Abstract

The invention relates to a plastics pipeline comprising at least one pipeline end ( 1 ) and at least one support ring ( 2 ). It was the underlying object of the invention to improve a plastics pipeline of the type described at the outset in such a way that the support sleeve or the support ring ( 2 ) remains firmly connected to the pipeline even in the event of the plastics pipeline being stored in the presence of high air humidity and temperature. This object is achieved by virtue of the fact that the blow molded pipe section ( 1 ) runs through the support ring ( 2 ) and, as viewed radially, is pressed from the inside outward against the support ring ( 2 ), wherein the pipe section ( 1 ) engages around the support ring ( 2 ), such that the support ring ( 2 ), with its outer surface, and the pipe section ( 1 ), with its outer surface, are substantially in alignment.

Claims (23)

1. A plastics pipeline comprising at least one pipeline end and at least one support ring, wherein each of the at least one pipeline end comprises a blow molded pipe section which runs through the at least one support ring, wherein the blow molded pipe section engages around the at least one support ring, such that the at least one support ring, with its outer surface, and the blow molded pipe section, with its outer surface, are in alignment;

an elastomer hose is disposed upon the at least one pipeline end and the at least one support ring;

the elastomer hose is clamped upon the at least one pipeline end with a clamping ring; and

the at least one pipeline end comprises opposing chamfers which extend partially around the at least one support ring, and wherein the elastomer hose is clamped upon the at least one pipeline end and over at least one chamfer.

2. The plastics pipeline as claimed in claim 1 , wherein the at least one support ring comprises chamfers, which, as viewed radially, are arranged on the outside and, as viewed axially, are arranged on both sides on the at least one support ring.

3. The plastics pipeline as claimed in claim 1 , wherein the plastics pipeline is leaktight.

4. The plastics pipeline as claimed in claim 1 , wherein the at least one support ring is disposed around a parison for forming the at least one pipeline end.

5. The plastics pipeline as claimed in claim 4 , wherein the at least one support ring has a defined position upon the at least one pipeline end.

6. The plastics pipeline as claimed in claim 1 , wherein the at least one pipeline end comprises an annular recess, and wherein the at least one support ring is situated in the annular recess in an immovable positive engagement in an axial direction.

7. The plastics pipeline as claimed in claim 1 , wherein the elastomer hose is compressed upon the at least one pipeline end and the at least one support ring, and wherein the elastomer hose is undamaged.

8. The plastics pipeline as claimed in claim 1 , wherein the at least one pipeline end comprises opposing undercuts which extend partially around the at least one support ring, and wherein the elastomer hose is clamped upon the at least one pipeline end and over at least one undercut.

9. The plastics pipeline as claimed in claim 8 , wherein the elastomer hose is clamped upon the at least one pipeline end in a leaktight manner.

10. The plastics pipeline as claimed in claim 1 , wherein the elastomer hose is clamped upon the at least one pipeline end in a leaktight manner.

11. The plastics pipeline as claimed in claim 1 , wherein the at least one pipeline end comprises opposing undercuts which extend partially around the at least one support ring.

12. A plastics pipeline comprising:

at least one pipeline end and at least one support ring,

each of the at least one pipeline end comprises a blow molded pipe section which runs through the at least one support ring,

the blow molded pipe section engages around the at least one support ring, such that the at least one support ring, with its outer surface, and the blow molded pipe section, with its outer surface, are in alignment;

an elastomer hose is disposed upon the at least one pipeline end and the at least one support ring; and

the at least one pipeline end comprises opposing chamfers which extend partially around the at least one support ring, and wherein the elastomer hose is clamped upon the at least one pipeline end and over at least one chamfer.

13. The plastics pipeline as claimed in claim 12 , wherein the at least one support ring comprises chamfers, which, as viewed radially, are arranged on the outside and, as viewed axially, are arranged on both sides on the at least one support ring.

14. The plastics pipeline as claimed in claim 12 , wherein the plastics pipeline is leaktight.

15. The plastics pipeline as claimed in claim 12 , wherein the at least one support ring is disposed around a parison for forming the at least one pipeline end.
