Poroplate® Sand Control Screens for the Oil Well Industry

Purolator’s Poroplate® sand control screens offer enhancements to existing gravel pack and sand control systems. These patented high pressure screens offer these unique features and benefits backed by the filtration expertise of Purolator.

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.

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.

Superior Dirt-Holding Capacity
Purolator’s Poroplate design yields a substantial increase in dirt holding capacity compared to competitive screens.

Increased Porosity
Poroplate media have an inflow surface area range of 30% to 40% compared to 10%-20% for wire wrap screens. As a result, Poroplate® screens provide lower Delta P, resulting in higher production rates and extended life.

Options
Poroplate® 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.
