DetailsASME B31.1 is also bundled with ASME B31.3-2020: Process Piping as the Power and Process Piping Package. Changes to B31.1-2020. The previous iteration of the standard for power piping, which was released in 2020, was also a sizable revision. ... Revised equation for the minimum wall thickness of straight pipe under internal …
DetailsBends were required to have, after bending, a wall thickness at least equal to the minimum required wall thickness for straight pipe in para. 304.2.1. However, this was changed in the 2000 Addendum. The Lorenz equation (ca. 1910) was included; it provides a means of calculating the required wall thickness. Note that the prior …
DetailsThe course on Pipe Thickness Calculations w.r.t. ASME 31.1, 31.12, 31.3 has been developed to explain the fundamentals of Pipe thickness calculations, also the thickness calculations for High pressure & external pressure are explained in detail. The content is organized in a systematic manner so that the first timers can also understand. Course …

DetailsPipe Elbow Minimum Thickness Requirement; ... A reducing elbow is a type of pipe elbow used in piping systems to change the direction of flow while also reducing the pipe diameter or size in the process. It combines the functions of a standard elbow, which redirects the flow, with that of a reducing coupling or adapter, which …
DetailsReduction of RO noise can be achieved by either source control (preventing the noise generation) or path control (pipe insulation, silencers or increasing pipe schedule). Source control is a more effective method, thus preferable. Sound, once generated, propagates virtually unattenuated in the downstream pipe.
