Web15 Sep 2014 · Thick walled vs. thin walled pipe is really a matter of their stress analysis, Theory of Elasticity, Lame’s Equations, and the various/different ways thin pipe vs. thick pipe buckle under external loading. This leads to two different design methods and slightly different thinking w.r.t. the two situations. WebThe theoretical treatment of thin cylinders assumes that the hoop stress is constant across the thickness of the cylinder wall (Fig. 6.1), and also that there is no pressure gradient across the wall. Neither of these assumptions can be used for thick cylinders for which the variation of hoop and radial stresses is shown in (Fig. 6.2), goodwill rayford rd spring tx
