Because of the complex and diverse hose structure and the different conditions of use, the service life of hoses depends not only on quality, but also on proper use and maintenance. Therefore, even if the product quality is very high, if not properly used and maintained, it will seriously affect its use of quality and service life, and even serious accidents, resulting in property losses. Here are a few things to note:
1, hose and hose assembly can only be used to transport the specified materials, otherwise it will shorten the service life or damage.
2, the correct use of the length of the hose, the hose at high pressure (-4%-+ 2%) The length of the change and by the mechanical movement caused by the length of the change.
3. Hoses and hose assemblies should not be used under pressure (including impact pressure) exceeding the design pressure.
4. Under normal circumstances, the medium temperature of the hose and hose assembly should not exceed-40°c to + 120°c, otherwise it will shorten the service life.
5, hose and hose assembly should not be less than the minimum bending radius of the hose to avoid bending near the pipe, otherwise it will hinder the hydraulic transmission and material handling or damage to the hose.
6. Hoses and hose assemblies should not be used under twisting conditions.
7, hose and hose assembly should be handled with care, should not be dragged on the sharp rough surface, not bending or flattening.
8, hose and hose assembly should be kept clean, internal should be flushed clean (especially acid pipe, spray tube, mortar tube). Prevents foreign bodies from entering the lumen, obstructing fluid delivery and damaging equipment.
9. Hoses and hose assemblies that exceed their lifespan or shelf life must be tested before they can continue to be used.
