Amapayipi ensimbi ahlanganisiwe ahlukaniswe kanje:
Ipayipi Elihlanganisiwe Lokumelana Nogesi(ERW),Ipayipi Lensimbi Ejikelezayo(SSAW),Ipayipi Elihlanganisiwe Le-Arc Elifakwe Emanzini Eliyindilinga Eliyindilinga（LSAW）
Usayizi:
①Ipayipi Lensimbi le-ERW:
I-OD: 21.3mm ~ 660mm;Isisindo: 1mm ~ 17.5mm; UBUDE: 0.5mtr ~ 22mtr

③Ipayipi Lensimbi le-SSAW:
I-OD: 219.1mm ~ 3500mm; Isisindo: 6mm ~ 25mm (Kufika ku-1''); UBUDE: 6mtr ~ 18mtr, SRL, DRL
Okujwayelekile kanye Nezinga:
I-ASTM A53, Ibanga A/B/C, i-API 5L, i-PSL1, i-PSL2, i-GR.B/X42-X80, i-ASTM A795, i-ASTM A135, i-ASTM A252, i-GR.1/2/3, i-AWWA C200
▇ ▍ Incazelo
Ipayipi lensimbi elihlanganisiwe lenziwa kusetshenziswa amapuleti ensimbi ayisicaba noma imichilo yensimbi, futhi inqubo yalo yokukhiqiza idala imithungo emzimbeni walo. Ngokukhethekile, lapho kukhiqizwa amapayipi ensimbi ahlanganisiwe, ipuleti lensimbi noma umucu uyagoba bese kamuva uhlanganiswa ube yipayipi eliyindilinga, eliyindilinga noma eliyisikwele. Ipayipi le-LSAW, ipayipi le-SSAW kanye nepayipi le-ERW konke kuyipayipi lensimbi elihlanganisiwe futhi kuhlukaniswa ngokusekelwe endleleni yokushisela. Isibonelo, ipayipi le-LSAW lihlanganiswa ngobude, kanti ipayipi le-SSAW lihlanganiswa nge-spiral. Ipayipi le-ERW lihlanganiswa ngokumelana nogesi, okuholela kumthungo ohamba ngokuhambisana nomzimba wepayipi.

Amapayipi ahlanganisiwe anemvamisa ephezulu ngokuvamile aqondile, kodwa amapayipi ensimbi ahlanganisiwe anemvamisa eqondile awaqondile aqondile. Ipayipi lensimbi elihlanganisiwe elinemvamisa eqondile elenziwe ngogesi eliqinile lenziwa umphumela wesikhumba kanye nomphumela wokusondelana komshini wemvamisa ephezulu ngemva kokuba ipuleti lekhoyili eligoqekile elishisayo lenziwe ngumshini wokubumba, futhi unqenqema lwe-tube blank luyashiswa futhi luncibilike, futhi ukushiswa kwengcindezi kwenziwa ngaphansi kwesenzo se-roller yokucindezela ukuze kufezwe umkhiqizo. Ipayipi lensimbi elihlanganisiwe elinemvamisa ephezulu lihlukile enkambisweni evamile yokushiswa kwamapayipi ahlanganisiwe. Ukushiswa kwenziwa ngezinto eziyisisekelo zomzimba we-strip yensimbi, futhi amandla omshini angcono kunalawo epayipi elihlanganisiwe elijwayelekile. Ubuso bubushelelezi, bunembile kakhulu, buphansi, futhi bunokuphakama okuphansi komthungo wokushiswa, okuzuzisa ekumbozweni kwe-3PE anti-corrosion coating.

I-arc efakwe ngaphansi kwe-longitudinal ikhiqizwa ngokusebenzisa ipuleti elilodwa eliphakathi nendawo nelijiyile njengezinto zokusetshenziswa, ukucindezela (ukugoqa) ipuleti lensimbi ku-mold noma emshinini wokwakha ibe yi-tube engenalutho, kusetshenziswa i-arc efakwe ngaphansi kwe-tube enezinhlangothi ezimbili, nokwandisa ububanzi. Inani lokuphakelwa kwepuleti lensimbi lingalungiswa ngokuzenzakalelayo ngokuya ngamamaki ensimbi ahlukene, ubukhulu bodonga, nobubanzi bepuleti. Ngesikhathi esifanayo, umsebenzi wokunciphisa ukuguqulwa ugwema ngempumelelo imiphumela emibi yokuguqulwa kwesikhunta ekwakhekeni futhi uqinisekisa ukuthi ubude obugcwele bepuleti lensimbi buthambile ngesikhathi senqubo yokucindezela. Isinyathelo sokudla sifana ngesikhathi sokwakheka, siqinisekisa ukuthi i-tube ingenalutho iyindilinga kanye nokuthi i-welding edge ithambile. Umkhiqizo oqediwe unezinhlobo eziningi zemininingwane, futhi i-weld inokuqina okuhle, i-plasticity, ukufana, kanye nokuqina. Inezinzuzo zobubanzi obukhulu bepayipi, ukujiya kodonga lwepayipi, ukumelana nokucindezela okuphezulu, ukumelana nokushisa okuphansi, kanye nokumelana nokugqwala okunamandla.
▇ ▍Ipayipi Lensimbi le-SSAW
Ipayipi elihlanganisiwe elijikelezayo (ipayipi le-SSAW, elibizwa nangokuthi ipayipi le-HSAW). Ipayipi lakhiwa ubuchwepheshe bokushisela i-arc engaphansi komhlaba. Amapayipi ahlanganisiwe ajikelezayo akhiwa kusetshenziswa amapuleti amancane noma ama-hot rolled coils, okwehlisa izindleko zawo zokukhiqiza kakhulu. Umugqa wokushisela ufana ne-helix. Inqubo yokushisela ejikelezayo ivumela ukukhiqizwa kwamapayipi amakhulu afanele ukuthutha uwoyela negesi omningi. Amanye amapayipi e-SSAW ayenqunyelwe ngokomlando ekusetshenzisweni kwengcindezi ephansi.
