Inspection of various kinds of steel pipes



　　There are some damage in steel pipes that we cannot figure it out with our naked eyes. We have to count on various test equipment to help us at this situation, whether you choose seamless steel pipe or ERW steel pipe, it is necessary to clear about the inspection methods.
　　We can see that there are three main inspections ways according to "who" is the inspector. First of all, we can make self-inspection in factory. This would make suppliers guarantee their steel pipe's quality before they sell to customers. Of course, the third party inspection would give more trust to customers so that this is the second way to inspect the product. In addition, customer inspection by themself would give them more trust before they purchase the product too.
　　What's more, the detailed inspection methods would be list here:
　　Chemical composition
　　Mechanical property: yield strength, tensile strength, bend
　　Dimension testing
　　Visual inspection
　　Non-destructive inspection:
　　Magnetic flux leakage testing
　　Utrasonic testing
　　Eddy-current inspection
　　Metallographic analysis
　　Hydrostatis test
