Oil and gas industry to the impact of valve technology
 
Although a century of oil, natural gas development and distribution of products covered by the scope of the valve is basically no change, but the valve manufacturers have continued to update the valve technology, a positive response to oil and gas industry to market changes. If you want to stay ahead in the market or not to be closed, valve manufacturers valve will be continuously updated the design, manufacture, service, sales techniques and processes. The fact is that oil companies on the requirements of the valve more and more: to provide the basis of a reasonable price, advanced valve manufacturers must be good at to solve the problems faced by oil companies, in the working environment even worse, more stringent environmental requirements of the situation , the extension of the valve performance, the ability to provide more services.
(1) metal seal on the world market oil, natural gas demand for the rapid growth in the footsteps of the development of crude oil has also traveled to every corner of the earth, crude oil extraction on new demands on equipment. For example, the ultra-deep technologies on equipment made the challenge of ultra-high pressure ultra-low-moderate. Extraction of crude overweight is optional profitable projects, especially in the crude oil reached 30 dollars a barrel. High concentrations of asphalt now, as well as other impurities Triazene for crude oil transportation and processing difficult. Oil is usually used in the soft-seal ball valve can not meet the requirements of the condition, which requires the development of metal seal valve manufacturers ball valve, and can adapt to temperature, pressure changes, even in the delivery of solid media (hydroxide, coke, etc. ) when it must make sure that absolutely sealed. Metal sealing technology to benefit from the development of surface coating technology. Valve manufacturers want to use this technology to maintain market leadership, and the inclusion of spray technology development strategies, and their research institutes, universities, hopes to develop the next generation of "super hard" coating.
(2) anti-"explosive decompression" In 2002, the American Petroleum Institute standard API 6D provides that: the design pressure of ASME Class 600 higher than the level of valve products must be designed to prevent "explosive decompression." Explosive decompression of the pressure valve means rapid decline, due to infiltration of high pressure in a sealed CO 2 due to the rapid expansion of lower pressure in the valve caused the closure of the process of sealing auriventris and fracture, resulting in the phenomenon of valve failure . An oil platform in the deep valve the first time found that the phenomenon of explosive decompression, the valve immediately after the expiration of the company had ceased operations a few weeks to replace the valve, resulting in heavy losses. From then on, the oil companies asked to provide the high-pressure valve manufacturers with anti-valve must be "explosive decompression" configuration. Soon, valve manufacturers to respond quickly to the development of anti-"explosive decompression" sealed and anti-"explosive decompression" valve in response to harsh environmental requirements.
(3) corrosion of the high sulfur content crude oil prices make oil refining companies to look on the sulfur content of crude oil, the sulfur content of the crude oil market investing in the development of lucrative, long-term supply contract prices are also competitive advantages. But the content of crude oil contains H 2 S and other corrosive medium, corrosion resistance of equipment to the new challenges. Valve manufacturer can provide the materials license ISO15156 requirements, but also provide the pilot (according to the provisions of ISO15156) data to prove that the corrosion resistance of the valve materials and long-life, end-user then the manufacturer of these valves to include corrosion-resistant valve list of suppliers.
(4) emissions?ɒݰrovides for ISO15848 emissions?ɒݶalve design, manufacturers redesigned the general valve and special valve packing, sealing order to meet the updated standard. However, the new standard is too general, the requirements are too strict, so there are many oil companies to develop its own emission standards, for example, many North American companies with reference to API 622 standards. Valve?ɒݯf emission standards to further improve the needs of the valve manufacturers, users, standard-setters tripartite cooperation, learn from each other experience, the three parties together to resolve.
(5) in advance of fatigue wear and equipment for the pursuit of economic interests, many refineries are running overload. The result is endless capacity production equipment and improvement of the system. Business-to-equipment far exceeded the expectations of the original design, which requires manufacturers to take precautions valves, active participation of all users of the work of the production process to avoid an unreasonable design of the valve reliability, longevity and security of the adverse effects. For example, the application of heat in the circulatory system caused by parts of the valve easier to thermal fatigue, with experience in industrial processes valve valve manufacturer will make reasonable arrangements to reduce the possibility of problems.
(6) preventive maintenance of oil companies in order to ensure the production, arrangement for equipment maintenance cycle. With the valve test systems, electronic hardware, software development, preventive maintenance valves has been the concept of intelligence into a reality. Proficient in a small portion of the valve automation and control manufacturers to provide data analysis system to quantify the valve operation to provide time for preventive maintenance valve.
(7) self-executing agencies refining process automation is the trend, which has been the middle of the development of control technology for a long period of time. Valve manufacturers to install an automatic valve on executing agencies in order to achieve automatic control of production requirements. Self-executing agencies to develop great technology. On the other hand, the production of the executing agency of the manufacturers to provide users with the installation of the executive body of the valve products. Thus, the executive body of the trend of integration and the valve manufacturer for the formation of a single challenge, after all, a business user wants to find it easier to solve the problem in order to avoid the phenomenon of passing.
(8) natural gas transport pipeline ball valve on the valve for the pipeline project is a very large potential market. Of long-distance pipeline monitoring is very important. It has developed a smart device, the user can be used for detection of the pipeline. For example, "smart pig" technology. This robot can detect the thickness of the wall, and even corrosion points. Detection device on the pipeline but there is the request path, so the ball valve has become the path of long-distance company of choice for pipeline products. On the other hand, long-distance pipeline as far as possible the requirements of thin wall thickness of the valve, the valve material has a high yield toughness, corrosion resistance, to meet the telescopic pipes, steering, changing requirements of the local environment. The most important point is that managers of long-distance pipeline valves require the purchase of life must be longer than the life of the pipeline itself.
