HOSE CONCRETE CONVEYING HOSE HIGH PRESSURE DRY AND WET CEMENT

Working Pressure

The fluid system pressure including surge pressure should not exceed the rated working pressure of the hose-usually one fourth of the hose maximum bursting pressure.

Minimum Burst Pressure

Burst pressure are reference value during in-hose destructive tests, which are used to determine the strength of the hose and to establish design safety factors.

Pressure Surges

Almost all fluid systems develop pressure surges which may exceed relief value settings. Exposing the hose to surge pressure above the rated working pressure will shorten hose life and must be considered in selecting the proper hose. A surge which may not be indicated on many commonly used pressure gauges, can be measured using specialized electronic equipment. The safety factor in systems where severe pressure surges occur can be increased by selecting the hose with a higher rated working pressure.

Temperature

Hose should not be exposed to internal or external temperatures exceeding the resommended limits, as high heat conditions can cause and adverse effect on the hose by degrading the Elastomer and reducing the fitting retention. Continuous use at near maximum temperatures can also cause hose damage whilst continuous use at maximum temeperatures together with maximum pressure should be avoided.

Fluid Compatibility

The hose assembly (tube, cover, reinforcement and coupling) must be fluid compatible.

Hose Size

The hose size must be capable of handling the required flow volume. Using the smaller than required diameter of hose for a given volume of flow would result in excessive fluid turbulence, pressuredrop, heat generation and tube damage.

Hose Length and Routing

Select the correct length of hose taking into account vibrations, flexing and hose assembly routing. Use Clamp, bends, adapters, protective sleeves to protect and guide hose to minimize risk of damage wherever required to prevent excessive flexing, pulling, kinking, whipping, and contact to corrosives.

Minimum Bend Radius

Do not bend or flex hose beyond the specified parameter as this would put excessive stress on the reinforcement and severly reduce the ability of the hose to withstand the pressure.


Hose Assembly Inspection

All hose assemblies in service should be frequently checked for leakage, kinking, corrosion, abrasion or any other signs of wear and damage. Any hose assembly worn or damaged must be removed from service and replaced immediately.


Environment

Hydraulic hoses are more resistant to certain degradation, eg., Ultravioletlight, Ozone and many hydraulic fluids. Nevertheless due regards must be given to the working environment and the selection of hose best suited to operating conditions.


Safety Protections

Improper selection, installation or maintance of hose may result in premature failures, property damage or bodily injury.
