Ipayipi lensimbi elivunguzayo lenziwa ngokugingqa insimbi yesakhiwo enekhabhoni ephansi noma umucu wensimbi yesakhiwo esinengxubevange ephansi ibe yipayipi , ngokuya nge-engeli ethile yomugqa ovunguzayo (okuthiwa i-engeli yokubumba), bese kushiselwa imiphetho yamapayipi.
Ingasetshenziselwa ukukhiqiza ipayipi elikhulu lensimbi eliwububanzi ngensimbi ewumngcingo.
Ukucaciswa kwepayipi lensimbi elivunguzayo kuvezwa ubukhulu bangaphandle * bodonga.
Ipayipi elishiselwe kufanele lihlolwe ngokuhlolwa kwe-hydrostatic, amandla aqinile kanye nokugoba okubandayo, ukusebenza komthungo wokushisela kuzohlangabezana nezidingo zokucaciswa.
Injongo eyinhloko:
Ipayipi lensimbi elivunguzayo lisetshenziselwa ikakhulukazi ukuhambisa uwoyela negesi yemvelo.
Inqubo yokukhiqiza:
(1) Izinto ezisetshenziswayo: ikhoyili yensimbi, intambo yokushisela kanye ne-flux.Ukuhlolwa okuqinile ngokomzimba namakhemikhali kuyokwenziwa ngaphambi kokukhiqiza.
(2) Isinqe esishisela ikhanda nomsila wekhoyili ukwenza amakhoyili amabili ahlangane, bese sithatha ucingo olulodwa noma izintambo ezimbili ezingaphansi kwe-arc welding, futhi ukushiselwa kwe-arc okuzenzakalelayo okungaphansi kwamanzi kwamukelwa ukushiselwa ngemva kokugingqika epayipini lensimbi.
(3) Ngaphambi kokwakhiwa, insimbi yomugqa kufanele ilinganiswe, inqunywe, ihlelwe, ihlanzeke, ithuthwe futhi igotshwe ngaphambili.
(4) Igeji yokulinganisa ingcindezi kagesi isetshenziselwa ukulawula ingcindezi yesilinda samafutha esicindezelayo ezinhlangothini zombili zomthumeli ukuze kuqinisekiswe ukuthuthwa kwensimbi ye-strip kahle.
(5) Ukwenza umqulu, sebenzisa isilawuli sangaphandle noma isilawuli sangaphakathi.
(6) Sebenzisa idivayisi yokulawula igebe lokushisela ukuze uqinisekise ukuthi igebe lokushisela lihlangabezana nezidingo zokushisela, khona-ke ububanzi bepayipi, ukungahambi kahle kanye negebe lokushisela kungalawulwa ngokuqinile.
(7) Kokubili ukushisela kwangaphakathi kanye nokushisela kwangaphandle kusebenzisa umshini wokushisela i-American Lincoln Electric wocingo olulodwa noma izintambo ezimbili ezingaphansi kwe-arc welding, ukuze kutholwe ukusebenza kokushisela okuzinzile.
(8) Wonke ama-welding seams ahlolwa ngomtshina oqhubekayo we-ultrasonic othomathikhi we-inthanethi ukuze kuqinisekiswe ukuhlolwa kwe-NDT okungu-100% okumboza yonke i-spiral welding seams.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 yisiqephu esisodwa ngomshini wokusika.
(10) Ngemva kokusika epayipini elilodwa lensimbi, iqoqo ngalinye lepayipi lensimbi liyoba ngaphansi kwesistimu yokuhlola eqinile yokuqala ukuze kuhlolwe izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana, izinga eliphezulu lepayipi lensimbi kanye ne-NDT ukuze kuqinisekiswe ukuthi inqubo yokwenza ipayipi iyafaneleka ngaphambi kokuthi ifakwe ngokusemthethweni ekukhiqizweni.
(11) Izingxenye ezinamamaki okuthola amaphutha e-acoustic okuqhubekayo kumthungo wokushisela kufanele zihlolwe kabusha nge-ultrasonic ultrasonic ne-X-ray.Uma kuneziphambeko, ngemva kokulungiswa, ipayipi izophinde ibe ngaphansi kwe-NDT kuze kube yilapho kuqinisekiswa ukuthi amaphutha asusiwe.
(12) Ipayipi lomthungo wokushisela izinqe kanye ne-T-joint intersecting spiral welding seam kufanele ihlolwe ngomabonakude we-X-ray noma ukuhlolwa kwefilimu.
(13) Ipayipi ngalinye lensimbi lingaphansi kokuhlolwa kwe-hydrostatic.Ingcindezi yokuhlola kanye nesikhathi kulawulwa ngokuqinile idivayisi yokutholwa kwekhompyutha yokucindezela kwamanzi epayipi lensimbi.Imingcele yokuhlola iphrintwa futhi irekhodwe ngokuzenzakalelayo.
(14) Isiphetho sepayipi senziwa ngomshini ukuze kulawulwe ngokunembile i-perpendicularity, i-bevel angle kanye nobuso bempande.
