Knowing the causes of aging in stainless steel hoses can lead to targeted prevention measures. The following stainless steel hose manufacturers will introduce the reasons for hose aging: the cracking of stainless steel hoses is caused by alloy corrosion and specific environmental media, such as the use of hoses in chlorine containing solutions; The stress of certain materials stretching DIN sleeve joints, including working stress, phase change stress, and residual stress.

Meeting the above three conditions may cause corrosion damage to the hose. When stress causes cracking, it is sometimes difficult to detect with the naked eye, so stress damage is a very dangerous damage. The damage caused by stress on stainless steel hoses can be divided into the following three stages. The first stage is the incubation period: during this stage, cracks are generated due to the interaction between local stretching process and overall stress, resulting in small cracks in the invisible areas of the stainless steel hose; The second stage is the development stage: in the early stage of cracking, when the crack gradually appears, the crack expands under the combined effect of corrosive media and metal stress, causing mechanical damage to some parts and producing slender cracks; Stage 3: Due to the concentration of local stress in the metal stainless steel hose and hose assembly, cracks begin to rapidly elongate and expand, causing serious damage in a short period of time. Stainless steel hoses are inexpensive and suitable for working in complex environments, which can effectively protect the wiring inside the pipeline. After understanding the causes of aging, they can be prevented in advance, extending the service life of the hoses and improving economic efficiency.
