Abstract

The invention provides a pulsed eddy current testing device with multiple probes. The pulsed eddy current testing device comprises an annular plate. The annular plate is provided with two connecting ends, a hasp is fixedly connected with the two connecting ends of the annular plate, the probes and a handle are evenly distributed on the annular plate, an installation hole is formed in the handle, and a handspike is arranged in the installation hole. According to the pulsed eddy current testing device with the probes, by fixing the probes on the annular plate, simultaneous testing of different hook faces of a pipeline is achieved, and working efficiency is greatly improved. By arranging the telescoping handspike, the testing of a lateral pipeline and a pipeline located on a higher position in the vertical direction can be achieved.

Description

technical field [0001] The invention belongs to the field of pulsed eddy current detection, in particular to a multi-probe pulsed eddy current detection device. Background technique [0002] Non-destructive testing technology is to detect various engineering materials, parts, Internal and surface defects such as structural parts, and make judgments and evaluations on the type, nature, quantity, shape, shape, position, size, distribution and changes of defects. Non-destructive testing technology mainly includes five testing methods: radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing and eddy current testing, and pulsed eddy current testing technology, as a branch of eddy current testing in non-destructive testing, has its unique advantages, mainly including It has the advantages of no coupling agent, rich spectrum, fast response speed, and strong penetration depth. However, when using pulsed eddy current testing technology for pipeline te...
