l前言钢管在储存和运输等方面都存在防腐问题。对短期储存的钢管，防腐问题不明显；而对外贸出口的钢管，因运输周期较长，海上环境恶劣，若不将钢管表面作防腐涂层处理，外表面将出现大面积锈蚀，严重影响钢管的表面质量。目前，国内有些厂家仍采用油溶性漆。但油溶性漆毒性大
l Preface steel pipe in the preservation and transportation of corrosion problems exist. For short-term storage of steel pipe, the anti-corrosion problem is not obvious; while the export of steel pipe due to the long transport cycle, the harsh marine environment, if the surface of the steel pipe for anti-corrosion coating, the outer surface will appear a large area of corrosion, seriously affecting the pipe The surface quality. At present, some domestic manufacturers still use oil-soluble paint. But oil-soluble paint toxicity
