Advantages And Disadvantages Of Composites In Oil Industry

Composite materials are multiphase materials obtained through the artificial combination of different materials in order to attain properties that the individual components by themselves cannot attain. They are not multiphase materials in which the different phases are formed naturally by reactions, phase transformations, or other phenomena. An example is carbon fiber reinforced polymer. Composite materials should be distinguished from alloys, which can comprise two more components but are formed naturally through processes such as casting. Composite materials can be tailored for various properties by appropriately choosing their components, their proportions, their distributions, their morphologies, their degrees of crystallinity, their crystallographic textures, as well as the structure and composition of the interface between components. Due to this strong tailor ability, composite materials can be designed to satisfy the needs of …show more content…

Due to the use of them, mass of construction is reduced up to 80%. Composites are already greatly used for the production of pipe systems for fluid transport, pressure vessels, drill pipes and their couplings, tanks for fluid storage, risers, pipes for "coiled drilling" installations, partitions on platforms for the protection against fire etc. Basic advantages of the use of composite materials when compared to conventional material which is steel, are reduction of mass of primary and secondary constructions, introduction of new technologies (for example installation of conducting infrastructures into drill pipes), better physical and chemical characteristics (corrosion resistance, buckling strength), longer life time of the construction (for example within 25 years carbon fibers lose 2-10% of initial strength), easy installation of the construction, higher safety at work, and minimum
