It is often the cases that the temperature of the piping system is not constant throughout the operating cycle, or there is potentially more than one operating cycle (i.e., pump A on, pump B on, both pumps on, both pumps off). In these cases it is common to find that the temperature rises on some occasion to a maximum value, say Te; then, as events occur during the normal course of operation the temperature varies between Te and other lower temperature states, say T1, T2,...,

1- Many of the non-power codes separate the in-plane and the out-of-plane stress intensification factors (and do not intensify torsion). For the power codes the SIF's can be computed for in-plane, out-of-plane, and torsional moments using SIF = 0.9 / h^2/3. For the petrochemical and other non-power codes: 2- The power codes do not recognize the extruded welding tee, the sweepolet, or the weldolet. The non-power codes do, and if any of these fittings are used in a power appli

The source article discusses the historical Canadian CSA Z183 (oil pipelines) and CSA Z184 (gas pipelines) standards. These were consolidated into CSA Z662, so the video will explain that transition and use CSA Z662:23 for the engineering examples.
