Sometimes we take basic information for granted in the fluid power business. The quest for knowledge begins with a grasp of the fundamentals, and there’s no greater lesson than understanding the distinctions between two fundamental hydraulic hose construction types.
The distinction between wire braid and spiral wound hydraulic hose is a frequently asked question. After all, not every person begins their career as a hydraulic hose assembly and repair expert. Both wire braid and spiral-wound wire have the same function, albeit with minor differences.
Wire braided hose
A wire braided hose is made out of overlapping and woven high-tensile steel wires that are reinforced by the tube beneath. Overlapping braided wire increases burst resistance for the tube while also allowing for greater flexibility between the strands. The crisscrossed braided wire has greater tensile play than a spiral hose, resulting in tighter bend radius and overall flexibility.
Spiral wound hose
A spiral wound hose is made up of two or more sets of helically wrapped high-tensile wire that has exceptional strength, resulting in a very durable but also rigid hose. The resistance to pressure spikes is particularly remarkable when compared to a braided hose. However, the bend radius is diminished, and spiral-wound hose is highly resistant to bending. This impact is particularly apparent with 4- or 6-wire hoses utilized in many big diameter, high-pressure applications due to their requirement.
The type of hose you choose will be determined by the demands of your application, but technological progress is reducing the strength of braided hose while simultaneously improving the flexibility of spiral wound hose. Because materials and manufacturing improvements are so rapid in the hose industry, both construction types should improve as a result.
