The USN-150 device is designed for bottom discharge of oil and oil products from railway tanks and is a swivel pipeline with a support pipe and a connecting head. Double-row hinges ensure ease of movement without distortion during long-term operation. Replacing the seals does not require disassembling the hinges.
The grips rotate relative to the connecting head, which allows them to be installed in any convenient place on the tank drain device.
The hinged design of the grippers and the special form of the connection head seal ensure a reliable, hermetic connection of the device to the skewed tank drain device.
