APPLICATION FACTORS OF HOSE

A.When choosing hose,please pay attention to the followings:

1.Working Environment: Working temperature,weather and the connection with other materials.

2.Conveyable Matter: Liquid,gases,solid or the mixture of above materials.

3.Convey Ways: Delivery material under the pressure,delivery and suction under vacuum.

4.Working Condition: The pressure and temperature for conveying matter,use frequency,impulse and movements.

5.Installation: Bending,vibration of the system,the risk of damaged caused by hitting and friction,application of the right connecting mode.

B.There is a limited life for hose assembly;please pay attention that the followings would reduce the hose useful life:

1.Make the bend radius smaller than the min bend radius.

2.Twisting,stretching,weld line,squeeze or corrode the hose.

3.To be used at exceeded max temperature or lower the min temperature.

4.To be used under the impluse pressure exceeding the max working pressure(the impulse pressure means the rapid rise of pressure).

5.The quality of fitting is not up to the standard and assembling is not well.

C.Requirements for using hose:

1.The pressure(including the impulse pressure) filled in the hose must not be exceeded the max working pressure.

2.Hose can not be used under the temperature not stipulated or suggested including the conveyable matter's temperature and environment temperature.

3.Hose can not be used under the bend radius that is smaller than min bend radius stipuated or suggested,or it will block the matter passing,and reduce the hose useful life.The hose should be precent from twisting or warping around the connection part,because the bending for this part will damage the reinforcement,as a result,the hose will be damaged quickly.

4.The hose can not be used when it is twisted.

5.The edge of hose fitting should be smooth;the size of mandril sleeve or other accessory must be in confirmed.Less or more control of assembling power will also damage the assembly.
