Pipeline lining & steel corrosion protection

Renew the pipe. Stop the corrosion.

Spray-applied polyurea linings rebuild a protective barrier inside and outside aging steel, ductile and concrete pipe, often without digging up the whole run. Learn how rehabilitation projects are inspected, prepared and lined, then talk to an ArmorThane applicator.

All applications
01

Spray-applied linings

A seamless polyurea or polyurethane lining sprayed inside the host pipe adds abrasion and chemical resistance and seals pinholes.

Steel corrosion control

Blasted, primed and coated exterior steel keeps soil moisture, salts and oxygen off the wall that holds the pressure.

Learn more → 03

Inspection & condition

CCTV, wall-thickness readings and coating surveys decide whether a line can be lined or needs structural renewal.

Choosing a method

Spray lining, cured-in-place pipe and sliplining each fit different diameters, bends, flows and budgets.

Why polyurea

A tough elastomer built for buried and exposed steel

Plural-component polyurea cures in seconds, so pipe can return to service quickly. It stretches with thermal movement, bridges hairline defects and holds up to abrasion from solids in the flow. Results still depend on surface preparation and film thickness, which is why the applicator and the spec matter.

  • Fast cure, short outages
  • Seamless, no lap joints
  • Flexible over movement
  • Abrasion resistant

Field

New lines & field joints
How it works

From inspection to return to service

Step 01

Inspect

Camera survey, wall-loss readings and a review of flow, pressure and access points.

Step 02

Prepare

Clean, dry and abrasive-blast to a measured profile; repair holes and joints first.

Step 03

Line & coat

Heated spray equipment builds the specified thickness in controlled passes.

Step 04

Verify

Thickness checks, holiday testing where specified, and records before the line goes back in service.

Questions

Common questions

What is trenchless rehabilitation?

Renewing pipe from inside with little or no excavation.

How do I choose a method?

Pipe diameter, condition, flow, bends, access and structural needs.

Is a spray lining structural?

Some systems are designed as structural, others as protective. Engineers specify which is needed.

Why clean before lining?

Debris, roots and scale prevent bonding and reduce flow.

Can potable water pipes be lined?

Only with products certified for drinking water, such as to NSF/ANSI/CAN 61.

Who can line our structures?

ArmorThane applicators.
