Component Specifications

Definition
A basket frame is a rigid structural component designed to securely hold catalyst pellets or other media within chemical processing equipment. It provides mechanical support, maintains proper bed geometry, ensures uniform flow distribution, and withstands thermal and pressure stresses during catalytic reactions. The frame typically consists of welded or assembled metal sections with precise openings to contain media while allowing fluid passage.
Working Principle
The basket frame operates by creating a contained volume for catalyst media within process vessels. It maintains structural integrity under operational conditions (temperature, pressure, flow rates) while allowing reactants to flow through the catalyst bed with minimal pressure drop. The frame's design ensures proper catalyst distribution, prevents channeling, and supports the weight of both the catalyst and any accumulated deposits during operation.
Materials
Stainless steel (304, 316, 321), nickel alloys (Inconel, Hastelloy), titanium, or specialized corrosion-resistant alloys depending on process conditions. Material selection based on temperature range (-50°C to 1000°C), pressure (up to 300 bar), and chemical compatibility with process media.

Frequently Asked Questions

What factors determine basket frame material selection?

Material selection depends on process temperature, pressure, chemical compatibility (especially with catalysts and reactants), corrosion resistance requirements, thermal expansion characteristics, and mechanical strength needs for the specific application.

How does basket frame design affect catalyst performance?

Proper frame design ensures uniform flow distribution, prevents catalyst settling or channeling, maintains bed geometry, minimizes pressure drop, and provides adequate structural support to prevent catalyst damage during operation or regeneration cycles.

What maintenance considerations exist for basket frames?

Regular inspection for corrosion, deformation, or blockage; cleaning to remove deposits; verification of structural integrity; and replacement when wear exceeds design tolerances or when process conditions change significantly.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
