PU material suction hose performs well with its great properties
Metal hoses are generally made of stainless steel. Due to its excellent properties, it plays an important role in various industries. However, in actual work, this hose may be damaged. This damage is mainly caused by stress. Including working stress, phase change stress and residual stress. When stress causes cracking, it is sometimes difficult to detect with the naked eye. Therefore, stress damage is a very dangerous damage. The damage of stainless steel hose stress can be divided into the following three stages.
The first stage is the incubation period
In this stage, cracks are generated as a result of the interaction between the local stretching process and the overall stress. This causes small cracks in invisible places of the stainless steel hose.
The second stage is the development period
In the early stage of cracking, when the cracks gradually appear, the cracks expand under the combined action of the corrosive medium and the metal stress. Then it causes mechanical damage to some parts and produces slender cracks
The third stage
Due to the concentration of local stress in the metal hose, the cracks begin to elongate and expand rapidly. Serious damage is caused in a short time.
