Imvamisa kunzima kakhulu ukuhlanza udaka nokunye kwangaphandle emapayipini endle. Ngenxa yamapayipi amancane futhi amade, kunzima ukudiliza izinto ezijwayelekile. Ngenxa yalokhu, senze uchungechunge lwemibhobho yokuhlanza ipayipi ephezulu.

Umgomo osebenzayo wale mibhobho ukusebenzisa ingcindezi ephezulu ketshezi ukuvumela umbhobho ukuthi uxhumeke ku-hose ukuze uzobhoboza ngokuzenzakalela kupayipi elincane lokukhipha. Indawo eboshwe ngombhobho ifakwa ngokushesha nge-liquid high pressure, ukuze ipayipi likwazi ukusulwa kalula futhi ngokushesha. Isizathu sokuthi iqhubekele phambili ngokuzenzakalela ukuthi kunezimbobo ezimbalwa zokufaka amanzi ezinengcindezi ngakolunye uhlangothi lombhobho. Lapho uketshezi olunengcindezi ephezulu lufuthwa ngemuva kombhobho, lunikeza umbhobho amandla okusabela phambili. Usebenzisa leli phuzu, umbhobho ungabonakala kalula. Inhloso yokuqhubekela phambili ngokuzenzekelayo.
