I-Spiral Welded Tube Ukushisela i-Arc Yamapayipi Egesi Yemvelo

Ishubhu Elihlanganisiwe Eliyindilinga Lokushisela I-Arc Yamapayipi Egesi Yemvelo Isithombe Esifakiwe

Incazelo emfushane:

Ukushisela i-arc kuyisinyathelo esibalulekile enqubweni yokukhiqizaishubhu elihlanganisiwe eliyindilingaikakhulukaziipayipi legesi yemvelos. Kuhilela ukusebenzisa amazinga okushisa aphezulu ukwakha isibopho esiqinile nesihlala isikhathi eside phakathi kwamapayipi, ukuqinisekisa ukusebenza okuthembekile nokuhlala isikhathi eside. Kulesi sihloko, si'Ngizogxila ezinkingeni zepayipi legesi yemvelo elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe elihlanganisiwe nokuthi kungani linjalo'ingxenye ebalulekile embonini yamapayipi.

Ngobaipayipi legesi yemvelos, ukuphepha nokuthembeka kubaluleke kakhulu. Ukushisela i-arc kudlala indima ebalulekile ekuqinisekiseni ukuthi la mapayipi ayakwazi ukumelana nezimo ezinzima abhekene nazo ngesikhathi sokuphila kwawo. Inqubo yokushisela i-arc ihilela ukusebenzisa ugesi ukukhiqiza ukushisa okukhulu okuncibilikisa imiphetho yamapayipi bese kuwahlanganisa ndawonye.

Esinye sezici ezibalulekile okufanele uzicabangele lapho ushisela i-arc amapayipi egesi yemvelo uhlobo lwendlela yokushisela esetshenziswayo.ishubhu elihlanganisiwe eliyindilingas, indlela evame ukusetshenziswa kakhulu ubuchwepheshe bokushisela i-arc engaphansi komhlaba (i-SAW). Lokhu kuhilela ukusebenzisa i-granular flux, ethululelwa endaweni yokushisela ukuze kudalwe umoya ovikelayo ovimbela ukushisela kanye nezinye izinto ezingcolisayo ukuthi zingathinti i-weld. Lokhu kuphumela ekushiseleni kwekhwalithi ephezulu, okufanayo okunamaphutha amancane.

Okunye okubalulekile okufanele kucatshangelwe lapho kushintshwa i-arc amapayipi egesi yemvelo ukukhetha izinto zokugcwalisa i-weld. Izinto zokugcwalisa zisetshenziselwa ukugcwalisa noma yiziphi izikhala noma ukungahleleki kushintshwa, okudala isibopho esiqinile nesihlala njalo. Kumapayipi ashintshwayo ajikelezayo, kumele kusetshenziswe izinto zokugcwalisa ezihambisana nezinga elithile lensimbi elisetshenziswayo kanye nezimo zemvelo lapho ipayipi livezwa khona. Lokhu kuqinisekisa ukuthi i-weld ingamelana nezingcindezi namazinga okushisa atholwa amapayipi egesi yemvelo.

Ngaphezu kwezici zobuchwepheshe zokushisela i-arc, kubalulekile futhi ukucabangela iziqu kanye nolwazi lomuntu oshiselayo owenza umsebenzi. Ukushisela i-arc yamapayipi egesi yemvelo kudinga izinga eliphezulu lekhono kanye nobuchwepheshe, kanye nokuqonda okuphelele kwezinselele ezihlukile kanye nezidingo zomsebenzi. Kubalulekile ukusebenza nabashiseli abanolwazi nabaqinisekisiwe abangakhiqiza njalo amashiseli asezingeni eliphezulu ahlangabezana nezindinganiso eziqinile zomkhakha.

Ekuphetheni, ipayipi legesi yemvelo elihlanganisiwe eliyi-spiral welded arc liyingxenye ebalulekile embonini yamapayipi. Lidinga ukucatshangelwa ngokucophelela amasu okushisela, izinto zokugcwalisa, kanye neziqu zomshiseli owenza umsebenzi. Ngokuqinisekisa ukuthi lezi zici zithola ukunakwa okufanele, kuzokwazi ukudala amapayipi egesi yemvelo ahlangabezana nezidingo zomkhakha zokuphepha, ukuthembeka kanye nokusebenza kwesikhathi eside.
