Component Specifications

Definition
A support grid or plate is a critical structural component installed within a fractionating column to provide mechanical support for internal elements such as trays, packing materials, or other internals. It ensures proper load distribution, maintains alignment, and prevents sagging or displacement during operation, thereby supporting efficient vapor-liquid contact and separation processes.
Working Principle
The support grid/plate functions by distributing the weight of internal components (e.g., trays, packing) evenly across the column's cross-section, preventing localized stress concentrations. It maintains structural integrity under operational loads (including thermal expansion and fluid dynamics) and ensures that internals remain properly positioned to optimize separation efficiency.
Materials
Typically made from corrosion-resistant alloys such as stainless steel (e.g., SS304, SS316), carbon steel with protective coatings, or specialized alloys (e.g., Hastelloy, Inconel) for harsh chemical environments. Material selection depends on process conditions like temperature, pressure, and chemical compatibility.
Technical Parameters
  • Diameter Matches column ID (e.g., 1000-5000 mm)
  • Open Area 60-85%
  • Thickness 10-50 mm
  • Load Capacity 500-5000 kg/m²
  • Surface Finish Ra ≤ 3.2 μm
Standards
ISO 9001, DIN 28011, ASME BPVC
