Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

The high-pressure heaters are the fundamentally necessary links of the second circuit of power units of nuclear power plants with light-water WWER-type reactors. They represent single-plane or two-plane pipe spirals of carbon steel. The paper presents the results of selection and mastering the mechanized welding technology for applying in the manufacture and restoration repair of high-pressure heaters. 20 Ref., 2 Figures.
Keywords: high-pressure heaters, spirals of high-pressure heaters, automatic welding, consumable electrode, electrode wire, mixture of shielding gases, technological equipment, rotary joints of pipelines, welding rotator
