Function and Description
Floating roof 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-resistant metal hoses installed without tension.
The upper scissor pipe is connected to the roof drain valve, 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.
Dimensions
Solutions are available from 3” to 8” for floating roof tanks with external floating roof
Material Selection
PROTEGO® floating roof drainage systems are designed and sized to suit the individual tank specifications and customer requirements. PROTEGO® floating roof drainage systems are designed for a long life in service. We use only carbon steel or stainless steel as the material of construction. For the carbon steel version the joint bearings are made of stainless steel.
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 systems are not required.
For stability reasons metal hose joints are made of steel or stainless steel.
Options upon request:
- Roof drain valve
