Bimetallic Tubes
Dual-Metal Strength for Demanding Thermal & Corrosive Environments
Engineering Composite Strength
Tube Tech® Bimetallic Tubes are composite tubes manufactured by combining two different metals into a single structure — an inner tube and an outer tube. The metallurgical bond is achieved through controlled rolling and drawing, ensuring reliable adhesion, consistent performance and long service life.
In demanding applications involving high pressure, aggressive media, or corrosive environments, bimetallic construction allows the use of a corrosion-resistant inner layer with a high-strength outer layer — delivering a cost-effective alternative to full-alloy tubing by reducing the use of expensive materials to only where they are required.
Key Features
- • Two-metal construction combining corrosion resistance and mechanical strength
- • Strong, uniform bond achieved through rolling and drawing
- • Designed for high-pressure and corrosive service conditions
- • Cost-effective alternative to full-alloy tubes
- • Custom combinations available to suit duty conditions
- • Optional helical fins can be formed on the outer tube surface
