Product Description

Product Description

HD-STEEL metallurgically bonded bimetallic cladding pipe is a premium solution for pipelines in demanding and corrosive environments. Unlike traditional lined or weld-overlay pipes, our product uses a revolutionary metallurgical bonding process that permanently fuses an inner corrosion-resistant alloy (CRA) layer to an outer carbon steel or low-alloy steel pipe. This advanced manufacturing technique ensures a seamless and inseparable bond, providing superior performance and reliability.

This pipe is ideal for industries facing severe corrosion and erosion challenges, including oil and gas, chemical processing, and petrochemicals. It delivers the high corrosion resistance of expensive CRA materials on the inside, with the structural integrity and cost-effectiveness of standard carbon steel on the outside.

Advantages

Unmatched Integrity and Reliability

The cladding CRA layer and the outer carbon steel are joined at a molecular level, creating a true metallurgical bond. This eliminates the risk of delamination, buckling, or separation that can occur with mechanically lined or weld-overlay pipes, especially under high pressure and temperature fluctuations.

Exceptional Corrosion and Erosion Resistance

The clading layer, made from materials like SS316L, nickel -based alloys, etc., provides outstanding resistance to sweet and sour corrosion (H₂S and CO₂), chloride stress corrosion cracking, and erosion. This protects the pipeline from premature failure and significantly extends its service life.

Simplified Fabrication and 50% cost saving

We use JCO forming and TIG Welding tech, and metallurgical composite plate as raw materal, this simplifies the fabrication process, reducing both project timelines and costs compared to other cladding methods.
