What is a hydraulic hose pipe?
A hydraulic hose pipe conveys hydraulic fluid to or between hydraulic components. Components include valves, tools, and actuators. Hydraulic hose pipe is usually flexible and reinforced. Hose is often made up of several layers of reinforcement. ... The hoses are flexible enough to bend around corners and fit in tight spaces. Hydraulic hose pipe is used in a variety of industrial hydraulic systems. Dimensions, performance specifications, construction options, and features are important parameters to consider when searching for hydraulic hose pipe.
Important dimensions for the selection of hydraulic hose pipe include the inside diameter, outside diameter, and minimum bend radius. Hydraulic hose pipe sizes are denoted by the inside and outside diameter of the hose. The inside diameter refers to the inside of the hose or liner. The outside diameter is often a nominal specification for hoses of corrugated or pleated construction. Minimum bend radius is based on a combination of acceptable hose cross-section deformation and mechanical bending limit of any reinforcement.
Construction options for hydraulic hose pipe include reinforced, coiled, corrugated, or convoluted. Reinforced hose is constructed with some element of reinforcement—styles include textile braid, wire braid, wire helix, and other designs in many ply or layer configurations. Coiled hose is coiled for flexibility and elasticity. This feature often makes it expandable and easy to store. Corrugated hose contains corrugations, pleats, or spiral convolutions to increase flexibility and capacity for compression and elongation. Multi-element hydraulic hoses are constructed of more than one hose formed or adhered together in a flat, ribbon, or bundled configuration. Additional features to consider include integral end connections, anti-static, lay flat, crush-proof, flame-resistant, and explosion-proof.
In addition, material considerations include the type of fluid being conveyed and its concentration as well as substances that may attack the hose cover. Hose selection must ensure compatibility if it is to convey special oils or chemicals. The same holds for hose exposed to harsh environments. Substances such as UV light, ozone, saltwater, chemicals, and pollutants can cause degradation and premature failure. For in-depth fluid compatibility data, consult the manufacturer.
