Ipayipi Lensimbi Elisezingeni Eliphezulu
Ipayipi Lensimbi Elisezingeni Eliphezulu
Izinto ezisetshenziswa kakhulu zamapayipi okuvunguza e-China ngokuvamile zihlanganisa: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni1cn18ni18ni1Amazinga avamile amapayipi Kuvunguza ngokuvamile ahlukaniswe: SY / t5037-2018 (izinga likangqongqoshe, eyaziwa nangokuthi spiral uthungo submerged arc welded steel pipe for avamile uketshezi transmission pipeline), GB / T9711.1-1997 (standard kazwelonke, eyaziwa nangokuthi izimo zobuchwepheshe zokulethwa kwepayipi lensimbi lokudlulisa embonini kawoyela negesi, ingxenye I: isigaba sepayipi lensimbi (GB / t9711.2 ipayipi lensimbi lesigaba B elinezidingo eziqinile)), i-api-5l (i-American Petroleum Association, eyaziwa nangokuthi ipayipi lensimbi yepayipi );Kubandakanya i-PSL1 ne-PSL2), i-SY / t5040-92 (ipayipi lensimbi elihlanganisiwe le-arc elihlanganisiwe lenqwaba).
(1) izinto zokusetshenziswa, okungukuthi i-strip steel coil, i-welding wire kanye ne-flux.Ukuhlolwa okuqinile ngokomzimba namakhemikhali kuyokwenziwa ngaphambi kokufaka
(2) Ijoyinti lezinqe lekhanda nomsila wensimbi lithatha intambo eyodwa noma izintambo ezimbili ezingaphansi kwe-arc welding, futhi ukushiselwa kwe-arc okuzenzakalelayo okungaphansi kwamanzi kwamukelwa ukuze kulungiswe ukushiselwa ngemva kokugingqika epayipini lensimbi.
(3) Ngaphambi kokwakhiwa, insimbi ye-strip iyalinganiswa, inqunywe, ihlelwe, ihlanzwe, ihanjiswe futhi igotshwe ngaphambili.
(4) Igeji yokulinganisa ingcindezi kagesi isetshenziselwa ukulawula ingcindezi yesilinda samafutha esicindezelayo nhlangothi zombili zomthumeli ukuqinisekisa ukuthuthwa okubushelelezi kwe-strip steel.
(5) Yamukela isilawuli sangaphandle noma ukwakhiwa komqulu wokulawula wangaphakathi
(6) Idivaysi yokulawula igebe lokushisela isetshenziselwa ukuqinisekisa ukuthi igebe lokushisela liyahlangabezana nezidingo zokushisela, futhi ububanzi bepayipi, ukungahambi kahle kanye negebe lokushisela kulawulwa ngokuqinile.
(7) Kokubili ukushisela kwangaphakathi nokushisela kwangaphandle kusebenzisa umshini wokushisela i-American Lincoln Electric wocingo olulodwa noma ngocingo oluphindwe kabili olucwiliswe yi-arc welding, ukuze kutholwe ukucaciswa kokushisela okuzinzile.
(8) Wonke ama-weld ashiselwe ahlolwa ngomtshina oqhubekayo we-ultrasonic othomathikhi we-inthanethi ukuze kuqinisekiswe ukumbozwa kwe-NDT okungu-100% kwama-spiral weld.Uma kuneziphambeko, izokhala ngokuzenzakalelayo futhi ifafaze amamaki, futhi izisebenzi zokukhiqiza zizolungisa imingcele yenqubo nganoma yisiphi isikhathi ukuze kuqedwe amaphutha 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 zizobhekwa kabusha nge-manuwali ultrasonic ne-X-ray.Uma kuneziphambeko, ngemuva kokulungiswa, zizophinde zibe ngaphansi kwe-NDT kuze kuqinisekiswe 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 idivayisi yokutholwa kwe-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.Ipayipi elishiselwe i-Spiral seam elingaphansi kwe-arc lokuthuthwa koketshezi olucindezelayo lisetshenziselwa ikakhulukazi amapayipi athutha uwoyela negesi yemvelo.
Ipayipi lensimbi linomthamo oqinile wokuthwala ingcindezi kanye nepulasitiki enhle, elungele ukushisela nokucubungula;I-Spiral seam engaphansi kwe-arc welded steel pipe yokudlulisa uketshezi olunomfutho ophansi ojwayelekile yenziwa ngokushisela i-arc enezinhlangothi ezimbili ezizenzakalelayo noma indlela yokushisela ohlangothini olulodwa, esetshenziselwa ukudlulisa uketshezi olunengcindezi ephansi njengamanzi, igesi, umoya nesitimu. .
Ipayipi elihlanganisiwe le-seam eliqondile linezinzuzo zenqubo yokukhiqiza elula, ukusebenza kahle kokukhiqiza okuphezulu, izindleko eziphansi kanye nentuthuko esheshayo.Amandla epayipi elishiselwe okuvunguza ngokuvamile aphakeme kunalawo amapayipi ashiselwe aqondile.Ingakhiqiza ipayipi elishiselwe elinobubanzi bepayipi elikhudlwana elingenalutho eliwumngcingo, kanye nepayipi elishiselwe elinobubanzi bepayipi elihlukene elingenalutho lobubanzi obufanayo.Nokho, uma kuqhathaniswa nepayipi lomthungo eliqondile elinobude obufanayo, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi.Ngakho-ke, i-seam welding eqondile isetshenziswa kakhulu kumapayipi ashiselwe anobubanzi obuncane, futhi ukushisela okuvunguzayo kusetshenziswa kakhulu kumapayipi ashiselwe anobubanzi obukhulu.Ipayipi elivunguzayo lisetshenziswa kakhulu kubunjiniyela bamanzi kampompi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo kanye nokwakhiwa kwamadolobha.Ingenye yemikhiqizo engu-20 ebalulekile eyakhiwe eShayina.Okokuthutha okuwuketshezi: ukuhlinzekwa kwamanzi, ukuthuthwa kwamanzi, ubunjiniyela bokuhlanza indle, ukuthuthwa ngodaka, ukuthuthwa kwamanzi olwandle.Ngokudluliswa kwegesi: igesi, isitimu kanye negesi ye-petroleum ewuketshezi.Ngokwesakhiwo: njengepayipi lokushayela inqwaba nebhuloho;Amapayipi echweba, umgwaqo kanye nezakhiwo zokwakha, amapayipi okunqwabelanisa olwandle, njll.
