With the rapid development of modern industry and technology, the performance requirements for pipes are increasing. The traditional single-metal pipe in some specific application scenarios gradually exposed its limitations, such as insufficient corrosion resistance, strength and toughness is difficult to balance and high cost. Metal clad pipe is through the advanced manufacturing process of two or more metal materials composite together to form a new type of pipe with the advantages of different metal materials, it can meet a variety of complex working conditions, while reducing the cost, improve the material utilisation and cost-effective.
Currently common metal clad pipe manufacturing processes include explosive welding, rolled welding, surfacing composite and so on. Usually a metal with good strength and toughness is chosen as the base layer, such as carbon steel or low alloy steel; and a metal with excellent corrosion resistance is chosen as the layer material, such as stainless steel, titanium alloy and so on. Optimisation of performance is achieved through reasonable material matching.
Metal clad pipe combines the high strength of the base material and the corrosion resistance of the layer material, and at the same time has good thermal conductivity, electrical conductivity and processability. Its comprehensive performance is better than single metal pipe, can meet the special needs of different industries. Bimetallic clad pipe is widely used in the oil and gas transmission of acidic oil and gas fields with strong corrosion, water injection well sewage reinjection and marine oil and gas development pipeline project, and various purification condenser, petroleum refining high-temperature condenser and other industries, and its good abrasion resistance and high-temperature resistance can effectively extend the service life of the pipeline.
