Use a rubber hose storage

This specification reference standard: GB / T9576-2001 GB / T9577-2001 ISO 8331-1991

Hose storage:

1) Shelf life: identity hose timespan, FIFO. Shelf life as short as possible, the maximum does not exceed 24 months, and to be checked prior to use.

2) Temperature: Try to keep between 0 ~ 35 ℃ storage temperature in Celsius. Otherwise it will accelerate the aging of the hose.

3) Humidity: the best relative humidity ≤65%.

4) Light: Keep away from sunlight and strong artificial light source. Warehouse blackout dark glass windows should be used, to avoid light outside environment.

5) Ozone: Ozone will accelerate the aging of rubber tubing, can not have the equipment to produce ozone stored inside the warehouse. Such as mercury vapor lamps, high-voltage equipment, operation of the motor.

6) Storage Environment: NO contact with solvents, oil, acid and alkali, disinfectants. Not be exposed to steam.

7) stacking method: the coiled hose should lie flat with the principle of stacking height so that the bottom of the product should not be deformed prevail. Avoid contact with sharp surfaces.

8) Handling: When handling sharp and not on the rough surface drag, not subjected to flexing and flattening.

Hose:

1) Pressure: strictly limit the use of the design work under pressure (including shock pressure), in order to avoid accidental hose may burst danger!

2) Temperature: The temperature of the circulating medium temperature hose and its working environment must not exceed the manufacturer's range of design requirements!

3) medium transport: Use only in a predetermined design or purpose other fluids or fluid delivery within range of purposes, outside the scope of transportation design, manufacturers should consult!

4) Dangerous Goods: When transporting potentially dangerous, such as toxic, corrosive, explosive or flammable materials, precautions should be taken in order to leak or overflow due to the impact to a minimum.
Do not hose when not in use to keep in a state filled with a transmission medium.

5) Use of the environment: Do not use in an environment other than their intended purpose. Such as the applicability of the environment have questions, or experiencing unusual or variable conditions, should consult the manufacturer.

6) bending radius: Hoses can not be used in less than the manufacturer specified radius bend, because it might hinder the transmission fluid and damage the hose;
To avoid bending occurs near joints, otherwise it will strengthen fatigue hose, the hose leading to premature aging.

7) torsional stress: it can use reasonable bend, but should not be designed to reverse the state of use.

8) Tensile stress: Hose only in the design and manufacture of special conditions allowed withstand tensile stress within the specified range, otherwise it will damage the hose.

Connector assembly:

1) joints should be no sharp edges. Hose fittings suitable interference fit within the hole, the outer diameter of the sleeve and hose appropriate clearance fit.

2) withhold the pressure and hose clamps torque loads should be controlled. Because excessive pressure can cause the hose damage, insufficient pressure easy to loose.

3) When the assembly can be used with water or a neutral non-corrosive lubricant. Such as soap, detergent and other kitchen. Prohibit the use of solvents containing grease or lubricants do.

4) tube assemblies at a static test pressure hydraulic test specified no loose, no leakage generally 1.2 to 1.5 times the working pressure.

5) in a fixed installation, the hose and assembly should be supported as much as possible or holding fixed.

6) must ensure that the normal movement of the hose under pressure: the expansion, the change in length, when the clamping device is not limited distortion.

Inspection, maintenance:

1) regularly check the hose, the focus should be noted that the joint connecting parts, bent parts, hose if there are caused by the aging hardening and cracking.

2) especially in the harsh environment, abnormal operation or accident conditions.

3) When the hose has the following defects occur, you should immediately discontinue use and replace.

4) the appearance of cracks, local deformation, fizzy.

Expansion beyond the normal 5) pressure.

6) perforation, rip, tear, enhancement layer is exposed and the like.
