Imibhobho yentsimbi edityanisiweyo ye-Spiral yonke yamkela inkqubo ye-arc ye-arc entywilayo, imibhobho yentsimbi edityanisiweyo ethe tye iye yantywiliselwa i-arc edityanisiweyo imibhobho yentsimbi yomthungo omfutshane we-UOE, kunye nomthungo othe tye we-high-frequency resistance welding for short ERW.
Xa kuthelekiswa ne-arc welding ephantsi kwamanzi, i-high-frequency resistant welded steel pipe (ERW steel pipe) ayifaki nayiphi na into yokudibanisa ngexesha lokudibanisa.Ke ngoko, i-weld eyenziweyo ihambelana ngokupheleleyo nokwakheka kweekhemikhali zesiseko setsimbi.Emva kokuba umbhobho wensimbi udityaniswe, uhlanjululwe ukwenza uxinzelelo lwangaphakathi lomsebenzi obandayo, kwaye uxinzelelo lwangaphakathi lwe-welding luphuculwe, ngoko ke iimpawu zomatshini ezibanzi zombhobho wensimbi we-ERW zingcono.Kodwa okwangoku, abavelisi abamelwe yiShanghai Ellison kunye neGuangdong Panyu Zhujiang Steel Pipe Factory bavelisa kuphela imibhobho engaphantsi kwe-φ355mm, kwaye imibhobho yegesi enobubanzi obukhulu ayinakunyulwa.Longitudinal submerged arc welding (UOE umbhobho yentsimbi) isebenzisa post-weld ebandayo ulwandiso inkqubo yokwandisa umbhobho, ngoko ubungakanani bejometri umbhobho wentsimbi UOE ichanekile ngokwentelekiso, kunye nomgangatho iqabane xa umbhobho yentsimbi UOE idityanisiwe ilungile. ukuqinisekisa umgangatho we-welding.Inxalenye yoxinzelelo lwangaphakathi iyapheliswa.Ukongeza, i-welding ye-multi-wire (i-three-wire, i-four-wire) isetyenziselwa i-UOE yentsimbi ye-welding welding.Le nkqubo ye-welding ivelisa amandla omgca omncinci ngexesha le-welding kwaye inempembelelo encinci kwindawo echaphazelekayo kubushushu besiseko sesinyithi.I-post-pass welding wire ye-multi-wire welding inokudlala indima ekupheliseni uxinzelelo oluveliswa ngexesha lokudibanisa kwi-welding wire yangaphambili, ngaloo ndlela iphucula iipropati zomatshini wombhobho wensimbi.
Xa kuthelekiswa spiral welded umbhobho, ubude umthungo weld yomthungo ngqo phantsi arc welded umbhobho wentsimbi mfutshane, ngoko ke iziphene welding kunye neempembelelo zincinci.Kumbhobho woxinzelelo oluphezulu, isiseko sesinyithi sombhobho othe tye sinokufikelela kwi-100% yokufumanisa impazamo ye-ultrasonic yeeplate zetsimbi nganye nganye, ukuhlangabezana neemfuno zombhobho woxinzelelo oluphezulu kwisiseko sesinyithi.Nangona kunjalo, nangona ukusebenza okubanzi kwepayipi yensimbi ye-UOE ingcono kunezinye iipayipi zetsimbi, ixabiso layo eliphezulu lenza abasebenzisi abaswele imali badangele.I-welds yombhobho wentsimbi ejikelezayo isasazwa kwimilo ejikelezayo.Ngokuqhelekileyo, indawo ye-weld yombhobho wensimbi, kubandakanywa ummandla ochaphazelekayo wokushisa we-weld, inxalenye eneempawu ezimbi zomatshini wombhobho wensimbi, ngelixa uxinzelelo lwangaphakathi lwangaphakathi lombhobho woxinzelelo lusasazwa kunye nolwalathiso lwe-axial, kwaye i-spiral welded pipe iyakuthi Amalungu abuthathaka aphephe isalathiso soxinzelelo olukhulu lwangaphakathi, ngaloo ndlela kuphuculwe ukusebenza kombhobho wentsimbi.Ukongeza, ngenxa yokwenziwa komthungo we-welding we-spiral steel pipe kunye nokuphakama kwe-welding seam, kunzima kakhulu ukwenza i-anti-corrosion yangaphandle, kwaye i-gap inokwakheka phakathi kwe-welding seams ezimbini.Iteknoloji inokusombulula i-anti-corrosion yombhobho wensimbi ojikelezayo.
