This research carries how to do steel pipelines defects repair process by a simple and easy way. At first the region that surrounds the defect is cleaned then the epoxy material is put over the defect after mixing the resin with the hardener well. Epoxy layer dimensions depend on the defect dimensions that exists in the pipe. After that, the specimen is released for a period of time to obtain the setting process. Several types of epoxy were used for preparing series of specimens, which were tested on the pressure set up to estimate the efficiency of this way in the repair, and knowing the pressure values that epoxy layer can carry. A pipe of three holes their radius are equal, was treated by using ALTECO QUICK EPOXY STEEL and the pressure gauge recorded many values that reached 18 bar. The curve, that represents the relationship between the pressure which the epoxy layer carried and its surface area, was drawn. It is found that the most effect factor in the repair process is the specimen preparing and the thickness of the epoxy layer.

In this research paper, engineering properties of structural elements formed of combined metalic sections are compared with the suggested structural element made of steel pipes full of concrete. Such a comparison is carried out for bending and tor sion carrying capacities of above mentioned elements with the same height and crosssection. Structural characteristics and material properties of steel pipes full of concrete are presented. The Study of stress state created in concrete pipes using the general principles of structures mechanics is presented. A special relation to determine the carrying capacity of the concrete pipe under various levels of axial compression is suggested. Theoretical results got on the basis of Euler equation are compared with experimental results of special specimen tested in laboratory. A good agreement between theoretical and experimental results is demonstrated.
Resin based composite considers substantially as a restorative material in clinic. Dentists concern in placement resin composite restorations with Long term survival. Materials and Methods: 20 Non carious human third molars, class I cavity was pr epared in every molar, restored with methacrylate resin composite Tetric EvoCeram. The restored teeth were subjected to thermocycles. Specimen was randomly divided into two groups : the first group 10 restorations, were repaired by Cojet® (3M ESPE, Germany) and restored by Filtek™ P90, the second group 10 restorations also repaired by Cojet ® but restored by Filtek™ Z350 XT. After that all teeth were subjected to thermocycles again, later immersed in 0.5% basic fuchsin solution for 1 s. The teeth were transversely sectioned and observed under a stereomicroscope. The degree of dye penetration was recorded and analyzed. Results: No statistically significant differences in microleakage were observed between two groups either with low shrinkage Silorane resin composite or methacrylate resin composite
In this research work, an epoxy polymer- Carbon Black composite has been prepared and characterized regarding the effects of adding carbon black to epoxy polymer on some structural properties such as polymerization behavior, cross-linking reaction time and yield and some properties e. g. glass transition temperature (Tg), Young modulus (E) and flexural strength (σ). The cross-linking reaction and glass transition temperature were studied by Differential Scanning Calorimetry (DSC), and the mechanical tests were done by Universal Testing Machine.
This research aims to inspect the defects and discontinuities in steel billet by ultrasonic detector. Straight beam probe used to detect a lot number of imported steel billets that clearly have internal defects. The results showed the possibility of initial detection by straight beam probe, and initial defining the types of defects such as, micro and macro cracks, shrinkage defect, blow holing, inclusion, porosity and others type of internal defects. The experiments showed that if the necessity is defining the size of defects, this requires angle beam probe in addition to straight beam probe.
The present work, aims to inspect by ultrasonic method numbers of imported steel billets, which cause stopping and breaking in the production – lines. The inspection was done by using ultrasonic detector,(echo – pulse method), a straight – beam pr obe was used as a transducer and receiver, at the same time. The results of inspection showed the possibility of accurate defect determination in steel billets, and also showed a good agreement between the experimental results and the number of stopping and breaking in production in factory, and also the necessity to use that inspection method in the imported billets which cause the continuous breaking in the production – lines.
