Industrial Hydraulic Hose Manufacturer in Ahmedabad
Essem Works Pvt. Ltd. manufactures premium industrial hydraulic hoses specifically designed to deliver hydraulic fluid to hydraulic components, actuators, valves, etc. Every hose has a finite life depending upon the service conditions to which it is exposed – If a hose is subjected to conditions more severe than recommended limits then its life will be significantly reduced. Variable factors. which can affect the actual service life, include:
- 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 minimum bursting pressure.
- MINIMUM BURST PRESSURE: - Burst pressures are reference values during in-house destructive tests, which are used to determine the strength of the hose and to establish design safety factors.
- PRESSURE SURGES: - Almost all fluid system develops pressure surges which may exceed relief valve settings. Exposing the hose to surge pressures 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 a hose with a higher rated working pressure.
- TEMPERATURE RANGE: - Hose should not be exposed to internal or external temperatures exceeding the recommended limits. as high heat conditions can cause an adverse effect on the hose by degrading the Elastomer and reducing fitting retention. Continuous use at near maximum temperature can also cause hose damage while continuous use at maximum temperatures together with maximum pressures should be avoided.
- FLUID COMPATIBILITY: - The hose assembly tube, cover, reinforcement and connections 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, pressure drop, heat generation and tube damage.
- HOSE LENGTH AND ROUTING: - Select the correct length of hose taking into account vibrations, flexing and hose assembly routing. To protect and guide hose to minimize risk of damage use clamps, bends, adapters, protective sleeves wherever required to prevent excessive flexing, pulling, kinking, whipping and contracting or corrosives.
- MINIMUM BEND RADIUS: - Do not bend of flex hose beyond the specified parameter as this would put excessive stress on the reinforcement and severely reduce the ability of the hose withstand pressure.
- HOSE ASSEMEMBLY INSEPECTION: - 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, e.g. ultraviolet light, 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.
