Composites are used due to their unique properties, which make them suitable for demanding applications in the oil & gas industry. They have the advantage of being low in weight, which eliminates the need for large and exorbitant buoyancy tanks. Composites are inexpensive to install, extremely corrosion-resistant Hydro Flask Hydration 40 Oz Wide Mouth Lava Red UK Sale , and well-suited to increased operating pressures.
Composites are made by matrix combination of different materials. The most commonly used composites are formed by combining epoxy, phenolic, or polymer (polyethylene, poly-vinyl-denefluoride Hydro Flask Hydration 40 Oz Wide Mouth Graphite Grey UK Sale , and polyamide) matrix with glass fibers, carbon fibers, or aramid fibers.
During the construction of a riser (a pipeline that connects the rig of water surface to the well bore at seabed), thermoplastic polymer matrix reinforced with glass or carbon fibers is used. This matrix is wound around its steel reinforcement, which drastically reduces its weight. In some cases Hydro Flask 12 OZ Hydro Flask Coffee UK Sale , epoxy matrix reinforced with carbon fibers may be used. In the construction of pipe systems for fluid transport and storage tanks, fiberglass composites are used. They are formed by combining polymer matrix (generally, epoxy matrix and vinyl ester matrix) with glass fibers.
