Application area, metal-to-metal joints BIRKOSIT - Dichtungskitt ® BIRKOSIT - Dichtungskitt ® has been used for 50 years on Siemens turbines (product development 1952 with Siemens). Without the additional sealing of individual pressure areas using BIRKOSIT - Dichtungskitt ® the production imprecision or the distortion under loads are no longer evened out, which means that the turbine areas in the individual pressure areas become permeable under pressure. This means the turbine loses power, and can even lead to unplanned reconditioning. BIRKOSIT - Dichtungskitt ® is formulated to be practically inert in its standard applications in steam and gas turbines. It is, therefore, resistant to exposure to hot air, steam, water, light fuel oils and lubricants. By implication, it should be resistant to crude oil and natural gas.

Use of the product in the application area, metal-to-metal joints [compressors]
Centrifugal Compressor
Centrifugal compressors are extremely robust machines that can be built for the compression of
various gases.
The casing design determines whether the compressors are categorised as horizontally or vertically split, each
type having different attributes and application limits. The advantages and disadvantages of each and the
feasibility of using a particular compressor should be considered with regard to the application in question.
Centrifugal compressors are used in a wide range of industries:
Oil and gas industry (up-, mid- and downstream)
Air separation plants
Chemical industries & Petrochemicals
Iron & steel, mining
Paper industry.
Classification of Centrifugal Compressors According to Design
Pressure [bar] Intake volume flow [m³/h]
ut to 225 bar up to 700000 m³/hm
Axial Compressor
Axial Commpressors attain volume flows of 70,000 to 1,400,000 m³/h
and a maximum outlet pressure of 20 bar.
They demonstrate their high level of efficiency in a variety of
applications such as:
Air separation plants
Ammonia plants
Blast furnace blower
Wind tunnels
Coking plants
Nitric acid plants
Fluid Catalytic Cracking (FCC) plants
Gas liquefaction plants.
Isotherm Compressor
Isotherm compressors are single-shaft centrifugal compressors with integrated cooling. They
are suitable for process air with minimal energy consumption. Over 1,000 systems have been
produced, installed and commissioned to date.
Isotherm compressors are characterised by:
Low energy consumption
Low noise emissions
Reliability
Compact construction
Centrifugal compressor inline
Highly developed aerodynamics
Cooler bundle in the compressor casing.
There are three types of isotherm compressor:
RIKT: Centrifugal air compressor with volume flows up to 670,000 m³/h
ARI: Combination of axial/radial compressor for maximum flow volume
RIO: Process compressor for oxygen with minimal space requirements
Technical Data Pressure [bar] up to 18 Suction volume flow [m³/h] from 66,000 to approx. 700,000
