Valve manufacturers constantly update valve technology, extend the performance of valve products, and provide more service capabilities

although the range of valve products involved in the development and transmission of oil and natural gas has basically not changed in the past century, valve manufacturers have constantly updated valve technology, and actively respond to the changes in the oil and natural gas industry market. If they want to remain ahead of the market or not be left behind, valve manufacturers should constantly update valves

although the range of valve products involved in the development and transmission of oil and natural gas has basically not changed in the past century, valve manufacturers have been constantly updating valve technology and actively responding to the changes in the oil and natural gas industry market. If they want to remain ahead of the market or not be left behind, valve manufacturers should constantly update the technology and process of valve design, manufacturing, service and sales of researchers from Dow Shanghai R & D center and teams from other developed countries. The fact is that oil companies have more and more requirements for valve manufacturers: on the basis of providing reasonable prices, advanced valve manufacturers must be good at solving the problems faced by oil companies, and extend the performance of valve products and provide more service capabilities under the condition of worse working environment and stricter environmental protection requirements

(1) the demand for oil and natural gas in the world market of metal seals is growing rapidly, and the footprint of developing crude oil has also traveled to every corner of the earth. The extraction of crude oil puts forward new requirements for equipment. For example, ultra deep well technology poses challenges of ultra-low temperature and ultra-high pressure to equipment. The extraction of ultra heavy crude oil is a profitable option, especially when the global market reached us2billion yuan in 2010 and the crude oil reached US $30 per barrel. At present, high concentration of asphaltene and other impurities have caused difficulties in the transportation and processing of crude oil. Usually, the soft seal ball valve used in oil pipeline can not meet the requirements of working conditions, which requires the valve manufacturer to develop metal seal ball valve, which can adapt to the changes of temperature and pressure, and even ensure absolute sealing when transporting solid media (hydroxide, coke, etc.). Metal sealing technology benefits from the development of surface spraying technology. Valve manufacturers hope to use this technology to maintain a leading position in the market and include spraying technology in their development strategy. They cooperate with research institutes and universities to develop the next generation of "super hard" coatings

(2) anti "explosion decompression" in 2002, API standard 6D stipulated that valve products with a design pressure higher than ASME class 600 must be designed to prevent "explosion decompression". Explosion decompression refers to the phenomenon that when the pressure in the valve drops rapidly, the CO 2 penetrating into the seal due to the high pressure expands rapidly due to the pressure drop, causing the seal to burst and fracture during the valve closing process, resulting in the failure of the valve. An oil company found the valve explosion decompression phenomenon for the first time on the deep-sea platform. After the valve failed, the company had to stop operation and replace the valve for several weeks, resulting in heavy losses. Since then, oil companies have required that the high-pressure valves provided by valve manufacturers must be equipped with anti "explosion and pressure reduction" configuration. Soon, valve manufacturers responded quickly and developed anti "explosion decompression" seals and anti "explosion decompression" valves to meet stringent environmental requirements

(3) the corrosion of sour crude oil and the rising crude oil price make refining companies focus on sour crude oil. The investment in the development of sour crude oil market is profitable, and it also has a price competitive advantage while attracting investment in long-term supply contracts. However, sour crude oil contains corrosive media such as H2S, which poses new challenges to the corrosion resistance of equipment. Valve manufacturers can provide materials permitted by iso15156, and also provide test data (according to iso15156) to prove the corrosion resistance and long life of valve materials. The end user will list these valve manufacturers in the list of corrosion-resistant valve suppliers

(4) fugitive emissions iso15848 specifies the requirements for the design of valve fugitive emissions. The manufacturer redesigned the packing and sealing arrangement of ordinary valves and special valves to adapt to the updated standards. However, the new standard is too general and strict, so many oil companies have formulated their own emission standards. For example, many North American companies refer to the provisions of API 622 standard. The further improvement of the valve fugitive emission standard requires the cooperation of valve manufacturers, users and standard makers to learn from each other's experience of turning the swing rod clockwise at angle a, and the three parties will work together to solve it

(5) in order to pursue economic benefits, many oil refining enterprises are overloaded. The result is endless expansion of production equipment and transformation of systems. The expectation of the enterprise for the equipment greatly exceeds the original intention of the design, which requires the valve manufacturer to take precautions and actively participate in the work of users to avoid the adverse effects of unreasonable design in the production process on the reliability, service life and safety of the valve. For example, valves used in thermal cycle systems are easy to cause thermal fatigue of parts. Valve manufacturers with industrial process experience will reasonably arrange valves to reduce the possibility of problems

(6) preventive maintenance in order to ensure production, oil enterprises require to arrange equipment maintenance cycles. With the development of valve test system, electronic hardware and software, the preventive maintenance of valves has changed from an intelligent concept to reality. A small number of valve manufacturers who are proficient in automatic control provide data analysis systems to quantify the valve operation process and provide preventive maintenance time for valves

(7) automatic actuator oil refining process automation is the general trend, and the control technology in the middle has developed for a long time. The valve manufacturer shall install automatic actuator on the valve to meet the requirements of automatic control production. The technology of automatic actuator has been greatly developed. On the other hand, manufacturers that produce actuators also provide users with valve products installed with actuators. Therefore, the trend of the integration of actuator and valve poses a challenge to a single manufacturer. After all, users want to find an enterprise to solve the problem more easily and avoid wrangling

(8) pipeline ball valve natural gas transportation pipeline engineering is a very large and potential market for valves. The monitoring of long-distance pipelines is very important. Some companies have developed intelligent devices that users can use to detect pipelines. For example, "smart pig" technology. This robot can detect the thickness of the pipe wall and even corrosion spots. However, the detection device has requirements for the diameter of the pipeline, so the diameter ball valve has become the preferred product of long-distance pipeline companies. On the other hand, the long-distance pipeline requires the valve wall thickness to be as thin as possible, and the valve material has high yield toughness and corrosion resistance to meet the requirements of pipeline expansion, steering and regional environmental changes. The most important point is that the managers of long-distance pipelines require that the service life of the purchased valves must be longer than that of the pipeline itself
