PLASTIC PIPELINE
The invention relates to a plastic pipeline ( 1 ), having at least one radial branch. The invention is based on the object of providing a plastic pipeline ( 1 ) having a radial branch ( 4, 5 ) that avoids the problems of the known configurations. This object is achieved by the plastic pipeline ( 1 ) having in the intended region of the branching a bore ( 2 ) and a saddle-shaped plastic element ( 4, 5 ) with a through-bore ( 6 ), the through-bore ( 6 ) of the saddle-shaped plastic element ( 4, 5 ) being in line with the bore ( 2 ) in the plastic pipeline ( 1 ) and the saddle-shaped plastic element ( 4, 5 ) being formed from a plastics material that can be fused with the material of the plastic pipeline ( 1 ), and the saddle-shaped plastic element ( 4, 5 ) being connected to the plastic pipeline ( 1 ) in a pressure- and fluid-tight manner.
1 .- 6 . (canceled)
7 . A plastic pipeline comprising at least one radial branch, wherein at the at the least one radial branch, the plastic pipeline comprises a bore and a saddle-shaped plastic element having a through-bore, wherein the through-bore of the saddle-shaped plastic element is in line with the bore of the plastic pipeline; and,
wherein the saddle-shaped plastic element is formed of a plastics material that is fused with the material of the plastic pipeline, and wherein the saddle-shaped plastic element is connected to the plastic pipeline in a pressure-tight and fluid-tight manner.
8 . The plastic pipeline as claimed in claim 7 , wherein the saddle-shaped plastic element is a plastic injection-molded part.
9 . The plastic pipeline as claimed in claim 7 , wherein the saddle-shaped plastic element is connected to the plastic pipeline without further additional materials by making the materials of the plastic pipeline and of the saddle-shaped plastic element fused by a laser beam.
10 . The plastic pipeline as claimed in claim 7 , wherein the saddle-shaped plastic element is at least partially comprised of a laser-transparent material.
11 . The plastic pipeline as claimed in claim 10 , wherein the laser-transparent saddle-shaped plastic element is welded to the plastic pipeline securely and fluid-tightly by laser welding in a contact zone between the saddle-shaped plastic element and the plastic pipeline.
12 . The plastic pipeline as claimed in claim 7 , wherein a coating of an elastomeric material is arranged on the saddle-shaped plastic element at a surface facing the plastic pipeline.
13 . The plastic pipeline as claimed in claim 12 , wherein the coating of an elastomeric material provides a seal between components of the branch
14 . The plastic pipeline as claimed in claim 7 , wherein a plurality of annular weld seams are arranged around the bore of the plastic pipeline.
