Town gas transmission pipeline, applicable to natural gas, liquefied petroleum gas, artificial gas Due to the difference in the physical properties of crude oil and natural gas, there are significant differences between oil and gas transmission pipelines, mainly as follows: ① Oil transmission pipelines need to consider the impact of changes in the starting and ending elevation on the liquid pressure in the pipe, while the impact of gas transmission pipelines is minimal. ②Gas pipeline at high pressure is conducive to energy saving, while the friction loss of oil pipeline is affected by the pressure is very small. ③When there is a booster station along the pipeline, the inlet pressure of the intermediate station is generally low, as long as it meets the requirements of airtight transport, while the gas compressor requires a certain ratio of discharge pressure to inlet pressure, such as centrifugal compressor is generally 1.2 to 2, reciprocating compressor is 3 to 7, that is, the intermediate station is required to have a high inlet pressure. At the end of 2003, China's gas pipelines had reached 16,539km.

Stable performance, high cost performance; smooth inner wall, low fluid resistance; easy to install, using hot-melt butt and electric fusion connection. Suitable working temperature -20-40℃, applicable working pressure 0.3-0.7mpa. technical guidance for installation is available.

(1) Natural gas transmission pipelines are usually single pipes, with few valves and reducers.City gas pipelines are mostly ring-shaped and branch-shaped, with valves, tees and condensate cylinders and other fittings densely packed, and pipe reducers are more common.

(2) Long-distance pipelines are usually built at the same time, with complete survey and design, construction supervision and completion acceptance procedures, and relatively balanced quality.

(3) Long-distance pipelines are usually laid in the field, and changes in the surrounding environment are usually smooth transitions that are easy to grasp, and the impact of stray currents is relatively small.The surrounding environment of city gas pipelines is complex, and changes in the environment are sometimes sudden, in addition, urban stray current interference is very common and serious.

(4) Long-distance pipelines and foreign gas pipelines have well-developed management systems, whose daily management focuses on cathodic protection, and rectification begins as soon as potential abnormalities are detected.
