How should the resistance coefficient or equivalent length of expansion joints be determined when calculating hydraulics?

I would appreciate some guidance from those who know more O(∩_∩)O Thank you
There’s not much of it, right? Does this even count? Should we turn on a valve just to be safe? You still need to take into account the excess amount after doing the calculations…
The resistance coefficient of expansion joints is generally determined in accordance with the \"DL/T5054-2016 Code for Design of Steam and Water Pipelines in Thermal Power Plants\". Don’t laugh – it’s not a standard from the petrochemical industry; it’s from the power industry. Appendix D of this standard provides detailed information on the resistance coefficients or calculation formulas for the Soviet Union, the United States, and Germany. As for expansion joints, there are no data provided by the Americans; only those from the Soviet Union and Germany are available. First, look at the Soviet one: then look at the German one: pay attention to the metal hose compensator – it’s quite tall. . . Attach a standard cover again. .
The design specifications for pipelines in thermal power plants include one set of regulations for steam and water pipelines, and another set for flue gas, air, and coal powder – commonly referred to as the six-set of regulations. Mastering these two sets of regulations covers most aspects related to pipelines. In comparison, it is actually more systematic than things in the chemical industry. .
The master truly understands the mysteries of heaven and humanity; to be able to find such things is amazing. Thank you
