A rolled multi-layer sintered wire mesh cartridge rated 1–200 μm for duties where the element has to be cleaned and returned to service. The sintered stack fixes the aperture, so it does not open under differential pressure, and the rigid wall takes a backwash. Welded in house and batch-tested for bubble point and air permeability.

The multi-layer sintered wire mesh cartridge is a flat sintered sheet rolled into a cylinder and seam welded. A protective mesh, the control layer that sets the rating, a dispersion layer and coarser support layers are sintered into one rigid sheet first, then formed to the housing envelope. Ratings run from 1 to 200 μm, and the element runs in liquid and gas service up to 600 °C.

The purpose of the stack is that the aperture is fixed. A woven opening that is only stacked can shift as pressure rises across a loaded element, but here the layers are diffusion-bonded into one sheet, so the pore the element was measured at is the pore it keeps in service. That is what makes this cartridge the choice where the differential pressure across a loaded element is a design case rather than an incident, and it is also why the rated layer keeps its bubble point after cleaning.

It is also what makes the element cleanable. Because the wall is rigid and the contaminant is held at and near the rated layer rather than through a deep fiber mat, reverse flow lifts it off and the cartridge goes back into service. Lines that backwash on a schedule specify this element for that reason: the running cost is cleaning cycles rather than a stock of replacements.

About 70% of our orders arrive as replacements, against a drawing or an OEM part number; the rest start from operating conditions and our engineers select the layer stack and issue a dimensioned drawing for approval. Forming — rolling, discing, flanging — and welding by TIG, resistance or laser all happen in our plant. Every batch is measured for bubble point and air permeability, and the record travels with the dispatch. Drawing review takes 3–5 working days; samples ship in 20–30 days and production runs take 30–60 days, from a minimum of a few pieces to a few dozen elements.

Key Benefits

What this element buys you in service

  • 01

    Rigid wall, stable aperture

    The layers are sintered into one sheet, so the rated pore size does not creep open as differential pressure rises across a loaded element.

  • 02

    Backwashed instead of replaced

    A rigid sintered wall takes a reverse flow, so the element is cleaned in place or off-line and put back into service.

  • 03

    One aperture along the whole length

    The sheet is sintered before it is rolled, so the rated opening at the seam is the same as anywhere else on the cylinder.

  • 04

    Holds its shape through cleaning

    There is no pleat to distort and no fiber mat to compact: the cartridge keeps its geometry across repeated backwash and handling.

Construction

How the element is built

  1. Protective layer

    A coarse woven mesh on the outside, shielding the rated layer from handling and from the backwash itself.

  2. Control layer — the rated layer

    The woven mesh whose aperture sets the micron rating and the bubble point. The element is measured against this layer, not the stack.

  3. Dispersion layer

    Spreads the flow across the rated layer so it works over its whole area rather than at the point of entry.

  4. Support layers and end caps

    Coarser sintered layers carry the differential pressure; end caps, flanges and adapters are welded in house by TIG, resistance or laser welding.

Materials

Alloys this element is built in

The alloy follows the medium, the temperature and what the element has to resist. Where a duty sits between two of them, an engineer says which one and why.

  • 304 stainless steel

    General industrial duty where corrosion is not the limit.

  • 316L stainless steel

    Chosen where chlorides or acids are present in the process stream.

  • 310S stainless steel

    Heat-resistant grade for continuous high-temperature service.

  • 904L stainless steel

    High-alloy austenitic grade for chlorides and acids.

  • Hastelloy

    Nickel alloy for aggressive media where stainless is not enough.

  • Inconel

    Nickel-chromium alloy for high temperature with corrosion.

  • Monel

    Nickel-copper alloy for chlorides and seawater duty.

  • Titanium

    Corrosive or high-purity service.

  • Nickel alloys

    Aggressive media at temperature, where stainless is no longer enough.

Industries

Where this element runs

The duties this element is bought for, and what it is filtering in each of them.

  • Chemical fiber and polymer

    Polymer melt and spin-line filtration, where a stopped line is the cost that matters.

  • Petrochemical

    Process stream filtration and protection of the equipment downstream.

  • Hydrogen and industrial gas

    Duties where the cartridge is backwashed and returned to service rather than discarded.

  • Semiconductor and high-purity

    Cleanable elements for lines where the batch record has to travel with the part.

Customisation

Built to your drawing

Rolled to your drawing: diameter, length, micron rating, alloy, seam position and the end caps, flanges or adapters that make it fit the housing. Send the drawing, the OEM part number or a used element and we confirm the equivalent — dimensions, medium and connection — before a price is given. Drawing review takes 3–5 working days.

Send what you have — a drawing, a part number, a photograph of the element in place, or just the operating conditions. Nothing is quoted from a part number alone.

Why Us

Tested before it ships, from a plant you can audit

Every element is welded and batch-tested in our own plant, and the batch record travels with the dispatch. About 70% of our work is a replacement for an element already in service, which is why a drawing or a used part is enough to start from.

  • ISO 9001 Quality system
  • 70 / 30 Replacement work to work designed from conditions
  • 30–40% Below the brand element it replaces
  • 3–5 days Drawing review before a quote

Questions

Questions this element raises

Does the micron rating change once the element is loaded?

No. The rating is set by the control layer inside the sintered stack, and because the layers are bonded into one rigid sheet the aperture stays where it was measured. Loading raises the differential pressure; it does not open the pore.

How is a multi-layer mesh cartridge cleaned?

By backwash. The rigid wall takes reverse flow, and the element can also be taken off-line for cleaning. Send the cleaning method and the fluid your line uses and we confirm it suits the element.

Can you match the cartridge we are running now?

Yes — most of our orders are replacements. Send the OEM part number, the drawing or a used element and we confirm the equivalent from dimensions, medium, layer stack and connection detail. Flange and adapter geometry are matched, not approximated.

What is the pressure drop across a clean element?

It depends on the medium, the flow and the rating, so we do not quote a catalogue figure. Send the flow rate, the fluid and the rating you need and we size the layer stack against it.

Which alloy suits our medium?

304 or 316L stainless covers most industrial duty; titanium and nickel alloys are used where chlorides, acids or high purity rule stainless out. Send the medium, its concentration and the operating temperature and we name the alloy.

What ships with the cartridges?

The measured batch record. Bubble point and air permeability are checked on every batch in our own testing lab and the record travels with the dispatch, so you hold the figures the element was accepted against.

Send the drawing, or the duty.

A drawing, an OEM number or a used element is the fastest route to a quote. With only the process — temperature, medium, pressure, flow — our engineers select the medium and issue a drawing for approval before anything is sampled.
