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
Therefore, the following factors should be considered when selecting valve sealing surface materials:
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
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
Shengli Oilfield's oil and gas production in the first 7 months exceeded the plan
Since the beginning of this year, Shengli Oilfield has consolidated its resource foundation, strengthened efficiency development, and continuously promoted the increase of reserves, production, and cost reduction. In the first seven months, it produced 13.5639 million tons of crude oil and 500 million cubic meters of natural gas, both exceeding the planned operation.
Common faults and troubleshooting methods of ball valves
Ball valve is a commonly used control valve in industrial pipelines, which has advantages such as simple structure, small flow resistance, and good sealing performance. However, during use, ball valves may also experience some common malfunctions, such as valve jamming, leakage, and leakage. Below, we will introduce common faults and troubleshooting methods for ball valves.
Due to some similarities in appearance between globe valves and gate valves, as well as their ability to cut off in pipelines, many circle members who do not have much contact with valves may confuse the two. In fact, if carefully observed, the difference between globe valves and gate valves is quite significant.
Firstly, in terms of valve structure, the gate valve can rely on m
Definition and difference of safety valve and relief valve
Safety relief valve (safety relief valve), also known as safety relief valve an automatic pressure relief device driven by medium pressure. According to the use of different occasions can be used as a safety valve or a relief valve.
In Japan, for example, to the safety valve and relief valve to make a clear definition of relatively few, generally used as a boiler
