Tanks Connected Tank Drain Data Sheet and we will provide installation drawings for you. The Tanks Connected  Drain System is easy to install in any tank. 


Each drain line requires just a 500mm wide corridor to operate in, between sump and shell nozzles. In tanks above 60m diameter, it is advisable for safety reasons, to fit more than one drain. This can easily be done with the Tanks Connected Drain System. 


As many as 5 lines have previously been fitted to one large crude oil storage tank. 

Tanks Connected Drain advantages over swivel joint drains: 

Conventional Swivel joint drains will eventually leak and require periodic maintenance. Tank cleaning costs are extremely expensive. 


Tanks Connected Drain joints will give a maintenance-free life of more than 15 years. Only 4 Tanks Connected Drain joints/lines are required. This makes a Tanks Connected Drain much cheaper, simpler, lighter and easier to install 


Tanks Connected Drain advantages over hose drains: All types of drain hoses have problems from time to time interfering with floating roof landing legs. This results in premature drain failure. Drain hoses can have problems with their own buoyancy, they must be very heavy to overcome their own displaced weight. 

Tanks Connected Drains will always remain within the same narrow operating corridor, and will never interfere with landing legs because of the fixed geometry of the Tanks Connected Drain system.
