ATT Tank Floating Suction and Oil Skimmer Systems
The ATT TankFloating Suction Lines and Oil Skimmer Lineare internal piping assemblies that allows operators to withdrawal product from the upper levels of the medium stored in their storage tank.
The ATT Tank Floating Suction Lines and Oil Skimmer Lines are using rigid articulated pipe (having one or more swivel joints or swing joints) are designed to travel in a vertical plane and prevent damage to the floating roof and the suction line through its design range of travel. Our ATT Tank Floating Suction Lines and Oil Skimmer shall be designed so that the vertical plane is as close as possible to, and in no case greater than 10 degrees off a radial line from the tank centerline to the nozzle. Adjustments might be made to clear internal structures.
During the initial fill the internal floating roof should be checked to confirm that it travels freely to its full height. The high flotation level shall be evaluated for clearance and the floating suction (if existing) shall be compensated for the excess buoyancy that will be encountered during hydrostatic testing of the floating roof system.
During the first event of lowering the level from full height, particular attention shall be given to the floating suction to ensure proper operation.
The ATT Tank Floating Suction and Skimmer Lines are available in standard sizes from 3” up to 24”. All our joints will be delivered with a test certificate.
