介绍了预成型复合材料软管内衬修复技术及在胜利油田胜利采油厂φ219×7输油管道上的实际应用。预成型复合材料软管内衬修复技术是管道内修复技术之一,该技术采用浸渍树脂的预成型复合软管,以压缩空气作动力沿管内壁使其翻入管道,经加温固化后,形成紧贴在管内壁上的具有防腐抗渗、强度高的“管中管”。 This paper introduces the repair technology of preformed composite material hose liner and its practical application on φ219 × 7 oil pipeline in Shengli Oilfield. Preformed composite hose liner repair technology is one of the pipeline repair technology, the technology uses impregnated resin preformed composite hose to the compressed air as the driving force along the pipe wall into the pipe, after curing by heating, Form close to the inner wall of the pipe with anti-corrosion impermeability, high strength, “tube in the tube.”
