Our Overlay Welding Clad Steel Pipes are engineered to provide an exceptional barrier against extreme corrosion and wear. By integrating high-performance overlay layers—such as stainless steel or hard alloys—onto a robust steel base, we deliver a synergistic solution that combines the mechanical strength of carbon steel with the superior chemical resistance of specialized alloys, specifically designed for the most demanding industrial environments.
Utilizing advanced Hot Wire TIG welding technology and adhering to strict international standards like API 5LD, our cladding process ensures a seamless, stable, and high-density surface. This specialized manufacturing approach is ideal for transporting abrasive fluids or hazardous gases, significantly reducing friction and maintenance costs while maximizing the operational lifespan of your pipeline infrastructure.

Overlay welding provides a precise, high-density protective layer that is chemically bonded to the base steel, offering superior wear resistance and corrosion protection without the weight or cost of a full alloy pipe.
Our products are primarily manufactured in accordance with API 5LD, ensuring they meet the rigorous quality and safety requirements of the global oil, gas, and chemical industries.
Yes, we provide overlay welding for both steel pipes (up to DN1050) and pipe fittings (up to DN2100), ensuring a consistent protective barrier throughout your entire piping system.
Depending on the application, we use various high-hardness and wear-resistant materials, including different grades of stainless steel and specialized hard alloys.
Our system uses automatic spiral welding with breakpoint memory and precise CNC control, which eliminates human error and ensures a continuous, stable weld bead.
Absolutely. The high-hardness overlay layers are specifically designed to resist abrasion from solid particles, making them ideal for slurry or particulate-heavy transport.
