ASME Code Pressure Vessels
Natural Gas Coalescing Filters to 740psig
Rugged Enameled Steel or 304SS
R40 coalescing pipeline filters are fabricated from rugged enameled carbon steel, (R42 are
304SS), designed, constructed, and stamped in accordance with ASME Boiler and Pressure
Vessel Code requirements for unfired pressure vessels. Any model can be modified to more
exactly fit your needs.
#907 media is composed of microfine borosilicate glass fibers bonded with phenolic resin.
Together with a textile prefilter and a final drain layer, these pleated elements are
remarkably effective at coalescing fine entrained oil and aqueous vapor mist from air/gas
flows with very low ?P. Experience has demonstrated high removal (over 90%) in dealing
with 1.0 to 0.3µ aerosols. Other optional filter media such as #926 exceeds 95% removals.
Individual performance will vary with the specific viscosity and vapor pressure of liquid
R40-0202-RF-020 and larger include CS leg supports. (add 18" to OH) Carbon steel
support legs in any length, gauges, special finishes, and head lift assemblies are
optional on any model. Call for information on vessels having other pressure services,
304SS, or other materials of construction.
that saved a plant from shut down. Two ASME code certified coalescing filter-separators
solved a very serious problem. They now protect an existing Downstream unit filled with
costly molecular sieve (over $200,000) from liquid contamination in the gas stream.
Together with a second Sparks filter-coalescer, this unit employs an automatic drain
system and removes over 500 gallons of liquid per day with over 99% efficiency.
