Ipayipi lensimbi elinama-welds lisakazwa ngokuzungeza okuhlobene ne-axis yomzimba wepayipi. Isetshenziswa kakhulu njengamapayipi okuthutha, inqwaba yamapayipi, namanye amapayipi esakhiwo. Imininingwane yomkhiqizo: ububanzi obungaphandle 300 ~ 3660mm, ukujiya kodonga 3.2 ~ 25.4mm.
Izici zokukhiqizwa kwamapayipi ashiselwe ku-spiral yilezi:
(1) Amapayipi anobubanzi obuhlukahlukene bangaphandle angakhiqizwa ngemicu yobubanzi obufanayo;
(2) Ipayipi linokuqondisa okuhle nobukhulu obunembe. I-spiral welds yangaphakathi nangaphandle ikhulisa ukuqina komzimba wepayipi, ngakho-ke asikho isidingo sokulinganisa nokuqondisa izinqubo emva kokushisela;
(3) Kulula ukubona imishini, i-automation, kanye nokukhiqizwa okuqhubekayo;
(4) Uma iqhathaniswa nezinye izisetshenziswa zesikali esifanayo, inobukhulu obuncane, indawo encane yokuhlala kanye nokutshalwa kwezimali, futhi iyakha ngokushesha;
(5) Uma kuqhathaniswa namapayipi ashiselwe ngomthungo oqondile anosayizi ofanayo, umthungo wokushisela ngeyunithi yobude bepayipi mude, ngakho ukukhiqiza kuphansi.

Ukugeleza kwenqubo yokukhiqiza ye-spiral welded pipe:
Izinto zokusetshenziswa zamapayipi ashiselwe ku-spiral zihlanganisa imicu namapuleti. Ipuleti lisetshenziswa uma ukujiya kungaphezu kuka-19mm. Uma usebenzisa amapheshana, ukuqinisekisa ukunikezwa kwezinto okuqhubekayo ngesikhathi sokushisela izinqe zamakhoyili angaphambili nangemuva, idivayisi ye-looper ingasetshenziswa, noma i-fly welding trolley ingasetshenziswa ukuze kuxhunywe i-butt welding. Wonke umsebenzi wokulungiselela impahla ukusuka ekukhumuleni kuye ekushiseleni izinqe ungenziwa eduze kwethrekhi ku-fly welding trolley. Kuqedwe ngesikhathi sokuthutha. Lapho umsila wensimbi ye-strip yangaphambili ubanjwa yi-clamp yangemuva yomshini wokushisela izinqe, i-trolley idonselwa phambili ngesivinini esifanayo nesomshini wokwenza kanye nowokushisela ngaphambili. Ngemuva kokuthi ukushisela izinqe sekuqediwe, i-clamp yangemuva iyakhululwa futhi i-trolley ibuyele ngokwayo. endaweni yokuqala. Uma usebenzisa amapuleti, amapuleti ensimbi eyodwa adinga ukushiselwa ngezinqe abe yimichilo engaphandle komugqa wokusebenza, bese ethunyelwa kulayini wenqubo yokusebenza ukuze ashiswe ngezinqe futhi axhunywe nemoto yokushisela endizayo. Ukushisela izinqe kwenziwa kusetshenziswa ukushisela okuzenzakalelayo kwe-arc, okwenziwa endaweni engaphakathi yepayipi. Izindawo ezingangenwanga zakhiwe futhi zifakwe ngaphambili, bese zilungiswa endaweni yangaphandle yepayipi, bese kuthi ama-welds avunguzayo ahlanganiswe ngaphakathi nangaphandle. Ngaphambi kokuthi umugqa ungene emshinini wokwakha, unqenqema lwe-strip kufanele lugobe ngaphambili ku-curvature ethile ngokususelwa kububanzi bepayipi, ukushuba kodonga, kanye ne-angle yokwakha, ukuze ukugoba kokuguquguquka konqenqema kanye nengxenye ephakathi ngemuva kokwakheka kube. okuhambisana nokuvimbela isici “soqalo” sezindawo zokushisela eziphumela ngaphandle. Ngemuva kokugoba ngaphambili, ingena ku-spiral yangaphambili ukuze yakheke (bona ukuvunguza kwe-spiral) kanye ne-pre-welding. Ukuze kuthuthukiswe ukukhiqiza, umugqa wokwakha kanye ne-pre-welding uvame ukusetshenziselwa ukufanisa imigqa eminingi ye-welding yangaphakathi nangaphandle. Lokhu akukwazi nje ukuthuthukisa ikhwalithi yama-welds kodwa futhi kwandise kakhulu ukukhiqizwa. I-pre-welding ngokuvamile isebenzisa i-welding ye-gas arc evikelekile noma i-high-frequency resistance welding enesivinini esisheshayo sokushisela, kanye ne-welding yobude obugcwele. Le welding isebenzisa i-multi-pole automatic submerged arc welding.

Isiqondiso esiyinhloko sokuthuthukiswa kokukhiqizwa kwamapayipi ashiselwe yingoba ingcindezi ethwala amapayipi iyanda usuku nosuku, izimo zokusebenzisa ziya ngokuya ziba nzima, futhi impilo yesevisi yamapayipi kufanele inwetshwe ngangokunokwenzeka, ukuze iziqondiso eziyinhloko zokuthuthukiswa kwe amapayipi ashiselwe ku-spiral yilawa:
(1) Khiqiza amapayipi anezindonga ezinkulu ezinobubanzi obukhulu ukuze kuthuthukiswe ukumelana nomfutho;
(2) Dizayina futhi ukhiqize amapayipi ensimbi esakhiwo amasha, njengamapayipi ashiselwe enezingqimba ezimbili ezithandelayo, ashiselwe abe amapayipi anezingqimba ezimbili anensimbi ewugqinsi uhhafu wogqinsi lwamapayipi. Akukhona nje kuphela ukuthi amandla abo aphakeme kunamapayipi ongqimba olulodwa obugqinsi obufanayo, kodwa ngeke abangele umonakalo oqatha;
(3) Ukuthuthukisa izinhlobo ezintsha zensimbi, ukuthuthukisa izinga lobuchwepheshe lezinqubo zokuncibilikisa, futhi kwamukele kabanzi izinqubo zokushisa okugingqikayo neziginqika ngemva kokuginqika ukuze kuthuthukiswe ngokuqhubekayo amandla, ukuqina, nokusebenza kokushisela komzimba wamapayipi;
(4) Athuthukise ngamandla amapayipi amboziwe. Isibonelo, ukumboza udonga lwangaphakathi lwepayipi nge-anti-corrosion layer akukwazi nje ukwandisa impilo yesevisi, kodwa futhi kuthuthukise ukushelela kodonga lwangaphakathi, ukunciphisa ukumelana nokungqubuzana kwamanzi, ukunciphisa ukuqoqwa kwe-wax nokungcola, ukunciphisa inani lepayipi. izikhathi zokuhlanza, nokunciphisa ukulungiswa.
