Our inert balls (ceramic ball, high-alumina ball, filler material) are widely used to hold catalysts beds in the equipment used in oil refineries and petrochemical industries. One particularly well-known application for these products is the desulfurization process that is needed in hydrorefining equipment.
There is a process for insuring that this desulfurization process is effective and stable. In order to guarantee the quality of this process, the specifications from licensors are already determined and they have become global standards. One of these standards is UOP’s standard. Tipton provides quality products that easily meet the specifications for inert balls set out by UOP and because of this, our products continue to be supplied widely domestically and abroad.
  Tipton’s Product Quality Exceeds Global Standards
 Compare Tipton’s product quality to the global standards for inert balls established by UOP.

8  Bulk density (volume density)
UOP Standards  The minimum bulk density is 85 lb/ft³(1,360kg/m³). Material density must be at least 135 lb/ft³(2,160kg/m³).
Tipton Standards  Please refer to the Products Specifications.
9  Size variation
UOP Standards  Before filling, small or large inert balls must be screened for in each size in order to remove them.
Tipton Standards  We only provide standard inert balls that have been screened during the separation process.
10  Handling
UOP Standards  The Inert Ceramic Balls hall not “dust” I.e., produce small fines, spall, or fracture due to abrasion between Inert Ceramic Ball s or with the container when handled or vibrated.
Tipton Standards  Inert balls are sintered, so they do not break down or “stir up dust.”

* Caution: Particulate may be created by handling or friction caused by vibration.
