The main goal at this stage of operation is the absence of significant reconstruction measures to improve the reliability of the system.</p> <p><strong>Materials and methods:</strong> Work has been carried out to analyze the probability of triggering, the failure rate and the probability of failures of gas supply systems for single indicators.</p> <p><strong>Results:</strong> To ensure the reliability and durability of gas boilers during replacement, the following 8 different measures were proposed.</p> <p><strong>Conclusion:</strong> The article proposes a closed circuit, the introduction of network redundancy in the system by ringing or duplicating elements and considers the social nature of gas distribution systems.</p>gas distribution networksreliabilityrangedurabilitymaintainabilitygas pipeline sectiongas control points, gas distribution pointsгаз таратушы желілерсенімділікәсер ету радиусыберіктікжөндеуге жарамдылықгаз құбырының учаскесігаз реттеу бекеттерігаз тарату бекеттерігазораспределительные сетинадежностьрадиус действияпрочностьремонтопригодностьучасток газопроводагазорегуляторные пунктыгазораспределительные пункты1.Bunchuk VA.
