    • A “PROCESS FOR OBTAINING PIPES AND JOINTS FROM A POLYMER COMPOSITE” comprising an inner pipe (1), 3.0 to 8.0 mm thick, made of fiber glass with an epoxy resin matrix for resisting the corrosion of the produced fluids and the abrasion of the solid suspended particles. They are made in a metal polished mold through the “filament winding” process with roving thread at a winding angle of 52° to 55°, impregnated with epoxy resin and catalyzed with an aromatic amine, anhydride and aliphatic amine-based cold cure agent, in order to stand chemical attacks and temperature, with the ends being made from molds with a molded thread made of an epoxy resin and carbon fiber compound, wherein the outer face suffers a sanding down process which decreases brightness and adherence in order to accommodate a second layer of “filament winding”, with roving thread at a winding angle between 80° and 85°, 5.0 mm and 8.0 mm thick, impregnated with cold cured cobalt accelerated polyester resin, with an added silica-based charge, with a weight of 40/60 which is deposited through gravity spillage intertwined between the filament winding layers, structured so as to mechanically assist in case of impacts, providing assistance to the product's structural protection, increasing mechanical resistance, essentially as regards impacts and loads on wheels, so that over the second layer a 1.0 to 4.0 mm thick cold cured third polyurethane layer is deposited, the aim of which is providing the pipe with a metal structure, increasing its resistance to impacts and the elements.
    • A“用于从聚合物复合材料获得管道和接头的方法”包括由3.0至8.0mm厚的内管(1)制成的具有环氧树脂基质的玻璃纤维,用于抵抗所产生的流体的腐蚀和固体的磨损 悬浮颗粒。 它们通过“丝缠绕”方法用金属抛光模具制成,粗纱以52°至55°的卷绕角度浸渍,用环氧树脂浸渍并用芳香胺,酸酐和脂族胺基冷固化剂催化, 为了承受化学侵蚀和温度,其端部由具有由环氧树脂和碳纤维复合物制成的模制螺纹的模具制成,其中外表面具有降低亮度和粘附性的打磨过程,以便容纳第二 层叠“长丝缠绕”,粗纱在80°至85°,5.0mm和8.0mm之间的卷绕角度处,浸渍有冷固化的钴加速聚酯树脂,加入二氧化硅基电荷,重量为40 / 60,其通过重力溢出交织在细丝缠绕层之间,结构化以便在冲击的情况下机械协助,为产品的结构保护提供帮助,i 增加机械阻力,基本上关于车轮上的冲击和载荷,使得在第二层上沉积1.0至4.0mm厚的冷固化的第三聚氨酯层,其目的是为管道提供金属结构,增加其对 影响和要素。
