To meet the varied sealing and piston support requirements of
Reciprocating Compressors, CVE Manufactures a wide variety of
Piston and Rider Rings up to 42" diameter. These rings are
offered in a broad range of materials to suit the specific requirements.
CAST IRON : We manufacture piston rings from
graded cast iron which provide good sealing over a wide temperature
range in applications where adequate lubrication can be provided.
All of our cast iron rings are heat tensioned.
BRONZE : Our Bronze Piston Rings offer great
wear resistance and are preferred for high temperature and pressures
where lubrication may be marginal. The most commonly used Bronze
Grade is 80:10:10 (CU-SN-PB) Chilled Casting. Various other grades
are also available for different service conditions.
CARBON FILLED TEFLON : Piston rings manufactured
from Carbon filled Teflon offers good compressive and shear strength,
hardness and wear resistance. They are particularly effective
in non-lubricated services and have got excellent corrosion resistance.
