Hydraulic Rubber Hoses Temperature:
Rubber hydraulic hoses are used in high pressure hydraulic systems for control and power supply. They are designed
to transfer hydraulic oil primarily. For other applications (e.g. for compressed gases) always contact Technical Department of
For water, water-based fluids and air, the maximum working temperature is +70°C.
For air over 17 bar, the external layer of the hose should be pinpricked and have additional protection.
Rubber hydraulic hoses are used for power transmission and control in hydraulic systems.
Due to its construction, hydraulic hoses can be divided into following categories:
Hydraulic Rubber Hoses Braid：
hoses with textile braid (one or two layers).
hose with one or two layers of steel wire braid (one, two and three layers).
hoses with spiral wire braid (four or six layers).
Hydraulic hoses are manufactured in imperial sizes and standardised. The most popular standards defining requirements for hoses are as follows: American SAE, German DIN, International ISO and European EN.
Apart from standardised hoses (according to above mentioned norms) our offer includes hoses with increased flexibility, higher working temperature, increased abrasion resistance of external layer or better chemical resistance.
Hydraulic Rubber Hoses Require：
For a proper choice of hydraulic hose to a particular application below mentioned aspects has to be taken into account:
working pressure and working conditions (static/dynamic),
medium and ambient temperature.
Hydraulic hoses designed for mining applications must fulfil additional requirements connected with explosives and fire conditions present in mines.
Hydraulic hoses assembled with the use of fittings crimped on crimping machines.
Hydraulic Rubber Hoses composition:
Rubber hydraulic hose is a common and essential component in a wide range of industrial and mobile machines. It acts as the plumbing that connects tanks, pumps, valves, cylinders, and other fluid-power components. Furthermore, hose is easy to route and install, and it absorbs vibration and dampens noise. Hose assemblies, which are hoses with couplings attached to the ends, are relatively simple to construct. Hose can last for hundreds of thousands of pressure cycles if properly specified and not overly abused.
Hydraulic hoses consist of an inner tube, one or more layers of reinforcement, and an outer cover. Each constituent should be selected with the intended application in mind. Typical operating and performance parameters include the size, temperature, fluid type, pressure-holding capacity and environment, to name a few.
The inner tube contains the fluid and keeps it from leaking to the outside. The type of hydraulic fluid generally dictates the tube material. Usually it is nitrile or synthetic rubber for petroleum-based hydraulic oil. But alternatives like Viton or Teflon are used with synthetic fluids like phosphate ester.
The reinforcement layer is shielded by the cover. Resistance to attack from outside influences such as chemicals, salt water, steam, UV radiation, and ozone is one factor to consider when selecting a cover material. Among the most common cover materials are nitrile, neoprene, and PVC.
Bend-radius,friction and abrasion can be issues when a hose rubs against adjacent structures or other hoses. Because if the cover wears away, exposing the reinforcement to mechanical and chemical attack, the hose will frequently fail quickly. To help prevent harm, a number of manufacturers offer tough, abrasion-resistant covers.
We offer a range of hydraulic rubber hoses for many different applications, users must consider the system pressures, temperatures, weight, and flexibility required. Users must consider the critical nature of the application, downtime, and peace of mind when selecting a hydraulic rubber hose and coupling supplier; all hydraulic hoses are NOT made the same even though they have the same SAE rating. Higher end brand hoses will typically be made to higher tolerances, better compounds, better resistance to various factors, added durability, enhanced engineering methods, and additional assurance of a proven system. With leading, innovative manufacturers, the market has seen improvements in hose design - such as more flexibility, lighter weight, higher temperature compounds, tougher covers, less manufacturing defects, and overall more durable products.
In various areas of building, construction, mining, agriculture, transportation, food and other markets, where hydraulic and industrial hose is required our quality products meets and exceeds all industry standards.
