On September 28, China Power Investment Corporation announced the landmark achievement of China's third-generation nuclear independence -- China's independent nuclear power technology brand and the world's advanced third-generation nuclear power model "Guohe No.1" in Shanghai. A year ago in September 2019, the State Council Information Office of China's first white paper on nuclear safety - white paper points out that China's nuclear safety, formed a complete system of nuclear industry, China's nuclear cause for energy security, protect the ecological environment, improving people's living standards, promote economic made important contributions to the development of high quality are also out of a nuclear safety road with Chinese characteristics. Third and fourth generatio

Corrosion has long been one of the most troublesome hazards of chemical equipment. A slight mistake can damage the equipment, or even cause accidents or disasters.According to relevant statistics, about 60% of the destruction of chemical equipment is caused by corrosion, so in the selection of chemical valve should first pay attention to the scientific nature of material.There is usually a misunderstanding, that stainless steel is "universal material", no matter what medium and environmental conditions hold out the stainless steel valve, this is a great mistake. Chemical valve material should be based on the different media, specific analysis of specific problems, not one size fits all.The following for some common chemical media to talk about the selection of

The outer surface of the valve should be painted out of the factory, the paint layer should be durable, beautiful rules, and ensure that the mark is clear. 1, valve products according to the body material to identify the paint, the color according to the table Body material Gray cast iron, malleable cast iron Nodular cast iron Carbon steel Acid resistant steel, stainless steel Alloy steel Identify paint color Black Silver Medium grey Sky blue Medium blue Note: acid resistant steel and stainless steel are not allowed to be painted, and copper alloy is not allowed to be painted

Domestic VS imported valve, how will you choose?As the saying goes, "the moon is bright at home," but now more and more people admire foreign imports.In the industrial sector, the trend is slowly spreading.Just say a common valve, same material, same function, the price of imported goods can be multiplied several times.Imported valve products in the price set their own unique style, but even if expensive, people still flock to. Is the inlet valve really that good?Where is the gap between domestic valve and imported valve?How can we close these gaps? The term "imported goods" refers to the products that are imported in their original packaging. From research and development to production, they are entirely in the place of origin of foreign countries, and foreign standards are

The National Energy Administration recently issued the guidelines for Energy Work in 2020 (hereinafter referred to as the Guidelines).The Opinions emphasized that multiple measures should be taken simultaneously to enhance the capacity of oil and gas security.Among them, "increase oil and gas exploration and development efforts" is listed as the first task."Why the emphasis on oil and gas exploration when oil prices are so low and you can buy oil abroad?"In the face of public doubts, Jin Zhijun, director of the State Key Laboratory of Shale Oil and Gas Enrichment and Effective Exploitation and an academician of the Chinese Academy of Sciences, told China Science Daily that oil and gas, like food and water, have become human necessities and strategic materials related to national securit

Fluorine plastic anticorrosive valve in the petroleum, chemical industry, medicine, metallurgy, electric power industries in contact with acid and alkali of strong corrosive medium, such as device has been widely used, but on how to choose good, with good lining fluorine plastic valves, according to our customers for many years field application experience, transform fluorine plastic anti-corrosion valve selection to medium temperature, pressure, pressure used several conditions following note rubber lining valves: Temperature of medium used for fluorine-lined plastic valves Lined with fluorine plastic valve, the use of fluorine plastic is F46(FEP), the use of the medium temperature can not exceed 150℃(medium temperature short time to 150℃, long time use temperature
