The aim of this study is to carry out a feasibility study for the use of four different types of steel pipelines to achieve
the best type to be used for Natural Gas installat ions in the Egyptian coastal areas. Steel pipes that use in this purpose
has exposed to different experimental tasks such as; morphology, hardness, machinability, bending, static pressure and
corrosion behaviour. The results according to the technical feasibility study indicate that the Coru's pipe, El-Nasr's
pipes and the Crane's pipes can be satisfactorily used in Egyptian coastal areas respectively. The El-Nasr's pipes gave
good properties and best cost compared to the Coru's pipes. In same time more acceptable instead to the other
investigated types in the Egyptian coastal areas
