about Rubber Hydraulic Hose & Supplies and ID and Working Conditions and Size and Categories and Standardised

Sinopulse 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.
These flexible rubber hoses maintain their strength by using a reinforcement layer made from high tensile steel wire. An outer layer of synthetic rubber makes the hose resistant to oils, abrasion and weather exposure.
You can build your own replacement hoses by combining bulk hydraulic hoses and attachments with our braided hose crimp fittings.

Rubber Hydraulic Hose Categories

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).

Rubber Hydraulic Hose Standardised

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.

Rubber Hydraulic Hose ID
1、Inner diameter (I.D.) is the span of the empty space in a circular hose cross-section that affects the flow velocity of the fluid within the hose. A hose with an oversized I.D. will result in sluggish system performance, while an undersized I.D. can cause excessive pressure drops, leaks, and system damage.
2、The length of the hydraulic hose defines its maximum reach between end-points. Increasing length can also increase the pressure drop in the system because hose length is a function of head loss due to friction.
3、Outer diameter (O.D.) measures the entire span of the hose cross-section, including the tube, reinforcement, and cover. The difference between the O.D. and I.D. is the thickness of the hose wall. Outer diameter is important for sizing industrial hose to appropriate fittings and system components.

Rubber Hydraulic Hose Working Conditions
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.

Rubber Hydraulic Hose Size
Starting with size, so this is probably the most critical of the factors when it comes to choosing your hydraulic hose. If you don’t get this right, so much can go wrong in your hydraulic system.
So for example, long length lead to increased energy required to move fluid. So if you have an undersized hose, you’re spending more energy trying to push fluid through the hose than you are energy moving your load. 
So hydraulic systems move loads through force that has to be transmitted through that hose. 
So if you need to conserve energy moving fluid, so you have the least amount of pressure drop possible, that allows most of that energy to be used to move your load.
