Abstract
A pipe connection includes at least one end of a plastic pipe or a metal plastic composite pipe and one connecting element with at least one support body provided with circumferential ribs, onto which the end of the pipe is slid. For the expansion ratio R(exp) of the pipe connection, the following applies: 0.05<R(exp)=[D(max)/D(internal)]−1<0.35 wherein D(max) stands for the maximum external diameter of the circumferential ribs and D(internal) for the internal diameter of the pipe.
Claims27
Pipe connection, comprising at least one end of a plastic pipe or metal plastic composite pipe and one connecting element with at least one polymeric support body provided with circumferential ribs, onto which the end of the pipe is slid, wherein the plastic pipe or metal plastic composite pipe is made of or comprises at least a layer made of polyethylene selected from the group consisting of PE 100, PE-RT, and crosslinked polyethylene, and the following applies to the expansion ratio R(exp) of the pipe connection:
- 0.05<R(exp)=[D(max)/D(internal)]−1<0.35
- wherein D(max) stands for the maximum external diameter of the circumferential ribs and D(internal) for the internal diameter of the pipe.
Pipe connection, comprising at least one end of a plastic pipe or metal plastic composite pipe, a connecting element with at least one support body provided with circumferential ribs, onto which the end of the pipe is slid, and a polymeric sliding sleeve axially slid onto the expanded end of the pipe, wherein the plastic pipe or metal plastic composite pipe is made of or comprises at least a layer made of polyethylene selected from the group consisting of PE 100, PE-RT, and crosslinked polyethylene, and the following applies to the expansion ratio R(exp) of the pipe connection:
- 0.05<R(exp)=[D(max)/D(internal)]−1<0.35
- wherein D(max) stands for the maximum external diameter of the circumferential ribs and D(internal) for the internal diameter of the pipe.
