Settings drain-naliva USN-150 (175, 200) and steam heating USN-150Pp (-175Pp, -200Pp) GOST 18194 are designed to drain or light oil through the drain unit of railway tanks. Details of installation of drain-loading in contact with the pipe rail car, are intrinsically safe.
Position count hinges made of two variants with four hinges (Fig. 1,2) and with five joints (Fig. 3).
Plants with five hinges and steam heating (USN-150/5Pp, -175/5Pp, -200/5Pp) can compensate for possible deviations of the axis of the tank drain device from the vertical position, which significantly improves the tightness of the joint installation of USN with a drain tank device.
Allowed:
a) the application for discharge or loading of other liquids, non-corrosive to steel, and oil and petrol resistant rubber;
b) production installation of steel 12X18H10T.
