for the Oil Well Industry

Lower Oil Well Completion 
and Production Costs

1) SINTERED SCREEN DESIGN – Poroplate filter media are made from multiple layers of woven wire cloth sintered together into a rigid porous medium.  The various wire mesh layers are selected to achieve accurate particle size control while maximizing flow rates.  Purolators’ proprietary sintering process metallurgically bonds each stainless steel wire to adjacent wires and layers of screen.  This yield self-supporting filter media, which do not deform even under extreme pressures.

2) RUGGED CONSTRUCTION – The Poroplate medium is combined with a protective shroud into a tubular screen jacket assembly.  The entire assembly is then MIG welded to a high strength perforated base pipe.

3) SUPERIOR DIRT HOLDING CAPACITY – Purolator’s Poroplate design yields a substantial increase in dirt holding capacity compared to competitive screens.

4) INCREASED POROSITY – Poroplate media have an inflow surface area range of 30% to 40% compared to wire wrap screens and other sintered powder metal designs.  As a result, Poromax® and Poroplus® screens provide lower Delta P, therefore higher production rates and extended life.

5) OPTIONS:  Poromax® and Poroplus® screens are available in 75, 125, 175, and 250 micron filtration ratings.  Standard alloy is 316L SS with alloy 20 corrosion resistant alloy as an option.  Various shroud options and base pipes are also available.

6) POROPLATE® TUBE ASSEMBLIES - Poroplate® tube assemblies are available direct from Purolator Facet.
