【摘要】：石油石化行业中管道的服役工况十分恶劣,很多管道未达其设计寿命而失效报废,造成极大浪费,因此采用表面工程技术对其进行防护和修复具有十分重要的经济价值。主要阐述了热喷涂、自蔓延高温合成和表面镀层等三种表面工程技术对管道内外表面的强化机理,并对它们的实际应用进行了具体介绍。热喷涂技术主要介绍了电弧喷涂、火焰喷涂和等离子喷涂三种热喷涂技术,并分别从它们的工艺原理、适用材料体系、制备涂层性能(结合强度、孔隙率等)以及经济性等方面进行了对比介绍。高温自蔓延合成技术主要从材料和工艺两方面进行了剖析,并对其所制备陶瓷内衬管的连接方法进行了具体介绍。镀层技术主要对钨合金电镀和Ni-P化学镀两种镀层技术的优缺点和适用范围进行了对比介绍。最后针对表面工程技术的特点,对其在石油石化行业的前景进行了分析与展望。
[Abstract]:The service conditions of pipelines in the petroleum and petrochemical industry are very bad. Many pipelines fail to reach their design life and fail to be scrapped, causing great waste. Therefore, it is of great economic value to use surface engineering technology to protect and repair it. The strengthening mechanism of three surface engineering technologies, such as thermal spraying, self-propagating high temperature synthesis and surface coating, on the inner and outer surface of pipeline is mainly expounded. The practical application of them is introduced in detail. The thermal spraying technology mainly introduces three kinds of thermal spraying technologies: arc spraying, flame spraying and plasma spraying. The properties (bonding strength, porosity, etc.) and economy of the coating were compared and introduced. The high temperature self-propagating synthesis technology was analyzed from two aspects: material and technology. The bonding methods of ceramic lined tubes are introduced in detail. The advantages and disadvantages and applicable range of tungsten alloy electroplating and Ni-P electroless plating are compared and introduced. The characteristics of engineering technology, Its prospect in petroleum and petrochemical industry is analyzed and prospected.
