Key Features
Excellent thermal stability
Lower pressure drop or greater hydraulic capacity
Exceptional mechanical strength
Resist all alkalis, solvents, and acids (except hydrofluoric acid)
Maintains its excellent chemical resistance at temperatures well beyond the limits of standard ceramic (it should not be used in systems where the bars will be exposed to superheated steam for an extended period of time)
Applications
Sulphuric Acid Towers
Grid Blocks Range
Acid Resistant Grid Blocks are ideal for use as secondary support in sulfuric acid absorbers, driers, coolers, and other highly corrosive applications in large-diameter towers. The superior qualities of Acid Resistant Grid block formulation permit the use of thinner bars and greater center-to-center spacing.Acid Resistant Grid should be used for secondary support with bars placed on 8 in. centers. Acid Resistant Grid bars with Acid Resistant grid blocks also have 15% more free space than a conventional 6-in. center installation using cross partition rings. The square stacking pattern of Acid Resistant Grid Blocks layered above Acid Resistant grid bars provides 72% open area. Acid Resistant grid blocks will retain 50mm saddles.
Technical Specifications
The acid-resistant grid blocks contain a minimum of 23% Al₂O₃ (Aluminum Oxide) and ZrO₂ (Zirconium Oxide), with at least 60% SiO₂ (Silicon Dioxide).
They offer excellent acid resistance, rated at 98% or higher.
Water absorption is minimal, capped at 0.4% or less.
The blocks have a bending strength of at least 650 Kg/cm², ensuring flexibility under stress.
Their compressive strength exceeds 2400 Kg/cm², making them highly durable.
Size tolerances are strict, with length variations of ±1.0 mm, width (thickness) tolerances of ±1.0 mm, and height tolerances of ±2.0 mm, ensuring precision in construction.
