Scope

GB/T 44986-2024 is the English-translated version of 天然气输送装置用透平压缩机.

GB/T 44986-2024 is the Chinese national standard covering the single-shaft centrifugal compressor that pushes gas along a land pipeline — the mechanical structure and the rotor dynamics, the aerodynamic performance and the calibration test that proves it, the materials, the painting, the auxiliary equipment and the automatic control and remote monitoring, the noise, the factory and on-site inspection, and the efficiency correction for seal degradation, which is what the machine loses as it runs. Axial flow and integrally geared machines are outside it, and so is anything but a single shaft. First edition, under the China Machinery Industry Federation. In force from 28 November 2024. Issued on 28 November 2024, it has been in force since 28 November 2024.
