If during the gas network with loops projecting are forecasted that some of pipes are crossing each other without connecting, this sort of network became rather spatial, and such as are requiring initiation of additional corrections. According to Hardy-Cross calculation of classical two-dimensional network with loops (allocate in one flat) are existing two correction of flow. First correction is correlated to matched loop (contour), while the second correction are brought from adjoining loops (contours) whit which are existed joint pipes. The pipes common for three or more contours are existed at spatial gas distribution networks with loops are which, so here are inducted corrections of third or higher order.
