▇ ▍ Incazelo
Ipayipi lensimbi elishiselwe lidalwe kusetshenziswa amapuleti ensimbi ayisicaba noma amapheshana ensimbi, futhi inqubo yawo yokukhiqiza idala ama-seams emzimbeni wayo. Ngokukhethekile, lapho kukhiqizwa amapayipi ensimbi ashiselwe, ipuleti lensimbi noma umucu uyagotshwa bese ushiselwa ube yindilinga, umumo wepayipi elivamile noma ukwakheka kwesikwele.Ipayipi LSAW, ipayipi le-SSAW kanye nepayipi le-ERW wonke amapayipi ensimbi ashiselwe futhi ahlukaniswa ngokusekelwe endleleni yokushisela. Isibonelo, ipayipi le-LSAW lishiselwe ngobude, futhi ipayipi le-SSAW li-spiral-welded. Ipayipi le-ERW lishiselwe ukumelana nogesi, okuholela kumthungo ohamba ngokuhambisana nomzimba wepayipi.
▇ ▍Ipayipi lensimbi le-ERW
Amapayipi ashiselwe imvamisa ephezulu ngokuvamile ane-slit eqondile, kodwa amapayipi ensimbi ashiselwe ahlukene awawona ngempela ashiselwe imvamisa ephezulu. I-high-frequency straight-slit kagesi ukumelana ne-welded steel pipe yenziwa umphumela wesikhumba kanye nomphumela oseduze we-high-frequency current ngemva kokuba ipuleti lekhoyili eligoqelwe elishisayo lenziwe umshini wokubumba, futhi umkhawulo weshubhu elingenalutho liyashiswa futhi liyancibilika, futhi ukushiswa kwengcindezi kwenziwa ngaphansi kwesenzo se-roller ecindezelayo ukuze uqaphele ukukhiqizwa. Ipayipi lensimbi elihlanganisiwe le-high-frequency resistance lihlukile kunenqubo evamile yokushisela ipayipi. I-weld yenziwe ngezinto eziyisisekelo zomzimba we-steel strip, futhi amandla omshini angcono kunalawo wepayipi elishiselwe jikelele. Ingaphezulu libushelelezi, linemba kakhulu, libiza kancane, futhi linobude obuphansi be-weld seam, okuzuzisa ukumbozwa kwe-3PE anti-corrosion coating.
▇ ▍Ipayipi Lensimbi LSAW
I-arc engaphansi kwe-longitudinal eshiselwe ikhiqizwa ngokusebenzisa ipuleti elilodwa eliphakathi nendawo neliwugqinsi njengempahla eluhlaza, ukucindezela (ukugingqa) ipuleti lensimbi esikhunjeni noma umshini wokwakha libe ishubhu elingenalutho, kusetshenziswa ukushisela kwe-arc okunezinhlangothi ezimbili, nokwandisa ububanzi. Inani lokuphakelayo kwepuleti lensimbi lingalungiswa ngokuzenzakalela ngokuya ngamamaki ensimbi ahlukene, ubukhulu bodonga, nobubanzi bepuleti. Ngesikhathi esifanayo, umsebenzi wokunxeshezelwa kwe-deformation ugwema ngokuphumelelayo imiphumela emibi ye-mold deformation ekubunjweni futhi iqinisekisa ukugcwala kobude obugcwele bepuleti yensimbi phakathi nenqubo yokucindezela. Isinyathelo sokuphakela siyafana ngesikhathi sokubunjwa, siqinisekisa ukuzungeza kweshubhu elingenalutho kanye nokucaba konqenqema lokushisela. Umkhiqizo oqediwe unezinhlobonhlobo zokucaciswa, futhi i-weld inokuqina okuhle, ipulasitiki, ukufana, nokubumbana. Inezinzuzo zobubanzi bepayipi elikhulu, ukushuba kodonga lwamapayipi, ukumelana nengcindezi ephezulu, ukumelana nezinga lokushisa eliphansi, nokumelana nokugqwala okuqinile.
▇ ▍Ipayipi lensimbi le-SSAW
Ipayipi elishiselwe i-Spiral (ipayipi le-SSAW, elibizwa nangokuthi ipayipi le-HSAW). Ipayipi lakhiwe ubuchwepheshe be-arc welding obuyi-spiral submerged arc. Amapayipi ashiselwe ku-Spiral akhiwa kusetshenziswa amapuleti amancane noma amakhoyili ashisayo asongwe, okwehlisa izindleko zawo zokukhiqiza kakhulu. Umugqa wokushisela umumo njenge-helix. Inqubo yokushisela okuvunguzayo ivumela ukukhiqizwa kwamapayipi anobubanzi obukhulu afanele ukuthuthwa umthamo omkhulu kawoyela negesi. Amanye amapayipi e-SSAW ngokomlando ayekhawulelwe ezinhlelweni zokucindezela okuphansi.
