WATER DRAIN FOR RESERVOIR FLOATING ROOFS

摘要

FIELD: oil producing industry. SUBSTANCE: device intended for draining water from floating roofs of reservoirs has drain holes with connecting branch pipes on floating roof and on reservoir wall. Drain holes are connected by flexible metal pipeline made of stainless steel and provided with flexible cable connected to middle part of pipeline and to top of reservoir wall through holes in roof. Flexible cable is connected to pulling device. To provide lifting of middle part of pipeline in synchronism with floating roof, flexible cable is connected also to lower zone of flexible metal pipeline with excess of length of this section of pipeline relative to length of the same section of cable. EFFECT: enhanced draining of water from reservoir roof. 2 dwg øøø1
