Acoustic emission inspection device for storage tank base plate corrosion

Abstract

The invention discloses a detection device for storage tank base plate corrosion. The device includes acoustic emission inspection sensors adsorbed near the bottom of the storage tank through a magnet base, an acoustic emission detector connected to the acoustic emission inspection sensor through a data line, and a display connected to the acoustic emission detector. The magnet base comprises a hoop sleeving near the bottom of the storage tank; the hoop comprises two semicircular hoop rings detachably connected in a splicing way; 2-6 acoustic emission sensor cavities are uniformly arranged along the circumferential direction of the hoop; the sensor cavity is a cylinder with openings on both ends; the positions installed with the sensor cavities on the hoop are provided with through holes communicated with the sensor cavities; the front side wall of the sensor cavity is provide with an inverted U-shaped wire slot; and the top of the sensor cavity is detachably provided with a spring gland. The device facilitates the positioning and the installation of a plurality of acoustic emission inspection sensors along the circumference direction of the outer wall of the storage tank, not only improves the work efficiency, but also makes the effect of the measuring signal more accurate.

Description

technical field [0001] The invention belongs to the technical field of equipment detection, and in particular relates to an acoustic emission detection device for storage tank bottom plate corrosion. Background technique [0002] As a kind of static equipment for storage media in petroleum and chemical industries, storage tanks are widely used. However, when applied, the bottom plate of the storage tank is more prone to electrochemical corrosion, and the degree of corrosion is more severe than that of the tank wall. Sometimes, corrosion and perforation may even occur. The phenomenon of oil leakage. The bottom of the tank is not easy to inspect and repair, and it is also a place prone to corrosion. When the bottom plate is welded, the anti-corrosion coating near the weld is often burned off, which increases the severity of corrosion. The tank body is not only easy to corrode near the weld, but also the surrounding parts that are easily corroded. If the tank body is not well ...

Problems solved by technology

Due to the influence of the above factors, regular on-site storage tank testing is difficult and affects safe production, and the site often lacks effective basis to judge whether to open tank testing, resulting in waste of human and financial resources
