Top loading riser OSN-SVN

Top loading riser is construction of loosely joined pipelines with special equipment to barefoot and pressure tight fill petroleum product and other liquids in road and railway tanks.

Equipment consists of two fitting pipes and telescopic pipe is pulled down in tank. Fitting pipe №1 is connected with loading rack quit sweeps in a horizontal plane; fitting pipe №2 is connected with fitting pipe №1 sweeps in a horizontal and vertical planes. Telescopic pipe renders possible to meet State Mining and Safety Organization requirements to restrict free fall distance of HFL (highly-flammable liquid) fluent while loading. And riser may be equipped with pressure cup and special universal restrainer. Restrainer provides leakproof pressure cup fixing on tank any type of construction. Device equipped with indexing mechanism is prevented inadvertent tube rise if mounting on tank neck.
