Izinga lepayipi elingenalutho liyisici esiyinhloko ekunqumeni ikhwalithi yeipayipi elingenamthungo.Ukuze kuqinisekiswe inqubekelaphambili enengqondo yenqubo yokubhoboza futhi kutholwe amapayipi angenamthungo ekhwalithi ephezulu, izidingo eziqinile kufanele zibekwe ku-geometry, isakhiwo samandla aphansi kanye nesimo esiphezulu sepayipi elingenalutho.

Uma ububanzi beshubhu elingenalutho likhulu kakhulu noma i-ellipse inkulu kakhulu, izimo zokuluma ngesikhathi sokubhoboza zizowohloka, futhi ukugoqa okungaphakathi kuzobangelwa ngenxa yokucindezelwa ngokweqile kobubanzi obungenalutho beshubhu.

Inhlangano yangaphakathi isho ukuncipha kanye ne-porosity emaphakathi, ukunqwabelana kwezinto ezingezona ezensimbi, nokuqukethwe kwegesi.Ubunzima balesi sidingo buyahlukahluka ngokusetshenziswa kwamapayipi angenamthungo kanye nohlobo lwensimbi.

Into ebaluleke kakhulu izinga eliphezulu le-tube elingenalutho, ngoba i-tube blank iyiswa ku-tube engenamthungo yomkhiqizo kunoma yiliphi idolobha elikhubazekile, futhi indawo lapho abakhubazekile bevame ukubangelwa ukugxila kokucindezeleka, ukuguqulwa kwepulasitiki kuzokwenza ukukhubazeka kujule nangaphezulu.

Ukufingqa, ukuze kukhiqizwe imikhiqizo yepayipi engenamthungo ephezulu, kuyisinyathelo esibaluleke kakhulu sokuqinisekisa ikhwalithi yepayipi elingenalutho.
