Co-Extruded Clad Pipes Our co-extruded clad pipes are developed using advanced bimetallic metallurgical composite seamless pipe technology. Through typical hot extrusion or hot extrusion plus cold forming processes, they achieve metallurgical bonding between cladding and base materials, fundamentally overcoming the limitations of traditional welding processes. Core Features Metallurgical Bonding: Strong metallurgical interface between cladding and base materials through specialized extrusion High Strength: Superior structural integrity and load-bearing capacity Corrosion Resistance: Optimized for highly corrosive environments Bonding Strength: Reliable composite interface strength without welding defects Technical Advantages Compared with traditional welded clad pipes, our co-extrusion technology addresses critical issues: Eliminates low bonding strength defects of welded cladding Avoids weld seam susceptibility to corrosion Ensures uniform cladding thickness and properties throughout the entire pipe length Creates a seamless structure with enhanced integrity and durability Applications Co-extruded clad pipes are engineered for demanding industrial environments, including: Heat exchange piping for lye recovery boilers Oil transportation piping in corrosive downhole environments Heat receiving piping for waste incineration boilers Other severe service conditions requiring both strength and corrosion resistance Value Proposition By combining the mechanical properties of the base material with the excellent corrosion resistance of the cladding material, our high-quality composite pipes significantly extend service life, reduce maintenance costs, enhance operational safety, and deliver exceptional value to customers.
