Drainage System for Floating Roof Tanks
Floating roof Floating roof A floating roof is the roof of a tank that is fitted with floating chambers (pontoons) and lies on top of the liquid. tanks require a drainage system that automatically drains the accumulating rainwater from the floating roof. PROTEGO® SE/K is a single-scissor pipe system that works with sturdy shackle joints. The water is drained by pressure Pressure (gauge pressure) Pressure for which the value is equal to the algebraic difference between the absolute pressure and the atmospheric pressure. -resistant metal hoses installed without tension. The upper scissor pipe is connected to the roof drain valve Roof drain valve A roof drain valve is mounted on floating-roof tanks and allows controlled draining of collected rain water into the sewage system via a floating roof drainage system. , and the lower scissor pipe is connected to the bottom pipe. The water is drained from the tank through the drainage system via the opened roof drain valve.
"Made in Germany"
PROTEGO® Floating Roof Drainage Systems are „Made in Germany“ and will provide many years of trouble free tank operation.Selection and Design
PROTEGO® Floating Roof Drainage Systems offer experienced technology for a complete solution for the end-user.This includes easy installation and assembly and full documentation with an arrangement drawing showing the Floating Roof Drainage System placed in the tank with regards to all internals.
The flexibility of the metal hose is realized by the shakle-boltedjoint. Forces that may occur due to torsion or uneven movements of the floating roof are absorbed through design and arrangement of the joints and thus have no negative effects on the system or metal hoses. The water is drained by metal hoses that are directly connected to the scissor pipes. The drain water does not pass through the actual joints and therefore sealing elements as used for common swivel joint Swivel joint Part of a swing pipe system. systems are not required.
For stability reasons metal hose joints are made of steel or stainless steel.
Options upon request:
- Roof drain valve
- Bottom pipe
