Coupling definition

Coupling means the complete assembly, and shall include the gasket, clamps, bushings, shear rings, and any other part required to make a joint meeting specifications;
Coupling means a connector used in joining a piping, tubing or hose system.
Coupling means a tubular section used for the exclusive purpose of joining two threaded pin ends of pipe or equipment having the same external and internal diameters and same thread.

Examples of Coupling in a sentence

  • With mutual agreement, the Area EPS Operator and Customer may determine a point between the Point of Common Coupling and Point of DER Connection.

  • Point of Common Coupling (PCC) – The point where the Interconnection Facilities connect with the Area EPS Operator’s Distribution System.

  • Distribution Upgrades – The additions, modifications, and upgrades to the Distribution System at or beyond the Point of Common Coupling to facilitate interconnection of the DER and render the distribution service necessary to affect the Interconnection Customer’s connection to the Distribution System.

  • Reference Point of Applicability – The location, either the Point of Common Coupling or the Point of DER Connection, where the interconnection and interoperability performance requirements specified in IEEE 1547 apply.

  • The nameplate ratings referenced in the Interconnection Process are alternating current nameplate DER ratings at the Point of DER Coupling.

Coupling in the Cambridge dictionary means “a device that can join two things together”. However, in a classical watch, it refers to the place where the rotation of one wheel causes the rotation of a second wheel. And in this case the rotation frequencies of the two wheels have a fixed ratio. Similarly, this kind of coupling also happens in the central metabolic pathways. Take the classical glycolysis pathway for example. There is a fixed ratio of ATP per lactate produced. There are 11 reactions from glucose to lactate, two molecules of ATP are consumed for the production of glucose-6-phosphate and fructose-1,6-bisphosphate, and 4 molecules of ATP are generated in the production of 3-phospho-glycerate and pyruvate, so that the ratio of ATP per lactate is normally fixed at 1. The oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH2 to O2 by a series of electron carriers. In this process, many people think that the number of protons pumped by the terminal oxidase per oxygen is always the same. However, this coupling between proton pumping and electron transfer, may not always occur at a fixed ratio. It may be regulated by the cells, either kinetically or through gene expression, in order to enhance the robustness of the cells.
