Challenge

Premature wearing of piston and rider rings with typical run life varied from less than 1 year up to 2 years. Rings worn and excessive debris present in the cylinders. Premature wearing of the packing rings and breakage of the ring segments. Ring wear leads to high vent leakage.

Solution Highlights

CPI 192 is a special polymer alloy that was developed for extreme services in both lubricated and non-lubricated applications. With a combination of higher strength and higher hardness, CPI 192 material provides extended run life in refinery applications where traditional filled PTFE based materials can experience shorter and inconsistent run life due to a combination of higher pressures and temperatures and when dirt and liquids are present in the gas stream.

Run lives typically extend beyond 3 years.

Minimal wear debris collected in the cylinders and packing cases prevents damage to other components.
