Thermal Diffusion Tech

Innovative Steel Protection for Extreme Environments

Thermal Diffusion (TD) is a cutting-edge metallurgical process that transforms steel’s surface by creating a corrosion-resistant intermetallic layer, also known as a Thermal Growth Alloy.

Alteriver applies this technology to API-grade steel tubing, delivering cost-effective, durable pipes capable of withstanding the harshest conditions.

How Does Thermal Diffusion Work?

By harnessing the power of Zinc in our ziPLY product line, Alteriver forms a Zn/Fe Thermal Growth Alloy layer on all exposed surfaces of the tubing—inside, outside, and even the threads. This process enhances:

CORROSION RESISTANCE

Protects against harsh chemical environments.

WEAR RESISTANCE

The TDZ layer is 25-35% harder than the underlying steel.

HYDROGEN EMBRITTLEMENT RESISTANCE

Mitigates damage from hydrogen exposure.

Unlike other surface treatments, Alteriver’s TD process doesn’t alter the steel’s mechanical properties or dimensions, ensuring full compliance with API specifications and seamless integration with standard field operations.

Key Advantages of Thermal Diffusion Technology

No structural interference

Maintains the steel’s original properties and dimensions.

Field-ready

Compatible with standard handling and operations.

Durability

Extends the lifespan of production tubing under extreme conditions.

What Thermal Diffusion is NOT

NOT A SURFACE SPRAY

Thermal Diffusion isn’t a coating or surface spray. Unlike chemical sprays, hot-dip galvanizing, and electrochemical galvanizing.

NOT A ZINC LAYER

TD doesn’t apply a “zinc layer” to the surface—it creates a fully integrated, hardened alloy that becomes part of the steel itself.
