· Beijing over-removed 391,000 yellow-label vehicles
The reporter learned from the Beijing Municipal Environmental Protection Bureau that the city had exceeded the national task of eliminating 391,000 yellow-label vehicles in advance, marking that the city lasted for six years and finally bid farewell to the "Yellow Label Vehicle Era" and became the first basic solution in the country. The yellow label car emits polluted cities. Next, the city will use the national I, the national II car and the heavy-duty diesel car as the main target of treatment, mainly based on the old cars before 2006.

The city has been focusing on the yellow label car since 2008. According to the Municipal Environmental Protection Bureau, at the end of November 2014, the city eliminated a total of 426,000 old vehicles, of which the government has allocated 975 million yuan of financial subsidies to provide subsidies for 227,000 old car owners. In the next step, the management of China I, China II and heavy diesel vehicles will become the focus. The city has 971,000 standard vehicles of the national level II and below (there are 391,000 vehicles in China and below, and 580,000 gasoline and diesel vehicles in China), accounting for 17.3% of the city's 5.6 million vehicles. The emissions account for about 30% of the total direct emissions of motor vehicles.
As for the public to question whether the motor vehicle is polluted, but the pollution of coal burning and industrial production is even worse, why do you always take the motor vehicle to open the knife? The relevant person in charge of the Municipal Environmental Protection Bureau explained that in fact, Beijing's governance of air pollution has always been a multi-pronged, coordinated emission reduction, not only to capture vehicle emissions, but also to burn coal, industry, dust, volatile organic compounds and other emissions, Including open-air barbecues, catering industry fume, and littering of leaf litter are also being rectified. These measures are taken in response to different sources of pollution. At this stage, the pollution pattern has changed. The source of pollution has involved all aspects of our production and life. The air pollution control has reached the stage of “not to be small and not to be goodâ€.
â— Accounting: How much pollution is taken by the yellow label car. According to the calculation by the Municipal Environmental Protection Bureau, the elimination of 426,000 old motor vehicles can reduce the emission of carbon monoxide, nitrogen oxides, hydrocarbons and particulate matter by 135,000 tons annually.
In the big cities of the world, although the oldest cars with the most serious pollution emissions account for only about 20% of the total, the emissions account for 50%-60% of the total emissions of motor vehicles.
Seamless steel pipes are usually made by hot rolling or cold rolling of low alloy structural steels such as 16Mn, 5MnV or 40Cr, 30CrMnSi, 45Mn2, 40MnB, etc., which are high quality carbon-bonded steels such as 10, 20, 30, 35, 45.
Seamless pipes made of low carbon steel such as 10 # and 20 # are mainly used for fluid conveying pipes. Seamless tubes made of 45, 40Cr and other medium carbon steels are used to manufacture mechanical parts, such as stress parts of automobiles and tractors.
