Corma Inc. has unveiled two innovations in its machinery to produce lightweight corrugated plastic pipe.
The first is a pulsating corrugator, capable of producing pipe with a diameter exceeding 10 feet. The unit is compact, owing to mold blocks that require little space to return to their original positions. The unit has a vacuum- forming design. The first production unit will be delivered later this year, according to Toronto-based Corma.
The second is a double-skin pipe coupling that is created in-line during the production of PVC, polypropylene and polyethylene double-wall pipe. According to Corma, its previous in-line couplings eliminated the need for downstream belling machines.
