Fajr Energy executes internal Cathodic protection of firefighting pipelines
Fajr Energy Persian Gulf Company hit for the first time in the country the target of putting the internal Cathodic protection project of the company's fire-fighting water pipes into practice.

As Fire-fighting systems and related equipment are deemed to be one of the main apparatus to increase the security coefficient in various industrial and administrative places, the fire-fighters can significantly reduce the risks and any possible damages caused by fire on the pipelines.  Water in here is one of the most effective means applicable by the firefighters in such a situation, the availability of which has an effective role in accelerating the firefighters' performance to put off the fires faster.

As, Fajr Energy Persian Gulf Company is currently known as the supplier of the fire-fighting water for the Especial Petrochemical Economic Zone companies in the region, it cannot go on without the fire-fighting water, so this very issue is considered to be one of the most vital parts of safety and the fire-extinguishing characteristics of the companies in this region.

Thus, to increase the immunity of the regional companies, it is very important to make sure whether the firefighting water supply pipelines are functioning properly or not. Hence force, the internal corrosion in the industrial water pipes, including those pipes for cooling and fire-fighting waters has so far been considered as one of the industrial problems in the region, so regarding the importance of this very issue, the act of controlling of them has never been forgotten.

The main cause of these damages which is also imposing huge expenses on the industry from the point of view of corrosion, seems to be the lack of controlling and proper maintenance of the systems. Factors such as water temperature, PH, the water current rate, its chemical composition, and most importantly, the amount of oxygen dissolved in the water have especial effect on the amount of internal corrosion caused by water, as well

It is very important to prevent the phenomenon of corrosion in the interior side of the fire-fighting water pipelines, because they normally faces various types of corrosion in the long run. As far the internal surfaces of these pipelines are generally free from any sort of coating and on the other hand, the chemical composition of the inflowing water normally undergoes many changes in different time periods, so applying any corrosion control methods can be very important to increase the life of the pipe lines.

Fajr Energy Persian Gulf Company has so far took the necessary measures to increase the lifespan of fire-fighting water pipelines, increase their efficiency and reduce the problems caused by the corrosion of the internal surfaces of this system, and then increase the reliability of the firefighting water pipeline system through defining the internal Cathodic protection project of the pipelines.  This project has been planned and carried out for the first time in the country and has been successfully implemented on a trial basis. Notably, as this type of Fajr Company Cathodic protection project has never been tested globally on fresh water transmission pipes, this very measure is somehow considered to be the first of its kind in the world, as well.

At the beginning of this project, the trial specifications of the internal Cathodic protection system were defined and carried out along with its design for 30 meters of 8-inch pipeline. Then they checked the performance of the internal Cathodic protection system and evaluated the process conditions and the characteristics of the consumed water in different time intervals.

The Cathodic protection project makes it possible both to monitor the outside and inside of the firefighting water transmission pipes and predict the situation and its influence on the pipelines, so, it can easily increase the level of technical knowledge of the personnel in the field of Cathodic protection and finally provide the final solution in the field of increasing the life of firefighting water pipelines.

The most important advantage of the trial implementation of the internal Cathodic protection project of firefighting water pipelines is to decrease the time span, energy consumption and finally the expenses in the Fajr Energy CompanyThis project has so far been carried out on a small scale of 30 meters and has significantly improved the control of the corrosion of firefighting water pipelinesSo the results of this research can be generalized to all the pipelines in the Fajr Energy Persian Gulf Company.

Another noteworthy advantage of this very method, which also makes it a safe and economical one, is its very good compatibility with different water conditions, corrosion consequences, and the temperature and pressure situations of the service providence. We can also mention some other advantages of the method, its long time service providence (at least for 20 years), its potentiality to be easily monitored and the possibility of getting ensured of its performance during the time of service providence.

It should also be noted that the costs of applying the internal Cathodic protection method over the said pipelines is much lower than the costs of re-implementing the pipeline laying. Also noteworthy, It is estimated to cost more than 70 billion Rials (at the time of the project's initiation) to replace the pipelines per kilometer, which is far more than the cost of implementing the Cathodic protection system.

The next step should be taken by the experts of Fajr company is to execute the proposed plan and start the implementation stages of the project for 100 meters of firefighting water pipelines of Fajr company, which is to be carried out after the implementation of the Cathodic protection system and a periodical inspection in order to record the results, examine the side effects as well as other supplementary measures.
