Factors affecting the operational reliability of heat networks during periodical hydraulic testing (pressure testing) by higher pressure. Analysis of damage of Kiev heat network piping during 2002 – 2017 has been performed and deficiencies of normative documents have been noted as regards the procedure of performance of periodical hydraulic testing by higher pressure. Influence of defects has been considered and an approach has been proposed for determination of testing pressure, in order to achieve the specified reliability of operation of pipelines with defects. Ref. 14, Fig. 4.
