Clad pipe systems integrate economical substrates with specialty metals to deliver strength, longevity, and corrosion resistance. Suitable for pipelines transporting hazardous substances, they’re favored in oil sands, hydrotreaters, and ethanol plants. Methods like centrifugal casting, laser cladding, and arc spraying produce layered configurations. Performance depends on bonding strength, grain structure, and thermal resistance. Regulatory compliance, material traceability, and dimensional stability affect acceptance. Trends include digital twin implementation, additive manufacturing, and lifecycle monitoring. Regional variations arise due to policy, demand, and investment climate. Value addition through smart coatings, modular packaging, and end-to-end services enhances marketability and project execution efficiency.
