Working drawings of heating networks

 Working drawings of heating networks.

 The heat carrier is network water with a temperature of 95-70°C.

 The total length of the designed networks is 70 m.

 The heat supply system is closed, two-pipe, the regulation of heat energy supply depending on the   outside temperature is carried out in the boiler room (high-quality   regulation).

The laying of the heating network is adopted above ground on low and high supports.

Connection to the existing heating network ∅159x4.5 is provided in the heat chamber. Turns of the heating network are used as compensators.

At the lowest points of the pipelines, drains are installed, at the upper points - air vents.

Type of fixed supports - frontal two-thrust according to series 4.903-10 issue 4,

movable - sliding supports according to series 4.903-10 issue 5.

 Pipeline  material -  longitudinal electric-welded steel pipes according to GOST 10704-91* made of    carbon steel grade St20.
