Seamless steel tube production process adopting the advantages of ultrasonic testing
Seamless steel tube production process adopts the advantages of ultrasonic testing, ultrasonic testing of the limitations of a. for the defects in the specimen is to study the accurate qualitative and quantitative must still be;B. with complicated shape or irregular shape of the specimen for ultrasonic testing is difficult;C. defect position, orientation, and shape on the test results have a certain influence;D. has a great influence on material and grain size on detection;E. type A pulse reflection method commonly used by detection results show not intuitive, no direct witness record and test result.6479 fertilizer special pipe production process USES the advantages of ultrasonic testing: a. applicable to metal, nonmetal and composite materials, and other parts of the nondestructive testing;B. strong penetrating power, but for larger thickness within the scope of the specimen testing internal defects.Such as metal materials, can be detected for 1 ~ 2 mm thickness of thin wall pipe and plate, can also detect a few meters long steel forgings;C. defect positioning accurately;D. of area type defect detection rate is higher;E. high sensitivity, can detect specimen interior size small defects;F. detection of low cost, high speed, portable equipment, harmless to human body and environment, the use is more convenient.
