Summer repairs without turning offs of the hot water
translation unedited
This task was placed before itself the Novosibirsk of power
engineering. And they successfully solve it. Positive changes in the supply with hot water of novosibirtsy felt
already by this spring. On the traditional spring tests of urban heating mains the inhabitants
were opoveshcheny previously. It communicated, that in the period of tests hotter the water supply will be ended
maximum on four days. Turning offs of hot water over the declared periods practical it did
not become. But the periods of turning offs sharply were reduced.
Repair was excellently carry ouied on the street of factory. Here along the roadway changed the pipes of the large diameter of main
teplovoda with the length of 300 meters. Work was conducted in two changes. Specialists comment on repair company.
Yu. Toy pistol, i.o. the chief engineer OF JOINT STOCK COMPANY "novosibirskenergo":
- the creation of new enterprise helped to principally in a new way
organize planned repair period. It is earlier for the modernization of this extensive section into 300
meters, as at the factory, not less than three weeks departed. All this time the inhabitants of houses, fed by hot water from this section of main, they sat without the hot water. Now, with the united owner of main and interblock networks, the possibility to use a unique system of Novosibirsk heat-mains
appeared, which makes it possible to feed users along other routes to the period
of the repair of basic. This diagram without turning off of users is used today practically in
all main sections, where repair work are conducted. Furthermore, we developed the new technology of the replacement of pipes in the
extensive sections, which gives the considerable savings of time. It they are in that, that the pipes for the replacement are prepared and are welded in the
lash previously on the edge of heating main. Then the replacement of old pipe to the new occurs during the week. But after replacement, without waiting until the end of works on the isolation of new pipe, to the filling in of heating main, on this section they release hot water. This technology reduces the periods of turning off to one week. Certainly, to use during the repair zakol'tsovannost' of the majority of urban
main routes, in order not to disconnect during their repair of users, - the matter is very complex. It is abutted against complex hydraulics of our routes, which must be considered. But we go to this. Especially as this possibility appeared with the creation of united
teplotransportnoy company "novosibirskgorteploenergo". Moreover, united enterprise for the operation of main and interblock networks
made it possible to sharply reduce the period of turning off of users
to the period of the repair of the sections of interblock networks. We formed the graphs of repair thus, so that the periods of the repair of supply mains would coincide with
the periods of the repair of interblock networks, fed from the overhauled main routes. This makes it possible to reduce the periods of turning off of users
to one week, during which is overhauled immediately the section of main route and
the section of interblock route adjacent to it. When by operation and with repair dealt different departments, to use a similar diagram it was impossible. Much time would depart to different interdepartmental agreements.
The Director-General OF THE PRIVATELY HELD COMPANY Of
"novosibirskenergospetsremont" A. Pronyushkin:
- in this case one should add, that appeared the united contractor in the person of our enterprise, which accomplishes repair of both categories of the routes: and main, and interblock. Certainly, in the present year the volumes sharply grew in connection with the
fact, that now we is achieved and the repair of interblock networks. But all resources for these volumes exist. It is nowadays planned to modernize 273 sections of interblock
networks. Their length of 26,8 kilometers. By the main routes one must replace the pipes of large diameter with a
length of 4,9 kilometers. In addition to this, we conduct works at the construction of new supply mains from the
Novosibirsk TETs-5 under the starting at the end of this year of new
sixth power unit, à òàêæå ðåêîíñòðóêöèþ ðÿäà íàñîñíûõ ñòàíöèé è öåíòðàëüíûõ òåïëîâûõ ïóíêòîâ (ÖÒÏ). Since the beginning of the year we already completed reconstruction
four TSTP.
The Director-General OF JOINT STOCK COMPANY
"novosibirskgorteploenergo" A. Kozhin:
- the creation of new enterprise, exploiting simultaneously main and interblock networks, - this is significant step forward in the reformation and company
herself "novosibirskenergo", and the municipal service system of Novosibirsk. The new principles of the operation (including of planned and special
repairs) of entire complex of the urban heating systems (with
exception of intra-house - they they remained in conducting of housing
and utilities services) - this, first of all, the considerable savings of operating costs, time to the repair work and, that is important for eksplutatsionshchikov
"novosibirskgorteploenergo", the additional realization of hot water in summer. Let us recall, that in the adjacent cities it as before is disconnected to a month or
two. And users do not pay this service, which bypasses power engineers not into one kopeck of losses.
The united owner above all heating mains - this is still and
qualitatively new responsibility. To now it not on whom shift - for entire complex with respect to the
guarantee of normal functioning of main and interblock networks bears
responsibility one company. And for their qualitative and rapid repair - also one company - united
contractor. Financing all repair work occurs due to the enterprise, it noted A. Kozhin, is comprised the graph of the entering of means to contractor. It is carried out by 100 percent. This is also one of the necessary conditions for the rapid and
qualitative fulfillment of repair work. For guaranteeing the special reliability of the system of heat supply
after the completion of all works on repair and modernization of
heating mains at the end of August will be carry ouied the still some
tests of networks for development and eliminating the "weak" places
before beginning heating season.
But thus far for the elongation of many kilometers of the heating
mains of Novosibirsk continue the stressed repair work.
