There are many causes of oil pipeline leaks, mainly the following points.

First, the one-sided pursuit of profits, reducing the investment in safety protection facilities Market economy competition is fierce, in order to reduce costs and the pursuit of high profits, people are eager for quick profits, often there is a fluke mentality, deliberately ignore safety, reduce the investment in safety protection facilities. In addition, state-owned oil companies have always been regarded as leading enterprises, since they are state-owned enterprises have to "stand and toss", it is this misconception makes some managers careless in their thinking, neglecting the management of the production and construction process, the production site run, bubble, drip, leak is precisely the consequence of its poor management, can be found in the management of various leaks often loopholes. Pipeline design is unreasonable, there is a congenital defect resulting in pipeline leakage is one of the main causes of oil pipeline leakage. Usually it is through incompatibility of the sealing structure and sealing materials of the pipeline connection part or the pressure, temperature, nature or environmental conditions of the medium transported by the pipeline. In the process of pipeline installation, non-compliance with the order of operating procedures is bound to be directly related to the quality of the pipeline installation and thus affects the operating time of the pipeline.

Failure of the material forming the facility is the main direct cause of leaks. Therefore, the study of material failure mechanisms is an effective means of preventing leaks. According to statistics, corrosion, cracks and wear are the main causes of material failure, resulting in leaks. Such as pipeline welds with porosity, welding slag or no penetration, cast iron pipelines with cracks and grit; pipelines are damaged by wear; pipeline aging; stress concentration resulting in strength loss; seal failure, etc., all of which can lead to pipeline leakage.

For the above causes of oil pipeline leakage, take effective anti-leakage measures to build layers of defense against leakage.

First, in the mind, should establish the "leak prevention is equal to improve economic efficiency" understanding. Secondly, develop perfect management measures and strengthen labor discipline, which is also an important measure for pipeline leak prevention.

Next, do a good job in the preparation of the pipeline before installation, in the early stage should understand and master the specific situation of the pipeline: including the process flow of the pipeline, the nature of work, the use of pressure, environmental conditions and special requirements; because the size of the allowable leakage of the pipeline is directly related to the investment and operational safety of the pipeline project, it is necessary to determine the allowable leakage of the pipeline in strict accordance with the relevant national standards on the basis of extensive research, to do "by measure"; under normal conditions of use predicted pipeline to achieve a lasting leak-free state sex. At the same time for the pipeline operation may occur in the process of leakage and unexpected events, the development of practical and reliable maintenance preventive measures.

It has been proven that leaks often require double the cost for subsequent treatment. Taking proactive preventive measures before and during construction can effectively reduce the occurrence of leaks and reduce hazards. Therefore, it is both necessary and economically beneficial to pay attention to leakage prevention and make investments in advance.
