摘要
双金属管是一种功能材料 ,作为管道输送材料具有许多优点。根据输送物料的性质 ,采用塑性变形复合方法在管道内壁镶衬异种或同种金属管 ,可以实现以下目的 :①增强管道内表面的耐腐蚀性和耐磨性 ;②降低摩擦系数 ,减小物料的输送阻力 ;③便于管道的加工、安装和维修。因此 ,用双金属管制作的管道可以用于各种条件下的气力输送和浆体输送。
As a kind of functioning material, the dual metal pipe has a number of advantages when used for pipe line purpose. Depending on different natures of materials to be conveyed, the pipe inner surface can be lined with a metal either the same as or other than the pipe base metal by means of the plastic deformation complex technique so as to meet the following requirements:1) increasing both corrosion resistance and wear resistance of the pipe inner surface; 2) reducing the friction factor and the resistance against the materials being conveyed in the pipe line; 3) easy processing, installation and maintenance of the pipe line. As a result, pipe lines made with dual metal pipes are applicable for transport of gas and slurry materials under different conditions.
