, you will be able to tell the diameter of the pipe based on the size and curvature in a month.
There should be no shortcuts, but practice makes perfect. As long as you pay more attention and summary, and participate more in the maintenance and piping work of the equipment, I believe that in the near future, you will be like them, or even surpass them.
I really appreciate the help from the original posters!!
Thank you to the above two people. I am also a novice. I will practice more in the future.*
