▇ ▍ 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 ovamile noma ukwakheka kwesikwele.Ipayipi LSAW, ipayipi le-SSAW kanye nepayipi le-ERW wonke amapayipi ensimbi ashiselwe futhi ahlukaniswa ngokusekelwe indlela ye-welding.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 ama-high-frequency ajwayelekile a-straight-slit, kodwa amapayipi ensimbi ane-strat-slit ashiselwe awasho ukuthi ashiselwe imvamisa ephezulu.I-high-frequency straight-slit ukumelana kagesi eshiselwe ipayipi lensimbi lakhiwa umphumela wesikhumba kanye nomphumela oseduze we-high-frequency yamanje ngemva kokuba ipuleti lekhoyili eligoqelwe elishisayo lakhiwe umshini wokubumba, futhi umkhawulo we-tube ungenalutho. kushise futhi kuncibilike, futhi i-pressure welding yenziwa ngaphansi kwesenzo se-roller ecindezelayo ukuze ibone 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 ngokuzenzakalelayo 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, ukujiya kodonga lwamapayipi, ukumelana nokucindezela okuphezulu, 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.
