WATERJET MIXING TUBE COMPRISING MULTIPLE COMPONENTS

摘要

A method is disclosed of manufacturing a mixing tube for an abrasive waterjet system. The method comprises providing a plurality of mixing tube components having opposed ends, and each comprising at least a layer of superhard material; and assembling the plurality of mixing tube components. The components are assembled with the layers of superhard material therein extending adjacent to one another about an axis to define a mixing tube with an axially extending bore. Preferably the assembled components define joins between them which extend longitudinally, parallel to the bore. In one version of the method, a groove is formed at the surface of the layer of superhard material of each mixing tube component, the groove extending between the opposed ends of the mixing tube component, and the plurality of mixing tube components are assembled with the grooves therein extending adjacent to one another about an axis to define the axially extending bore. Each mixing tube component may be an elongate body comprising a first layer of substrate material with a second layer of superhard material being located on one side of the body. Alternative versions of the method are disclosed.
