Accurately grasping the wall thickness changes of pipelines and pressure vessels in daily equipment inspection and maintenance is a key link to ensure the safety production of chemical enterprises. Recently, the technical team of Egway Company successfully used the TT700 ultra-thin ultrasonic thickness gauge in a chemical plant to conduct equipment corrosion status assessment tasks, completing an efficient and accurate on-site inspection, timely discovering potential safety hazards, and winning high recognition from customers.

Due to long-term exposure to high temperature, high pressure, and highly corrosive media, there is a risk of wall thickness reduction in the reaction pipeline of the chemical plant. Traditional thickness measurement equipment is difficult to achieve accurate measurement under conditions of coating, curved surfaces, and ultra-thin walls. Customers urgently need a professional instrument that can penetrate coatings and achieve high-resolution measurement.

Engineers from Egway brought in the TT700 ultra-thin ultrasonic thickness gauge and quickly conducted testing based on its performance

In the elbow and weld area that customers are most concerned about, TT700 consistently captures wall thickness data of 0.18mm to 0.22mm with a resolution of 0.001mm, accurately determining severe local corrosion.

The instrument can directly measure without removing the surface anti-corrosion paint, greatly improving the detection efficiency and avoiding the damage to the pipeline protective layer in traditional methods. Under the dimly lit pipe gallery, the backlight display of TT700 is clearly visible; The whole machine weighs only 220g and is flexible to operate with one hand, greatly facilitating high-altitude and narrow space operations. Engineers conduct sound velocity backtesting and calibration on unknown materials on site to ensure accurate and reliable data; The hundreds of sets of data stored during the detection process facilitate the issuance of detailed detection reports and trend analysis in the later stage.

Through system testing, the Egway team discovered three corrosion points with wall thickness lower than the design safety value, and promptly provided repair suggestions to customers, avoiding production stoppages or even safety accidents that may be caused by pipeline leaks. The customer highly praised the performance of the TT700 instrument and the professional ability of our engineers: "The TT700 not only measures accurately and responds quickly, but is also particularly suitable for our testing scenarios with paint, thin walls, and complex on-site environments. It is a practical thickness measurement device that we have encountered in recent years
