Enye yezinzuzo eziyinhloko zepayipi lensimbi elivunguzayo yikhono layo lokumelana namazinga aphezulu okucindezela kwangaphakathi nangaphandle.Lokhu kuwenza alungele ukuthutha indle namanzi angcolile, njengoba amapayipi engaphansi kwengcindezi nokugeleza njalo.Ukwengeza, ingaphakathi elibushelelezi lala mapayipi liqinisekisa ukudluliswa koketshezi ngendlela efanele, kuncishiswe ubungozi bokuvinjwa kanye nezithiyo ngaphakathi.uhlelo lomugqa wepayipi.
Ngaphezu kwalokho, amapayipi ensimbi ane-spiral ashiselwe anokumelana okuhle kakhulu nokugqwala nezinye izici zemvelo.Lokhu kubaluleke kakhulu ekufakweni kwendle lapho amapayipi echayeka ezintweni ezonakalisayo nasezintweni ezinolaka.Ukuqina kwala mapayipi kuqinisekisa ukuphila isikhathi eside kwesevisi, kunciphisa isidingo sokushintshwa njalo nokugcinwa kahle, okuholela ekongeni kwezindleko zabaqhubi besistimu yendle.
Ngaphezu kokuhlala isikhathi eside nokumelana, ipayipi lensimbi elivunguzayo liguquguquka kakhulu futhi lingenziwa ngokwezifiso ukuze lihlangabezane nezidingo ezithile zephrojekthi.Atholakala ngobukhulu obuhlukahlukene nobukhulu, okuvumela ukuklama nokuvumelana nezimo.Kungakhathaliseki ukuthi iphrojekthi encane yokuvuselela noma ukunwetshwa kwesistimu yendle, lawa mapayipi angenziwa ngendlela oyifisayo ukuze ahlangabezane nezidingo ezihlukile zesicelo.
Ukufakwa kahle kwepayipi elishiselwe okuvunguza nakho kusiza ukuthuthukisa ukusebenza kahle okuphelele kohlelo lwakho lwamapayipi endle.Ngomklamo wabo ongasindi kanye nokuphatha kalula, lawa mapayipi angafakwa ngokushesha futhi ngokuphepha, ukunciphisa isikhathi sokwakha kanye nezindleko zomsebenzi.Lokhu kunenzuzo ikakhulukazi ezindaweni zasemadolobheni lapho izithiyo zesikhala nesikhathi zibalulekile.
Ngaphezu kwalokho, ukushisela okubushelelezi nokufana okufanayo kwamapayipi ashiselwe athandelene kuqinisekisa ukusebenza okungavuzi, kuvimbela ukulahleka kwendle namanzi angcolile abalulekile, futhi kunciphisa ingozi yokungcoliswa kwemvelo.Lokhu kwethembeka kubalulekile ekugcineni ubuqotho besistimu yendle kanye nokuqinisekisa ukuthuthwa kwamanzi okuphephile nokusebenza kahle.
Njengoba intuthuko kwezobuchwepheshe nezinto zokwakha iqhubeka nokusungula izinto ezintsha embonini yezokwakha, ipayipi lensimbi elivunguzayo lihlala liyingxenye ebalulekile ekuthuthukisweni nasekugcinweni kwamapayipi endle.Ukusebenza kwawo okuqinisekisiwe, ukuqina kanye nokuguquguquka kuwenza ukhetho olubaluleke kakhulu konjiniyela nabaklami abanomthwalo wemfanelo wokudala ingqalasizinda esimeme futhi eqinile.
Kafushane, ukusetshenziswa kwamapayipi ensimbi ashiselwe ku-spiral kusiza ekwakheni isistimu yamapayipi endle eqinile futhi ephumelelayo.Amandla azo angavamile, ukuqina kwawo kanye nokumelana nokugqwala, okuhambisana nokuguquguquka kwawo kanye nokufaka kalula kwawo, kuwenza alungele ukuthutha indle namanzi angcolile.Njengoba isidingo sengqalasizinda yamanzi angcolile enokwethenjelwa nesimeme siqhubeka sikhula, ipayipi lensimbi elishiselwe okugobile lizoqhubeka nokudlala indima ebalulekile ekuhlangabezaneni nalezi zidingo ezibalulekile.
