Ukuncedisa ekukhetheni izixhobo zombane ezichanekileyo ezingaqhushumbayo, namhlanje siqaqambisa umahluko phakathi kweebhokisi zesiphambuka ezinobungqina bokudubula kunye neebhokisi zemibhobho yobungqina bokudubula.. Nangona zombini zizinto eziphambili kwiinkqubo zombane ezingenakuqhambuka, ziyahluka kakhulu ngomsebenzi kunye neempawu, ngaphandle kwamagama abo afanayo.
Iibhokisi zeNxulumano eziBoniweyo:
Ukuqala ngeebhokisi zesiphambuka ezinobungqina bokudubula, ezi zixhobo zisebenza njengeendawo zoqhagamshelwano phakathi kokuhanjiswa kwamandla, izixhobo zombane, kunye nocingo lwangaphandle. Badlala indima ebalulekileyo kukhuseleko lomgca, imicu yetheminali yezindlu okanye iitheminali zoqhagamshelo ezinesixhobo sokutshintsha. Ngokuqhelekileyo, ezi zixhobo ziyilelwe ukuba zisuswe ukuze kube lula ukugcinwa kunye noqwalaselo.
Iibhokisi zemibhobho yobungqina bokuqhuma:
Ukuqhubela phambili kwiibhokisi zemibhobho yokuthintela uqhushumbo, ezi zisetyenziswa xa ubude bombhobho bungaphezulu kwemida ethile, okanye xa kukho ukutenxa okanye ukugoba okugqithisileyo kwindlela yocingo. Kwiimeko ezinjalo, ukongeza ibhokisi ye-conduit kwiindawo ezicwangcisiweyo kuququzelela ukuthungelwa kocingo kunye nolawulo olulula. Ezi bhokisi zivala umsantsa kwiindlela zokubeka iintambo ezintsonkothileyo.
Zombini iibhokisi zokuhlangana kunye nebhokisi ze-conduit zenziwe ngokusasazwa kwealluminiyam engeyiyo yobhedu enento ekwaziyo ukumelana nomhlwa., indawo egqunywe ngumgubo. Bahlangabezana nemigangatho efunekayo yobungqina bokudubula, ukuqinisekisa ukhuseleko kwiindawo ezinobungozi.
