Ipayipi lensimbi elivunguzayo lisezingeni eliphezulu futhi lentengo ephansi
Ipayipi lensimbi elivunguzayo liyipayipi lensimbi elivunguzayo elenziwe ngekhoyili yensimbi eyi-strip njengempahla eluhlaza, evame ukwakhiwa nge-extrusion efudumele futhi eshiselwe inqubo yokushisela ye-arc enezintambo eziphindwe kabili emaceleni. Ipayipi lensimbi elivunguzayo lithumela insimbi yomugqa kuyunithi yepayipi elishiselwe. Ngemva kokugingqika ngama-roller amaningi, insimbi ye-strip igoqwa kancane kancane ukuze yakhe ipayipi eliyindilinga elingenalutho elinegebe elivulekayo. Lungisa ukuncishiswa kwerola ye-extrusion ukuze ulawule igebe lokushisela ku-1 ~ 3mm futhi wenze zombili iziphetho ze-weld junction ziguqe.
(1) Izinto zokusetshenziswa, okungukuthi ikhoyili yensimbi, intambo yokushisela kanye ne-flux. Ukuhlolwa okuqinile ngokomzimba namakhemikhali kuyokwenziwa ngaphambi kokufaka.
(2) I-butt ye-strip steel head kanye nomsila isebenzisa i-arc welding eyodwa noma izintambo ezimbili ezingaphansi kwamanzi, futhi ukushisela okuzenzakalelayo kwe-arc okuzenzakalelayo kwamukelwa ukuze kulungiswe ukushiselwa ngemva kokugingqika epayipini lensimbi.
(3) Ngaphambi kokwakhiwa, insimbi ye-strip iyalinganiswa, iyasikwa, ihlelwe, ihlanzwe, ithuthwe futhi igotshwe ngaphambili.
(4) Igeji yokulinganisa ingcindezi kagesi isetshenziselwa ukulawula ingcindezi yesilinda samafutha esicindezelayo ezinhlangothini zombili zomthumeli ukuze kuqinisekiswe ukuthuthwa okubushelelezi kwe-strip steel.
(5) Yamukela isilawuli sangaphandle noma ukwakhiwa komqulu wokulawula wangaphakathi.
(6) Idivayisi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe lokushisela lihlangabezana nezidingo zokushisela, futhi ububanzi bepayipi, ukungahambi kahle kanye negebe lokushisela kulawulwa ngokuqinile.
(7) Kokubili ukushisela kwangaphakathi nokushisela kwangaphandle kusebenzisa umshini wokushisela we-American Lincoln Electric wocingo olulodwa noma i-arc welding enezintambo ezimbili ezingaphansi kwamanzi, ukuze kutholwe ikhwalithi yokushisela ezinzile.
(8) Wonke ama-weld ashiselwe ahlolwa ngomtshina oqhubekayo we-ultrasonic othomathikhi we-inthanethi ukuze kuqinisekiswe ukumbozwa kwe-NDT okungu-100% kwama-spiral weld. Uma kukhona ukukhubazeka, kuzokuxwayisa ngokuzenzakalelayo futhi kufake amamaki, futhi izisebenzi zokukhiqiza zizolungisa imingcele yenqubo nganoma yisiphi isikhathi ukuze kuqedwe ukukhubazeka ngesikhathi.
(9) Ipayipi lensimbi lisikwa libe yizicucu zodwa ngomshini wokusika i-plasma yomoya.
(10) Ngemva kokusika epayipini elilodwa lensimbi, iqoqo ngalinye lepayipi lensimbi kufanele libe ngaphansi kwesistimu yokuhlola yokuqala eqinile ukuze kuhlolwe izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana, izinga eliphezulu lepayipi lensimbi kanye ne-NDT ukuze kuqinisekiswe ukuthi ukwenziwa kwepayipi. inqubo iyafaneleka ngaphambi kokuthi ifakwe ngokusemthethweni ekukhiqizweni.
(11) Izingxenye ezinamamaki okuthola amaphutha e-acoustic okuqhubekayo ku-weld zizohlolwa kabusha nge-manuwali ultrasonic ne-X-ray. Uma kuneziphambeko, ngemva kokulungiswa, zizophinde zibe ngaphansi kwe-NDT kuze kube yilapho kuqinisekiswa ukuthi amaphutha asusiwe.
(12) Ipayipi le-butt welding seam ye-strip steel kanye ne-T-joint intersecting spiral weld izohlolwa ngomabonakude we-X-ray noma ifilimu.
(13) Ipayipi ngalinye lensimbi lingaphansi kokuhlolwa kwe-hydrostatic, futhi ingcindezi ithatha uphawu lwe-radial. Ingcindezi yokuhlola kanye nesikhathi kulawulwa ngokuqinile yidivayisi yokuthola i-microcomputer yokucindezela kwamanzi epayipi lensimbi. Imingcele yokuhlola iphrintwa futhi irekhodwe ngokuzenzakalelayo.
(14) Isiphetho sepayipi senziwa ngomshini ukuze kulawulwe ngokunembile i-perpendicularity, i-engeli yeslope kanye nonqenqema olubuthuntu lobuso bokuphela.
1. Uma igebe likhulu kakhulu, umphumela wokusondela uzoncishiswa, ukushisa kwamanje kwe-eddy ngeke kwanele, futhi i-weld intergranular joint izoba mbi, okuholela ekuhlanganiseni okungaphelele noma ukuqhekeka.
2.Uma igebe lincane kakhulu, umphumela wokusondeza uzokwanda, ukushisa kwe-welding kuyoba kukhulu kakhulu, futhi i-weld izoshiswa; Noma i-weld ikhishwa futhi igoqwe ukuze yakhe umgodi ojulile, othinta izinga eliphezulu le-weld.
Ngemuva kokuthi imiphetho emibili ye-tube engenalutho ishiselwe ekushiseni okushiselayo, okusanhlamvu okujwayelekile kwensimbi kwakhiwa ngaphansi kwe-extrusion ye-roller extrusion, engena futhi icwebezelisa omunye nomunye, futhi ekugcineni yakha i-weld eqinile. Uma i-extrusion force ye-spiral steel pipe incane kakhulu, inani lamakristalu avamile liyoba lincane, amandla ensimbi ye-weld azokwehla, futhi ukuqhekeka kuzokwenzeka ngemva kokucindezeleka; Uma amandla e-extrusion makhulu kakhulu, insimbi encibilikisiwe izokhishwa ngaphandle kwe-weld, engeke inciphise amandla e-weld kuphela, kodwa futhi ikhiqize inani elikhulu lama-burrs angaphakathi nangaphandle, futhi abangele ngisho nokukhubazeka okufana nokunqwabelana kwe-welding.
