Compared with foreign countries, the technological level of China's petrochemical equipment still has a big gap: First, the development of petrochemical equipment cannot keep pace with the development of petrochemical process technology; second, the development of software technology for major equipment basically remains at the level of imitation, There are few proprietary technologies with independent intellectual property rights; third, equipment development cannot be specialized, standardized, and serialized; fourth, the reliability of the equipment still needs to be further improved; fifth, general equipment manufacturing capacity is excessive, and major equipment manufacturing capacity insufficient.
Technological innovation is not optimistic
"Eleventh Five-Year" China will usher in a new peak of petrochemical construction. China's petrochemical production scale will be 8 million to 12 million tons/year of refinery equipment, 800,000 to 1 million tons/year of ethylene equipment, and 600,000 to 1 million tons/year of PTA equipment. It is estimated that the petrochemical equipment market capacity will reach 30 billion yuan annually.
Recently, Zhu Sendi, vice president of the China Federation of Machinery Industry, introduced the development prospects of China's equipment manufacturing industry, saying that China's 2010 development goal is to enter the world's top 3 in the total economic output of the equipment manufacturing industry; in 2020, the long-term goal is to enter the world The ranks of the powerful manufacturing equipment manufacturers have become the world’s important equipment manufacturing and supply bases, with a major equipment domestic market share of 90%.
Faced with the trend of large-scale petrochemical major equipment and the gap between China's equipment manufacturing technology and foreign standards, Wang Tingjun, an old expert in China’s petrochemical major equipment industry, said that China’s petrochemical equipment manufacturing industry should consider long-term considerations and track the requirements of advanced technology and petrochemical industry development in the world. Accelerate the pace of technological innovation and increase investment in science and technology so as to comprehensively increase the competitiveness of enterprises in both domestic and foreign markets.
When maintaining vehicle tyres, one of the most important tasks is to ensure that the tyres are inflated correctly. However, for some drivers, this may be a challenging task, especially when their vehicle is difficult to reach the tire valve. This is where the metal tire valve expander is used.
The automobile metal tire valve extender is a small metal pipe connected to the tire valve, which allows you to inflate the tire without removing the wheel or fighting with the valve that is difficult to reach.
One of the most common reasons is that it is difficult to connect the air hose or pressure gauge because the valve stem is too short. This is where the metal tire valve expander is used. By connecting the extender to the valve stem, you can easily reach the valve and inflate the tire without any trouble.
