Roof Drain Systems for External Floating Roof Tanks. There are three types of roof drain systems for External Floating Roof Tanks:- Flexible Hose - This has been an industry standard for many years as a cost effective drain system. It is essentially a composite hose from a connection on the roof sump to a shell nozzle. Installation and operation requires care to ensure that the hose does not become entangled in the roof legs and tank internals. Articulated Roof Drain Systems with swivel joints – an improvement over the Flexible Hose Drain System, designed using rigid pipe sections to connect the sump to shell nozzle with a continuous slope to eliminate any risk of water retention in the drain system. Articulated Roof Drain Systems with flexible joints - Similar to the above but instead of swivel joints being used this drain system uses a L&M TankServ Flexi - Joint © providing a much more reliable and significantly more cost effective Roof Drain System.
