Our Overlay Welding Clad Steel Pipes represent the pinnacle of corrosion-resistant engineering, designed specifically for the most demanding industrial environments. By utilizing advanced hot wire TIG welding technology, we fuse high-performance alloys—such as stainless steel or hard-facing alloys—onto a robust carbon steel base, delivering the mechanical strength of steel with the superior chemical resistance of specialized cladding.
Engineered to meet rigorous international standards including API 5LD, these pipes and fittings are ideal for transporting aggressive fluids or gases containing solid particles. Whether facing extreme abrasion or corrosive chemical exposure, our overlay welding solutions significantly extend the service life of your infrastructure, reduce maintenance downtime, and optimize overall operational efficiency.

Overlay welding involves depositing a layer of corrosion-resistant alloy via TIG welding onto the surface of the base metal, whereas standard cladding often involves mechanical bonding or rolling. Our method ensures a metallurgical bond for superior adhesion.
Our products are primarily manufactured in accordance with API 5LD, ensuring the highest industry standards for lined and clad steel pipes used in oil, gas, and chemical sectors.
Yes, we can apply various high-hardness and wear-resistant materials, including specific stainless steel grades or hard alloys, depending on the abrasive or corrosive nature of the fluid being transported.
Our overlay welding capabilities for pipe fittings extend up to a maximum diameter of DN2100, allowing for large-scale industrial application.
Automation eliminates human error, providing a continuous and stable weld bead. Features like breakpoint memory and automatic crater filling ensure seamless transitions and structural integrity.
Absolutely. By using hard-alloy overlay layers, the internal surface becomes highly resistant to abrasion, making it ideal for transporting gases or fluids containing solid particles.
