Highly efficient compressors for natural gas pipelines
Polytropic efficiency up to
Number of stages: 1 - 5
Maximum working pressure up to 2250 psi / 155 bar
World class energy efficiency for world class economicsSiemens offers a wide range of pipeline compressors with a choice of axial intake or conventional horizontally opposed suction and discharge nozzles. All designs allow for easy access to compressor internals without the need to remove piping. With up to 91% polytropic efficiency, our pipeline compressors are second to none in the industry. Each compressor’s aerodynamic assembly is custom engineered to maximize efficiency and operating range.
Drives and Package Options
Our pipeline compressors are typically packaged with the driver and all auxiliary systems on a base frame for ease of handling and reduced site installation time. A comprehensive range of industrial and aeroderivative gas turbines from Siemens are available as drivers. Fixed and variable speed electric drive systems from Siemens can be alternatively offered as prime movers.

Service and Support
Siemens provides full installation and commissioning services, as well as comprehensive service support over the lifetime of your equipment, including routine maintenance and repair services, upgrades and retrofits, and condition monitoring. These services can be either provided on demand or as part of long-term service agreements. With our global network of service centers, experienced field service representatives and OEM spare parts we want to ensure that our customers get the most value out of their operating assets.
Digitalization / Data Analytics
Pipelines 4.0 is an integrated approach to the engineering, supply and life cycle optimization of pipeline assets to maximize their economic value.
The solution builds upon Siemens' extensive pipeline experience, product breadth and expertise in rotating equipment, electrification, automation and digitalization.
Key features include equipment and turnkey packages for pipeline stations, as well as data analytics, life cycle service and cyber security.
Stack Up the Layers
Radial impellers play an integral role in the performance and reliability of turbocompressors. The stresses placed on the impellers during operation are typically higher than those placed on any other component of the rotating assembly. As a result, even the smallest manufacturing defects can lead to (at best) inefficient operation and (at worst) total compressor failure.
