ASME Code Pressure Vessels
Natural Gas Coalescing Filters to 285psig
Rugged Enameled Steel or 304SS Construction
Series
R30 coalescing pipeline filters are fabricated from rugged enameled carbon steel, (R32 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.
Connection
Sizes from 1" to 12"
Male NPT
or raised face flange in-line connections are std. Alternative orientations and sizes are
available. An elevated discharge connection is shown below. A hinged blind face flange
closure assembly with lift lug is standard.
Coalescing
Filter Media
Sparks
#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
contaminates.
Options
Models
R30-0202-MT-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.

the midwestern US. Sparks also provides OSHA Approced platforms to reduce total field
installed costing.
