First, the function of the ball valve balance hole The balance hole is also called the compensation hole, which refers to a channel inside the ball valve, generally located between the two sealing surfaces above and below the ball. Its role is to balance the pressure on both sides when adjusting the pressure outside the section to ensure the normal operation of the valve. T

Recently, the first 175 mpa ultra-high pressure maintenance test center of Northwest Oilfield was completed and put into use in Xinjiang Laisu Industrial Park. Covering an area of about 23,000 square meters, the center has more than 40 sets of advanced industrial equipment such as 280 mpa watertight and airtight pressure test tables, and more than 50 kinds of oil field mat

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.
