Scope of Application of the Goods

Tubing: tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete
It is made to withstand the pressure generated from the extraction process
Tubing is manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes

Q:The rapid rise in the prices of petrochemical products and energy, which may have a greater impact on the following sectors of earnings?The rapid rise in the prices of petrochemical products and energy, which may have a greater impact on the following sectors of earnings?A. medical instruments and equipment manufacturingB. proprietary Chinese medicine manufacturingC. Chinese herbal medicine processingD. chemical pharmaceutical manufacturing
Dependence on petrochemical products is not large, traditional Chinese medicine and Chinese herbal medicine mainly as raw materials
Q:What are the courses? What is the difference between specialized research nuclear power, hydropower and so on? I hope not to copy the existing information on the Internet, I learned about the best seniors
Because of the gradual depletion of conventional energy resources, environmental and ecological destruction, in promoting energy science and technology, new energy (wind, solar, biomass, geothermal energy, ocean energy, hydrogen energy utilization etc.) and constantly improve the level of economy is gradually revealed, many countries and regions to develop the energy industry, but also to achieve an important way of circular economy and low carbon economy, the proportion increased year by year. The new energy science and engineering specialty is a strategic emerging industry undergraduate specialty which was established in 2011 to meet the new energy industry development trend in china.
Q:Firewood (dry) is what type of energy
It includes plants, animals and microorganisms. The concept of biomass includes all plants, microorganisms, animals, plants, microorganisms, and waste products
Q:Total energy consumption and total energy production
Any of the two secondary energy products produced by the conversion of various energy sources (including other non - energy products and associated products)
Q:And the world's oil futures and other energy futures prices related to China's domestic futures varieties which futures? Seek expert futures and futures experts cited. Thank you
Fourth: PP (polypropylene), plastic, PTA, as well as Zheng Chun (MA)! In addition to the oil products, such as soybean oil, palm oil.
Q:What is terminal energy consumption
3 the energy used as a material refers to the use of some of the energy does not constitute a product of the entity only play a supporting role in the consumption of such as washing gasoline diesel oil kerosene lubricating oil used in various equipment4 process energy refers to the process in the production process is not used as raw materials, nor as a fuel, power use of the process of energy use, such as the production of calcium carbide power, electrolytic powerThe terminal energy consumption is equal to the energy consumption of terminal energy
Q:State approved products called new energy foods
The difference between new resource food and health food:1 health food refers to food with specific health functions, and approval must also be clear that what has a health care function, and the need for a health care function marked and defined on the product packaging, the new food resource has one or more functions are not on the product introduction mark in detail.2 new resources of food and health food for the application of the crowd is different, the former applies to any population, while the latter is suitable for specific populations.
Q:I would like to ask you, China's electronic products have the use of energy classification, if so, what is the specific classification?
Level 4 indicates that the energy efficiency of the product is lower than the market average;Level 5 is the market access indicators, below the grade requirements of the product does not allow production and sales.
Q:At present, what are the main types of new energy vehicles?
What types of new energy vehicles?New energy vehicles, including fuel cell electric vehicle (FCEV), hybrid cars, hydrogen powered cars, pure electric vehicles (BEV, including solar cars) and other new energy (such as high energy storage, two cars of various types of products of ether).
Q:China's new energy situation? The biggest obstacle? What can be learned abroad?What is the most important countermeasure in our country?
(1) the basic purchase characteristics of target consumers(2) target consumers' evaluation of target areas and projects(3) analysis of the characteristics of target consumers' purchase of competing products(4) consumers' cognition and cognitive approach to target market
