On November 2nd, China's independently developed first 270000 cubic meters of liquefied natural gas storage tank was put into operation in Qingdao, which is also the largest liquefied natural gas storage tank in China. Its operation has greatly improved the natural gas supply guarantee capacity in North China. The first 270000 cubic meter liquefied natural gas stor

In early October, the Dalaoba gas storage in Northwest Oilfield transitioned from the summer gas injection stage to the winter gas production and supply guarantee stage, with an annual working gas volume of up to 200 million cubic meters, effectively ensuring winter natural gas supply. Since last year, in response to the rapid growth of natural gas production in

Sealing surface is the most critical working face of the valve, the quality of the sealing surface directly affects the service life of the valve, and the material of the sealing surface is an important factor to ensure the quality of the sealing surface. Therefore, the following factors should be considered when selecting valve sealing surface materials: ① Corro

Focusing on the "dual carbon" goal, the recent "three barrels of oil" have orderly promoted the adjustment and optimization of energy consumption structure, continuously making efforts in new energy business, and investing with unique characteristics. PetroChina is accelerating the development of onshore new energy and electric transportation business, Sinopec is investing in hydrog

This year's strong growth in China's steel exports is mainly supported by three major factors: One is the strong competitiveness of Chinese steel products. Although the uncertainty of the world economy has increased this year, the global manufacturing industry is in a contraction range due to the downturn (Global Manufacturing PMI Index), frequent manufacturing trade frictions in
