Assuming that the analysis shown in the picture is correct (which it is), the wall thickness of a piping system under internal pressure is a relationship of its internal radius, the internal pressure and the values of the axial and hoop stresses induced according to the material selected. Let's break this down. Design Conditions. An essential part of every piping system design effort is the ...

wall thickness calculation. Justification: HDPE pipe will not rust, rot, pit, corrode, tuberculate or support biological growth. It has superb chemical resistance and is the material of choice for many harsh chemical environments [Ref. 7.2.4, p. 8]. Therefore, no mechanical or erosion allowance is required.

Pipe Wall Thickness. Barlow´s Formula is used to calculate the pipe pressure considering its diameter, wall thickness, and hoop stress (in the pipe material). Thus, it can be used to calculate whichever one of those parameters as a function of the other three.

Divide the total pipe wall thickness by two. The result is the size, or thickness, of one pipe wall. For example, if the total width of both walls is 1 inch, the size of one wall is 1/2 inch -- 1/2 = 1/2.

T = Pipe Wall Thickness (in) O.D. = Pipe Outside Diameter (in) SF = Safety factor (General Calculations 1.5 10, Use 1 For Bursting Pressure) S = Material Strength (psi) Ultimate Tensile strength or Yield strength can be used. Ultimate should be used to determine the bursting pressure.

E. Shashi Menon, in Transmission Pipeline Calculations and Simulations Manual, 2015. 2.4 Change of Pipe Grade: Grade Tapering. Similar to reducing the pipe wall thickness to compensate for lower pressures as we approach the next pump station or delivery terminus, the pipe material grade may also be varied. Thus the high pressure sections immediately downstream of a pump station may be ...
