Rubber Lined Mining Pipework

Abrasion-resistant pipe rubber lining for mining

Unlined steel pipework in slurry service erodes fast — bends, reducers, and high-velocity runs wear through first, driving unplanned downtime and repeat replacement cost. AU Industries rubber lines mining pipework to take that wear in a sacrificial, replaceable rubber layer instead of the pipe wall, extending service life across slurry, tailings, and process-water lines.

We fabricate and rubber line pipe spools, bends, reducers, tees, and flanged fittings to your isometrics in our Boksburg facility, then prep, prime, and autoclave-cure the lining in-house. Fabricating and lining under one roof keeps bond quality controlled and the schedule short — and lets us step lining thickness up locally in the bends and reducers where slurry wear accelerates.

What we line for mining pipework

  • Straight pipe spools — carbon steel and HDPE
  • Bends, elbows, and long-radius sweeps
  • Reducers, tees, laterals, and Y-pieces
  • Flanged fittings and pump connection pieces
  • Cyclone feed and underflow pipework
  • Tailings and process-water lines

    • Choosing the lining compound

    • 40 Shore natural rubber — the workhorse for fine-slurry abrasion in pipes and bends.
    • 60 Shore natural rubber — for coarser, impact-loaded slurry where larger particles cut and gouge.
    • Premium 60 Shore pink & A38 pink — high-silica, cut-resistant compounds for sharp-particle duty that chunks standard rubber.
    • Bromobutyl & nitrile — where acid, chemical, or oil exposure is the failure mode rather than abrasion. Custom compounds developed on request.

    Frequently Asked Questions

    What slurry pipework does AU Industries rubber line?+
    We rubber line straight pipe spools, bends, reducers, tees, laterals, and flanged fittings for mining slurry, tailings, and process water service. Pipework is lined in our Boksburg facility and dispatched to mine sites across South Africa, Mozambique, Namibia, Zambia, Botswana, and Zimbabwe.
    Which rubber compound is best for abrasive mining pipework?+
    40 Shore natural rubber is the workhorse for fine-slurry abrasion in pipes and bends, while 60 Shore handles coarser, impact-loaded streams. For high-silica or sharp-particle duty our premium 60 Shore pink and A38 pink compounds resist cutting where standard rubber chunks. The right lining depends on particle size, velocity, pH, and temperature — we specify it against your slurry profile.
    How thick is the rubber lining on mining pipes?+
    Lining thickness is matched to the abrasion profile — typically 6mm for general slurry service, increasing in high-wear zones such as bends and reducers where flow changes direction and wear accelerates. We can step thickness up locally rather than over-lining the whole spool.
    Do you fabricate the pipework as well as line it?+
    Yes. We fabricate carbon steel and HDPE pipe spools, bends, and fittings to your isometrics, then prep, prime, and autoclave-cure the rubber lining in-house. Fabricating and lining under one roof keeps the bond quality controlled and the schedule short.
    How long does rubber lined slurry pipework last?+
    Properly specified 40 Shore lining typically delivers 12–36 months in slurry pipes depending on slurry type, particle size, velocity, and chemistry. Harder and premium compounds extend life further in heavy-abrasion bends and reducers. Surface preparation to SA 3 standard before lining is the single biggest factor in avoiding premature adhesion failure.
