Steam pipeline for Ministry of Justice


The new location of the Ministry of Justice and The Square of Justice, is located in the area of the former barracks, and borders the Selski Road, Baron Filipovic’s Driveway and Cankareva Street.

The DN 150 junction is connected to the existing main steamer DN 300 in pane No. 1, located in a green belt on the south side of Baron Filipovic’s driveway. Under the roads (Access to Baron Filipović and Selska cesta) steam is led through the anti-security pipes DN 350.

The steam is led in the classic concrete channel to the new pane No. 2 in the former barracks. The shaft is installed in the DN 65 detachment in the north direction.

Connection pane No. 3 and No. 4 are scheduled for the installation of future drains to the thermal substations of existing buildings during their renovation. In pane No. 5, installs a condensed scolp, and the pane predicts a typed condensate bus. When performing the steam-operated connection for object “B”, the condensate drainage will be taken to the heat substation in a condensate relief vessel.

From pane No. 5 to the room of the heat substation is run steamwater DN 40.

Izvan prometnice parovod DN 150 se polože u betonski kanal svijetlih dimenzija 500 x 400 mm, a parovodi DN 65, DN 50 i DN 40 su položeni u betonski kanalu 400 x 300 mm.

The total length of the new junction DN 150 is 204 m and the connection is 292 m.

For the construction of steam water, seamless steel pipes NP 2.5 MPa, made of material Č.1212, according to HRN C.B5.221 with the test. Pipe arches are made of the same material as pipes, with dimensions according to HRN M.B6.821 for R = 1,5 d. As an insulating material, mineral wool in pillows, in aluminium sheet wraps, with the thermal conductivity coefficient of lamda = 0.047 W/m°K is selected.

Corrosion protection is provided by coating with two layers of temperature-resistant coating up to 250 C.
