Abstract

PURPOSE:To manufacrure a porous seamless pipe having a prescribed void volume and small dispersion of the void volume by kneading metallic powder having a specified particle size with a binder, a lubricant and water in a specified ratio and by extruding and sintering the kneaded material. CONSTITUTION:To 5kg metallic powder having <=0.85mm. particle size are added 50-300g binder, 50-250cc lubricant and 0.5-1.2l water, and they are kneaded. The kneaded material is extruded and sintered to manufacture a porous seamless pipe. Thus, a long pipe having >=5 ratio of length/diameter can be manufactured.
