Abstract

Un tramo de tubería para el tendido submarino, compuesto de una cantidad de tubos de acero (1) soldados entre sí frontalmente, con un aislamientoanticorrosivo (2) de plástico que incluye al menos una capa y con un dispositivo de sustentacion dispuest o por fuera en el tramo de la tubería, que debedimensionarse teniendo en cuenta el volumen y el peso de los tubos de acero (1) de forma tal que el tramo de tubería flote en la superficie del agua. Aquí, eldispositivo de sustentacion está conformado c omo un revestimiento (39 aplicado sobre el aislamiento anticorrosivo (2) de un material celular de poro cerrado yque rodea la superficie del aislamiento anticorrosivo (2) de plástico que incluye al menos una capa y con un dispositivo de sustentacion dispuesto por fuera enel tramo de la tubería, que debe dimensionarse teniendo en cuenta el volumen y el peso de los tubos de acero (1) de forma tal que el tramo de tubería flote enla superficie del agua. Aquí, el dispositivo de sustentacion está conf ormado como un revestimiento (3) aplicado sobre el aislamiento anticorrosivo (2) de unmaterial celular de poro cerrado y que rodea la superficie del aislamiento anticorrosivo (2) al menos por sectores y que está adherido firmemente de modo quelas fue rzas de sujecion axiales que aparecen en el tendido de tubos al hundir el tramo de tubería sean transmisibles a los tubos de acero (1), y donde elmaterial celular respecto de su porosidad (estructural celular) y las propiedades mecánicas del material utilizado a tal fin se seleccionan de manera tal queel volumen del dispositivo de sustentacion en el tendido de tubos es comprimible tan fuertemente por la accion de la presion estática del agua por sobre laprofundidad prevista del tendido que las f uerzas de sustentacion que actuan sobre la parte sumergida del tramo de tubería sea más pequenas que su peso.A section of pipe for submarine laying, composed of a quantity of steel tubes (1) welded together frontally, with an anticorrosive insulation (2) of plastic that includes at least one layer and with a support device arranged or outside in the section of the pipe, which must be sized taking into account the volume and weight of the steel tubes (1) so that the pipe section floats on the surface of the water. Here, the support device is formed as a coating (39 applied on the anticorrosive insulation (2) of a closed pore cellular material and that surrounds the surface of the plastic anticorrosive insulation (2) that includes at least one layer and with a device of support arranged on the outside of the pipe section, which must be sized taking into account the volume and weight of the steel tubes (1) in such a way that the pipe section floats on the water surface. Here, the support device it is formed as a coating (3) applied on the anticorrosive insulation (2) of a closed pore cell material and that surrounds the surface of the anticorrosive insulation (2) at least by sectors and which is firmly adhered so that they were fastening axes that appear in the pipe laying when the pipe section sinks are transmissible to the steel tubes (1), and where the cellular material with respect to its porosid ad (cellular structural) and the mechanical properties of the material used for this purpose are selected in such a way that the volume of the support device in the pipe laying is so strongly compressible by the action of the static pressure of the water over the expected depth of the laying that the support forces acting on the submerged part of the pipe section are smaller than their weight.
