Ukuze kuhlangatshezwane nezidingo zokuphakelwa kwamanzi okuthuthwa kwendle emadolobheni, kuvinjwe ukugqwala nezinye izinto eziyingozi ukungcoliswa kwamanzi kampompi futhi kuvinjwe ukugqwala kwamapayipi, ipayipi lensimbi elidonsa amanzi elisetshenziselwa ipayipi lokuphakela amanzi emadolobheni, udonga lwangaphakathi lolwelwesi lukasimende luvamise ukumbozwa.
Kunezinhlobo ezimbili zezindlela zokumboza zokwenza ulwelwesi lukasimende lodaka lwepayipi lensimbi le-ductile: ukufutha kanye nolwelwesi olumaphakathi. Ulwelwesi lukasimende olunamekwe ngale ndlela lunobuso obushelelezi, obulinganayo, obuyisicaba, amandla okubopha okuphezulu anodonga lwamapayipi, akulula ukuwa, kanye neziqu zemishini yokukhiqiza ephezulu.
Umshini wethu wokwakha usimende uyisimo-sobuchwepheshe-wobuciko obusetshenziselwa ukugcwalisa amapayipi ngodaka lukasimende kuyilapho uwazungezisa futhi kusetshenziswa{3}}isipina esinesivinini esikhulu. Le nqubo isetshenziselwa ukuthuthukisa ukuqina kwamapayipi nokwandisa isikhathi sabo sokuphila.
Amashadi ashisayo: umshini wokugcwalisa usimende, iChina, abahlinzeki, abakhiqizi, imboni, owenziwe eChina
