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 condensate in transporting natural gas pipeline, the types of coating, performance index, test methods and test standards for the development of new non-solvent drag reducing anti-corrosion coatings were determined. Through formula optimization design and process test, finally developed a non-corrosive gas pipeline at room temperature solvent-free epoxy coating modified for natural gas condensate pipeline transit solvent-free epoxy coating epoxy drag reduction coating. Paint testing by third-party testing agencies, its performance and indicators meet the design requirements. And through the production line coating process on-site implementation, within the anti-corrosion coating quality and construction technology to meet the needs of large-scale production.
