Iranian Researchers Develop New Technique to Repair Gas Pipelines Using Composite Wraps

"There is corrosion in some parts of the gas transmission pipelines. Sometimes, corrosion level in pipelines increases to 80%,” Ali Heydari Moghaddam, a professor at Islamic Azad University's Dezful branch who had taken part at the Asr-e Omid Sirjan exhibition with the product ‘Repair of gas pipelines using polymer composites’ told ANA News Agency correspondent on the sidelines of the event.

“Wrapping the damaged site using composite wraps would increase the strength of the pipe and make the progress of corrosion stop, so that the probability of the pipe bursting from the corroded location would be brought down to zero,” he added.

“Many gas and oil pipelines could face corrosion, meaning that the metal starts to dissolve in the environment where it is located and reduces the thickness of the pipe,” he added, while stressing that using their technique, there would be no need to cut off the gas flow.

“Previously when the gas pipe was corroded, to repair the corrosion location on the pipeline, the gas in the entire area needed to be cut off, and the corroded part must be cut and repaired and replaced. There used to a lot of risks and wastes. But in the polymer composites wraps method, we repair the pipelines without interrupting the gas flow,” Heydari Moghaddam further noted.

The Iranian researcher further pointed out that the research team and his teammates had locally done all the process of developing the technique, raw materials, components, and all the materials used in the production of polymer composite wraps.

Asr-e Omid (Age of Hope) exhibition was held on the campus of Islamic Azad University-Sirjan branch in the city of Sirjan located in the southeastern Kerman Province on May 22-June 1, 2023.
