Belling machines

A Rieber type belling process specific for PVC-O pipes (i.e. polymer pipes with oriented molecules) has been developed by Sica, an Italian manufacturer of plastic pipe processing equipment. These pipes have wall thicknesses approximately 35-40% lower than those made of PVC-U with the same operating pressure and make it possible to...

The need for innovative “green” technology in the plastic pipe production industry capable of guaranteeing high performance, process flexibility and ease of use while allowing reduced energy consumption, has become increasingly pressing and has had a marked influence on the design of various types of extrusion line machinery, including...
