Ipayipi lensimbi elishiselwe, elaziwa nangokuthi ipayipi elishiselwe, ipayipi lensimbi elenziwe ngepuleti lensimbi noma ngomugqa wensimbi ngemuva kokucwiliswa nokushiselwa.Ipayipi lensimbi elishiselwe linenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izinhlobo eziningi kanye nokucaciswa, kanye nemishini encane, kodwa amandla ayo ajwayelekile aphansi kunamapayipi ensimbi angenamthungo.Kusukela ngawo-1930, ngokuthuthuka okusheshayo kokukhiqizwa kwensimbi esezingeni eliphakeme eqhubekayo kanye nokuthuthuka kobuchwepheshe bokushisela nokuhlola, ikhwalithi yama-welds ibilokhu ithuthukiswa ngokuqhubekayo, izinhlobonhlobo kanye nokucaciswa kwamapayipi ensimbi ashiselwe kuye kwanda, nokuningi futhi. amasimu amaningi athathe indawo yensimbi engeyona insimbi.Ipayipi lensimbi yomthungo.Amapayipi ensimbi ashiselwe ahlukaniswe abe amapayipi ahlanganisiwe aqondile kanye namapayipi ashiselwe okuvunguza ngokwendlela yokushisela.
Inqubo yokukhiqiza ipayipi ehlanganisiwe ye-seam ilula, ukusebenza kahle kokukhiqiza kuphezulu, izindleko ziphansi, futhi ukuthuthukiswa kuyashesha.Amandla wepayipi elishiselwe okuvunguzayo ngokuvamile aphakeme kunalawo wepayipi elishiselwe ngomthungo oqondile, futhi ipayipi elishiselwe elinobubanzi obukhudlwana lingakhiqizwa nge-billet encane, futhi ipayipi elishiselwe elinamadayimitha amapayipi ahlukene nalo lingakhiqizwa nge-billet. yobubanzi obufanayo.Kodwa uma kuqhathaniswa nobude obufanayo bepayipi lomthungo oqondile, ubude be-weld bukhuphuka ngo-30-100%, futhi isivinini sokukhiqiza siphansi.Ngakho-ke, amapayipi amaningi ashiselwe anama-diameter amancane asebenzisa i-seam welding eqondile, futhi iningi lamapayipi ahlanganisiwe anama-diameter amakhulu asebenzisa i-spiral welding.
Amapayipi ensimbi ashiselwe ahlanganisa namapayipi ensimbi ashiselwe okuthutha uketshezi olunengcindezi ephansi, amapayipi ensimbi ashiselwe okuthutha uketshezi olunengcindezi ephansi, imikhono yensimbi yensimbi ejwayelekile, umthungo oqondile wamapayipi ensimbi kagesi, umthungo ovunguzayo ongaphansi kwamanzi we-arc oshiselwe amapayipi okuthutha uketshezi olucindezelwe, kanye ukuthuthwa kwamanzi okucindezela.Ipayipi lensimbi elivunguzayo elishiselwe imvamisa ephezulu, umthungo ovunguzayo ongaphansi kwamanzi we-arc oshiselwe ipayipi lokuthutha uketshezi olunengcindezi ephansi, umthungo ovunguzayo ophezulu oshiselwe ipayipi lensimbi lokuhamba koketshezi olunengcindezi ephansi, ipayipi lensimbi elivunguzayo lenqwaba.
