Product Description:

Product Description:

Casing is a wide range pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore
It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing, to allow drilling fluid to circulate, and extraction to take place
Steel casing pipes have smooth wall and minimum yield strength of 35,000psi
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:Energy consumption classification of electronic products in China
Level 2 means comparison;Level 3 indicates that the energy efficiency of the product is the average level of the Chinese market;
Q:What is the energy consumption per unit product
Definition: refers to the amount of energy consumed per unit of production, mainly has the following three kinds: (1) the comprehensive energy consumption per unit of product yield, refers to the number of all kinds of energy can produce average actual consumption, comprehensive energy consumption and corresponding product yield ratio.
Q:Rapid rise in petrochemical products and energy prices
Dependence on petrochemical products is not large, traditional Chinese medicine and Chinese herbal medicine mainly as raw materials
Q:What are the tax policies for renewable energy companies?
The national development and Reform Commission had issued the "renewable energy and long-term development plan" put forward, to 2020 the proportion of renewable energy in the energy structure to reach 16%, the proportion is still less than 1%. plan to increase financial input, the implementation of preferential tax policies "set down as a principle of the development and utilization of renewable energy.
Q:What is the cost effectiveness ratio of energy management in energy quality?
I guess what you are saying is the "efficiency" in the international energy standard
Q:What is the comprehensive calculation of energy production?
In order to comprehensively reflect the total energy production, various energy products must be calculated according to the different calorific value of the common conversion standards. In China, the standard coal is calculated, and the calorific value per kilogram of standard coal is 7 million.
Q:What are the needs and pain points of new energy vehicles in insurance products and related services
Insurance, new energy vehicles mainly insurance premium, significantly higher than that of the traditional models, the difference between the minimum 2000 yuan, up to more than 4700 yuan, even taking into account the new energy automobile owners is not high on daochengjian demand, do not calculate daochengjian, the difference between the minimum is close to 800 yuan, while the highest is more than 3200 yuan. Among them, the vehicle damage insurance costs higher in property losses, which is directly related to the purchase price of the new car. Only car damage insurance, the cost of new energy vehicles is higher than the insurance premium of more than 1000 yuan, it can be said that the high cost of insurance directly increases the cost of the annual use of consumers.
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
What you say should be a new resource food?In China, the newly developed, newly discovered, the introduction of no eating habits, in line with the basic requirements of food, non-toxic harmless to the human body, said the new resources of food.
Q:What are the economic operating standards for energy equipment and systems?
Strengthen supervision and inspection, to be the focus of inspection on resource consumption, pollutant emissions, comprehensive utilization of resources, the problems found in the inspection should take effective measures to urge enterprises and relevant units timely rectification, to realize the transformation of growth by high consumption, high pollution of the extensive economic growth mode to a resource-saving mode as soon as possible. 2, the formation of a resource-saving national economic system firmly establish people-oriented Scientific Outlook on Development, change the overdraft resources for development mode, path and mode transformation of economic development, to reverse the "high input, high consumption and crude mode of economic growth on high emissions, lack of coordination, difficult cycle, low efficiency, and gradually establish a resource-saving industries system and consumption system. To form a section, saving water and energy as the center of the agricultural system as soon as possible, the emphasis on efficiency, saving time and energy, raw materials, industrial system, scientific planning, good design, land saving, material saving, excellent quality of the basic system construction, saving time and energy, transportation system efficiency, moderate consumption thrift, life service system and save resource consumption, resource construction from the distribution of production and circulation, to save organic consumption in all sectors are interdependent and mutually restrict the overall strategic.
