To determine the cause of defects, the work performed was checked for compliance with the adopted design decisions, as well as an analysis of the design decisions themselves. It was found that the cause of defects during operation are errors in the adopted design decisions.</p>heat supplyheating networkcompensatorbellows-typetemperature expansionтеплоснабжениетепловая сетькомпенсаторсильфонтемпературное расширение[Titov G.I., Demina Yu.E., Zelentsov D.V.
