Rebuildable slurry conduit elbow
First Claim
1. A rebuildable conduit elbow assembly comprising:
- an inner replaceable element, hereinafter referred to as a liner, having a wear surface, said liner comprising an integral member forming a monolithic arcuate tube defining conduit means therein, said arcuate tube extending throughout substantially most of a bend being traversed by said conduit elbow assembly, said liner further comprising at least two mating replaceable members, whereby a loose fit and a plurality of said mating replaceable members combine to enable adjustment of at least one of said mating replaceable members, thus allowing said conduit elbow assembly to be adjustably connected to piping, andan outer housing comprising at least two mating sections having juxtaposed faces, each of said mating sections having a flange projecting radially therefrom, and both said flanges being located at said juxtaposed faces such that said flanges are juxtaposed one another and means for maintaining said flanges wherein fluent material is conducted through said liner within said conduit elbow assembly.

Abstract
A conduit elbow assembly has a radially split outer housing and a replaceable liner. The liner fits loosely within the housing so that material flowing in the elbow accumulates in the void formed in the housing. The hardened liner is thus reinforced, rendering both inner and outer liner hardened surfaces usable in resisting abrasive attack prior to liner failure. A removable housing member exposes the liner for cutting during replacement. Holes in the outer housing permit leakage of fluent material upon liner failure, thus indicating the need for repair prior to conduit rupture. The assembly is adaptable to accommodate varying pipe dimensions within a particular nominal pipe size.

4. A rebuildable conduit elbow assembly comprising:
-
an inner replaceable element, hereinafter referred to as a liner, having a wear surface, said liner comprising an integral member forming a monolithic arcuate tube defining conduit means therein, said arcuate tube extending throughout substantially most of a bend being traversed by said conduit elbow assembly, an outer housing comprising at least two mating sections having juxtaposed faces, each of said mating sections having a flange projecting radially therefrom, and both said flanges being located at said juxtaposed faces such that said flanges are juxtaposed one another, wherein fluent material is conducted through said liner within said conduit elbow assembly, a clamp circumferentially surrounding said housing mating section juxtaposed flanges, thereby maintaining said housing mating sections juxtaposed, and at least one circumferential annular spacing means mounted selectively on and to a side of a smaller juxtaposed flange of a smaller one of said housing mating sections, said smaller housing flange and said at least one circumferential annular spacing means thereby being retained juxtaposed by said clamp, whereby housing mating sections of differing flange diameters may be assembled, compatibility thus being provided between said smaller housing mating section and a corresponding relatively larger one of said housing mating sections, whereby said conduit elbow assembly is enabled to include said housing mating sections being of differing dimensions. - View Dependent Claims (5, 6, 7, 8)
