High-temperature hydraulic hoses are indispensable components in many industrial fields, especially in high temperature, high pressure and corrosive environments, where they undertake the important task of transmitting hydraulic fluids. However, the service life of high-temperature hydraulic hoses depends not only on their manufacturing quality and actual use conditions, but also on the storage method. Improper storage may cause the hose to age, deform or be damaged, thus shortening its service life. This article will discuss in detail how to properly store high-temperature hydraulic hoses to maximize their service life.
1. The importance of high-temperature hydraulic hose storage
High-temperature hydraulic hoses are usually made of high-temperature resistant materials (such as fluororubber, silicone rubber or polytetrafluoroethylene), which have excellent heat and chemical resistance, but may still be affected by environmental factors during storage. For example, ultraviolet rays, moisture, extreme temperatures, mechanical pressure or chemical pollution may cause the performance of the hose to deteriorate. Therefore, scientific storage methods can not only protect the physical and chemical properties of the hose, but also ensure that it remains in the best condition during installation and use.
2. Basic principles for storing high-temperature hydraulic hoses
When storing high-temperature hydraulic hoses, the following basic principles need to be followed:
Avoid extreme environments: High-temperature hydraulic hoses should be stored in an environment with suitable temperature and humidity, and avoid exposure to extreme high temperatures, low temperatures or humid conditions.
Prevent mechanical damage: The hose should be kept away from squeezing, twisting or stretching during storage to avoid permanent deformation or damage.
Avoid chemical pollution: The storage area should be away from oils, solvents or other chemicals that may corrode the hose material.
Avoid ultraviolet radiation: Long-term exposure to sunlight will accelerate the aging of the hose material, so light-proof storage should be selected.
Keep clean: The storage environment should be kept clean to avoid dust, dirt or other impurities adhering to the surface of the hose.
3. Specific methods for storing high-temperature hydraulic hoses
Choose a suitable storage environment
High-temperature hydraulic hoses should be stored in a dry, well-ventilated indoor environment. The ideal storage temperature should be kept between 10°C and 25°C, and the relative humidity should not exceed 65%. Avoid storing hoses in open places or near heat sources (such as boilers, heaters).
Use special stands or shelves
Hoses should be stored flat or hung on special stands or shelves, and avoid stacking directly on the ground. If the hose is long, it is recommended to coil it into a ring with a larger diameter and secure it with a tie to prevent twisting or tangling. Be careful not to bend excessively when coiling to avoid damaging the hose structure.
Avoid contact with sharp objects
The storage area should be cleaned and ensure that there are no sharp objects or rough surfaces to avoid scratching the outer wall of the hose. If the hose has a metal joint, the joint part should be covered with a protective cover to prevent it from colliding with other objects.
Avoid chemicals
The storage area should be away from chemicals such as oils, solvents, acids, and alkalis. These substances may penetrate into the hose material and cause its performance to deteriorate. If there are chemicals in the storage environment, it is recommended to place the hose in a sealed container.
Store away from light
Ultraviolet rays are one of the main factors that cause hose aging. Therefore, high-temperature hydraulic hoses should be stored in a dark place or covered with an opaque cover (such as UV-proof cloth).
Regular inspection
Even if the hose is in storage, its appearance and performance should be checked regularly. The inspection contents include:
Whether there are cracks, bulges or deformations;
Whether the joint part is intact;
Whether there are signs of chemical contamination or moisture.
If any problems are found, the hose should be handled or replaced in time.
4. Precautions for long-term storage
For high-temperature hydraulic hoses that need to be stored for a long time, in addition to the above methods, the following points should be noted:
Keep the inside of the hose dry
Before storage, make sure that the inside of the hose is completely dry. If there is liquid remaining inside the hose, it may cause the material to swell or corrode. Compressed air can be used to blow the inside dry.
Use a dust cover
During long-term storage, it is recommended to wrap the hose with a dust cover or plastic bag to prevent dust and impurities from entering.
Avoid long-term pressure
The hose should avoid long-term pressure during storage, especially the joint part. Foam pads or soft materials can be used to support the hose to reduce pressure.
Turn it over regularly
For coiled hoses for storage, it is recommended to turn it over every once in a while (such as 3 months) to prevent local pressure or deformation.
5. Consequences of improper storage
If high-temperature hydraulic hoses are not stored properly, the following problems may occur:
Material aging: UV rays, high temperatures or chemicals can accelerate the aging of hose materials, making them hard, brittle, or even cracked.
Performance degradation: Deformed or damaged hoses may not be able to withstand high pressure or high temperature after installation, resulting in leakage or rupture.
Safety hazards: Damaged hoses may suddenly fail during use, causing equipment damage or personal injury.
The storage of high-temperature hydraulic hoses has an important impact on their service life. The service life of the hose can be significantly extended by choosing a suitable storage environment, using special brackets, avoiding chemical pollution and UV exposure, and regular inspections. In addition, for hoses that are stored for a long time, additional protective measures are required, such as keeping the interior dry, using dust covers, and turning over regularly.
Proper storage of high-temperature hydraulic hoses not only extends their service life, but also ensures that they perform at their best at critical moments. A good storage environment, reasonable storage methods, and regular maintenance inspections are all important measures to ensure the quality of the hose. Through the storage tips introduced in this article, I believe you can manage high-temperature hydraulic hoses more effectively, improve their use efficiency, reduce replacement costs, and provide guarantees for the safe operation of equipment.
