Clif-Clad® Pipe is a superior abrasion resistant piping solution for extreme applications. The clad overlay pipe product was designed to combat severe abrasive wear with moderate to low impact over a wide temperature range. Cladded piping products have all the advantages without the disadvantages of double walls or cast lined pipes.
Clif-Clad® Pipe is a fabricated pipe produced with our industry proven, high quality chrome carbide overlay. It offers outstanding abrasion resistance for most low pressure applications. Clif-Clad® overlay pipe has reduced downtime in various industries including steel, cement, paper, mining, power generation, aggregate, and glass industries. The clad overlay pipe is the preferred choice in the transportation of materials such as: aggregates, ash, coal, gravel, limestone, magnetite, mill scale, mine tailings, ores, pyrites, raw kiln feed, slurries, sludge, slag, and sand.

Fabrication
We recommend the use of Clifton Steel’s fabrication services to eliminate processing and fabrication errors.
Field Fabrication/Modification of Pipe
All pipe products must be supported on both sides of the cut area to prevent damage to the pipe and/or cutting equipment. Normal safety and workmanship practices are recommended.
WARNING: All structural welding must be confined to the base plate and not overlap into the overlay. This procedure will prevent carbon embrittlement and failure of the weld.
Cutting
Joint Preparation
Always inspect surfaces to be welded and avoid welding areas that have tears, cracks and other discontinuities. Clean joint area from at least 1/2″ of weld joint, remove all loose scale, rust, moisture, grease, etc.
Welding
Place welds on exterior of pipe first. Working from the exterior of the pipe, join the pipes using any low carbon electrode. Maintain a maximum of 1/4″ weld fillet per pass, and rotate the pipe during the process to eliminate excessive starting and stopping of the weld. Our Tensaweld Workmate welding wire is compatible for base plate welds, while our Ultra-100, Ultra-200, Ultra-300 are all compatible with the overlay.
