THE STORY

We believe a pipe shouldn't have to choose between strength and protection.

CRA clad steel is our answer: carbon steel carries the load, corrosion-resistant alloy faces the medium for protection — each metal at its best, metallurgically bonded as one. Our proprietary RSP™ technology achieves 0.2–16 MPa bonding force, well above the 0.3 MPa API 5LD minimum. The result is a pipe you can cut, weld, and bend — the liner stays put.

Why CRA Clad?

Two metals. One pipe.

01

The Strength of Carbon Steel

Our outer layer delivers the structural integrity and pressure resistance you expect from high-grade carbon steel — at a cost that makes sense for large-scale infrastructure.

02

The Resistance of Stainless Alloy

The inner liner is where the magic happens. 304, 316L, 2205, or even titanium — whatever your medium demands. The pipe doesn't just carry fluid. It protects itself from it.

03

A Bond That Doesn't Quit

Our proprietary bonding achieves forces of 0.2–16 MPa — well above the 0.3 MPa standard. Cut it. Weld it. Bend it. The liner stays put. Corrosion ends here.

"The future will be made with pipes that don't force engineers to choose between strength and longevity. We built that pipe."

Where We Serve

From the wellhead to the tap — and everywhere in between

Marine

Marine & Offshore

Seawater, subsea pressure, tidal fatigue. When the environment is the enemy, the pipe needs to be the armor.

Chemical

Chemical & Petrochemical

Chlorides, sulfates, acids. The kind of media that destroys carbon steel in months. Our pipes don't blink.

Water

Water & Infrastructure

Municipal supply, fire protection, desalination — clean water deserves a clean pipe. For the life of the building.

Mining and slurry

Mining & Slurry

Iron ore slurry, coal transport, tailings — abrasive media under high pressure. Pipes built for the world's toughest dig sites.

Trusted & Certified

Internationally recognized standards. Independently audited quality.

API-5LD ISO 9001 ISO 14001 OHSAS 18001 HSE CNAS Lab
