Natural gas pipeline compressor is the "heart" of natural gas pipeline, its function is to compress the natural gas to make it pressurised to provide the required pressure for pipeline transmission, and it is the key equipment to ensure the reliable operation of natural gas pipeline.
According to the data released by the National Energy Administration, in 2023, the total mileage of long-distance natural gas pipelines in China will be 124,000 kilometres, an increase of more than 4,000 kilometres compared with the previous year; natural gas accounted for 8.5% of the total primary energy consumption, an increase of 0.1 percentage points compared with the previous year.China's natural gas infrastructure construction as well as consumption demand shows a rising trend, promoting natural gas pipeline compressor market space.
According to the "2024-2028 Natural Gas Pipeline Compressor Industry Deep Market Research and Investment Strategy Recommendation Report" released by Xinsiye Industry Research Centre, the performance of natural gas pipeline compressor directly affects the efficiency of natural gas transmission, and if a failure occurs, it will lead to a decline in the safety of natural gas transmission, and even lead to serious accidents, and cause pollution to the ecological environment.Natural gas pipeline compressors have high requirements in structural design, manufacturing technology, material selection, sealing performance and other aspects.Globally, the leading natural gas pipeline compressor development manufacturers are mainly GE, Siemens and so on.
In the early days, China's natural gas pipeline compressor demand relies on imports. 2012, the second line of the West-East gas pipeline project, domestic compressors began to be applied in the construction of natural gas pipelines. 2016, the Shaanxi-Beijing four line project, domestic high-power electric drive compressors are applied.After more than ten years of development, China's natural gas pipeline compressor independent research and development and production strength continues to progress.
As of the end of July 2024, according to the national pipeline network group western pipeline limited liability company news, located in the west-east gas transmission two or three lines of the Yandun operation area of the three three sets of home-made fuel-driven compressor sets, the total operating time exceeded 100,000 hours, performance and reliability has been verified.
West-East Natural Gas Pipeline project is fully completed, the total length of the pipeline will reach about 3340 kilometres, long distance has become the development trend of natural gas pipeline.In order to improve the transmission efficiency and save the transmission cost, large diameter and high pressure natural gas pipelines are attracting attention.In this context, the performance and quality requirements of natural gas pipeline compressors continue to improve.
China's new version of the "Industrial Structure Adjustment Guidance Catalogue (2024 this year)" encourages the development of 18MW and above integrated compressor sets, 1200 mm diameter and above natural gas pipeline supporting compressors, gas turbines, valves and other key equipment.
Xinsiye industry analysts said that before 2024, China's natural gas pipeline compressor part of the core component demand is still dependent on imports. 2024 July, the national pipeline network and Dongfang Electric jointly developed the first 20MW-class fully localised natural gas pipeline electric drive centrifugal compressor sets, through the China Machinery Industry Federation appraisal.China's natural gas pipeline compressor market space, independent research and development strength is still progressing, the industry has broad prospects for development.
