When Wire Stretch Hose develops air or liquid leakage during operation, it generally indicates a problem with the hose body, connection points, or sealing components. Leakage can reduce conveying efficiency and destabilize equipment operation. If the hose carries flammable, toxic, corrosive, or high-temperature media, leakage may also create additional safety risks. Therefore, the relevant operation should be stopped promptly, and the problem should be investigated in accordance with the equipment's safety procedures.
Cracks or physical damage to the hose body are common causes of leakage. During prolonged use, repeated bending, stretching, friction, compression, and external impacts may gradually cause surface cracks, localized thinning, or holes. If the damage extends deeper into the hose wall, the conveyed gas or liquid may escape through the affected area. When the hose conveys media containing solid particles, prolonged abrasion against the inner wall may also accelerate material wear. During routine inspections, pay particular attention to sections that are frequently bent or moved and areas that come into contact with equipment. Identifying damage early can help prevent leakage.
Loose connections may also cause air or liquid leakage. Wire Stretch Hose is generally connected to equipment or other pipelines using suitable fittings. If the connections are not secured properly during installation, are exposed to continuous vibration, or are repeatedly affected by hose movement, they may gradually loosen and lose their sealing effectiveness. Damaged connection components, deformation, or poor fit may also allow the conveyed medium to escape at the interface. When leakage occurs, inspect the connections for tightness, check the condition of the fittings, and verify that the installation complies with the product and equipment requirements.
Aging or damaged sealing components are another possible cause. Some connection structures use sealing rings or other sealing elements to prevent leakage at the joints. Over time, these components may lose elasticity due to temperature changes, chemical exposure, compression, or natural aging, reducing their ability to maintain a reliable seal. Improper installation may also cause a seal to become misaligned, damaged, or deformed. Inspect the sealing components according to the connection design and replace them when necessary. Repeatedly tightening the fittings is not always an effective solution.
Incompatibility between the hose material and the conveyed medium may also result in leakage. If the medium causes corrosion, swelling, or other adverse reactions, the hose may gradually soften, harden, crack, or lose its structural integrity. Certain cleaning agents, solvents, and industrial chemicals can also affect hose materials. If leakage begins after the conveyed medium has changed, reassess the compatibility of the hose material with the new medium and verify that the operating temperature and pressure remain within the product's permitted limits.
To reduce the likelihood of leakage, regularly inspect the hose surface, connections, and seals. Avoid excessive bending, continuous friction, and improper handling, and ensure that the product is suitable for the conveyed medium and operating environment. By identifying abnormalities promptly, determining their causes, and taking appropriate corrective action, users can reduce the risk of Wire Stretch Hose failure and help maintain stable pipeline operation.
