Deeply rooted in gas‑flow measurement for the steel industry—our company’s pipeline inner‑wall thickness‑measurement technology has been successfully deployed at Tianjin Steel United.


Deeply rooted in gas flow measurement for the steel industry—our company’s pipeline inner-wall thickness‑measurement technology has been successfully implemented at Tianjin Steel United.

During long-term operation, pipelines carrying blast furnace gas, coke oven gas, and other gases tend to accumulate deposits on their inner walls—such as iron oxides, aluminosilicate salts, tar, and dust—leading to wall‑adhering scale. This buildup reduces the pipe’s internal diameter and compromises flow‑meter accuracy, posing a common challenge that affects process control and the safe operation of equipment. Conventional methods for measuring wall thickness are costly, fail to provide an intuitive assessment of deposit conditions, and thus fall short of addressing real‑world field issues.

Addressing the pain points of this operating condition, Fengrun District of Tangshan City Outlook Automation Equipment Co., Ltd. has successfully completed the inspection project for impurity adhesion on the inner walls of gas pipelines at Tianjin Xintian Steel United Special Steel Co., Ltd., marking the practical implementation of this technology. 。

During this on-site operation, our company utilized a self-developed measurement device to conduct an inspection of internal impurity deposits along the inner wall of a DN900‑diameter gas pipeline. Employing a visual‑inspection camera, we performed a field survey to accurately assess the actual condition of scale buildup on the pipe’s interior and pinpoint the root cause of flow‑metering deviations.

The implementation of this project has addressed the longstanding issues in the steel industry—excessive deviations in gas flowmeter measurement data and a lack of empirical validation—providing field‑measured reference data for pipeline descaling and maintenance as well as for on‑site flowmeter calibration, thereby ensuring more stable operation of the enterprise’s production systems.

This project fully demonstrates the reliability and expertise of Zhanwang Automation’s in-house‑developed wall‑thickness inspection system, highlighting our company’s deep technical expertise in flow measurement within the metallurgical industry. Moving forward, Zhanwang Automation will continue to deepen its commitment to industrial automation and flow‑measurement solutions, leveraging proven on‑site deployments and dependable technical services to contribute to the revitalization of China’s national industries.
