Internal Floating Roof Tanks; Fabrication,Construction

Internal floating roof / floating deck tanks are storage tanks mainly used to contain petroleum products.The design minimizes risk of combustion and contamination of valuable and volatile petroleum products,especially during the filling and emptying cycles of the storage tank.The floating roof sits directly on top of the stored product at Internal Floating Roof Storage Tank VS External Floating Floating roof is the core component of floating roof storage tank,which is divided into two types external floating roof and internal floating roof.Because the flexible floating roof deck can float up and down to close to the liquid level,gas space above the liquid level can be greatly reduced,thereby greatly reducing the evaporation Foam Requirements for Internal Floating Roof Tanks -Jan 23,2004 Design and construction requirements for floating roof tanks#0183;We have an atmospheric storage tank storing Heavy Naptha that was converted from a cone roof to an internal floating roof a while back.It has hard pipe up to the top of the tank (where you can hook up foam in case of a fire) that leads into a box with this coiled up hose in it.
