Ipayipi le-LSAW(Longitudinal Submerged Arc-Welding Pipe), ebizwa nangokuthiIpayipi le-SAWL.Ithatha i-steel plate njengento eluhlaza, ilibumbe ngomshini wokubumba, bese yenza i-arc welding engaphansi kwezinhlangothi ezimbili.Ngale nqubo ipayipi lensimbi le-LSAW lizothola i-ductility enhle kakhulu, ukuqina kwe-weld, ukufana, ipulasitiki kanye nokuvala okukhulu.
Ibanga lobubanzi bepayipi le-LSAW likhulu kune-ERW, ngokuvamile lisuka ku-406mm ukuya ku-2020mm.Ukusebenza kahle kokumelana nomfutho ophezulu, kanye nokumelana nokugqwala kwezinga lokushisa eliphansi.
Ipayipi le-SSAW(Spiral Submerged Arc-Welding Pipe), ebizwa nangokuthiIpayipi le-HSAW(I-Helical SAW), ukuma komugqa we-welding njenge-helix.Isebenzisa ubuchwepheshe bokushisela obufanayo be-Submerged Arc-Welding ngepayipi le-LSAW.Ngokuhlukile i-SSAW ipayipi i-spiral eshiselwe lapho i-LSAW ishiselwe khona ngobude.Inqubo yokukhiqiza igoqa umugqa wensimbi, ukwenza isiqondiso sokugoqa sibe ne-engeli enesiqondiso sesikhungo sepayipi, ukwakha kanye nokushisela, ngakho-ke i-welding seam is in a spiral line.
Ububanzi bobubanzi bepayipi le-SSAW busuka ku-219 mm kuya ku-2020 mm. Ingxenye yenzuzo singathola ububanzi obuhlukene bamapayipi e-SSAW anobukhulu obufanayo bomugqa wensimbi, kukhona isicelo esibanzi somugqa wensimbi eluhlaza, kanye ne-welding seam. kufanele ugweme ukucindezeleka okuyinhloko, ukusebenza kahle ukuthwala ukucindezeleka.
