Amajoyinti okunweba irabha adlala indima ebalulekile ezinhlotsheni eziningi zezimboni ezidinga ukuguquguquka nokuhamba kwezinhlelo zamapayipi. Asetshenziswa kabanzi ukukhokhela ukwanda kokushisa, ukudlidliza kanye nokungahambi kahle, ukuqinisekisa ukusebenza kahle kanye nokuvimbela umonakalo ezinhlelweni zamapayipi. Kodwa-ke, ukukhetha ijoyinti lokunweba irabha elifanele lokusetshenziswa kwakho okukhethekile kubalulekile ekuqinisekiseni ukusebenza kwalo okuhle kanye nokuphila kwenkonzo. Kulesi sihloko, sixoxa ngezinto ezibalulekile okufanele uzicabangele lapho ukhetha ijoyinti lokunweba irabha.

1. Izinga lokushisa kanye nengcindezi
Enye yezinto ezibalulekile okufanele uzicabangele ekukhetheni ijoyinti yokwandisa irabha yizimo zokushisa kanye nengcindezi ezizomelana nazo. Amajoyinti okukhulisa irabha aklanyelwe ukumelana nobubanzi bamazinga okushisa kanye nengcindezi. Ngakho-ke, kubalulekile ukwazi amazinga okushisa aphezulu kanye namancane kanye nengcindezi ezohlangabezana nayo ijoyinti ukuze kuqinisekiswe ukuthi ilinganiswa ngokufanele. Ukwehluleka ukukhetha isilinganiso esifanele kungabangela ukwehluleka kwangaphambi kwesikhathi kwejoyinti kanye nomonakalo ongaba khona ohlelweni lonke.

2. Izidingo zesenzo
Amajoyinti okunweba irabha avumela ukunyakaza kwe-axial kanye ne-lateral ezinhlelweni zamapayipi. Ngaphambi kokukhetha ijoyinti lokunweba irabha, kubalulekile ukunquma ukunyakaza okulindelekile kanye nokufuduka okuzokwenzeka ohlelweni. Lokhu kufaka phakathi izici ezifana nokujikeleza kwe-angular, ukucindezela kwe-axial kanye nokuphambuka kwe-lateral. Ngokuhlola ngokunembile izidingo zokunyakaza, ungakhetha amajoyinti amunca ngokwanele futhi abuyisele ukunyakaza okulindelekile, ukuvimbela ukucindezeleka ohlelweni lwakho lwamapayipi.

3. Ukuhambisana okulingene
Amajoyinti okunweba irabha enziwe ngezinto ezahlukahlukene ezinokumelana kwamakhemikhali okuhlukahlukene. Kubalulekile ukucabangela imidiya egeleza ejoyintini lokunweba futhi uqinisekise ukuthi iyahambisana nezinto zerabha. Amakhemikhali noma uketshezi oluthile lungonakalisa izinhlobo ezithile zerabha, okubangela ukwehluleka kwangaphambi kwesikhathi. Ukwazi ukwakheka kwamakhemikhali kwale nto kanye nokukhetha izinto zerabha ezingamelana nesenzo sokugqwala okungenzeka kubalulekile ekudeni nasekuthembekeni kwejoyinti lokunweba.

4. Ukwakhiwa nokuqinisa
Izinhlelo zokusebenza ezahlukene zidinga ukwakheka okuhlukene kwamalunga okukhulisa irabha kanye nezinhlobo zokuqinisa. Zingaba yimiklamo ye-arch eyodwa noma ye-arch eminingi, ngayinye inikeza amazinga ahlukene okumunca ukunyakaza kanye nokuguquguquka. Ukukhetha izinto zokuqinisa (njengendwangu noma insimbi) kufanele kusekelwe ezidingweni ezithile zokusetshenziswa. Amalunga aqiniswe ngendwangu afanelekela ukucindezela okuphansi kanye nokunyakaza okuthambile, kuyilapho amalunga aqiniswe ngensimbi angcono kakhulu ekucindezelweni okuphezulu kanye nokunyakaza okukhulu.

5. Ikhwalithi kanye nesitifiketi
Uma ukhetha ijoyinti yokwandisa irabha, kubalulekile ukucabangela idumela lomkhiqizi, ulwazi kanye nezindinganiso zekhwalithi. Ukukhetha umkhiqizi othembekile kuqinisekisa ukuthi uthola umkhiqizo ohlangabezana nezindinganiso zomkhakha futhi oye wahlolwa kanzima. Isitifiketi esivela ezinhlanganweni eziqashelwayo njenge-ISO noma i-ASTM sinikeza isiqinisekiso esengeziwe sekhwalithi kanye nokusebenza kwamajoyinti okukhulisa irabha.

Ekuphetheni, ukukhetha ijoyinti yokukhulisa irabha efanele kudinga ukuhlolwa ngokucophelela kwezimfuneko zokushisa nokucindezela, okulindelwe ukunyakaza, ukuhambisana kwemidiya, ukwakhiwa, ukuqinisa kanye nedumela lomenzi. Ngokucabanga ngalezi zici, ungakhetha ijoyinti yokukhulisa irabha ehlangabezana nezidingo zakho ezithile, ukuqinisekisa ukusebenza okuthembekile nokuphumelelayo kohlelo lwakho lwamapayipi.
