4. Umthungo oqondile kagesi oshiselwe ipayipi lensimbi(YB242-63) iyipayipi lensimbi elinomthungo we-weld ohambisana nendawo yobude yepayipi lensimbi.Imvamisa ihlukaniswe ngamapayipi ensimbi kagesi ashiselwe kagesi, ipayipi elicijile elinezindonga ezincane, ipayipi likawoyela lokupholisa i-transformer njalonjalo.
5. Kuvunguza umthungo ongaphansi kwamanzi we-arc oshiselwe ipayipi lensimbi lokuthutha uketshezi olucindezelwe(SY5036-83) yenziwe ngekhoyili yensimbi egoqwe ngokushisayo njengeshubhu elingenalutho, elakheke ngokuvunguza ekushiseni okungaguquki, futhi lishiselwa nge-arc welding engaphansi kwezinhlangothi ezimbili.Isetshenziselwa ukuthutha uketshezi olunengcindezi.Ipayipi lensimbi ye-Spiral seam.Ipayipi lensimbi linamandla okuthwala ingcindezi kanye nokusebenza okuhle kwe-welding.Ngemuva kokuhlolwa okuqinile okunhlobonhlobo kwesayensi nokuhlolwa, kuphephile futhi kuthembekile ukusetshenziswa.Ububanzi bepayipi lensimbi bukhulu, ukusebenza kahle kwezokuthutha kuphezulu, futhi ukutshalwa kwezimali ekubekweni kwamapayipi kungagcinwa.Isetshenziselwa ikakhulukazi amapayipi okuthutha uwoyela negesi yemvelo.
6.Ipayipi lensimbi elishiselwe i-Spiral seam high-frequency weld for transportation fluid transportation(SY5038-83) yenziwe ngekhoyili yensimbi egoqwe ngokushisayo njengeshubhu elingenalutho, ngokuvamile elakheka ngokuvunguza ekushiseni okuphezulu, elishiselwe i-high-frequency lap welding, futhi lisetshenziselwa ukuthutha uketshezi olucindezelwe.Kuvunguza umthungo ipayipi insimbi high frequency ashiselwe.Ipayipi lensimbi linomthamo oqinile wokuthwala ingcindezi kanye nepulasitiki enhle, elungele ukushisela nokucubungula.Ngemuva kokuhlolwa nokuhlolwa okunhlobonhlobo okuqinile nokwesayensi, kuphephile futhi kuthembekile ukusetshenziswa.Isetshenziselwa kakhulu ukubeka amapayipi okuthutha uwoyela, igesi yemvelo, njll.
7. Kuvunguza umthungo ongaphansi kwamanzi we-arc oshiselwe ipayipi lensimbi(SY5037-83) yokuthutha okujwayelekile okunomfutho ophansi wenziwa ngekhoyili yensimbi egoqelwe eshisayo njengeshubhu elingenalutho, elivame ukwakhiwa ngokuvunguza ekushiseni okuphezulu, futhi lenziwa ngokushiselwa kwe-arc okufakwe emaceleni okukabili okuzenzakalelayo noma ukushisela ohlangothini olulodwa. .Amapayipi ensimbi ashiselwe i-arc angaphansi kwamanzi okuthutha uketshezi olunengcindezi ephansi njengamanzi, igesi, umoya nesitimu.
8.Kuvunguza umthungo wepayipi wensimbi oshiselwe imvamisa ephezulu(SY5039-83) yokuthutha okujwayelekile koketshezi olunomfutho ophansi kwenziwa ngekhoyili yensimbi egoqelwe eshisayo njengeshubhu elingenalutho, elakheke ngokuvunguza ekushiseni okungaguquki, futhi elishiselwe i-high-frequency lap welding ukuze kuthuthwe uketshezi olunengcindezi ephansi.Ipayipi lensimbi elishiselwe imvamisa ephezulu.
9. Ipayipi lensimbi eline-spiral-welded yezinqwaba(SY5040-83) yenziwe ngamakhoyili ensimbi agoqelwe ashisayo njengezikhala zeshubhu, ezivame ukwakhiwa ngokuvunguza ngokushisa okuphakeme, futhi enziwa ngokushisela okungaphansi kwe-arc okunezinhlangothi ezimbili noma imvamisa ephezulu yokushisela.Asetshenziselwa izakhiwo zokwakha umphakathi, amadokodo, amabhuloho Amapayipi ensimbi ezinqwaba zesisekelo.
