Raw water intakes are best fitted with which type of hose?

Raw water intakes are best fitted with wire reinforced hose due to its structural integrity and resistance to collapse when subjected to vacuum conditions. This type of hose is designed to withstand the pressure variations that occur in raw water systems, particularly when a pump is drawing water in.

The wire reinforcement provides added strength and support, making it less likely to deform or pinch under suction, which is essential to maintain proper water flow and keep the system functioning efficiently. Additionally, wire reinforced hoses are typically made from materials that can withstand the corrosive effects of water, offering durability and longevity in marine environments where exposure to saltwater and other elements can be a concern.

Other types of hoses, such as clear PVC, while useful in certain applications, do not provide the same level of reinforcement against vacuum collapse. Braided vinyl hoses, while flexible and useful in many situations, also lack the structural reinforcement needed for high-pressure water intake systems. Correlated bilge pump hoses may not be suitable for raw water intake purposes either, as they are often optimized for discharge applications rather than intake suction. Thus, the wire reinforced hose is the most suitable choice for ensuring reliability and efficiency in raw water intake systems on vessels.
