ترجمة الملخص

The research aims to find an effective way and more economic for repairing defects of steel pipelines that areused to transfer water by using composite materials depend on, in their construction,thermoset polymers. To achieve that we suggested many methods for repairing depend on three basic varieties theseare: first layer of Epoxy, second layer of fiberglass reinforced unsaturated polyester and increasing the durability by adding Aluminum powder as a metallic filler material.The results of expanded study, for nature of some Epoxy materials which are available in the market,showed that the best type is ALTECO QUICK EPOXY STEEL where the first layer which made of it,resisted pressure of about 18 bar.It showed,from the experiments, the existenceofa linear relationship between the Epoxy layer thickness and the pressure value that it resisted where the pressure increases by increasing of the first layer of thickness.The setting behavior of unsaturated polyester material of Super Mastic type had been studied by constituting the setting curves that depend on the added penzoyle peroxide percent, which showed increasing in the setting velocity by increasing the peroxide percent.The suggested repair system that consists of first layer of Epoxy and second layer of fiberglass reinforced unsaturated polyester appeared positive results that confirm on efficiency of the followed way in repairing the steel pipelines defects that were represented by holes, their holes radius reached until 1 cm, where this layer resisted pressure its value is 20bar.It also showed increasingthe pressure value, which the final layer resists it, by increasing layers of the fiberglass reinforced unsaturated polyester. Where the pressure value reached 40 bar when we put two layers of the fiberglass reinforced unsaturated polyester. And the pressure increases until 30 bar when we added Aluminum Powder as filler material that leadsto increasing the layer durability and the repair continuance.
