Special
Materials
With CPI’s pioneering development of their
Special Polymer Alloys™ which have been successfully
applied into valves, piston and rod sealing components
are widely acknowledged as the best available for
use in reciprocating compressors.
The
advent of CPI’s Special Polymer Alloys™
has enabled compressor operators to achieve longer
seal lives compared to other materials available
and has made possible changes to compressor design
which has significantly reduced operating costs.
CPI has developed a number of special materials
such as:
|
• CPI 184 - for use in most dry
gas non lube applications
•
CPI 188
- specifically for pure
dry Nitrogen and Inert gases
•
CPI 192
- for higher pressure
and temperature applications both
lube
and non lube
•
CPI 196 - for higher pressure
and temperature pure dry Nitrogen
applications
•
CPI 113 - for non lube oxygen
(ignition tested/approved)
•
CPI 124 - for higher duty non
lube air applications
•
CPI 111 - for higher duty non
lube air applications
•
CPI 100
- for use in low pressure lube and
non-lube applications

Pioneering non lubricated materials for the
PET industry
|
CPI’s
Special Polymer Alloys™ have particular problem
solving capabilities, enabling problems of seal
life to be easily solved in existing non lubricated
compressors, they can also be used to convert lubricated
compressors to non lubricated in ways that were
not possible with traditional filled ptfe materials.
The
CPI development programme of non metallic materials
encompasses not only piston rings, rider rings and
piston rod packings but also oil wiper packings
and compressor valves.
