A Vacuum pipe is a pipe which its inside space is entirely devoid of matter. Thickness or diameter of the vacuum pipe is dependent on vacuum load per linear length of pipe and internal vacuum pressure. The below section of this page provides you the online vacuum pipe thickness calculator which helps you to calculate vacuum pipe’s diameter by just entering the input values such as vacuum load per linear length of pipe and internal vacuum pressure.
What is the vacuum pipe thickness for the vacuum load per linear length of pipe with 13 pound/ft and an internal vacuum pressure of 15 pound/foot2?
D = 12 x (13 / 15)
