大口径管道防腐保温“一步法”工艺研究

Study on "One-step" Process of Large Diameter Pipeline Anti-corrosion Insulation

大口径管道泡沫夹克防腐保温"一步法"生产过程中,保温层成型及偏心问题一直未能得到很好的解决。文章从工艺参数的确定进而指导作业线的建立方面进行了深入分析,提出了相应的解决办法,总结出了大口径管道防腐保温"一步法"施工的工艺参数确定方法,并成功地在原油输送管道防腐保温施工中得到应用,达到了满意的效果。

In the process of“one step”process of large diameter pipeline anti-corrosion insulation,the problem of heat insulation layer forming and eccentricity has not been solved well.Froming the establishment of the determination of process parameters to guide the production line are analyzed in this article,and puts forward the corresponding solutions,summed up the large diameter pipeline anticorrosion insulation method to determine the process parameters by construction,this process has been applied successfully in the crude oil pipeline anticorrosion insulation construction,and achieved satisfactory results.
