Industrial linings that take the wear so your plant doesn't

Abrasion, impact and corrosion are the fastest way to wear out unlined steel plant. Slurry pipes, tanks, chutes and screen decks all erode in service, driving repeat replacement cost and unplanned downtime. AU Industries supplies industrial linings and wear lining solutions that move that wear into a replaceable lining instead of the equipment itself, extending service life across mining, minerals processing and heavy industry in South Africa.

We line in-house and on site, matching the lining to the wear mechanism: resilient rubber for slurry abrasion, harder and premium compounds for impact and cutting duty, chemical-resistant compounds for acid and hydrocarbon service, and ceramic-embedded panels for the most severe transfer-point and chute service. Every surface is prepared to SA 3 standard before lining, the single biggest factor in long-term adhesion.

Types of industrial lining and when each is used

Rubber lining

The general-purpose industrial lining for slurry and process plant. Natural rubber lining in 40 Shore absorbs fine-particle abrasion in pipes, cyclones, pumps and tanks; 60 Shore resists the cutting and gouging of coarse material in chutes and hoppers. Applied as bonded sheet and vulcanised in our autoclave or cured on site.

Premium and high-silica compounds

Where standard rubber is being replaced too often, our in-house AU Premium 38 and 60 Shore Pink compounds extend the interval between relines in the highest-wear zones, at a higher price per square metre but a lower cost per tonne handled.

Ceramic-embedded rubber wear panels

For sliding abrasion and high-impact zones that cut through rubber alone, such as transfer points, chute liners and crusher discharge, alumina ceramic tiles embedded in a rubber matrix combine the hardness of ceramic with the impact absorption of rubber. See our ceramic-embedded wear panel work.

Chemical-resistant linings

Bromobutyl for acid plants, CIL and CIP tanks and water-treatment vessels; nitrile where oils, fuels and hydrocarbons would swell natural rubber; neoprene for weathering and moderate chemical exposure. All milled as rubber sheeting in Boksburg.

Pipe wear lining for slurry systems

Rubber lined pipework, bends, spools and fittings fabricated and lined in our workshop, with thickness stepped up at bends and reducers where the flow changes direction and wear concentrates.

Where industrial linings fail, and how we prevent it

Most lining failures are adhesion failures, not wear failures. A lining that lifts at an edge or blisters under the surface is nearly always the result of poor surface preparation, contaminated bonding or a cure that was not completed. Our process closes each of those gaps: grit blasting to SA 3 standard, bonded application by experienced lining technicians, controlled autoclave or on-site cure, and spark testing of every lined surface before it goes back into service. Where the wear profile is uneven we increase lining thickness locally at impact and turbulence points rather than over-lining the whole component.

Industries we line for

Gold, platinum, coal, copper, uranium and titanium mining and minerals processing, chemical plants, water and wastewater treatment and general heavy industry, from our Boksburg facility across South Africa and on site in Mozambique, Namibia, Zambia, Botswana and Zimbabwe.

Frequently Asked Questions

What industrial linings does AU Industries supply?+

We supply rubber linings (40 and 60 Shore natural rubber, premium 60 Shore pink and A38 pink, bromobutyl, and nitrile), ceramic-embedded rubber wear panels, and rubber lined pipework and fittings. Linings are applied to tanks, pipes, chutes, hoppers, cyclones, screen decks, and pulley lagging, and fabricated or lined in our Boksburg facility.

How do I choose between rubber and ceramic wear lining?+

Rubber lining handles fine to medium slurry abrasion and absorbs impact through resilience — it's the right choice for most pipes, tanks, and cyclones. Ceramic-embedded panels are specified for the most severe sliding-abrasion and high-impact zones such as transfer points, chute liners, and crusher discharge, where the hard ceramic resists gouging that would cut through rubber alone. We assess particle size, velocity, and impact angle before recommending.

What surfaces and equipment can be wear lined?+

Tanks and vessels, slurry pipework and fittings, transfer chutes and hoppers, cyclone feeds, screen decks, pump housings, and pulley lagging. If a steel surface is eroding in service, it can usually be protected with a lining matched to the wear mechanism.

Do you line on-site or in your workshop?+

Both. Smaller and fabricated items are lined in our Boksburg workshop under controlled autoclave cure; large fixed plant is lined on-site with grit blasting to SA 3 standard, bonded application, and spark testing. We provide on-site lining across South Africa, Mozambique, Namibia, Zambia, Botswana, and Zimbabwe.

How long do industrial wear linings last?+

Service life depends on the wear mechanism, particle size, velocity, and chemistry. Properly specified 40 Shore rubber typically delivers 12–36 months in slurry service; premium and ceramic-backed linings extend that further in severe-wear zones. Surface preparation to SA 3 standard before lining is the single biggest factor in avoiding premature adhesion failure.

What is the difference between industrial linings and wear linings?+

Industrial lining is the broad term for any protective layer bonded to plant and equipment, whether it protects against abrasion, impact, chemical attack or corrosion. Wear lining is the subset specified for mechanical wear: sliding abrasion and impact. AU Industries supplies both, from chemical-resistant bromobutyl and nitrile linings for acid and hydrocarbon service to rubber and ceramic-embedded wear linings for slurry and transfer-point duty.

Which industrial lining is best for slurry pipework?+

For most slurry lines, 40 Shore natural rubber at 6mm to 12mm, with thickness stepped up at bends and reducers where the flow changes direction. Coarse, sharp or high-velocity slurry moves the specification to 60 Shore or a premium high-silica compound, and ceramic-embedded panels are reserved for the worst impact points. We fabricate and line pipework in our Boksburg workshop.

Can you re-line equipment that has an old lining on it?+

Yes. We strip the failed lining, inspect the steel for corrosion or pitting, repair where needed, grit blast to SA 3 standard and apply the new lining. Re-lining is done in our workshop for pipes, spools and fittings, and on site for tanks, launders and fixed plant.
