In addition to the future to do a good job in scientific planning of the construction of the pipeline design and combat and prevent future damage line have been established violations, illegal behavior, to ensure the safety of pipeline operation，especially need to attach importance to pipeline construction and maintenance in the process of welding and anti-corrosion technology and construction quality problems.
    Since the last century seven or eighties, our country built the crude oil pipeline, Oil and gas pipelines and additional facilities damage phenomenon is very serious, pipeline surrounding building, digging, indiscriminate drilling problem is very prominent, and by the material, welding, testing technology and other factors, and after 30 years of operation, Oil and gas pipeline accident in our country began to gradually enter the lot. Since the fall of 2013, the central government for pipeline safety problems.
    On September 1, 2014, the state council committee issued 《about further to develop oil and gas pipeline hazard completed the renovation of the notice》, Pointed out that the total screening out the oil and gas pipeline tie up, lack of safety distance, does not meet the safety requirements cross through the safe hidden trouble of nearly 30000, an average 2.5 per 10 kilometers there are hidden dangers. Pointed out that the total screening out the oil and gas pipeline tie up, lack of safety distance, does not meet the safety requirements cross through the safe hidden trouble of nearly 30000, an average 2.5 per 10 kilometers there are hidden dangers. Then on October 30, and released by the general office of the state council concerning the establishment of oil and gas pipeline safety hidden dangers rectification work leading group of the state council notice, marked the oil and gas pipeline safety hidden dangers rectification work leading group of the state council formally established, its main duty is unified leadership national oil and gas pipeline safety hidden dangers rectification work.
    《The in-depth development of oil and gas pipeline hazard completed the renovation of the notice 》requirements, before June 2015 to screen out all of the major, form an airtight space renovation work, hidden trouble in June 2016, before the hidden trouble ZhengGaiLv reached 80%, in June 2017 screening out all the hidden treatment. This requirement has been clear about the future three years schedule of pipeline safety management, at the same time, it is reported that China's petrochemical industry in the next three years will allocate 28.1 billion yuan for pipeline safety management, and China's oil and 70% of China's long distance pipeline.  roughly calculated according to the limited information, the future three years China's oil and gas pipeline safety governance may cost 100 billion yuan, at least not less than 50 billion yuan. Significance of the amount of big, the weight of responsibility, giant, relevant departments and enterprises have to be taken seriously.
    The writer think, Pipeline safety planning, construction, operation, maintenance of the four major dimensions, therefore, pipeline safety concept includes planning security, construction safety, safety operation and maintenance of the four major aspects, with long distance pipeline longest mileage of the United States, major accident statistics show that the pipeline welding defects, corrosion, and the third party construction is the main cause of the accident. The pipeline security reality in our country, the author thinks that, in addition to the future to do a good job in scientific planning of the construction of the pipeline design and combat and prevent future damage line have been established violations, illegal behavior, to ensure the safety of pipeline operation, especially need to attach importance to pipeline construction and maintenance in the process of welding and anti-corrosion technology and construction quality problems. Only in this way, good to complete overhaul of the existing problem of pipeline engineering, guarantee the quality of the new pipelines to this, the pipe manufacturing and engineering construction enterprises requires special attention.
    One ant hole may cause the collapse of a thousand-li dyke, Oil and gas pipeline, especially the pipe outlet of anticorrosive processing quality assurance is particularly important for oil and gas pipelines. The next three years, therefore, crucial action pipeline hazard regulation to undertake pipeline overhaul engineering enterprise engineering technology, ability of organization and management put forward higher requirements.
    First of all is the pipeline overhaul project management problems, How to arrange the pipeline construction, anticorrosion construction, construction supervision, tripartite relationship to achieve efficiency and maximize the efficiency of management of technology? The initial construction phase in pipe to pipe laying for the main tasks, pipeline construction in a dominant position, corrosion protection is given priority to with the workshop pipeline anticorrosion pretreatment, the anticorrosion repairing work is complementary, anti-corrosion construction as a whole in a secondary position, the last stage of pipeline overhaul, anticorrosive coating repair become the main task, with field anti-corrosion construction is given priority to, replace pipe is complementary, the role of anticorrosion construction even more crucial, contribution is more important,  therefore, pipeline construction and pipeline overhaul of the technical and economic characteristics and their respective late in the initial construction and pipeline overhaul tasks in the change of relative position, we found that the pipeline overhaul project need by professional anti-corrosion company as responsible for the overhaul quality of the overall operation of the main body, not dominated by the original pipeline project owner again. such a system arrangement to strengthen the professional pipeline repairing construction, is of great significance to improve the quality of anti-corrosion engineering. Again, the past has shown that even independent legal construction supervision party, but if quality belonging to the same parent company or corporation, is also difficult to strictly control the real engineering standards, the construction of effective restriction. Therefore, it is necessary for the pipeline construction project and anticorrosion overhaul engineering into the independent supervision party, and, with design, construction supervision, overhaul, should have the ability to grasp the professional anti-corrosion standards. Pipeline engineering to anti-corrosion all aspects of this appeared to be an important hidden project to give enough attention.
    Anticorrosion enterprises how to improve the engineering technical ability through self cultivation, but also the realistic problems of the present. Today, the anti-corrosion equivalent of pipe and material brush anti-rust paint era is over, For decades, the anticorrosion materials, corrosion products, anti-corrosion technology, great changes have taken place in the market, technology, mechanization, environmental protection, green represents the anti-corrosion industry development direction in the future. Industry threshold is higher and higher, anti-corrosion industry to economic contribution is becoming more and more big, Corrosion protection industry in China has accounted for 1% ~ 1.5% of GDP, total more than 700 billion yuan, with three years of pipeline overhaul tasks, the pipeline anticorrosion enterprises in our country not only ideological value, on the positive action, more need to ensure the quality, ensure progress.To this end, anti-corrosion, on one hand the enterprise needs to manage, grasping technology, to promote technological progress and efficiency of growth management optimization.To strengthen the enterprise internal management, optimize the process, perfect the internal control, to motivate the staff of good.Must strengthen the anticorrosion materials, technology research and development, strive to master as quickly as possible to high performance polyethylene liquid epoxy powder, high temperature resistant, high temperature resistant coatings and 5 deep layer of polyethylene, polypropylene coating for high-end materials and technology.Only in this way can calmly deal with challenges of anti-corrosion industry technical standards continue to improve, and through the outstanding contributions of anticorrosion engineering change society for the anticorrosion construction engineering subsidiary is the status of the mistakes.Anti-corrosion industry of new era has come, oil and gas pipeline overhaul project startup is to unlock the doors of the anticorrosive enterprise entered a new era.
