Application of Interpolation Recovery Technique of Polyethylene Pipes in Tahe Oilfield

The corrosion of metal pipeline frequently occurring in Tahe oilfield which restricts the security of oil and gas production seriously. High density polyethylene (HDPE) interpolation recovery technique as an online pipeline repair technology has good mechanical characters of metal pipelines and good corrosion resistance of non-metallic pipelines. This technique was used in pipeline-repair and achieved good results for improving the anti-corrosion performance of pipelines.
