Efficient, dependable and off the shelf
Pre-engineered gas-turbine driven pipeline compressor packages
Answers for energy.
Siemens Pipeline Compressor Packages
Siemens Pipeline Compressor Packages
are pre-engineered gas turbine compressor packages for pipeline applications.
These combine our standard ranges
of Siemens Gas Turbines (SGT TM) and
Siemens Turbocompressors (STC TM)
optimized to provide you with the best
technical and cost efficient solution
for your transmission and distribution
needs. The compressors cover a flow
range of 5,000 – 38,000 actual m3 / hr
(3,000 – 22,500 ACFM) with pressure
ratios up to 2.0.
Gas turbines with powers up to 13 MW
(ISO) offer the best efficiency in their
class with Siemens world beating dry
low emissions or standard combustion
systems.
Siemens Pipeline Compressor Packages
come with a range of pre-engineered
standard options to meet customerspecific
requirements.

Siemens Pipeline Compressor Packages
are available in three sizes based upon
the SGT-100, SGT-200 and the SGT-400
gas turbines.
Compressors are matched to the gas
conditions and the gas turbine speed to
provide optimum performance.
Selections can be focused on customerspecific requirements such as maximum
efficiency or maximum range or other
operating parameters.
