Abstract
A branched pipe (5) is manufactured by continuous extrusion in such a manner that a manifold (5a) of a branched pipe (5) is manufactured by extruding plastic material into the space defined by moving chill moulds (1, 2) and a mandrel (10) arranged therein with an extruder (4). The manifold (5a) is provided with branch pipes (5b) simultaneously with the extrusion thereof.
Claims5
A branched pipe comprising a manifold (5a) and at least one branch pipe (5b), wherein the manifold (5a) is manufactured by continuous extrusion and the branch pipe (5b) is extruded simultaneously with the manifold and is arranged to the manifold (5a) during the simultaneous extrusion such that the branch pipe is free of weld lines.
