This GR1 titanium perforated disc is made from commercially pure Grade 1 titanium, a material known for its corrosion resistance and dependable performance in tough service conditions. The standard configuration has an Ø18 mm circular body with 19 through-holes of Ø1.8 mm arranged evenly across the surface, plus pre-drilled mounting holes that simplify installation. We produce these discs by precision stamping or laser cutting, which gives consistent hole geometry, burr-free edges, and tight dimensional repeatability from piece to piece.

The disc is designed to handle controlled media flow, striking a practical compromise between mechanical strength and open area. In process equipment, it serves as a flow distribution plate, ventilation component, gas or liquid guide, and protective baffle-anywhere uniform distribution and reliable support are needed.

Grade 1 titanium stands up to seawater, chlorides, and a broad range of chemicals-exactly the kind of media that quickly eats through ordinary metals. It keeps its strength at moderate temperatures, lasts a long time, and doesn't demand much attention between service intervals.

The hole layout smooths out the flow, cuts down pressure irregularities, and keeps gas or liquid moving evenly across the whole disc face. Mounting holes come pre‑drilled, so you can bolt or pin the disc straight onto your equipment without any on‑site drilling or custom brackets. These discs turn up regularly in chemical reactors, electrolytic cells, scrubbers, and other process installations where corrosion resistance and predictable flow control are part of the daily running requirements.

Product Features

Even Hole Distribution

The disc carries 19 through-holes of Ø1.8 mm arranged in a regular pattern. Gas or liquid passing through is split into multiple fine streams that spread naturally across the equipment cross-section, avoiding concentrated flow toward any single area.

Backpressure Control

The Ø1.8 mm hole size creates moderate local resistance, giving the fluid time to mix thoroughly before passing through the disc. Pressure drop remains steady, and blower or pump load fluctuates little. No major piping modifications are needed.

Simple Mounting

Mounting holes are machined to match the user's equipment interface. On-site installation involves aligning the disc with the flange or bracket holes and securing it with bolts. No additional drilling, tapping, or welding is required.

Corrosion Resistance

GR1 takes seawater, chlorides, and most chemicals. No pitting, no hole growth, no edge deterioration. Runs for years in corrosive service.

Resistance to Fouling

The dense oxide layer on GR1 titanium gives the surface a smooth finish. Crystallized deposits, polymers, or by-products in the media do not readily adhere to hole walls. After months of continuous operation, measured hole diameter shows little reduction, and the open area remains close to the original value.

Temperature Range

GR1 works from -269°C up to 300°C. Push it past 300°C and the surface oxidizes. Don't run it with concentrated sulfuric, hydrochloric, or hydrofluoric acid-they'll attack the metal. Before you order, double‑check your actual fluid and temperature.

Application Scenarios

Chemical reactor liquid distributors – In batch or continuous stirred reactors, the disc mounts at the inlet to split the feed stream into multiple fine jets, promoting even distribution across the catalyst bed or reaction zone. Grade 1 titanium withstands organic acids, chlorinated hydrocarbons, and temperatures up to 300°C, keeping hole geometry and flow splitting consistent over long runs.

Electrochemical cell separators and flow guides – For chlor-alkali or hydrometallurgical cells, the disc fits between electrodes as a flow guide, directing electrolyte across electrode surfaces to reduce concentration polarisation. The perforations allow chlorine or hydrogen to escape freely, while titanium resists high chloride levels and current densities without leaching metal ions.

Gas distribution plates in scrubbers and absorption towers – Mounted at the bottom or below packing, the disc breaks rising gas streams into 19 small jets, improving gas-liquid contact across the column.

Laboratory micro-reactor components – Used as catalyst supports or flow-switching baffles in fixed-bed reactors and membrane electrode test units, the disc delivers precise gas distribution at low flow rates (mL/min range). Quick-swap of different hole sizes adjusts pressure drop, and the mounting holes allow direct connection to standard tube fittings without rework.

Anti-erosion plates and water distributors in thermal desalination/evaporators – Positioned at steam inlets or condensate returns, the disc buffers high-velocity steam impact on tube bundles and evenly spreads condensate over heat exchange surfaces. GR1 titanium offers superior resistance to pitting in hot brine, outperforming 304/316L stainless and extending maintenance intervals.

Protective baffles for ventilation and filtration in food/pharmaceutical applications – Upstream of sterile filters, the disc prevents particle clogging and evenly disperses incoming air to avoid surface turbulence. Titanium is non-toxic, non-leaching, and compatible with food contact and biocompatibility, with a finish that cleans easily with steam or chemical sanitisers.

Frequently Asked Questions

What's the open area ratio?

The standard disc has 19 holes of 1.8 mm on an 18 mm body. The hole layout provides enough open area for steady flow and even pressure distribution. If your flow or pressure drop requirements differ, we can adjust hole diameter, count, or arrangement.

How are these discs made?

We pick stamping, laser cutting, or machining based on thickness, how many you need, and the tolerances called out on the drawing. Thin material and high volumes-stamping. Thicker plate or small batches-laser or CNC. Whichever route we take, the hole positions come out on spec, edges are clean, and the disc fits when you go to install it.

What do you need for a custom order?

Send us the outer diameter, thickness, hole size, hole layout, and mounting hole positions. Also include the fluid, temperature, pressure, flow rate, and quantity. That lets us match the disc to your setup.

Can this disc handle seawater or chemicals?

Yes. GR1 takes seawater, chlorides, and most chemicals. You see them in chemical plants, marine gear, and desalination-anywhere corrosion is the main concern.

How does a perforated disc differ from a porous titanium filter?

Different jobs. Perforated discs have machined holes for flow direction, distribution, venting, or support. Porous filters are sintered with open pores to trap particles and separate phases. Use the disc when you need distribution; use the filter when you need filtration.
