Ipayipi lensimbi ngokuvamile lihlukaniswe libe ipayipi lensimbi elingenamthungo kanye nepayipi lensimbi elishiselwe ngokuvumelana nezindlela zokukhiqiza.Ngalesi sikhathi sethula ikakhulukazi ipayipi lensimbi elishiselwe, okungukuthi, ipayipi lensimbi elishiselwe. Ukukhiqizwa kwalo ukugoba ishubhu lingenalutho (ipuleti lensimbi nomugqa wensimbi endaweni edingekayo ye-cross-section shape kanye neshubhu yosayizi ngezindlela ezahlukahlukene zokwakha, bese sishisela i-weld. ngezindlela ezahlukene zokushisela ukuze uthole ipayipi lensimbi.
Uma kuqhathaniswa nepayipi lensimbi elihlanganisiwe elingenamthungo, linomkhiqizo onembile onezici zokunemba okuphezulu, ikakhulukazi ukushuba kodonga oluphakeme.imishini elula eyinhloko, indawo encane yaphansi, ukusebenza okuqhubekayo ekukhiqizeni nasekukhiqizeni okuguquguqukayo, ipayipi elishiselwe lingahlukaniswa libe spiralipayipi elishiselwe i-arc elingaphansi, umthungo oqondile onamacala amabili afakwe ngaphansi kwe-arc ipayipi elishiselwe kanye nepayipi elishiselwe ukumelana.
1.Inqubo yokukhiqiza ipayipi lensimbi elivunguzayo imi kanje:
Izinto zokusetshenziswa zepayipi lensimbi elivunguzayo yikhoyili ehlutshiwe, intambo yokushisela kanye ne-flux.ithuthwa phezulu, futhi igobile.Idivayisi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe lokushisela liyahlangabezana nezidingo zokushisela.Ububanzi bepayipi, ukungalungi kahle kanye negebe lokushisela kulawulwa ngokuqinile. Ngemva kokusika epayipini elilodwa lensimbi amathathu okuqala eqoqweni ngalinye lamapayipi ensimbi angaphansi kwesistimu yokuhlola yokuqala eqinile, ukuze kuhlolwe izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana kanye izinga eliphezulu le-weld, kanye nokuhlola okungabhubhisi ukuze kuqinisekiswe ukuthi inqubo yokukhiqiza ipayipi ifanelekile.ingafakwa ngokusemthethweni ekukhiqizweni.
2.LSAW ipayipi:
Ngokuvamile, ipayipi le-LSAW lenziwe ngepuleti lensimbi ngokusebenzisa izinqubo ezahlukene zokwakha, njengokushisela okungaphansi kwe-arc okunezinhlangothi ezimbili kanyeukwanda ngemva kokushisela.Izindlela zokwakha ipayipi le-LSAW zihlanganisa uo(UOE),Rb(RBE),JCO(JCOE), njll.
Ukwakhiwa kwepayipi le-UOE LSAW:
Inqubo yokwakhiwa kwepayipi elishiselwe i-arc longitudinal le-UOE longitudinal elingaphansi kwamanzi lihlanganisa ikakhulukazi izinqubo ezintathu zokwakha: ipuleti lensimbi ngaphambi kokugoba, ukwakheka no-O ukwakha.Inqubo ngayinye isebenzisa umshini wokunyathelisa okhethekile wokunyathelisa ukuze kuqedelwe izinqubo ezintathu ze-steel plate edge pre bending, u-ukwakheka kanye nokwakheka kwe-O ukuze kukhubazeke ipuleti lensimbi libe ishubhu eliyindilinga.Inqubo yokwenza i-JCOE longitudinal submerged arc ipayipi elishiselwe: ngo-jc0 Ngemva ukugxiviza okuphindaphindiwe emshinini wokwenza, ingxenye yokuqala yepuleti lensimbi icindezelwa kumumo ka-J, bese enye ingxenye yensimbi icindezelwe ibe umumo ongu-J ukuze kwakheke umumo ongu-C.
Ukuqhathaniswa kwe-JCO nezindlela zokubumba ze-uo:
Ukwakhiwa kwe-JCO kuwukwakha ukucindezela okuqhubekayo., okushintsha inqubo yokwenza ipayipi lensimbi lisuka ezinyathelweni ezimbili ze-UO kwakheka izinyathelo eziningi.Enqubweni yokwakha, ipuleti lensimbi linokuguqulwa okufanayo, ukucindezeleka okuncane okuyinsalela futhi akukho nokuklwebheka phezulu.Ipayipi lensimbi elicutshunguliwe linokuguquguquka okukhulu kububanzi bobukhulu bobubanzi nobukhulu bodonga.Ingakhiqiza imikhiqizo eminingi kanye nenani elincane lemikhiqizo.kanye nemikhiqizo yezinga elikhulu nekhwalithi ephezulu Ingakhiqiza futhi ububanzi obuncane namapayipi amakhulu ensimbi odongeni.ikakhulukazi ekukhiqizweni kwamapayipi odonga aminyene asezingeni eliphezulu ikakhulukazi ekukhiqizeni amapayipi odonga awugqinsi nobubanzi obuncane.Inezinzuzo ezingenakuqhathaniswa kunezinye izinqubo, futhi ingahlangabezana nezidingo ezengeziwe zabasebenzisi zokucaciswa kwepayipi lensimbi.Ukubumba kwe-Uo kwamukela u-u kanye no-O wezinyathelo ezimbili zokwakha ingcindezi, ebonakala ngomthamo omkhulu nokukhishwa okuphezulu.Ngokuvamile, okukhiphayo konyaka kungafinyelela ku-30 -30% amathani ayizigidi ezi-1, alungele ukukhiqizwa okukodwa okukodwa.
3. Umthungo oqondile ipayipi elihlanganisiwe lemvamisa ephezulu
Ipayipi elishiselwe i-seam high frequency welded (ERW) lakhiwa ngokushisisa unqenqema lwe-tube billet ngomphumela wesikhumba kanye nomphumela oseduze we-high frequency current ngemuva kokuba ikhoyili egoqwe eshisayo ibunjwe umshini wokwakha, bese ukushiselwa kwengcindezi kuyenziwa. ngaphansi kwesenzo se-roller extrusion.
