Metal Ripple Wire Mesh Packing | Corrugated Wire Mesh Distillation Packing Supplier

Engineer's Brief: Metal ripple wire mesh packing is a disc-type structured packing made from fine stainless wire gauze, crimped into corrugated sheets and stacked with adjacent layers crossed 90°. Capillary action on the mesh holds a uniform thin liquid film, so mass transfer stays high while gas-path resistance stays low. It is the default choice for vacuum distillation, thermo-sensitive and hard-to-separate mixtures — not for dirty, scaling or heavily fouling service. FXSINO manufactures 125Y–700Y/X discs in SS304/316L/Ti/Hastelloy, cut to tower ID with manway-assembly segments.

• • Wire mesh corrugated packing — fine gauze (wire Ø 0.10–0.20mm), highest efficiency, low liquid hold-up, fragile against fouling.
• • Orifice/plate corrugated packing — stamped sheet with punched windows, more robust, lower cost, slightly higher HETP. See plate-type structured packing.

• • Low pressure drop — gas flows through open mesh channels; ΔP per theoretical plate is far below random packing.
• • Small liquid hold-up — less residence time, less thermal degradation of heat-sensitive products.
• • High plates/meter — CY type reaches 8–10 theoretical plates/m; short bed height for the same separation.
• • Good at low liquid load — efficiency does not collapse when reflux drops; ideal for batch and fine-chemical runs.
• • Weak scale-up effect — lab data transfers to large column more predictably than random packing.

• • Suspended solids / slurry — mesh clogs, cannot be mechanically cleaned easily.
• • Heavy fouling / polymerization on surface — wire diameter is thin, attack area is large.
• • Strong corrosive + high chloride at temperature — verify alloy; thin wire has less corrosion allowance than plate packing.
• • Very large diameter with cheap-budget constraint — orifice plate packing often gives better $/stage.

• • Clean tower first — any debris in mesh = permanent efficiency loss. No welding slag, no packing film left inside.
• • Disc diameter — slightly under ID (project-specific clearance), wall gap sealed with high-temp gasket or expanded PTFE strip.
• • Cross orientation — upper/lower disc corrugation directions at 90°; never stack same-way.
• • Level & align — packing axis must match tower axis; tilt causes wall channeling.
• • Don't compress — hand-set, no hammering. Mesh deforms, channels shrink, efficiency drops.
• • Distributor above — wire mesh needs ≥90 drip points/m²; pair with trough or orifice-pan distributor. Support below must clear gas path: camel-hump grid.

Q: BX vs CY — which do I pick?

A: BX for general vacuum and throughput-sensitive runs; CY when you need maximum stages in a short bed (isomers, high-purity solvents). CY has higher ΔP per plate, so don't over-specify it for high-capacity columns.

Q: Can wire mesh packing be washed or decoked?

A: Light soluble fouling can be solvent-flushed, but polymer/coke on thin wire usually means replacement. Design with inlet filtration and pre-flash to protect the bed.

Q: How many stages can one tower section give?

A: A 1m bed of 500BX ≈ 4–5 theoretical plates; 700CY ≈ 8–10. Real column efficiency also depends on distributor DQ and wall sealing — send reflux ratio and target purity for a proper stage count.
