Characteristics of Industrial Hoses

Pressure: To be able to describe an industrial hose and determine the intended application, the specification of relative pressure values at a temperature of 20 degree Celsius is important. The operating pressure thereby represents the continuous working pressure whereas the bursting pressure is the maximum pressure from which point the industrial hose begins to leak. Higher temperatures and a pulsating flow of the medium reduce the maximum compressive strength.
Temperature: Both the temperature of the medium flowing through the hose and the ambient temperature affect the aging process of industrial hoses. Rubber compositions appropriate for the intended use of the hose must therefore be chosen.
Bending radius: Contrary to pipes, industrial hoses offer the advantage of flexibility. Industrial hoses therefore have a specific mandatory minimum bending radius, which must be achieved for a hose under operating pressure. The minimum and maximum bending radius depends on the inside diameter, the materials used, the construction of the reinforcements, the helix and the wall thickness.
Inside diameter: The inside diameter is an important identifier to characterising industrial hoses. The inside diameter determines the volume flow rate depending on the flow velocity of the medium in the hose.
Outside diameter: Together with the inside diameter, the outside diameter also determines compatibility with the desired gate valves and hose couplings.
