Shandong Mingrunchang Chemical Co., Ltd. conducted water pressure AE testing on 12 2000m3 spherical tanks, conducted TODF re inspection on defects, and used conventional ultrasound to determine depth, length, and height to evaluate defects, ensuring the safe use of spherical tanks. Acoustic emission testing also creates huge economic benefits for enterprises, without the need for replacement, cleaning, steaming, scaffolding, polishing, and greatly shortening the inspection cycle.

Anhui Jinsu Manufacturing Co., Ltd. conducted acoustic emission testing on a water pressure test process of an activated carbon adsorption tank to discover congenital activity defects in new pressure vessels and improve manufacturing quality. The overall inspection of the shell and connecting pipe of the carbon adsorption tank was carried out using a combination of triangle positioning and line positioning methods.
