Although the range of valve products involved in oil and gas development and transportation has remained largely unchanged over the past 100 years, valve manufacturers have continually updated valve technology to actively respond to changes in the oil and gas industry market. If you want to stay ahead or not fall in the market, valve manufacturers must constantly update the design, manufacturing, service, and sales of valves and technologies. The fact is that oil companies are increasingly demanding valve manufacturers: on the basis of providing reasonable prices, advanced valve manufacturers must be good at solving the problems faced by oil companies, in the case of more harsh working conditions and stricter environmental requirements. Extend the performance of valve products and provide more service capabilities.

(1) The demand for oil and natural gas in the world market of metal sealing has grown rapidly. The footprint of developing crude oil has also traveled to every corner of the earth. The extraction of crude oil has put forward new requirements for equipment. For example, ultra-deep well technology presents the challenge of ultra-low temperature and ultra-high pressure for equipment. The extraction of super heavy crude oil is an optional option for profit, especially when crude oil reaches $30 per barrel. High concentrations of asphaltenes and other impurities now make it difficult to transport and process crude oil. Usually, the soft-sealed ball valve used on the oil pipeline can not meet the requirements of the working conditions. This requires the valve manufacturer to develop a metal-sealed ball valve and adapt to changes in temperature and pressure, even when transporting solid media (hydroxide, coke, etc.). To ensure absolute sealing. Metal sealing technology benefits from the development of surface coating technology. Valve manufacturers hope to use this technology to maintain market leadership and include spray technology in their development strategy. They are working with research institutes and universities to develop the next generation of “superhard” coatings.

(2) Anti-explosive decompression In 2002, American Petroleum Institute standard API 6D stipulated that valve products with design pressure higher than ASME Class 600 must be designed to prevent “explosive decompression”. Explosive decompression means that when the pressure in the valve drops rapidly, the CO 2 permeating in the seal due to the high pressure rapidly expands due to the pressure drop, causing the seal to smash and break during the valve closing process, thereby causing the valve to fail. An oil company first discovered the explosion and decompression of the valve on the deep sea platform. After the valve failed, the company had to stop working for several weeks to replace the valve, resulting in heavy losses. Since then, oil companies have required high-pressure valves from valve manufacturers to be equipped with an "explosive decompression" configuration. Soon, valve manufacturers quickly responded by developing anti-explosive decompression seals and anti-explosive decompression valves to meet demanding environmental requirements.

(3) The crude oil price of sulfur-containing crude oil has caused the refining company to focus on the sulfur-containing crude oil. The investment in the development of sulfur-containing crude oil market is lucrative, and there is also a price competitive advantage in the long-term supply contract. However, sulfur-containing crude oils contain corrosive media such as H 2 S, which poses new challenges to the corrosion resistance of equipment. Valve manufacturers can provide materials approved under ISO 15156, as well as test (according to ISO 15156) data to demonstrate corrosion resistance and long life of valve materials. End users will list these valve manufacturers as corrosion resistant valve suppliers. .

(4) Flirting emissions ISO15848 specifies the requirements for the design of the valve's fugitive emissions. The manufacturer has redesigned the packing and sealing arrangements of ordinary valves and special valves to meet the updated standards. However, the new standards are too general and too strict, so many oil companies have set their own emission standards. For example, many North American companies refer to the API 622 standard. The further improvement of the valve's fugitive emission standards requires the valve manufacturers, users and standard setters to cooperate with each other and learn from each other's experience.

(5) Advance wear and equipment fatigue are pursuing economic benefits, and many refining companies are overloaded. The result is an endless expansion of production equipment and retrofit systems. The company's expectations for equipment far exceed the original intention of the design, which requires valve manufacturers to take precautions and actively participate in the user's work, to avoid the adverse effects of unreasonable design of the production process on valve reliability, life and safety. For example, valves used in thermal circulation systems are prone to thermal fatigue of parts. Valve manufacturers with industrial process experience will arrange valves to reduce the possibility of problems.

(6) Preventive maintenance Oil companies require equipment maintenance cycles in order to ensure production. With the development of valve testing systems, 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 automated control provide data analysis systems that quantify valve operation and provide preventive maintenance time for valves.

(7) The automation of the refining process of the automatic actuator is the trend of the times, and the intermediate control technology has been developed for a long time. Valve manufacturers install automatic actuators on the valves to meet the requirements of automatic production control. Automated actuator technology has been greatly developed. On the other hand, manufacturers of production actuators also provide users with valve products with actuators installed. As a result, the trend of integration of actuators and valves poses a challenge to a single producer. After all, users want to find a company to solve problems more easily and avoid the phenomenon of smashing.

(8) Pipeline ball valve natural gas transportation pipeline engineering is a very large and potential market for valves. Monitoring of long-distance pipelines is very important. Some companies have developed smart devices that users can use to probe pipelines. For example, "smart pig" technology. This type of robot can detect wall thickness and even corrosion points. However, the detection device has a diameter requirement for the pipeline, so the diameter ball valve has become the first choice for the long-distance pipeline company. On the other hand, long-distance pipelines require the wall thickness of the valve 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 manager of the long-distance pipeline requires that the valve life purchased must be longer than the life of the pipeline itself.
