WebSecondary Stress. Thermal expansion and contraction happens when a pipe heats up and cools down. The piping system must have enough flexibility to handle the expansion. Two horizontal pipe loops between fixed anchors. These pipes are subject to high temperature expansion. Deflection of the piping system caused by thermal expansion. Webpressure in a piping system with vapor flow. The acoustic pressure is usually created from pressure-reducing devices due to high pressure drops and mass flows of vapor services. These acoustic energies excite the pipe wall circumferentially due to high-frequency sound waves in the range of 500–2,500 Hz, where most of the energy is captured.

WebStyles and Principles of Operation. Control valves may be either two-way (one pipe in and one pipe out) which act as a variable resistance to flow or three-way (two pipes in and one out for mixing valves – one pipe in and two out for diverting valves) as depicted in Figure 1.
