From the original import equipment reached 80%, to the Sino Russian second-line and other new projects, domestic equipment reached 100%, more than 4 years, the pipeline company localization equipment more and more. Up to now, the company's localization equipment has covered 2500 kW class oil pump, motor, frequency conversion device, nitrogen type relief valve, sleeve type control valve, electro-hydraulic actuator, etc.. .

Before 2013, most of the oil transportation equipment parts of the pipeline company needed to be imported. After a long period of use, the repair problems were difficult, the replacement cost was high and the cycle was long, which affected the production of oil transportation. Since August 2013, the pipeline company has carried out technical research on the project of localization of key equipment for oil and gas pipelines on the basis of China National Petroleum Special Science and technology special project "localization of key equipment for oil and gas pipelines", and has explored the use of domestic equipment instead of imported equipment. In October 2014, the Qing iron four line, 6 sets of home-made oil pump put into operation, so far stable operation. Since then, equipment localization pump unit has been in the big saddle line, Qing iron three line and four line reconstruction project has been applied, a total cost savings of 130 million yuan. Subsequently, the Qing iron four line of 2 domestic oil transfer valve put into operation. At present, the pipeline company localization of domestic oil control valve cumulative application of more than 13 units, cost savings of about 8 million 400 thousand yuan.

In 2015, the company continued to force in the domestic pipeline equipment, domestic electro-hydraulic actuator in Qing wire, Russian oil transportation increasing supporting engineering, iron line XinMin Railway Station safety renovation project investment with up to 22 units, according to the maintenance period of 10 years, can save the cost of 9 million 470 thousand yuan.

At present, the company's research and development of pressure relief valve in China for the first time to achieve large flow full size dynamic performance test.
