1. Chemical composition test
Chemical composition test is one of the important means to check the quality of seamless steel pipe. Through chemical analysis, the content of various elements in seamless steel pipe can be determined to determine whether it meets the corresponding standard requirements. Common chemical composition test methods include spectral analysis, chemical analysis and so on.
2. Mechanical property inspection
Mechanical properties test is an important index to test the performance of seamless steel pipe. Through the mechanical test, the tensile strength, yield strength, elongation, impact toughness and other mechanical properties of seamless steel pipe can be determined to determine whether it can meet the use of requirements. Common mechanical properties test methods include tensile test, impact test and so on.
3. Dimensional inspection
Dimensional inspection is an important indicator of the appearance and size of seamless steel pipe. Through measurement, the outer diameter, wall thickness, length and other dimensional parameters of seamless steel pipe can be determined to determine whether it meets the corresponding standard requirements. Common dimensional inspection methods include measurement by ruler, thickness gauge, etc.
4. Appearance inspection
Appearance inspection is an important means of inspecting the surface quality of seamless steel pipe. Through visual inspection or with the help of instruments, we can check whether there are cracks, bubbles, inclusions, scratches and other defects on the surface of seamless steel pipe, and determine whether it meets the corresponding standard requirements.
5. Straightness inspection
Straightness test is an important index to check whether the seamless steel pipe is straight or not. Through measurement, the curvature of the seamless steel pipe can be determined, to determine whether it meets the corresponding standard requirements. Common straightness inspection methods include tape measure and optical measurement.
6. Non-destructive testing
Non-destructive testing is a method of detecting internal defects without destroying the seamless steel pipe by using physical methods. Common non-destructive testing methods include ultrasonic flaw detection, ray flaw detection, magnetic particle flaw detection, eddy current flaw detection and so on.
