Cryogenic valves normally refer to valves with working temperature blow -110℃. It is widely used in LNG, LPG and other low temperature industry. Valves designed for cryogenic services, are specially prepared and designed to overcome these challenges. Appropriate component materials such as 304SS (CF8) and 316SS (CF8M) are normally used for body and trim, offering superior impact strength, and excellent corrosion resistance and heat loss properties. An extended bonnet and gas column design is also normally adopted to provide thermal insulation at the stem seal and stem packing area. At sufficient length, this design feature places the functionality of the stem seal in the vapor zone of the liquid media providing safe and continuous valve operation. A variety of body, trim, seat, and seal materials are available for use in cryogenic service. Customer specified options, such as body cavity vent hole, special extension lengths, and materials are also available upon request.

At the beginning of 2012, the "Pm2.5" from hot words to the NPC's important bill has always been the focus of public concern. Behind the discussion of "Pm2.5", it is even the "hidden worry" revealed by the Chinese people on the issue of environmental protection. Coincidentally, the International Consumer Day with the theme of “consumption and security†in 2012 also contained reflections on consumption and environmental protection. According to the Chinese Consumer Association’s interpretation of the theme, which includes “enhancing resource conservation and environmental protection, protecting environmental safety, and safeguarding the long-term interests of consumersâ€, this is not only related to the interests of consumers, but also to the public’s environmental issues. Hot discussion.
At present, after rapid industrialization in China, under the dual pressures of the international environment and domestic environmental protection, how to promote energy conservation and emission reduction and protect the environment has become a major issue for the entire society. Under such a big environment, it is worth thinking and paying attention to how to make the government, consumers, and industrial high-energy-consuming enterprises tripartitely cooperate to co-govern and gradually implement energy-saving and emission reduction.
Energy-saving and emission reduction is imminent
The government's "12th Five-Year Plan" report recently pointed out that the current situation of China's energy-saving emission reduction is not ideal. Statistics show that in the first three quarters of 2011, the six high-energy-consuming industries continued to show rapid growth, and industrial energy consumption increased significantly. The energy consumption per unit of GDP in the country only fell by 1.6%, which was a big gap from the target of 3.5% and 4% for the whole year. With the acceleration of industrialization and urbanization in China, the demand for industrial products in the society continues to grow, and the tasks of industrial transformation and upgrading and green development are still very arduous.
Moreover, as China's car ownership has broken 100 million, the large-scale increase in car ownership has also brought tremendous pressure on the environment, energy saving and emission reduction has become imminent, not only promoting the upgrading of automotive technology in power systems, emissions systems, etc. This also directly involves the large-scale technical upgrading and product structure adjustment of the automobile accessory industry. Among them, the lubricant industry, which is closely related to automobiles, is also facing a wave of product upgrades and technology upgrades. High-performance lubricant products are increasingly favored by consumers and become the focus of consumer concern and the choice of “consumption and safetyâ€. One ticket.
Lubricants industry sings upgrade theme
There is no doubt that the horn of the lubricants industry upgrade has already begun. Many lubricant companies have made efforts to promote product upgrades in order to comply with industry trends and energy-saving emission reduction needs, while a few more forward-looking and technical control of lubrication Oil companies are at the forefront of the industry, and their products have been ahead of the current emissions standards. Among them, the Jinjixing SN-standard steam engine oil released by Great Wall in August 2011 is a typical representative.
It is understood that the Great Wall launched Jinjixing J700U, J700F and J600F is its SN specifications of the series of products, as the world's highest specifications of the engine oil products, in terms of product performance and environmental protection than in the past have made great breakthroughs, with Higher fuel economy and fuel economy durability, and ensure the compatibility of engine oil and vehicle emission system components, can meet Euro VI and other higher level emission standards, and provide a match for the development trend of low-carbon and energy-saving in the automotive industry. lubricating oil.
High-quality lubrication for "consumption and safety" services
At present, China has become the second largest lubricant oil market in the world. It has become a hot spot for oil companies at home and abroad, and the competition is intensifying. How do lubricant brands such as Shell and Great Wall get a leading edge in the fierce market competition? Energy-saving emission reduction trend service? Li Liangyao, deputy general manager of Sinopec Lubricants company, broke through the mystery: "Lubricating oil market is a brand, there is no quality without a brand." Is based on the importance of quality awareness Recognizing that the Great Wall has spared no effort to improve the quality of its products, it not only has its basic advantages in the civilianization of its aerospace technology, but also has insight into the needs of customers, and has achieved the forward-looking advantages of technological R&D and product development in sync with the world, laying the foundation for Great Wall in China's lubricant industry. The leading edge.
It is understood that the Great Wall has served China’s space industry for more than 50 years and has 70% of the research and development strength of the domestic lubricant industry. This provides a solid foundation for Great Wall's civil use of lubricants, and it has achieved the reputation of “Great Space Quality†of the Great Wall and upholds aerospace. The attitude of perfection also makes the product 100% qualified to become the basic bottom line of the sense of quality of the Great Wall. On the other hand, Great Wall has cooperated with internationally renowned research institutes such as the Southwest Research Institute of the United States and well-known auto companies at home and abroad, and has continuously introduced lubricants that meet the highest international standards and international environmental standards. The company continues to make breakthroughs in product performance and environmental performance. Conform to the development trend of automotive technology, but also become a good helper for energy saving and emission reduction.
Nowadays, public demands for environmental protection and low-carbon environment are increasing. Lubricating oil industry and other industries should consider “energy conservation and environmental protection†as a factor in the pursuit of product quality, and provide consumers with the connotation of “consumption and safetyâ€. High quality products. This puts forward higher standards and requirements for many companies, and also reflects the profound significance of the corporate brand's contribution to consumers and society.
