ERWkuyinto high-frequency ukumelana Welding iqonde umthungo ashiselwe ipayipi;I-LSAWis ngaphansi kwamanzi arc Welding iqonde umthungo ashiselwe ipayipi;Zombili zingamapayipi ashiselwe ngomthungo oqondile, kepha inqubo yokushisela ihlukile.Ngakho awukwazi ukusho enye yazo egameni lepayipi elishiselwe ngomthungo oqondile.Ipayipi lensimbi elivamile I-SSAW– Kuvunguza ashiselwe ipayipi.I-High frequency straight seam (ERW) ngokuya ngenqubo yokushisela ihlukaniswe nge-induction welding ehlukene kanye ne-resistance welding amafomu amabili, ngokususelwa kumthamo oshisayo ogoqelwe obanzi njengempahla eluhlaza, ngokwakhiwa okuqhubekayo, ukugoba, ukushisela, ukwelashwa kokushisa, ukulinganisa, ukuqondisa, ukusika inqubo.Uma kuqhathaniswa ne-SSAW, ukunemba okuphezulu kwe-dimensional, ukujiya kodonga olufanayo, ikhwalithi ephezulu yendawo, ukucindezela okuphezulu kuyinzuzo yonke.Kodwa okubi ukuthi umkhiqizo kuphela encane ububanzi mncane odongeni ipayipi, weld ukumelana isizukulwane lula, Fusion okungaphelele, umsele ukugqwala amaphutha.Kusetshenziswa kabanzi njengegesi yedolobha, ezokuthutha zikawoyela ongahluziwe.

Impahla yepayipi lensimbi ye-LSAW iyipuleti lensimbi elilodwa eliwugqinsi, insimbi ekubunjweni noma emshinini wokubumba i-medium-voltage (ivolumu), isebenzisa ukushisela i-arc engaphansi kwezinhlangothi ezimbili Uhlu lwalo lokucaciswa komkhiqizo ophelile lubanzi, ukuqina kwe-weld, ipulasitiki, ukufana okuhle nokubumbana, nobubanzi bepayipi elikhulu, ukushuba kodonga, ukumelana okuqinile nokucindezela okuphezulu, izinga lokushisa eliphansi ukumelana nokugqwala, njll. Ekwakhiweni kwamandla aphezulu, ukuqina okuphezulu, ikhwalithi ephezulu yamapayipi kawoyela negesi amabanga amade, ishubhu lensimbi udonga olukhulu kakhulu oluwugqinsi oluqondile umthungo ongaphansi kwamanzi.Ngokwezinhlinzeko zendinganiso ye-API kumapayipi amakhulu kawoyela negesi, lapho indawo ephakeme, ulwandle nedolobha elinabantu abaningi ekilasini 1, 2, i-arc egxilile yomthungo oqondile iyona kuphela ekhethelwe uhlobo lweshubhu.

Ngokwezindlela zokwakha ezahlukene zingahlukaniswa zibe: UOE/JCOE/HME.Imiqulu ye-spiral submerged arc (SSAW) isendleleni ephakathi nendawo yepayipi eyenza i-Angle (eguquguqukayo), eyakha futhi i-welding, i-welding seam ibe yi-spiral, inzuzo iwukuthi ingaveza imininingwane ehlukahlukene yobubanzi bepayipi lensimbi ukucaciswa okufanayo, uhla lwezinto ezingavuthiwe likhulu, i-weld ingagwema ukucindezeleka okuyinhloko, isimo sokucindezeleka sihle, okubi ukuthi usayizi wejometri ompofu, ubude be-weld uma kuqhathaniswa nobude bomthungo oqondile, ukukhiqiza kalula imifantu, i-porosity, i-slag, i-weld defects. njenge-welding, i-welding stress yisimo sokucindezeleka esiqinile.Imithetho neziqondiso ezijwayelekile zesikulufu sokuklama ipayipi likawoyela negesi ibanga elide I-Spiral submerged arc ingasetshenziswa kuphela kumakilasi amathathu, indawo yekilasi.I-4 angaphandle le nqubo izothuthukiswa izinto zokusetshenziswa esikhundleni sensimbi plate, ukwakha kanye Welding, ke Welding futhi mafutha, ebandayo ukwandisa, ngemva Welding, izinga Welding iseduze UOE tube, ekhaya akukho inqubo enjalo, isiqondiso imboni yethu ukuze ithuthuke."Igesi yaseNtshonalanga-mpumalanga" isasetshenziswa ukukhiqizwa kobuciko bendabuko, kuphela ukukhuliswa kwembobo yamapayipi.I-United States, i-Japan kanye neJalimane, sekukonke, i-SSAW engeyinhle, ayicabangi ukuthi kufanelekile ukusebenzisa isiqu se-SSAW;I-Canada ne-Italy ingxenye isebenzisa i-SSAW, isiRashiya, inani elincane lokusetshenziswa kwe-SSAW, futhi yenze isimo esiqinile esihambisanayo, ngenxa yezizathu zomlando, i-trunk eminingi yasekhaya nayo iwukusebenzisa i-SSAW.
