摘　　要：根据输送海洋天然气管道凝析液的服役特点,确定了研制新型的无溶剂内减阻防腐涂料的涂层类型、性能指标、检验方法和测试标准。通过配方优化设计和工艺试验,最终研制出了适用于非腐蚀性气体管道输送的常温无溶剂改性环氧涂料以及适用于天然气凝析液管道输送的中温无溶剂改性环氧涂料内减阻涂料。涂料经第三方检测机构检测,其性能及指标符合设计的要求。并通过生产线涂覆工艺的现场实施,内减阻防腐涂层质量和施工工艺满足规模化生产的需要。According to the service characteristics of marine condensate gas pipeline, determine the development of new two types solvent-free coatings of drag reduction, including technological performance index, test method and test standard of coatings. Through the formula optimization design and pilot-plant test, finally the two types of solvent-free epoxy modified coating are suitable for anti-drag natural gas pipeline at room temperature and for anticorrosion gas liquids pipeline at medium temperature. Coatings were tested by the third party inspection agency, its performance indicators meet the design requirements. And through the field production line applied, the anti-drag and anti-corrosion coatings quality and application had met the needs of the mass production.
