The pipeline company is in the process of pipeline renovation by revising the technical specifications. Imported pumps are introduced to replace DKS-750/550 pumps which are bulky and have low pumping efficiency, and the pumping efficiency is greatly improved. During the construction of the Yichang crude oil pipeline project, on the basis of imports, the pipeline company fully cooperated with the suppliers based on the actual situation of the project construction and the production level of domestic manufacturers, and realized the localization of the two oil transfer pumps in the Daye sub-transportation station. , to speed up the localization process of the oil pump. At present, all the small and medium-displacement oil transfer pumps required by the company have been localized. In terms of valves, the company has also realized the full promotion and application of wedge gate valves and ball valves used in pipeline construction to the imported all-welded ball valves and domestic flat gate valves of the Yonghu-Nanjing crude oil pipeline and Yichang crude oil pipeline. At present, domestic all-welded ball valves are also used in engineering construction. In terms of storage tank materials, the main materials of oil tank construction have also been localized from the original 50,000 cubic meters of storage tanks that were imported to the present. Especially the construction of 150,000 cubic meters of storage tanks, two 150,000 cubic meters of oil storage tanks built in Yizheng in 2004, the two largest oil tanks in China at that time, the main materials of the large tanks were all imported from abroad, the state decided to build in Baisha Bay The commercial storage base is designed with 4 oil storage tanks of 150,000 cubic meters. The relevant departments of the pipeline company have realized localization through cooperation with various steel mills and experts, and have also been used in engineering.
At present, the reporter learned from the Sinopec Pipeline Material Promotion and Supply Cooperation Forum” held on October 14. The pipeline company has successively cooperated with more than 500 international and domestic well-known suppliers. The process of close cooperation with suppliers In the process of mutual benefit, win-win and synchronous development between the two parties, pipeline companies have grown and grown from time to time, many suppliers have achieved technological progress through cooperation with pipeline companies, and new materials, new equipment, and new products have been widely used in pipeline construction, petrochemical pipeline production. The main materials required for construction have basically been localized, which not only saves a lot of construction costs and construction time, but also contributes to the development of my country’s national industry.
The localization of the main materials required for the production and construction of petrochemical pipelines is first reflected in the localization of pipelines and pipes.
At the time, 1975. Due to the limitations of domestic production technology, equipment and other conditions, the entire pipeline can only use straight seam steel pipes, and all the T/S52K plates required for the spiral pipe are imported. In 1998, the reorganization of the two major oil and petrochemical groups not only brought development opportunities to pipeline companies, but also provided more extensive cooperation space for the vast number of suppliers. During the construction of the Ningbo-Shanghai-Nanjing crude oil pipeline in 2002, with the development of domestic iron and steel enterprises and the level of pipe production, with the assistance of the majority of suppliers, all the 16 mm and X60 spiral steel pipes required for the construction of the Yong-Shanghai-Nanjing crude oil pipeline were made in China. Straight seam steel pipes also need to be imported from abroad. During the construction of the Yichang Crude Oil Pipeline and the Sichuan-East Gas Transmission Pipeline, the relevant departments of the pipeline company further strengthened cooperation with suppliers, and various steel mills, pipe mills and research institutes also did a lot of work and gave strong support and cooperation. A series of work such as confirmation of conditions, trial production and inspection, the localization of pipelines and pipes required for the construction of petrochemical pipelines has finally been successfully developed, and the required X65 and X70 spiral pipes and straight seam pipes have all been localized, and have been fully used in Sichuan gas. Construction of the pipeline project to the east.
The main materials required for the production and construction of petrochemical pipelines such as oil pumps, valves, and storage tank materials have also been gradually localized.
