Floating Roof Drainage System
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.
