Problems solved by technology

[0003] In the prior art, the detection method of pipeline welded joints usually manually detects the pipeline welded joints during construction, and the staff hold the detector in hand to conduct surrounding detection on the pipeline. Human factors are prone to errors, making it difficult to fully discover the existing defects, so it is impossible to fully and intuitively observe whether there are defects in the pipe welded joints and what kind of defects exist

Abstract

The invention relates to the field of PE pipeline weld joint detection, in particular to an annular ultrasonic phased array detection device for PE pipeline weld joint detection, which comprises a base, movable wheels, a fixed groove ring frame, a display, an annular ultrasonic phased array detection assembly and the like, a pair of movable wheels is symmetrically and rotatably connected to the base, a fixed groove ring frame is fixedly installed behind the base, the displayer is fixedly installed on the left side of the base, and the annular ultrasonic phased array detection assembly is arranged on the fixed groove ring frame. Ultrasonic phased array detection is mainly adopted for an electric melting joint, X-ray digital imaging detection is supplemented, and a detection probe continuously scans and detects the welding position of a pipeline, so that a real-time two-dimensional image is displayed in a display, and a worker can clearly observe the joint part conveniently; the two-dimensional image can visually display whether the resistance wire has the problems of dislocation, hole, cold welding, over welding and the like.

Description

technical field [0001] The invention relates to the field of PE pipeline weld detection, in particular to an annular ultrasonic phased array detection device for PE pipeline weld detection. Background technique [0002] With the continuous development and progress of economic construction and social construction, the demand for gas in my country is also increasing. The gas pipeline network has become a very important urban underground public infrastructure. In recent years, cities across the country have laid medium and low voltage on a large scale. Gas transmission pipe network to meet the living and production needs of residents, commerce, and industry. The pipes used for urban gas medium-pressure pipes are mainly steel pipes, gray cast iron pipes, ductile iron pipes, and PE pipes. Pipes need to be welded during construction Check whether there are defects in the joints to ensure the strength and toughness of the pipeline. [0003] In the prior art, the detection method of ...
