Ultrasonic flaw detection of high frequency steel tube


Ultrasonic flaw detection of high frequency steel tube
High frequency steel pipe in the production process because of its high efficiency, so the quality test of steel pipes with high frequency is particularly important, generally high frequency steel pipe ultrasonic inspection points for online and manual, online high frequency steel pipe ultrasonic wave flaw detection of the installation in the production line, the continuous production of steel for online detection, a defect will alarm, because online ultrasonic testing equipment is automatic. Therefore, the detection of, there will appear the phenomenon of omission and misstatement, so each batch of high frequency steel pipe line also manual ultrasonic pumping test.
steel pipes
Due to its special production process, high frequency steel pipe is used for welding, so the welding defects are not fused. Because of the current and voltage controlled by the machine, it is usually a very long way. But it is necessary to test the detection speed, the speed will affect the efficiency of production, but also easy to cause the increase of steel pipe waste.
High frequency steel pipe in high frequency welding, the use of scraper will be removed, so the weld is almost no more than high, reducing the difficulty of the defect, but should pay attention to the location of the weld in the detection, so as to avoid mistakes.
High frequency steel pipe ultrasonic flaw detection although a submerged arc welded steel pipe is simple, but it is production of high-efficiency, defect is a batch of products, so high frequency steel pipe flaw detection is particularly important.
