Roof Drain

Roof drain composite hoses are specialized flexible hoses designed for effectively draining rainwater and other liquids from floating rooftops, particularly in industrial and commercial settings. These hoses are composed of multiple layers of different materials, each chosen for its specific properties that contribute to the overall functionality and durability of the hose. Proper installation, maintenance, and periodic inspections are essential to ensure the hoses continue to function optimally and prevent any potential leaks or drainage issues.

Compliance : Roof Drain hoses are manufactured in accordance to EN 13765 / 2018 Type 3

Applications

Roof Drainage Systems: The primary application of Roof drain composite hoses is in floating roof drainage systems. These hoses are used to channel rainwater and other liquids from rooftops to designated drainage areas. They provide a flexible and efficient way to transport water away from the building, helping to prevent water damage and leaks.

Rainwater Harvesting: In systems that collect rainwater for reuse, Roofdrain composite hoses can be used to direct rainwater from the rooftop to storage tanks or reservoirs. These hoses need to be durable and resistant to UV exposure and other weather conditions to ensure reliable operation.

Emergency Drainage: In the event of heavy rainfall or other emergency situations, Roof drain composite hoses can be deployed to quickly drain excess water from rooftops and prevent flooding.

Temporary Drainage: During construction or renovation projects, temporary Roof drain composite hoses can be used to direct water away from work areas, preventing water damage to building materials and providing a safer working environment.

Safety Standards

Rigorous Safety Testing

COMPOHOSE assemblies undergo comprehensive testing, conducted at 1.5 times the rated Working Pressure (W.P). This stringent testing adheres to the EN 13765 standard, ensuring a paramount level of safety and reliability.

Provision of Manufacturer's Test Certificate

With each supply of COMPOHOSE composite hose assemblies, a Manufacturer's Test Certificate is included. This certificate serves as a confirmation of the product's quality and compliance with safety standards, providing added assurance to users.

Clear Burst Pressure Specification

The burst pressure of the composite hose is explicitly indicated for ambient temperature conditions. This vital information enhances safety awareness and empowers users to operate within secure pressure limits.

Effective Electrical Continuity

The composite hose's electrical continuity is assured through the integration of two bonded wires connected to the end fitting. This innovative design promotes the dissipation of accumulated electrical charges, mitigating the risk of static flashes and associated hazards.
