pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or treatment plants to urban gas distribution bases or users of industrial enterprises are also called gas transmission pipelines. Using natural gas pipeline to transport natural gas is the only way to transport natural gas in large quantities on land. In the total length of pipelines in the world, natural gas pipelines account for about half. What about the price and characteristics of pipeline natural gas? If we are interested, let's take a look at the specific content.

pipeline natural gas price:

1. Beijing, 2.28 yuan/m3;

2. Shijiazhuang, 2.41 yuan/m3;

3. Tangshan, 2.15 yuan/m3;

4. Xingtai City, 2.41 yuan/cubic meter;

5. Taiyuan, 2.26 yuan/cubic meter;

6. Datong, 2.11 yuan/m3;

7. Yuncheng, 2.31 yuan/m3;

8. Hohhot, 1.82 yuan/m3;

9. Baotou City, 1.82 yuan/m3;

11. Wuhai city, 2.18 yuan/m3;

characteristics of pipeline natural gas:

1. pipeline structure. The gas pipeline is assembled by connecting a single pipe one by one. Modern gas gathering pipelines and gas transmission pipelines are made of steel pipes connected by electric welding. There are many kinds of steel pipes, such as seamless pipe, spiral seam pipe and straight seam pipe. Seamless pipe is suitable for pipes with a diameter below 529 mm, and spiral seam pipe and straight seam pipe are suitable for large-diameter pipes. The pipe cross-sectional structure of gathering and transportation pipeline is disordered as internal coating-steel pipe-external insulation layer-thermal insulation (cold insulation) layer; Simply speaking, only the steel pipe and the outer insulation layer, while the inner wall coating and heat preservation (cold preservation) layer are determined according to the gas transmission technology.

2. pipeline data. Steel pipe is the main data of pipeline. Natural gas transportation steel pipe is a special metallurgical commodity formed by deep processing of plate (strip). The arrangement and shape of pipeline steel, because of the different technology, there are certain differences in pipeline steel produced by various manufacturers. In 1961s, X52 steel grade was usually selected, X61 and X65 steel grades were selected in 1971s, and X71 steel was mainly used in 1981s and 1991s. X81 steel has been selected for gas pipelines in some foreign countries. With the continuous development of pipeline steel research, Canada and other countries have laid experimental sections of X11 and X121 pipeline steels. For the first time, China used X81 pipeline steel in the 7.71km experimental section in the pipeline project of Ji-Ning tie line. X81 grade pipeline steel with a diameter of 1219mm was selected for the 4843km long trunk pipeline of the Second West-East Gas Transmission Line, and the gas transmission pressure was increased to 1.2 MPa. Generally speaking, X81 steel is ferrite and bainite dual-phase arrangement, X11 pipeline steel is bainite arrangement, and X121 pipeline steel is ultra-low carbon bainite and martensite. For natural gas pipeline pipes, strength, toughness and weldability are three basic quality control indicators.

3. pipeline characteristics. The gas pipeline system is a continuous closed transportation system. From transportation, storage to user's use, natural gas is under pressure, because the proportion of natural gas transported is small, and the influence of static head is far less than that of liquid. When the design height difference is less than 211 meters, the static head can be ignored, and the line is simply not restricted by longitudinal topography.

xiaobian tells us so much about the price and characteristics of pipeline natural gas today. Therefore, people in the industry should advise our owners that there is no water hammer damage to pipeline natural gas.
