Umbhobho wensimbi engenasiciyimathiriyeli eguquguqukayo kwaye ehlala ixesha elide esetyenziswa kuluhlu olubanzi lwamashishini ukusuka kulwakhiwo kunye neemoto ukuya kwimveliso yokutya nesiselo. Ukuxhathisa kwayo kwi-corrosion kunye namandla aphezulu kuyenza ibe yinto efanelekileyo kwizicelo ezahlukeneyo. Xa ugoba umbhobho wensimbi engenasici, ukukhetha uhlobo olululo kubalulekile ekuqinisekiseni iziphumo ezigqwesileyo. Kweli nqaku, siza kujonga eyona mibhobho yentsimbi egqwesileyo yokugoba kunye nento ekufuneka uyiqwalasele xa ukhetha.
Enye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe xa ukhetha umbhobho wensimbi engenasici ukugoba ibakala lezinto. Amabakala ahlukeneyo ensimbi engenasici anemigangatho eyahlukeneyo yokuguquguquka kunye nokuchasana nokuguqulwa ngexesha lokugoba. Amanqanaba ensimbi engenasici ye-Austenitic, afana ne-304 kunye ne-316, aqhele ukusetyenziselwa ukugoba ngenxa yokubunjwa kwawo okugqwesileyo kunye ne-ductility. La mabanga ayakwazi ukumelana nomhlwa kwaye anokwakheka ngokulula abe ziimilo ezintsonkothileyo ngaphandle kokubeka esichengeni isidima sawo sesakhiwo.
Ukongeza kwibakala lensimbi engenasici, ubukhulu bodonga lombhobho budlala indima ebalulekileyo kwiipropati zayo zokugoba. Iityhubhu ezinodonga olubhityileyo ngokubanzi zibhetyebhetye kwaye kulula ukugoba, zizenze zilungele izicelo ezifuna ukugoba kweradiyasi encinci okanye iimilo ezintsonkothileyo. Nangona kunjalo, umbhobho onodonga olungqingqwa unika amandla amakhulu kunye nokuqina, oko kuyenza ibe lukhetho olungcono kwizicelo apho imfezeko yolwakhiwo ibalulekile. Xa ukhetha umbhobho wensimbi engenasici yokugoba, kubalulekile ukuqwalasela iimfuno ezithile zesicelo kwaye ukhethe ubuninzi bodonga oluhlangabezana nezo mfuno.
Enye ingqalelo ebalulekileyo xa ukhethaumbhobho wentsimbi yokugobakukugqiba. Ukugqitywa komphezulu ogudileyo, okufanayo kubalulekile ukufezekisa ukugoba okuphezulu kunye nokuphepha umngcipheko wokuqhekeka komphezulu okanye iziphene. Ukugqitywa okugudisiweyo okanye okubrashiweyo kudla ngokukhethwa kwizicelo zokugoba kuba zibonelela ngomphezulu ohambelanayo onciphisa umngcipheko wokungaphumeleli kwezinto ngexesha lenkqubo yokugoba.
Xa kuziwa kwiintlobo ezithile zombhobho wensimbi engenasici, umbhobho ongenamthungo udla ngokuba lukhetho lokuqala lokugoba. Umbhobho ongenamthungo wenziwa ngaphandle kwe-welds, okubangelwa isakhiwo esifanayo kunye neepropati ezihambelanayo zoomatshini kulo lonke ubude bombhobho. Oku kwenza umbhobho ongenamthungo ulungele ukugoba kuba unamandla aphezulu kunye nemfezeko xa kuthelekiswa nombhobho odityanisiweyo.
Ukongeza kwizinto eziphathekayo zemibhobho yensimbi engenasici, inkqubo yokugoba ngokwayo idlala indima ebalulekileyo ekufezekiseni iziphumo ezifunwayo. Iindlela zokugoba ezichanekileyo, ezifana nokusebenzisa izixhobo ezichanekileyo zokugoba kunye nokuqinisekisa ulawulo oluchanekileyo lwe-radius ye-bend kunye ne-angle, zibaluleke kakhulu ekunciphiseni umngcipheko wokungaphumeleli kwezinto kunye nokufezekisa ngokuchanekileyo, ukugoba okuphezulu.
Isishwankathelo, ukukhetha owona mbhobho wentsimbi egobileyo ogobileyo kufuna uqwalaselo ngononophelo lwebakala, ubukhulu bodonga, ukugqitywa komphezulu kunye nenkqubo yokuvelisa. Amanqanaba ensimbi engenasici ye-Austenitic, afana ne-304 kunye ne-316, aqhele ukusetyenziselwa ukugoba ngenxa yokubunjwa kwawo okugqwesileyo kunye nokuxhathisa ukubola. Iityhubhu ezinodonga olubhityileyo zivumela ukuguquguquka okukhulu, ngelixa iityhubhu ezinodonga olungqingqwa zinika amandla amakhulu kunye nokuqina. Umbhobho ongenamthungo onomphezulu ogudileyo udla ngokuba lukhetho lokuqala lokugoba izicelo. Ngokuqwalasela le miba kunye nokusebenzisa iindlela ezifanelekileyo zokugoba, ukugoba komgangatho ophezulu wemibhobho yensimbi engenasici kunokufezekiswa kwiinkqubo ezahlukeneyo.
