Safety Guide For Hose Assemblies

There are many factors which can affect the usage condition of hose assembly, use the hose assembly andhose fittings in acorrect way can ensure its reliability and economical efficiency. These factors are as follows:

1,Hose Dimension

The selection of hose inside diameter must be correctly made. lfthe hose inside diameter is too small, it willspeed up the medium in the pipe-line，heated the system, lower the efficiency and produce excessive pressuredrop which will affect the whole system's capability. lf it will fix with hose clamp or cross the steel board, theoutside diameter of hose should be pay more attention.

2, Working Pressure

The dynamic working pressure in this catalog refers to the allowable maximum pressure in condition ofcontinuously working.According to the safety modulusof hydraulic hose ruled by international standard, werecommend that the working pressure is one quarter of the minimum blast Pressures.

3, Impact Pressure & Fatigue Life-span

After determining the maximum system pressure for a hydraulic system, hose selection can be made.For thehydraulicsystem's pressure always be dynamic, there often appears an impact pressure, the maximum impactpressure is much higher than the maximum system pressure.To be luckily, there is an over fallvalve in everyhydraulic system, so high impact pressure cannot affectthe fatigue life-span seriously.As for hydraulic systemwhose impact pressure appears very frequently, we advise you choose the special hydraulic hose which is ableto endure the high impact Ptessure.

4, Temperature Range

User must ensure that the temperature is in an allowable range of hose, if exceeding this range, the life-spanof hose willbe shorten, and the capacity to endure pressure will get down.If the working condition temperaturekeep too high or too low in a long time, we advice you use the hose spring guard.

5, Chemical Compatibility

lf use special hydraulic medium, user should ensure the material of hose inner side and cover, the hose fitingsand O-ring can compatible with the special hydraulic medium.

6, Bending Radius

Pay more attention to its minimum bending radius when install the hose assembly, if the bending radius issmaller than the minimum one, the capacity of enduring pressure will get down and the life-span of hose will beshortened.

7,Friction

We advised you use a spring guard if the hose assembly is always in the condition oftouching and makingfriction with hard object.Any technicalquestion about Stronger Hydraulic hose assembly, welcome to inquire!
