Hastelloy Steel Sintered Sand Filter Screen 1-100 Micron For Pharmaceuticals Industry

A tubular sand filter screen is made in one piece entirely of powdered metal slivers which are molded and sintered to form a metal lurgically integral rigid tubular structure. Aggregate metal particles, for example, stainless steel slivers, are bonded together by interatomic diffusion as a result of sintering the compacted slivers under high temperature and pressure conditions. The sintered metal sand screen performs the function of the conventional prepack assembly as well as the screen function. In one aspect of the invention, the sintered metal screen is subjected to electropolishing to yield an effective porosity of 40-60 mesh, with an average pore size of 150 microns. Most of the surface irregularities are removed by electropolishing, and very few nucleation sites remain where particles in the size range of 74 microns-100 microns can become captured or otherwise lodged to cause plugging of the screen.

Rugged Construction of Sand Filter Screen
The sand filter screen 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 of Sand Filter Screen
JUMAO sand filter screen design yields a substantial increase in dirt holding capacity compared to competitive screens.

Increased Porosity of Sand Filter Screen

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

Options of sand filter screen
JUMAO 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.
