You need to consider several factors to selecting the right composite hose for specific use. Here are the key aspects to take into account:
Chemical Compatibility
The hose must be compatible with the medium. For chemicals like sulfuric acid, a hose with resistance to strong acids is more better. For example, PTFE.
Inner Diameter
The inner diameter of the hose is determined by the flow rate requirements. Larger flow rates typically require larger inner diameters to maintain an appropriate velocity and minimize pressure losses.
Length
The length of the composite hose should be sufficient to reach between the required connection points. Besides, there should be some additional length to account for movement and installation flexibility. However, overly long hoses can increase pressure drop and cost.
Temperature Range
For high temperature mediums like steam, silicone hose is more better. While for extremely cold conditions, a hose with PU out layer is better.
Working Pressure
The hose should be able to handle the max pressure during operation. It’s crucial to choose a hose with a pressure rating higher than the working pressure. Because only this can ensure safety and reliability.
Outdoor or Indoor Use
An outdoor-use hose need to be resistant to UV radiation, weather and temperature variation. Indoor applications may have different requirements. Such as resistance to abrasion from equipment or foot traffic.
