Self-supporting cone roof API Std 650 insulated tanks

Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API Std 650 insulated tanks External floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API Std 650 insulated tanks external floating roof tank.

In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 insulated tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 insulated tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.

Proof Tests for Establishing Allowable Working PressuresBecause pressures in liquid storage tanks built according to these rules vary quite markedly from the tops to the bottoms of the tanks, proof testing of these tanks presents problems not usually encountered in the construction of unfired pressure vessels–especially where the API Std 650 insulated tanks parts under investigation are located near the bottoms of the tanks. The principal difficulty is devising a test or series of tests that will reliably establish the working pressure that can be permitted on the part of the unproven design without, at the same time, imposing hazardous conditions on other parts located at higher levels in the tank.

We can process the steel materials according to your drawing. Or if you can not make drawing, please send us API Std 650 insulated tanks specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.
