Strengthening Pipeline Materials to Improve Their Service Life

The risk of duct aging increases as a plant gets older. The coating material of the exiting exhaust ducts in TSMC is in compliance with relevant acid and alkali resistance specifications. Nevertheless, to avoid potential risk of corrosion and leakage as a result of long term use and extreme processing temperature, the TSMC Industrial Safety and Facility Department analyzed the molecular structure of various acid and alkali resistant materials, and evaluated the quality and cost of applying these materials. In 2018, the inner protective coating of the exhaust gas pipelines was replaced by the build-in lining, which effectively solved the uneven thickness problem of the protective coating, and increased the thickness of the protective layer by 20 times, significantly improving the durability of the pipeline by more than 60%.
