A wire braided hose consists of crossing and woven high tensile steel wires overlapping one another to reinforce the tube below. Wire braiding machines perform a complex task of winding the wire intricately around the tube, like dancers around a horizontal maypole. The overlapping nature of braided wire not only increases burst resistance to the tube but also allows flexibility between the braids. The crisscrossing braided wire has more tensile play than a spiral hose, resulting in tighter bend radius and overall flexibility.
A spiral wound hose consists of two or more sets of helically wrapped high-tensile wire that exhibits exemplary strength, making the hose very strong but also very rigid. The resistance to pressure spikes is exceptionally high, especially compared to a braided hose. However, the bend radius suffers, and spiral wound hose is highly resistant to bending. This effect is especially pronounced with 4- or 6-wire hoses, which are required from many large diameter, high-pressure applications.
