Old coatings displacement is a necessary measures taken for elongating the service life of buried oil/ gas pipeline. The analysis and discussion have been made on the problems existed during the displacement by Qinhuangdao Oil Transportation Company. It is concluded that the standpoint which the service life of asphalt coating was 20-year is not correct on thoery,but the year should be an average service life and not treated as the same;the resistivity data of coating measured according to the current measurement method can not instruct the ageing extent of the coating;the old coating displacement is difficult to conduct because of inconvenient construction in the field. It is suggested that the displacement program should be worked out on the base of inspection;the displacement program of coatings should be firstly based on the results of leakage detection and bellhole inspection, secondly on analysis of the inspection of coating resistivity and daily inspection records;the displacement should be combined with coating repair;the quality supervision must be strenghened;the proper materials and new methods have to be selected to conduct the renovation and inspection of pipeline coatings.

埋地长输油气管道的防腐绝缘层大修理是延长管道运营寿命的必要措施。介绍了秦皇岛输油公司所辖管道的防腐大修情况,分析并讨论了防腐大修中存在的问题,认为:第一,理论上认为沥青防腐绝缘层寿命为20a左右的观点并非合理,20a应是平均寿命,不能一概而论;第二,用现行的防腐绝缘层电阻率的测量方法得到的数据不能可靠地说明防腐层老化程度;第三,防腐大修现场施工困难,质量难以保证。建议:防腐大修方案应在加强管理和实际检测的基础上制定;防腐大修选段判定的主要依据应以检漏和开挖坑检为主,以测量管道防腐绝缘层电阻率及日常资料分析为辅;防腐大修与维修相结合;加强质量监督;选择适用的材料并利用新技术进行管道防腐层的维修和检测。

In light of pipeline coating aging problem, puts forward two plans; coating repairing and CP station increasing and makes economic comparison and analysis to the two plans individually. Because of high cost in coating repairing and difficulty to reach construction quality, measures for coating inspection and repairing , partial maintenance and CP station increasing can be applied to prolong coating overhaul cycle and life span when short of capital, which can obtain optimum economic...

In light of pipeline coating aging problem, puts forward two plans; coating repairing and CP station increasing and makes economic comparison and analysis to the two plans individually. Because of high cost in coating repairing and difficulty to reach construction quality, measures for coating inspection and repairing , partial maintenance and CP station increasing can be applied to prolong coating overhaul cycle and life span when short of capital, which can obtain optimum economic benefit. The article recommends that seven CP stations be installed to drop insulation resistivity of coating down to 200 Ω·m2 and below before coating overhaul construction.

针对管道防腐层老化的问题,提出了进行大修和增设阴保站两种方案,并分别对这两种方案进行了经济对比分析。防腐层大修费用高,施工质量难以保证。在资金紧张时,采用加强管道防腐层检漏和补漏、进行局部维修和增设阴保站的方法以延长防腐层大修周期和使用寿命,可以获得最佳经济效益,提出了增设7个阴保站,使防腐层绝缘电阻率降至200 Ω·m~2以下时,再进行防腐层大修的建议。

A new coating-spraying technique,high-pressure air-free spraying technique,has been developed and tested in the light of the serious corrosion and scale deposit existed in the sour natural gas and brine pipeline. The result shows that the polyurethane modified epoxy primer (finish painting)has perfect performence in water resistance,strong acid and/or base resistance,sulphide resistance and atmospheric corrosion resistance. The painting process, principle of high-pressure air-free spraying and field coating...

A new coating-spraying technique,high-pressure air-free spraying technique,has been developed and tested in the light of the serious corrosion and scale deposit existed in the sour natural gas and brine pipeline. The result shows that the polyurethane modified epoxy primer (finish painting)has perfect performence in water resistance,strong acid and/or base resistance,sulphide resistance and atmospheric corrosion resistance. The painting process, principle of high-pressure air-free spraying and field coating repair are introduced,and the technical-economic evaluation has been made between the new method and typical method,some suggestions have been proposed.
