Embodiment 1

[0071] Taking the steel grade of 0Cr17Ni12Mo2Ti (316Ti) and φ68.3*1.3mm seamless steel pipe as an example, the process method (process flow) of single-channel ultrasonic flaw detection is as follows:

[0072] 1) Preparation of the sample tube. The seamless steel tube with the same external dimensions as the nuclear-grade stainless steel seamless steel tube is processed into a sample tube for ultrasonic flaw detection. An outer wall flaw is processed in the middle of the sample tube, and an outer wall is processed at one port of the sample tube. For flaws, an inner wall flaw is processed on the other port of the sample tube. The dimensions (depth, width, and length) of these three artificial defects are processed according to the product requirements. After the sample tube is processed, it needs to be measured to determine whether it meets the standard requirements;

[0073] 2) The sample tube is debugged on the machine, and the sample tube obtained in step 1) is debugged on the...

Abstract

The invention discloses an ultrasonic flaw detection system for a nuclear-grade stainless steel outer sleeve and a flaw detection method thereof, and the system comprises a box-type detection mechanism, wherein a probe is arranged in the box-type detection mechanism, the end of the box-type detection mechanism is provided with a tube blank hole diameter for the nuclear-grade stainless steel outersleeve to penetrate through, and the probe is a combined probe. The system also comprises an end cover which is arranged at the aperture of a tube blank, wherein a sealing ring is arranged between theend cover and the aperture of the tube blank; a guide sleeve which is arranged on the outer side surface of the end cover, wherein a sealing gasket is arranged between the guide sleeve and the outerside surface of the end cover. The combined probe is a combined probe with a built-in wafer. The system effectively solves the problem of ultrasonic flaw detection of the nuclear-grade stainless steeljacket, and realizes low-cost, high-efficiency and high-quality flaw detection operation.

Description

technical field [0001] The invention relates to inspection equipment for seamless steel pipes, more specifically, to an ultrasonic flaw detection system and flaw detection method for nuclear-grade stainless steel outer casings, especially suitable for ultrasonic nondestructive testing production of 0Cr17Ni12Mo2Ti (316Ti) seamless steel pipes. Background technique [0002] Seamless steel pipes are common metallurgical and steel products. From metal smelting, steel rolling to finished product delivery, a process is required. In order to ensure that the processing quality of seamless steel pipes meets the corresponding technical requirements, non-destructive testing is required after the corresponding deformation process. test. [0003] Ultrasonic flaw detection has the characteristics of good directionality, short wavelength, small loss in high-density solids, and large reflection on the interface of different density media. , inclusions, corrosion pits, and improperly proces...
