Umbhobho odibeneyo ojikelezayolicandelo elibalulekileyo kumashishini ahlukeneyo kuquka ioyile negesi, ulwakhiwo kunye neziseko zamanzi. Le mibhobho yenziwa kusetyenziswa inkqubo ekhethekileyo ebizwa ngokuba yi-spiral welding, equka ukudibanisa imicu yentsimbi ukwenza imo eqhubekayo ye-spiral. Le ndlela yemveliso inika iingenelo ezininzi, kubandakanya amandla aphezulu, ukuqina kunye nokusebenza kakuhle kweendleko. Ukongeza, imibhobho ye-spiral welded ihambelana nemigangatho yamazwe ngamazwe efana ne-EN10219 ukuqinisekisa umgangatho kunye nokusebenza kwayo.
EN10219ngumgangatho waseYurophu ochaza iimeko zobuchwephesha zokuhanjiswa kwezixhobo ezidityanisiweyo ezakhiwe ngokubandayo zentsimbi engeyiyo i-alloy kunye nentsimbi ecolekileyo. Lo mgangatho uchaza iimfuno zenkqubo yokuvelisa, iimpawu zezinto kunye nokunyamezelana kobukhulu beemibhobho zentsimbi ezidityanisiweyo ezijikelezayo ukuqinisekisa ukuba zifanelekile ukusetyenziswa kwezakhiwo.
Ukuveliswa kwemibhobho yentsimbi edityanisiweyo nge-spiral kuqala kukhetha iikhoyili zentsimbi ezikumgangatho ophezulu, emva koko zivuleke zize zifakwe kumatshini we-spiral welding. Umatshini usebenzisa inkqubo ye-welding eqhubekayo ukudibanisa imiphetho yomcu wentsimbi, okwenza umthungo we-spiral kubude bombhobho. Ii-welds emva koko zivavanywa ngendlela engonakalisiyo ukuqinisekisa ukuthembeka kwazo kunye namandla azo. Emva kwe-welding, imibhobho idlula kwiinkqubo ezahlukeneyo zokugqiba, kubandakanya ubungakanani, ukulungelelanisa kunye nokuhlolwa, ukuhlangabezana neemfuno ze-EN10219.
Enye yezona nzuzo ziphambili zombhobho wentsimbi odibeneyo yikhono lawo lokumelana noxinzelelo oluphezulu lwangaphakathi nolwangaphandle, nto leyo eyenza ukuba ifaneleke ukuthutha ulwelo kunye neegesi kumashishini ahlukeneyo. Ukongeza, inkqubo yokudibanisa umgodi inokwenza imibhobho eneedimitha ezahlukeneyo kunye nobukhulu, inika ukuguquguquka koyilo kunye nokwakhiwa. Le mibhobho ikwamelana nokugqwala, nto leyo ephucula ngakumbi ixesha layo elide kunye nokusebenza kwayo kwiindawo ezifuna amandla.
Ukuthobela i-EN10219 kubalulekile ukuqinisekisa umgangatho kunye nokuthembeka kwemibhobho yentsimbi edibeneyo ejikelezayo. Lo mgangatho ubeka iimfuno ezingqongqo kwisakhiwo sezinto, iimpawu zoomatshini kunye nokunyamezelana kobukhulu ukuqinisekisa ukuba imibhobho iyahlangabezana nemigangatho yokusebenza efunekayo kwizicelo zesakhiwo.
Ukongeza, i-EN10219 ikwachaza iinkqubo zovavanyo kunye neziqinisekiso ekufuneka abavelisi bazithobele, kubandakanya uvavanyo olungonakalisiyo lwee-welds, uvavanyo lokusebenza koomatshini kunye nokuhlolwa okubonakalayo. Ngokulandela le migangatho ingqongqo, abavelisi banokubonelela abathengi ngesiqinisekiso somgangatho kunye nokusebenza kombhobho wentsimbi odibeneyo ojikelezayo.
Ngamafutshane, imveliso kunye nemigangatho yeepayipi zentsimbi ezidityanisiweyo ezikwi-spiral ezichazwe kwi-EN10219 zidlala indima ebalulekileyo ekuqinisekiseni ukuthembeka nokusebenza kwezi zinto zibalulekileyo. Ngokusebenzisa inkqubo yokudityaniswa kwe-spiral kunye nokunamathela kwimigangatho engqongqo yokuvelisa, abavelisi banokuvelisa iipayipi ezikumgangatho ophezulu ezihlangabezana neemfuno zamashishini ahlukeneyo. Ngenxa yoko, i-EN10219 iba sisakhelo esixabisekileyo sokuvelisa, ukuvavanya kunye nokuqinisekiswa kweepayipi zentsimbi ezidityanisiweyo ezidityanisiweyo, okufaka isandla ekusetyenzisweni kwazo ngokubanzi kwiziseko ezibalulekileyo kunye neeprojekthi zokwakha kwihlabathi liphela.
