Amajoyinti okunwetshwa kwenjoloba adlala indima ebalulekile ezinhlelweni eziningi zezimboni ezidinga ukuguquguquka nokuhamba kwezinhlelo zamapayipi.Zisetshenziswa kabanzi ukunxephezela ukwanda okushisayo, ukudlidliza nokungahambi kahle, ukuqinisekisa ukusebenza kahle nokuvimbela umonakalo kumasistimu amapayipi.Kodwa-ke, ukukhetha ijoyinti elifanele lokunwetshwa kwerabha kuhlelo lwakho lokusebenza oluthile kubalulekile ukuze kuqinisekiswe ukusebenza kwalo okuphelele nempilo yesevisi.Kulesi sihloko, sidingida izici ezibalulekile okufanele zicatshangelwe lapho ukhetha i-joint yokwandisa irabha.

1. Izinga lokushisa nokucindezela
Okunye okucatshangelwayo okuyinhloko ekukhetheni ijoyinti yokwandisa irabha izinga lokushisa nezimo zokucindezela elizomelana nazo.Amajoyinti okunweba enjoloba aklanyelwe ukumelana nezinhlobonhlobo zamazinga okushisa nezingcindezi.Ngakho-ke, kubalulekile ukwazi amazinga okushisa aphezulu nobuncane kanye nezingcindezi ilunga elizohlangabezana nalo ukuze kuqinisekiswe ukuthi lilinganiselwe ngokufanele.Ukwehluleka ukukhetha isilinganiso esifanele kungaholela ekuhlulekeni ngaphambi kwesikhathi kwelunga kanye nomonakalo ongaba khona kulo lonke uhlelo.

2. Izidingo zesenzo
Amalunga okwandisa irabha athatha ukunyakaza kwe-axial kanye ne-lateral ezinhlelweni zamapayipi.Ngaphambi kokukhetha ijoyinti yokwandisa irabha, kubalulekile ukunquma ukunyakaza okulindelekile kanye nokususwa okuzokwenzeka ohlelweni.Lokhu kufaka phakathi izici ezifana nokujikeleza kwe-angular, ukucindezelwa kwe-axial kanye nokuchezuka kwezinhlangothi.Ngokuhlola ngokunembile izidingo zokunyakaza, ungakhetha amalunga amunca ngokwanele futhi anxephezele ukunyakaza okulindelekile, avimbele ukucindezeleka ohlelweni lwakho lwamapayipi.

3. Ukuhambisana okusesilinganisweni
Izihlanganisi zokunweba zenjoloba zenziwe ngezinto ezihlukahlukene ezinokumelana namakhemikhali okuhlukile.Kubalulekile ukucabangela imidiya egeleza ngokuhlanganyela okunwetshiwe futhi uqinisekise ukuhambisana nezinto zenjoloba.Amakhemikhali athile noma uketshezi lungehlisa isithunzi ezinye izinhlobo zenjoloba, kubangele ukwehluleka ngaphambi kwesikhathi.Ukwazi ukwakheka kwamakhemikhali kwendawo ephakathi nokukhetha into yerabha ekwazi ukumelana nesenzo esibi esingenzeka kubalulekile ekuphileni isikhathi eside nokuthembeka kwejoyinti lokunweba.

4. Ukwakha nokuqinisa
Izinhlelo zokusebenza ezihlukene zidinga ukwakhiwa okuhlangene okuhlanganisiwe kwenjoloba kanye nezinhlobo zokuqinisa.Angaba amadizayini ane-arch eyodwa noma ama-arch amaningi, ngalinye linikeza amazinga ahlukene okumuncwa nokuvumelana nezimo.Ukukhethwa kwezinto zokuqinisa (njengendwangu noma insimbi) kufanele kusekelwe ezidingweni ezithile zohlelo lokusebenza.Amalungu aqiniswe ngendwangu afaneleka ukucindezela okuphansi nokunyakaza okuthambile, kuyilapho amalunga aqiniswe ngensimbi angcono ekucindezelweni okuphezulu nokunyakaza okukhulu.

5. Ikhwalithi nesitifiketi
Uma ukhetha ijoyinti lokunwetshwa kwerabha, kubalulekile ukucabangela isithunzi somkhiqizi, ulwazi kanye namazinga ekhwalithi.Ukukhetha umkhiqizi onedumela elihle kuqinisekisa ukuthi uthola umkhiqizo ohlangabezana nezindinganiso zomkhakha futhi ohlolwe kanzima.Ukuqinisekiswa okuvela ezinhlanganweni ezaziwayo ezifana ne-ISO noma i-ASTM kunikeza isiqinisekiso esengeziwe sekhwalithi nokusebenza kwamajoyinti okunwetshwa kwenjoloba.

Sengiphetha, ukukhetha ilunga elifanele lokunwetshwa kwenjoloba kudinga ukuhlolwa ngokucophelela kwezimfuneko zokushisa nengcindezi, okulindelwe ukunyakaza, ukuhambisana nemidiya, ukwakhiwa, ukuqinisa kanye nesithunzi somenzi.Ngokucabangela lezi zici, ungakhetha ijoyinti lokunweba lerabha elihlangabezana nezidingo zakho ezithile, uqinisekise ukusebenza okuthembekile nokusebenza kahle kohlelo lwakho lwamapayipi.
