Polyurea pipeline rehabilitation

Give aging pipelines a second life.

Spray-applied polyurea seals corroded, leaking and worn pipe inside and out, and the line is back in service in hours, not weeks. We help contractors start spraying it and help pipeline owners find crews who can.

Why polyurea

The rehab coating that sets before the job gets old.

Polyurea is sprayed hot through a plural-component gun and cures almost on contact. That speed, plus real flexibility, is why it has become a go-to system for pipe that can't be out of service for long.

Fast return to service

Fast-set systems gel in seconds, so crews build full thickness in one visit and lines go back online quickly.

A real corrosion barrier

Seals steel, ductile iron and concrete from the water, soil, chemicals and oxygen that eat pipe.

Moves with the pipe

High elongation lets the coating ride through thermal cycling and ground movement without cracking.

Inside, outside or both

External coatings, internal linings, field joints, culverts and fittings from one material family.

Built for abrasion, impact and rough backfill

Tough enough for grit, slurry and rocky soil, where thin-film coatings wear through. See where crews are putting it to work.

Polyurea vs. the usual

Why crews switch from slow-cure coatings.

Spray polyurea Conventional epoxy & tape
Cure Gels in seconds; handle and inspect quickly Hours to days between coats and before service
Build Full thickness in one multi-pass visit Multiple thin coats or overlapping wraps
Flexibility High elongation that rides through movement Rigid films can crack; tapes can disbond at overlaps
Seams Monolithic, no seams or laps Overlaps and edges that can let water in
Weather window Cures across a wide temperature range Slows or stalls in cold and damp conditions

Ask a specialist
What is a polyurea pipeline coating?

Polyurea is a two-component, fast-setting elastomer that is spray-applied with plural-component equipment. It forms a seamless, flexible membrane on steel, ductile iron and concrete pipe, sealing the surface from water, soil, chemicals and abrasion. It can be applied to the outside of a line, as an internal lining, or both.

Can polyurea be sprayed inside a pipe?

Yes. Internal linings are one of the most common pipeline rehab uses. Larger diameters can be sprayed by hand from inside the pipe; smaller lines use spin-cast or robotic spray heads that travel down the bore. Proper surface preparation and moisture control matter more than anything else.

How fast does a coated line go back into service?

Fast-set polyurea gels in seconds and builds full thickness in a single multi-pass application, so lines often return to service the same day or the next, depending on the system, the service and the owner's inspection requirements.

What does it take to start spraying pipeline coatings?

A plural-component proportioner and spray gun, a way to power and heat it (often a trailer or truck-mounted rig), surface-prep equipment, training, and a supply of pipeline-grade material. The ArmorThane team can walk you through rig options, hands-on training and materials sized to the work you want to chase.

Do you provide training and equipment?

Yes. Through the ArmorThane network you can get spray rigs, materials and hands-on applicator training, plus marketing support once you start bidding pipeline work.
