Reactor internals (screens & supports)
Support for the catalyst bed.
Screens, supports and shielding for vessels and reactors: catalyst support grids, V-wire internals, mist eliminators and reinforcement mesh, built to licensor spec.
Reactor internals support the catalyst bed and distribute process flow. Screens and supports are designed for the specified weight, temperature and pressure. Averinox engineers and supplies them in alloys including 321, Inconel™ and Hastelloy™, selected for the process conditions.
The range includes support grids and beams, outlet collectors, scale catchers and V-wire screens. Knitted-mesh mist eliminators and coalescers separate entrained droplets to help protect downstream equipment.
The range also covers anchoring mesh for refractory linings exposed to thermal shock, cathodic-protection tapes for buried pipelines, spacer structures and EMI shielding for sensitive electronics. Vessel internals can be segmented to fit through the manway. Material traceability accompanies the supply; supervision and mounting can be agreed on request.

Frequently asked questions
Can you work directly from our licensor's specification?
Yes, that is routine work. We quote against the licensor spec, supply the documentation package alongside the hardware, and keep full material traceability from melt certificate to installed part.
How do internals get into the vessel through a manway?
Designs are segmented and bolted: each segment passes the manway and assembles inside. We deliver lifting and assembly drawings, and can supervise or perform the installation during your shutdown.
Can parts be ready before our turnaround window opens?
That is the aim of the planning. Send the licensor specification or drawing and turnaround date early so we can assess fabrication, documentation and delivery. Readiness for the shutdown is confirmed after technical and capacity review.
What is a scale catcher and when do I need one?
A scale catcher is a screen basket at the reactor inlet or above the catalyst bed. It captures corrosion products and scale before they enter the bed. A rise in differential pressure between turnarounds while the catalyst remains active can be a reason to assess one. The economic benefit depends on the source and extent of fouling.
Can you build a mist eliminator for an existing vessel without drawings?
Yes. Vessel inner diameter, manway size and the duty (gas, velocity, droplet size) are enough to engineer a segmented pad with support grid. Where needed we measure on site during a stop.
