The utility model discloses a novel wear -resisting composite pipe, include the same interior outer diameter's of metal material first outer tube, second outer tube and third outer tube, the left endat the second outer tube is fixed to first outer union coupling, and the right -hand member at the second outer tube is fixed to the outer union coupling of third, and the inner wall cover of second outer tube is equipped with the inside lining rubber tube of wear -resisting usefulness, and the inner wall cover of first outer tube and third outer tube is equipped with ceramic bushing pipe or metalinternal tube, ceramic bushing pipe or metal internal tube and inside lining rubber tube end to end. The utility model discloses combining several kinds of wear -resistant pipeline advantages, havingremoved the flange of line with rubber pipeline, used ceramic bushing pipe, bimetal pipe and line with rubber pipe, the scene of having realized can be welded, and revealing a little of line with rubber pipeline has been avoided to the advantage of adjustable length, has solved the unable field weld of line with rubber pipeline, and the shortcoming of unable on -the -spot adjustment length, has reduced the potential safety hazard, the cost is reduced at the time of having practiced thrift, also increase the chance for using widely of line with rubber pipeline, thoroughly changed line with rubber pipe connection mode.
