In 2014, DAR JIA was commissioned for renewing the wastewater storage tank that require to use the N-PTFE lining technique for a renowned petrochemical plant in southern Taiwan. Measuring 8,500mm (diameter) x 9,500mm (height), the volume of the equipment is 537KL. It is used to store solvents such as waste water/EDC/HCl. PTFE has excellent corrosion resistant properties toward acid, alkai and organic solvents. In addition, it also features heat/cold resistance as well as weather resistance, and it will not be affected by changes in temperature or exposure to the atmosphere over a long period of time.
