3+1 Articulated Type Roof Drain System

Articulated type drain systems are made up of steel tubes and mechanical joints (flexible oscillating joints or swivel joints), designed to withstand the forces that may be causing various operating conditions. The system typically incorporates high-strength joints, but several alternatives are available to meet customer requirements.

Flexible Swing Joint

WB's patented twin access seal drain system can be used as a rubber hose movement type on storage tank roofs.

Check Valve

Unique design of the WB float check valve to prevent possible overflow of the drain line.

Swivel Joint

The fully sealed WB swing joint is specially designed for the service of submerged liquids, such as the articulated pipe drain system, oil skimmers and floating suction lines.

Hose Type Drain System

This system allows for the fastest drainage of water through the hose, allowing maximum drainage of rainwater in the shortest possible time. The flexible and easy-to-handle hose is used inside the storage tanks, to drain the water on the floating roofs. Specifically designed to ensure the repeated same hose placement pattern to prevent collision between the tank's internal components (floating roof leg, leg guard, etc.)

To achieve the above, each assembly is inspected, measured and tested from start to finish, to ensure the highest product quality to every customer worldwide.
