According to the Shahid Tondgooyan Petrochemical public relations and international affairs, in the year named "Production, Supports, and Removal of Barriers" and in the program to maintenance, removal of barriers, and bottlenecks in production, the Cathodic Protection System of PET2 in Shahid Tondgooyan Petrochemical Company was updated by local experts and using the power of knowledge-based companies to have production sustainability.
The Cathodic Protection System has a significant impact on the production process by preventing 
corrosion of the outer surface of underground pipelines beside reservoir floors in various industries, especially the oil and petrochemical industries. Since the companies' fire water lines are under the ground and their protection increases the safety factor in the industries, permanent monitoring and updating of this system are among the essential programs for stable and permanent production.
Shahid Tondgooyan Petrochemical Company, as a manufacturer of strategic products in the chain of Polyethylene Terephthalate (PET) and Pure Terephthalic Acid (PTA), repeatedly strives to improve the quality and quantity of products in the best possible way. The company's management pays special attention to factors related to production, including Cathodic Protection System.
So, experts and specialists of Shahid Tondgooyan Petrochemical Company, using the capacity and capability of Iranian knowledge-based companies, have designed and updated the Cathodic Protection System of the PET2 that three new anodic substrates and the upgrade of the rectifier are measures taken in this program.
In addition to this program, other measures have been taken by Shahid Tondgooyan Petrochemical Company to optimize this system, such as replacing 40 anodes for old anode substrates, checking and monitoring the leakage status of cathodic protection current, and performing corrective measures by isolating lines, as well as replacing and installing five one-way transformers.
The condition of the protection system of the underground pipelines of the complex is at a desirable level With technical measures. However, to increase the protection factor of the Cathodic System, the necessary planning has been done to design and upgrade the system in other units of the complex.
