The impact of valve technology
Although hundreds of years of oil, gas development and transmission range of products covered by the valve is basically little changed, but the Valves manufacturer have continued to update the valve technology, and actively deal with oil and gas industry to market changes. If you want to stay ahead in the market or are not falling, the valve manufacturer will have to constantly update the valve design, manufacture, service, sales techniques and processes. The fact is that oil companies have become increasingly demanding multi-valve manufacturers: in providing a reasonable price, based on an advanced valve manufacturers must specializes in solving the problems faced by oil companies, in the work environment even worse, environmental protection and require more stringent conditions , the extension of valve performance, to provide more service capabilities.
(1) metal seal in the world market for oil, natural gas demand for rapid growth and development of crude oil footprint travels to every corner of the earth, crude oil extraction equipment proposed new requirements. For example, the ultra-deep well technology, the equipment made the challenge of ultra-low moderate high pressure. Extra-heavy crude oil extraction is profitable alternative projects, especially in crude oil reached 30 dollars per barrel. Now a high concentration of Asphaltene and other impurities on the transmission and processing of crude oil caused difficulties. Usually oil pipeline is used in soft-sealing valve can not meet the requirements of working conditions, and this requires the development of metal sealing ball valve manufacturer, and can adapt to temperature and pressure changes, or even in the transportation of solid media (hydroxide, coke, etc. ) is also guaranteed to be completely sealed. The metal seal technology, due to surface coating technology. Valve manufacturers want to use this technology to maintain market leadership, and to spray technology into development strategies, they and Research Institute, University, hoping to develop a next-generation "super-hard" coating.
(2) anti-"explosive decompression," in 2002, the American Petroleum Institute Standard API6D states: ASMEClass600 level higher than the design pressure valve product must be designed to prevent "explosive decompression." Explosive decompression valve refers to the pressure within the rapid decline, due to high pressure infiltration of CO2 in a sealed pressure decreased due to the rapid expansion in the valve closing process and create a sealed explosion skin and fracture, leading to valve failure phenomenon. An oil platform in the deep ocean for the first time found that the phenomenon of explosive decompression valve, valve failure after the company had ceased operations a few weeks to replace the valve, resulting losses. Since then, oil companies asked to provide a high-pressure valve manufacturers valve must be with the anti-"explosive decompression" configuration. Quickly, valve manufacturers to respond quickly to develop anti-"explosive decompression" seal and anti-"explosive decompression" valve in response to harsh environmental requirements.
(3) The corrosion of high sulfur crude oil price of crude oil refining companies to look at the making of the sour crude oil, the investment and development sulfur crude oil market lucrative in the long-term supply contracts are also competitively priced. However, H2S and other sulfur-containing corrosive crude oil medium, the corrosion resistance of the equipment presented new challenges. ISO15156 valve manufacturers can license the materials provided, but also provides test (according to ISO15156 requirements) data to prove that the valve materials, corrosion resistance and long life, end-user Bianba these valves include corrosion resistant valves manufacturer supplier list.
(4) Fugitive emissions from ISO15848 provides for Fugitive emissions from the valve design requirements, the manufacturer redesigned the general valve and special ball valves packing, seals arranged to meet the updated standards. However, the new standards are too general, too demanding, so there are many oil companies have developed their own emission standards, such as many North American companies are the light of API622 standards. Fugitive emissions from valves to further improve the standard of need for valve manufacturers, users, standard setters tripartite cooperation, learn from each experience, three common solutions.
(5) early fatigue wear and equipment for the pursuit of economic interests, and many oil refineries are running beyond its capacity. The result is endless production equipment and improvement of the system capacity increase. The expectations of business equipment far beyond the original intention of the design, which requires manufacturers to take precautions valves, active participation of the user's various items of work and to avoid an unreasonable design of the valve manufacturing process reliability, longevity and safety of adverse effects. For example, the application of heat in the circulatory system valve easily lead to parts thermal fatigue, with the valve manufacturer of industrial process experience, reasonable arrangements will be the valve, reducing the likelihood of the problem.
(6) Preventive maintenance of oil companies in order to ensure the production, the request for equipment maintenance cycles. With the valve test systems, electronic hardware, software, development, and the valve of the preventive maintenance has been by an intelligent concept into a reality. A small part of the master automation control valve manufacturers to provide data analysis system to quantify the valve operation to provide valve preventive maintenance time.
(7) automatically executing agency refining process automation is the trend, this intermediate control technology has been developed for a long period of time. Valve manufacturers install automatic valves on the implementing agencies in order to achieve automatic control of production requirements. Self-executing agency technology is great development. On the other hand, the production executive body of the manufacturers to provide users with installation of the executive body of the valve product. As a result, the executing agency and the trend toward integration of a single valve manufacturers poses a challenge, after all, users want to find a company to solve problems more easily, to avoid the phenomenon of wrangling.
(8) pipeline transport of natural gas pipeline project on the ball valve is a very large potential market. Pairs of long-distance pipeline monitoring is very important. Some companies have developed intelligent devices, the user can be used to detect pipeline. For example "smartpig" technology. This robot can detect wall thickness, and even corrosion points. However, there are detection devices on the pipeline diameter of the requirements, so diameter ball has become the preferred long-distance company's product pipeline. On the other hand, require long-distance pipeline wall thickness as thin valves, valve material has a high yield toughness, corrosion resistance, to meet the telescopic pipes, steering, changing demands of the local environment. The most important point is that managers of long-distance pipeline to buy the valve life must be longer than the life of its own pipeline.
