Abstract: According to corrosion situation of gathering pipelines in Tahe Oilfield, corrosion cause of the gathering pipeline is analyzed from corrosion medium, influence of weld seam, impact of CP current and corrosion products. Corrosion control techniques are researched in the facet of material optimization,inhibitor, coating and joint coating, external reinforcement of coating and process optimization. Countermeasures of corrosion control suitable for the gathering pipeline in Tahe Oilfield are put forward.
