ELEMENT OF A SOCKET-PIPE SYSTEM, AND PROCESS FOR MANUFACTURING IT |
摘要 |
In the invention proposed, elements (12a, 12b) of a socket-pipe system with at least one socket joint (10) are manufactured in a moulding press from plasticized material made of mixed waste plastic, in particular waste plastic from household rubbish. Not only does this give a stronger socket joint (10), but also enables reinforcing and/or anti-roll ribs (20) to be provided on the outside of the elements. |
