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.
