Stress corrosion
Stainless steel hoses are prone to stress concentration when subjected to pressure, temperature and fluid impact. When the stress exceeds the yield strength of the material, stress corrosion cracks will occur.
Fatigue corrosion
Stainless steel hoses are prone to fatigue cracks under repeated deformation and stress. Especially under conditions of high temperature, high pressure, high flow rate, etc., fatigue corrosion is more serious.
Welding defects
During the welding process, if the welding quality is poor, welding defects are prone to occur. Such as slag inclusions, pores, etc. These defects will lead to reduced pipeline strength, insufficient pressure, and cracks.
Corrosion products
Corrosion products inside stainless steel hoses, such as rust, welding slag, etc., are easy to form a scale layer on the inner wall of the pipeline. When the thickness of the scale layer reaches a certain level, it will cause the pipeline to narrow or even block. Thus cracks will occur.
