A high pressure tube is a tube that can withstand pressure. It is used to transport the liquid. There are many kinds of pipes, such as steel tubes, copper tubes, stainless steel tubes, and so on. High quality carbon structural steel and alloy structural steel high pressure pipe are mainly used for manufacturing steam boilers and pipes with high pressure and above pressure.
High pressure Steel Pipe and stainless steel seamless steel pipe, these boiler tubes work under high temperature and high pressure, and the pipe will be oxidized and corroded under the action of high temperature smoke and steam. Therefore, the steel pipe has high lasting strength, high oxidation resistance and good organization stability.
Steel number is: high quality carbon steel steel steel number 20G, 20MnG, 25MnG; alloy structural steel steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; rust resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high pressure pipe in addition to chemical composition and mechanical energy, to do water pressure test, to make expansion. Oral and flattening tests. The steel pipe is delivered in heat treatment state.
High pressure metal tubes have high lasting strength, high oxidation resistance and corrosion resistance, good tissue stability and sufficient strength, hardness, wear resistance and impact toughness.

Li Yuan pointed out that the construction of green mines requires the coordination and cooperation of governments at all levels, industry associations, and mining companies to work together. The first is to insist on government guidance and support. The second is to give play to the support role of the association and give full play to the association, communication, and bridge ties of the trade associations. Under the guidance of governments and land and resources management departments at all levels, the industry self-discipline was strengthened and the organization and various business support work in the construction of green mines was effectively carried out. The third is to play a dominant role and role in mining enterprises. Mining enterprises must proceed from actual conditions, do a good job in the development plan of green mines, and actively and steadily progress; they must strengthen organization and standardization management, take the use of resources, protect the environment, and the harmony of the community as the core of green mine construction, with scientific and technological innovations and mechanism innovations. As a basic guarantee, comprehensively promote all tasks.
Zhang Hongtao pointed out that in order to build green mines, it is necessary to cherish mineral resources intensively and efficiently use resources; secondly, to effectively protect the mining environment; and third, to care about the interests of the community.
During the conference, the China Mining Association held a signing ceremony for research and application of pilot projects for the reform of mining land using Shenhua Shenyan Coal Company and the China Land and Minerals Law Center. At the forum, companies such as Tongji Group, Shenhua Group, Chinalco Corporation, and Shougang Mining Company introduced practices and experiences in developing green mines and promoting green mining.
The high pressure pipe occupies an important position in the development of the steering pipe of the hydraulic power steering system.
In addition, the microstructure, grain size and decarburization layer of finished steel pipe also have certain requirements. Seamless pipes for geological drilling and oil drilling and control are used for drilling underground wells in order to ascertain the structure of underground strata, underground water, oil, natural gas and mineral resources.
The exploitation of oil and natural gas can not be separated from the drilling, and the geological drilling and controlling of the seamless steel pipe used for oil drilling is the main equipment of the drilling, which mainly includes core outer tube, core tube, casing, drill rod and so on.
Because the drilling pipe has to work deep into the depth of several kilometers, the working conditions are very complex, the drill rod is subjected to tensile, pressure, bending, torsional and unbalanced impact loads, and it is also worn by mud and rock. Therefore, the pipe must have enough strength, hardness, wear resistance and impact toughness, steel pipe. The use of steel "DZ" (Geological Chinese Pinyin head) is represented by a number of steel yield points. The commonly used steel numbers are DZ45 45MnB, 50Mn; DZ50 40Mn2, 40Mn2Si; DZ55 40Mn2Mo, 40MnVB; DZ60 40MnMoB.
The steel pipes are all delivered in heat treatment.
Petroleum cracking pipe: seamless tube for furnace tubes, heat exchanger tubes and pipes used in petroleum refineries. Commonly used high quality carbon steel (10, 20), alloy steel (12CrMo, 15CrMo), heat resistant steel (12Cr2Mo, 15Cr5Mo), stainless steel (1Cr18Ni9, 1Cr18Ni9Ti) manufacturing. In addition to the chemical composition and various mechanical properties, the steel pipe should also ensure water pressure, flattening, flaring and other tests, as well as surface quality and non-destructive testing. The steel pipe is delivered under heat treatment.
Stainless steel pipe: hot rolled stainless steel tubes of various stainless steel, cold rolled stainless steel pipes, widely used in oil, chemical equipment pipes and all kinds of stainless steel structures for various purposes. In addition to ensuring chemical composition and mechanical properties, all steel pipes used to withstand fluid pressure should be qualified for water pressure testing. All kinds of special steel pipe should be guaranteed according to the stipulations.
High pressure rubber tube has non-toxic, environmental, physiological inertia, UV resistance, ozone resistance, high temperature resistance (-80 to 300 degrees), high transparency, strong resilience, compression resistant permanent non deformation, oil resistance, stamping, acid and alkali resistance, abrasion resistance, refractory, voltage resistance, electrical conductivity and so on.
China Mining Circular Economy Forum held in 2010
From September 11th to December 12th, the 2010 China Mining Circular Economy Forum was held in Datong, Shanxi Province, with the theme of “resources comprehensive utilization and green mine constructionâ€. Li Yuan, deputy director of the China Mining Association, deputy director of the Population Resources and Environment Committee of the National Committee of the Chinese People's Political Consultative Conference, Liu Zemin, deputy director of the Population and Environment Committee of the National Committee of the Chinese People's Political Consultative Conference, and Zhang Hongtao, chief engineer of the Ministry of Land and Resources attended the meeting.
