Hunter Steel Flanges offers a complete range of Cladded Fittings, Flanges, and Pipes designed to deliver corrosion resistance, mechanical strength, and cost efficiency in demanding service conditions. Our products are manufactured by applying a corrosion-resistant alloy (CRA) layer over carbon steel or low alloy steel base materials using advanced weld overlay or explosion bonding techniques.

These cladded components are ideal for offshore platforms, refineries, petrochemical units, and other critical process systems where exposure to harsh chemicals, seawater, sour gases, or high-temperature fluids demands superior corrosion protection without compromising structural strength.

Our cladded elbows, tees, spectacle blinds, Paddle blanks, Paddle spacers, and flanges comply with international standards and undergo stringent quality testing to ensure reliable performance in high-pressure and high-temperature environments.

 

Key Features :

• Corrosion resistance at a reduced cost compared to solid alloy
• Strong mechanical integrity of carbon/low alloy steel base
• Wide selection of CRA materials to match fluid conditions
• Available in all standard sizes, classes, and thicknesses
• Custom configurations and cladding thicknesses on request
