摘要
A pipe end (13) of a pipe (12) consisting of polyolefin is deformed cold, that is to say at ambient temperature, with the aid of an expanding mandrel. Once the expanding mandrel has been withdrawn, the expanded pipe end (13) and a respectively desired connecting part, or the pipe end (11) of a further pipe (10), are plugged onto one another. The pipe end (13) consisting of polyolefin experiences only a reversible deformation and, as a result of it deforming back to its original shape, forms a firm, gas-tight connection to the connecting part or to the other pipe end (11).
