Izici ze-pipe ye-polyethylene composite eqinisiwe ngensimbi zingafingqwa kanje: 1. Ukuhlanganiswa kwesakhiwo: kwenziwe ngensimbi yesikhumba kanye ne-polyethylene plastic composite; 2. Izinzuzo zokusebenza: isikhumba sensimbi sinikeza amandla aphezulu nokungaguquguquki, kanti i-polyethylene plastic inikeza ukumelana nokugqwala nokugqokwa; 3. Izici eziphelele: inezinga eliphezulu lokuqinisa izindandatho nokumelana nokulimala, kanti iphinde ibe lula ukuze ithuthwe kalula futhi yakhiwe; 4. Izici zokusetshenziswa: inqubo yokuhlanganisa ilula futhi ifanele izidingo ezahlukene zezimboni.
