Abstract

The invention provides pulse eddy current testing equipment for a marine pipeline. During detection, people hold a straight rod by hand to drive a detecting probe to move vertically so as to detect the pipeline in the vertical direction or to drive the detecting probe to make a circle so as to achieve annular rotary detection. Through an annular limiting through hole, the pulse eddy current testing equipment can carry out annular detection on the pipeline conveniently, guarantee that the detecting probe and the outer wall of the pipeline are tangential, and improve the accuracy of detection.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic nondestructive testing, and in particular relates to pulsed eddy current testing equipment for marine pipelines. Background technique [0002] In recent years, with the continuous development of offshore oil, the number of submarine pipelines responsible for offshore oil and gas transportation has continued to increase. The marine environment can be divided into five areas: the ocean atmosphere area, the spray splash area, the sea water tidal range area, the sea water full immersion area and the seabed mud area. Area. Among them, the corrosion in the spray splash zone is the most serious. In the spray splash area, the metal surface is periodically wetted by seawater, and is in an alternating dry and wet state. The oxygen supply is sufficient, the salt is continuously concentrated, and the synergistic effects of sunlight, wind and seawater environment lead to the most serious corrosion. ...
