Selecting pipe wall thickness.The fluid flow equations and formulas presented thus far enable the engineer to initiate the design of a piping or pipeline system, where the pressure drop available governs the selection of pipe size.In addition, there may be velocity.
Sdr - standard dimension ratio - and pipe series - s - it is common to use the standard dimension ratio - sdr - as method of rating pressure piping stainless steel pipes - dimensions and weights ansiasme 36.19 - dimensions, wall thickness and weights of stainless steel pipes according to asme b36.19 - stainless steel pipe.
MoreCalculation of structural minimum thickness of pipe - posted in refining, hydrocarbons, oil, and gas as per section 11.1.3 of api 574 in low-pressure and low-temperature applications, the required pipe thicknesses determined by the barlow formula can be so small that the pipe would have insufficient structural strength.For this reason, an absolute minimum thickness to prevent sag, buckling.

More3a of the code eq.4.2 here.Further, inside-diameter-based formulas add 0.6 times the thickness to the inside radius of the pipe rather than subtract 0.4 times the thickness from the outside radius.Thus, the inside-diameter-based formula in the pressure vessels codes and eqs.3a and 3b of asme b31.3, the piping code, are consistent.
MoreThe design selected thickness is always greater than the minimum wall thickness i would hope.After calculating the min wall thickness the pipe schedule needs to be selected to be greater than the minimum wall thickness.Also you need to consider the pipes structural strength.
MoreMinimum wall thickness for pipes can also be based on american society of mechanical engineers standards asme b31.4 and b31.8.If the minimum wall thickness based on asme standards is greater than the calculated minimum wall thickness, you may be legally required to use the minimum wall thickness given in the asme standard.
