Rainwater draining from external floating roofs is of great importance to secure integrity of the floating roof. CTS offers several types of reliable roof drain systems for external floating roofs. These drain systems include conventional pipe drain systems, roof hose drains, flexible pipe drains with a repeatable lay pattern and a combination of both a hose and a rigid pipe system in our Drainmaster designed system. Some of these systems can be designed to deliver fire-fighting foam to a floating roof tank as well.
