There are many kinds of hoses used to transfer fluids such as hydraulic oil, water or steam. Braided wire Hoses are one type. This is where multiple layers of wire are criss-crossed in patches to increase strength.
Spiral wound hose reinforcement is also a common form of reinforcing hoses. This type of reinforcement is made by wrapping several spools wire around a tube while mandrels draw it through a machine.

A steel wire winding reinforced braided hose is a hose that is reinforced with high tensile wires which are crossed and woven over one another to strengthen the tube below. The crisscrossing nature of the wires gives them more tensile play than a spiral hose, which is why these types of hoses are more flexible than spiral hoses.
These hoses can withstand extremely high internal pressures, many thousands of impulse cycles and pressure surges. They can also withstand any pulsation waves in the system.
Spiral wound reinforcement is a common construction used in most hoses. This is made by twisting multiple spools wire around a tube while mandrels are drawn through the machine.
To prevent tension force gaps, the wire spools are tightly wrapped around the tube. The spools are made of high strength wire that is rated to withstand at least 30 MPa of pressure.
Wire is an easy material to make and is readily available in many tensile strengths. The optimum tensile strength depends on the alloying elements of the wire and the strain hardening method.
These three elements can be combined to make steel wire. * At least 0.30 percent of carbon is required for strain hardening. The higher the carbon content, the stronger the wire will be.
Installation of steel wire winding reinforced braided, hose
When working with steel wire winding reinforced braided hose, precautions should be taken to prevent potential problems. These precautions include proper bobbin and winding device settings, proper traverse dimensions and spacing, and reversal settings that ensure the correct wire is wound from flange to flange.
In addition to these, a hose should never be bent beyond the recommended Minimum Bend Radius (MBR). This increases the likelihood of damage and fatigue cracks appearing in the hose. This can also increase the likelihood of a hose breaking or braid bagging.
A high tensile strength wire is another consideration when using stainless steel wire. This will prevent a hose's lengthening at break and prolong its life.
A hose that has a higher tensile force than the wire used to construct it will be more resistant to vacuum and abrasion. It will also allow for better fluid delivery. Brookfield Wire supplies round steel wire to metal hose manufacturers to provide superior suction and delivery hoses in the most demanding environments.

Hydraulic hoses come in many construction types depending on the application and hydraulic fluid type. These include braided hoses and spiral wound hoses. Braided hoses are typically used in higher pressure applications, while spiral wound hoses are more common in very and extremely high pressure and high impulse applications.
In these high pressure and high impulse hydraulic hoses, it is important that the hose has minimal weight and maximum flexibility to handle the large internal working pressures required to support the heavy duty components within the hose. In addition, the hose needs to be capable of withstanding tens of thousands of pressure surge and relaxation cycles that can occur during service life.
One or more reinforcement layers consisting primarily of steel wire are used in hose structures. These constructions may be a braided wire construction, an all wire spiral construction or a wire spiral with a low tensile strength textile pick yarn braided through the wire spiral.
This invention combines the performance benefits of the spiral wound wire and braided wire constructions to create a hydraulic hose. It achieves this by having a hose that consists of an elastomeric tube, a braiding spiral sleeve surrounding the elastomeric tube having a first braid member and a second braid member under equal tension.
