In order to achieve different purposes, gray cast iron can be subjected to different heat treatments after casting. In the production of valve, the heat treatment processes commonly used for gray cast iron valve body and other parts after casting are: the
CCUS flooding in Jilin oilfield realizes the point of carbon to gold
The picture shows Hei125 gas injection platform well in Jilin oilfield.
Jilin Oilfield is committed to low-carbon development and green transformation, and has realized "carbon" into gold. As of March 5, in the 15 years of Changling gas field development, Jilin oilfield has injected 2.91 million tons of carbon dioxide, equivalent to planting nearly 26.19 million trees.
Causes and treatment of internal leakage of natural gas ball valve
Causes of ball valve internal leakage
1. Reasons for internal leakage of the valve during the construction period:
① Improper transportation and hoisting causes the overall damage of the valve, resulting in internal leakage of the valve;
② When leaving the factory, the hydraulic pressure is not dried and anti-corrosion treatment of the valve, resulting in corrosion of the seal
The ninth oil production plant of Daqing Oilfield controls the decline in the old area due to the policy of Tibet
In the first two months of this year, the ninth oil production plant of Daqing Oilfield used diversified means to continuously strengthen the potential of the old area, and crude oil production increased by 195,000 tons year-on-year.
The geological conditions of oil reservoirs developed by No. 9 Oil Production Plant are complex and changeable, including medium permeable oil
Petrochemical industry downstream demand weakened, the economy fell slightly
As the northern Hemisphere enters winter in November, temperatures are generally cooler, economic activity weakens and demand falls. The petrochemical industry represents the demand side of the fuel processing industry and rubber, plastics and other polymer products manufacturing industry boom index growth rate fell significantly. Chemical raw materials and chemical products manu
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
The first ultra-high pressure maintenance test center was put into operation in Northwest Oilfield

The largest liquefied natural gas storage tank in China has been put into use, with a localization level of 95%!
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

The Dalaoba Gas Storage Reservoir in Northwest Oilfield has entered the stage of gas production and supply guarantee
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
Valve sealing surface material selection factors to consider
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
The Three Barrels of Oil Continuously Increase New Energy Business
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
Three Supporting Factors for Strong Growth of Steel Exports
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
Northwest Oilfield's Oil and Gas Production Reached a New High in the First Half of the Year
In the first half of the year, the oil and gas production
equivalent of Northwest Oilfield reached 4.79 million tons, setting a
new historical high for the same period and achieving stable growth for 7
consecutive years.
Since the beginning of this year, Northwest
Oilfield has focused on increasing storage, production, and efficiency,

Working Principle and Application of Self operated Regulating Valve
Working principle of self operated regulating valve:
The operation of a self operated regulating valve is based on a basic principle: to use the energy of the process fluid to adjust the position of the valve. These valves integrate a self regulating mechanism that can respond to fluctuations in process variables such as pressure, temperature, or flow rate. This type o
Localization of thrust bearings for compressor units in Zhenhai Refining and Chemical Industry
Recently, the cracking gas compressor unit of the No. 1 ethylene cracking unit of Zhenhai Refining and Chemical Corporation achieved continuous and stable operation, marking the successful completion of the localization task of the thrust bearing of the compressor unit. This is the first time that the compressor thrust bearing of the large-scale cracking unit of Zhenhai Refining
