If the hydraulic hose is used for a long time or improperly stored, some damage will occur, which may be oil leakage, surface blistering or surface cracking. We need to analyze different situations in detail, and we need to be more cautious about important parts. How to deal with the cracks of the hose in cold weather?

In a relatively cold winter environment, cracks on the outer surface of the rubber hose can cause the rubber hose to twist. If you find cracks on the outer surface of the rubber hose, you should pay attention to whether the rubber hose appears to be cracked, and decide whether to replace the rubber hose immediately.

The bearing capacity of the hose depends on the steel wire reinforcement layer, which is the skeleton of the hose, usually braided and surrounded by steel wires. Most of the high pressure and ultra high pressure are braided by multiple layers of steel wire and surround the frame. Low-pressure hose is woven from cotton and hemp instead of steel wire, and is generally used for low-pressure oil return pipelines. Temperature has a great influence on rubber hoses. Therefore, do not move the hose or disassemble and repair the hydraulic system at will in a cold environment to ensure the safety of the hydraulic hose. It should be done indoors when necessary. If you need to work for a long time in a cold environment, please replace the anti-icing hose.

Regardless of whether the outer rubber layer of the hydraulic hose is damaged or the inner and outer surfaces are defective, we need to handle it carefully to avoid minor problems causing major troubles. If the hose has passed its service life, we need to replace it in time. Don't regret it, and don't bury potential safety hazards in order to save money, endangering our personal safety.
