Phase 6 emissions standards are no longer using the standard motor vehicles

Clean Air Act of 2013-2013 plan, strive to implement phase 6 motor vehicle emission standards in 2016. To this, the 90 degree pipe fitting long radius elbow municipal environmental protection bureau commissioner of motor vehicle Li Kunsheng said: "now the fifth stage of the discharge standards, the standards of gasoline vehicles is nitrogen oxides 60 Long Radius 90 Deg carbon seamless elbow milligrams per kilometer, the index to the six standard is still 60 mg, and no strict standard of gasoline vehicles, so in the sixth stage we want to follow California's standards."

Pollution in Beijing, he explained, in some cases is more severe than California, California, as the control motor vehicle the SCH160 Nominal Wall Thickness welded Pipe most stringent region, its standard than the 6 strictly, this is the purpose of the environmental protection bureau to the adoption of California standards.Li Kunsheng stressed: "the sixth stage A106 High quality carbon structural steel tube standard application to difficulty is very big, because involves the conversion standard system, all the detection method, the regulation method of adjustment, involved in automobile production enterprises and related departments, the relevant authorities of the country."

Li Kunsheng mentioned at the same time, the average pollution levels in Beijing is 90 micrograms to 100 micrograms, national standard is 35 micrograms, even under the clean air action plan, PM2.5 in Beijing in 2017 dropped to 60 micrograms is not up to standard.We have learned, Beijing air pollution control is mainly to reduce the sulfur content, with the reduction of sulfur content such as nitrogen oxides and volatile organic compounds directly improve PM2.5 concentrations of material control, will become the focus of the air pollution control.

"At the moment of Beijing in 5 oil standard, sulfur content standards and Europe, but olefins, aromatics and other volatile organic compounds in fact no strict Europe, Europe about the environmental protection standard of the product in strict, at least one times more than our strict standards." Li Kunsheng said, because can directly reduce the PM2.5 levels, improve the photochemical pollution, volatile organic compounds of these environmental protection index and yan can directly improve the environment quality.
