Quality Defects in the Chemical Pipelines
The chemical industry has become a pillar industry in the economic development in China, and its production benefits have greatly promoted the improvement of China's economic level. However, there is serious pollution for the chemical industry, which poses a serious threat to healthy manufacturing. Unreasonable selection of pipeline models will induce accidents. Therefore, it is necessary to consider the special features of the design and manufacturing of the chemical industry. Analyze the restrictions on the transportation of media in the chemical pipeline. Select reasonable pipeline materials to avoid the influence of factors such as excessive temperature, severe corrosion and low temperature, and improve the quality of pipelines.
In the production process of chemical pipelines, the most important issue is the safety of chemical pipelines. Chemical pipeline materials have an important impact on the safety of chemical pipelines. Under normal circumstances, the materials transported by chemical pipelines are relatively corrosive and have special properties. Therefore, the quality of chemical pipelines must be inspected scientifically.
2. Quality defects in chemical pipelines
(1) Relevant departments not indicating clear responsibility for the safety of chemical pipeline engineering
The supervision department, construction department and relevant government departments don't pay enough attention to design management and there are insufficient supervision and management when managing chemical pipeline engineering. The pipeline construction is performed by the construction enterprise, and the management of the chemical pipeline project cannot be coordinated by multiple departments, which directly affects the construction effect of the construction drawings, cannot clearly check the quality of construction materials, and lacks rationality for the application of construction technology. In addition, after the completion of the construction of the chemical pipeline project, the relevant departments cannot send professionals to inspect the pipeline's quality, easily leading to problems for chemical pipelines in the later period.
(2) Inaccurate construction drawings of chemical pipelines
Under normal circumstances, most of the construction workers perform chemical pipeline engineering management in accordance with construction drawings. If the drawings are not accurate, the construction personnel will perform chemical pipeline construction according to inaccurate drawings, which will lead to safety hazards of pipelines. In addition, in the process of drawing pipeline construction, if designers cannot verify the content of the construction drawings from the geographical environment of the region, and the construction staff proceed step by step and ignore the accuracy of the drawings, it will seriously affect the construction of the chemical pipeline's quality.
(3) Lacking supervision for materials used for pipeline construction
During the construction of chemical pipelines, there are many raw materials involved, including materials for valve equipment, protection devices, pipes, compensators and pipe fittings. The quality of these materials will have a negative impact on the construction of chemical pipelines. In the process of purchasing construction materials, the person in charge should check the qualifications of the suppliers. Analyze whether the construction materials meet the quality standards and they have qualified certificates; carry out a quality inspection for samples. However, in the construction process, companies often use inferior pipeline materials for construction in order to reduce construction costs, and often ignore the quality inspection of materials.
