Current situation of natural gas compressor industry

The domestic natural gas compressor industry started relatively late and began to explore the new market of natural gas compressor at the end of last century. Natural gas compressor belongs to high-pressure ratio large industrial centrifugal compressor, while Shengu group occupies most of the domestic market share in the field of centrifugal compressor and basically monopolizes in the field of high-end technology, The annual total value of the domestic compressor market is less than 10 billion yuan, belonging to a small industry. The centrifugal compressor is a high-grade industrial customized product. Shangu group was the first three-line factory dispatched by Shengu group to support the construction. The two sides have made clear the main direction. Shangu group mainly focuses on axial compressors and occupies most of the domestic market share. Around 2015, due to the domestic adjustment of supply and demand structure, The axial flow machine market has shrunk seriously. Shangu group has vigorously developed the field of centrifuges and began to participate in the market competition of long-distance pipeline compressors.

In the natural gas compressor industry, it is called long-distance pipeline compressor. It is a centrifuge with relatively standard design specifications, and the model needs to be fixed. It was first driven by PetroChina's west to east gas transmission project. At that time, China did not have a company capable of production. All imported compressors, American GE, German Siemens, etc. were used in the construction of the West first line and part of the west second line. The sky high price equipment was provided on-site guidance. Under the guidance of the State Council's localization, the compressor of Shengu long-distance pipeline officially entered the field of vision. Around 2011, the 20MW long-distance pipeline compressor of Shengu group was successfully commissioned, and then successfully entered the west to east gas transmission project, ensuring that the lifeline of the country is in its own hands. After the entry of Shengu group, the price of foreign units has shrunk significantly and the price has been reduced by more than half. So far, foreign units have basically lost their advantages in the domestic market competition and gradually withdrew from the Chinese market. Later, Sinopec also began to vigorously develop long-distance natural gas transportation. Sinopec's new Guangdong Zhejiang pipeline and China Russia natural gas pipeline project basically established the position of Shengu group as the core supplier of long-distance natural gas pipeline compressor for heart equipment. So far, the state of completely grasping China's destiny of high-end centrifugal compressor from abroad has ended.

Shangu group participated in the supply of a long-distance pipeline compressor of Shangu group. It is said that the supply cycle is long, beyond the original delivery date, and the technology is not mature. In addition, there is no foreign enterprise with this technology. Due to the large gas flow and high pressure ratio, it is impossible to use reciprocating and other forms of compressor equipment for long-distance pipeline compressors, so there is no need to talk about it here. In addition, in the field of reciprocating compressors, blowers and fans, the equipment technology is relatively simple. Compared with large centrifuges, it basically belongs to a free competitive market, The large centrifugal compressor belongs to the oligopoly market, and its technology is difficult and accumulated.
