电晕处理技术在泡沫夹克管“一步法”作业线上的应用

The application of corona processing technique on the "one-step" operation line of foam jacket

在泡沫夹克防腐保温钢管“一步法”作业线上应用电晕处理技术，解决了泡沫夹克管容易“脱壳”的难题。本文介绍了电晕处理技术的设计要点、工艺参数及经济效益。

By using corona processing technique on 'one-step' operation line of foam jacket on steel pipes for corrosion prevention and thermal insulation, the problems of the jacket, s vulnerability to strip off and water penetration, accelerating corrosion of pipelines are eliminated. This paper mainly introduces the design essentials, technological parameters and applications of the technique.
