Industrial Rubber Lining: Protecting Tanks, Chutes and Equipment

Rubber lining Saudi Arabia - Diode Trading EST

Short answer: Rubber lining is a layer of rubber
sheet fixed inside or on equipment to protect it from abrasion, impact
and corrosion. It is used in chutes, hoppers, tanks, pumps, pipes and
mill equipment. The rubber type, hardness and thickness depend on
whether the main problem is wear, chemical attack or both.

What rubber lining does

Industrial equipment is attacked by abrasive slurries, sharp rock,
acids and alkalis. Bare steel wears through or corrodes. A rubber lining
absorbs impact, resists abrasion and isolates the steel from the fluid.
It is also quieter than steel and helps reduce noise, and worn linings
can be replaced without replacing the whole equipment.

Types of rubber used

Natural rubber: excellent abrasion and cut
resistance, widely used for slurry and mining wear. Not for oils or
strong oxidising chemicals.
Styrene butadiene (SBR): economical, good abrasion
resistance.
Neoprene and others: for added weather or oil
resistance.
Butyl and other chemical-resistant rubbers: for
acids, alkalis and chemical tanks.
Polyurethane: an alternative where cutting and
abrasion are severe. See polyurethane guide.

Always match the rubber to the medium. The wrong rubber swells,
softens or cracks.

Wear lining vs chemical
lining

If the main problem is abrasion and impact (mining, quarry, dredging,
ash), choose a soft, resilient rubber lining that absorbs the energy of
particles. If the main problem is chemical corrosion (acid or alkali
tanks, scrubbers), choose a chemically resistant rubber and an
application that gives full coverage and sealed joints. For both, share
the details.

How linings are installed

Surface preparation: the steel is cleaned, usually
by blasting, to a clean, rough finish.
Adhesive: bonding agents are applied.
Application: rubber sheets are applied to the
surface and rolled to remove trapped air.
Joints and edges: joints are overlapped or butted
and sealed; edges are protected.
Curing: some linings are cured, for example in an
autoclave or by chemical cure.
Inspection: linings are checked for bubbles,
adhesion and thickness; chemical linings are spark tested.

Mechanical fixing (bolted or clamped rubber liners) is another
approach for chutes and mill liners, with replaceable panels.

What to specify

equipment type and size, or drawings
medium (slurry, particle size, acid, alkali) and its
concentration
temperature and flow velocity
required thickness and hardness
bonded or bolted-in lining
required testing and documentation

Common mistakes to avoid

choosing natural rubber for oil or strong oxidising exposure
poor surface preparation, which causes the lining to peel
trapped air under the sheet, leaving bubbles that fail
choosing too thin a lining for heavy impact
ignoring edges, which are where linings start to fail

Questions to ask your
supplier

Can you supply lining sheet only, or also application? What rubber
compounds are available? What thickness and hardness do you recommend
for my particle size and velocity? What documents and test evidence come
with the order?

Maintenance and inspection

Inspect linings during shutdowns for worn spots, blisters, lifted
edges and cuts. Measure the remaining thickness at known wear points.
Patch small damage quickly, because a small break lets material under
the lining and spreads the failure. Record the wear rate, since it tells
you when to plan the next re-lining and helps you pick a thicker or
tougher compound next time.

FAQ

What is rubber lining? Rubber sheet bonded or fitted
inside equipment to resist wear and corrosion.

How long does a rubber lining last? It depends on
the duty. Heavy abrasive service wears linings faster.

Can rubber lining be repaired? Often yes, with
patches and repair compounds, depending on damage.

Is rubber better than steel for wear? For fine
abrasive slurry and impact, often yes.
