Quality Inspection:

Mechanical property testing: Through testing methods such as tensile test, impact test and hardness test, the mechanical properties of stainless steel tubes, such as tensile strength, yield strength, elongation and impact toughness, are evaluated.
Dimensional inspection: By measuring the dimensional parameters such as outer diameter, wall thickness and length of the stainless steel pipe to ensure that they are in line with the specified dimensional requirements.
Surface inspection: The surface of the stainless steel tube is inspected, including observation of the presence of cracks, scars, oxidation, corrosion and other defects, which are evaluated and classified.
Corrosion testing: The corrosion resistance of stainless steel tubes in specific corrosive environments is evaluated using appropriate corrosion test methods, such as salt spray testing, corrosive media immersion, etc.
Non-destructive testing: use nondestructive testing methods, such as ultrasonic testing, radiographic testing, magnetic particle testing, etc., to detect defects such as cracks, inclusions, etc., that exist inside the stainless steel tube.
