Testing and repair options for critical dry-gas seal: Updates
Do your research when sending compressor seals out for renovations
Upgrading from traditional compressor seals to advanced
dry-gas seals (DGSs) is entirely feasible and has been pursued
for approximately two decades. Over the last five years, DGS
production for new compressors has increased as well as
well-planned implementation of dry-seal retrofit options.
However, primary emphasis on the manufacture of new DGSs has
resulted in service issues related to product engineering. As
with all industries where demand for new products outstrips
capacity to support existing products, both pricing structure
and lead time for component repairs have come under scrutiny.
This author discusses the issues related to the repair and
testing of DGSs.
