Ipayipi lensimbi elivunguzayo liyipayipi lensimbi elivunguzayo elenziwe ngekhoyili yensimbi eyi-strip njengempahla eluhlaza, ekhishwa ngezinga lokushisa elivamile, futhi elishiselwe inqubo yokushisela engaphansi kwe-arc enezintambo ezimbili emaceleni ezenzakalelayo.Ipayipi lensimbi elivunguzayo lithumela insimbi ye-strip kuyunithi yepayipi elishiselwe, futhi ngemva kokugingqika ngamarola amaningi, insimbi yomugqa igoqwa kancane kancane ukuze yakhe i-billet yeshubhu eliyindilinga elinegebe elivulekayo.Lungisa ukuncishiswa kwerola ye-extrusion ukuze ulawule igebe lomthungo we-weld libe ngu-1~ 3mm, futhi wenze iziphetho zombili zembobo yokushisela ziguqe.
Inqubo Yokukhiqiza
(1) Izinto ezisetshenziswayo amakhoyili ensimbi ehlutshiwe, izintambo zokushisela, nezinsimbi.Ngaphambi kokuba zisetshenziswe, kufanele zihlolwe ngokuqinile ngokomzimba namakhemikhali.
(2) I-head-to-tail joint butt ye-strip steel ithatha i-arc welding enocingo olulodwa noma i-double-wire submerged arc welding, futhi i-arc engaphansi kwamanzi isetshenziselwa ukulungisa ukushisela ngemva kokugoqwa emapayipini ensimbi.
(3) Ngaphambi kokwakhiwa, insimbi ye-strip iyalinganiswa, inqunywe, ihlelwe, ihlanzeke, ihanjiswe futhi igotshwe ngaphambili.
(4) Izikali zokucindezela kokuxhumana ngogesi zisetshenziselwa ukulawula ukucindezela kwamasilinda nhlangothi zombili zesithumeli sokuhambisa ukuze kuqinisekiswe ukudluliswa kahle komugqa.
(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 i-welding yangaphakathi ne-welding yangaphandle isebenzisa umshini wokushisela we-American Lincoln wocingo olulodwa noma i-double-wire submerged arc welding, ukuze kutholwe izinga lokushisela elizinzile.
(8) Ama-seam ashiselwe wonke ahlolwa umtshina we-inthanethi oqhubekayo we-ultrasonic othomathikhi, oqinisekisa ukumbozwa kokuhlola okungabhubhisi okungu-100% kwama-spiral weld.Uma kunesici, kuzokwethusa ngokuzenzakalelayo futhi kufafaze uphawu, futhi izisebenzi zokukhiqiza zingalungisa imingcele yenqubo nganoma yisiphi isikhathi ngokusho kwalokhu ukuze kuqedwe iphutha ngesikhathi.
(9) Sebenzisa umshini wokusika i-plasma yomoya ukuze usike ipayipi lensimbi libe yizicucu eyodwa.
(10) Ngemva kokusika amapayipi ensimbi eyodwa, iqoqo ngalinye lamapayipi ensimbi kufanele ahlolwe kuqala ukuze ahlole izakhiwo zemishini, ukwakheka kwamakhemikhali, isimo sokuhlangana kwamapayipi okushisela, izinga eliphezulu lepayipi lensimbi kanye nokuhlolwa okungacekeleki phansi ukuze kuqinisekiswe ukuthi inqubo yokwenza amapayipi ifanelekile Emva kwalokho, ingafakwa ngokusemthethweni ekukhiqizeni.
(11) Izingxenye ezimakwe ngokuqhubekayo kokutholwa kwamaphutha emshinini wokushisela zizohlolwa nge-ultrasonic manual kanye ne-X-ray kabusha.Uma kuneziphambeko ngempela, ngemva kokulungiswa, zizophinde zihlolwe ngokungekonakali kuze kube yilapho kuqinisekiswa ukuthi iziphambeko zizoqedwa.
(12) Amapayipi lapho kushiselwa khona izinqe zensimbi kanye namajoyinti e-D aphambana nezinto zokushisela okuvunguzayo konke ahlolwe nge-X-ray TV noma ifilimu.
(13) Ipayipi ngalinye lensimbi liphumelele ukuhlolwa kwengcindezi ye-hydrostatic, futhi ingcindezi ivalwe nge-radially.Ingcindezi yokuhlola nesikhathi kulawulwa ngokuqinile ipayipi lensimbi lokutholwa kwamanzi okucindezela i-microcomputer idivayisi.Imingcele yokuhlola iphrintwa futhi irekhodwe ngokuzenzakalelayo.
(14) Isiphetho sepayipi senziwa ngomshini ukuze kulawulwe ngokunembile ukuma kobuso bokuphela, i-engeli ye-bevel kanye nonqenqema olubuthuntu.
Ukwelashwa kwe-weld
1. Uma igebe likhulu kakhulu, umphumela wokusondeza uzoncishiswa, ukushisa kwe-eddy current ngeke kwanele, futhi ukubopha kwe-intergranular kwe-weld kuyoba kubi, okuholela ekuntuleni ukuhlanganisa noma ukuqhekeka.
2. Uma igebe lincane kakhulu, umphumela wokusondeza uzokwanda, ukushisa kwe-welding kuyoba kukhulu kakhulu, futhi i-weld seam izoshiswa;noma i-weld seam izokwakha imigodi ejulile ngemva kokukhishwa nokugingqika, okuzothinta ikhwalithi engaphezulu ye-weld seam.
Ngemuva kokuthi imiphetho emibili ye-tube engenalutho ishiselwe ekushiseni kwe-welding, ngaphansi kwe-extrusion ye-roller extrusion, okusanhlamvu okujwayelekile kwensimbi kwakhiwa ukuze kungene futhi kucwebezele komunye nomunye, futhi ekugcineni kwakheke i-weld eqinile.Uma amandla e-extrusion wepayipi lensimbi elivunguzayo lincane kakhulu, inani lamakristalu avamile akhiwe liyoba lincane, amandla ensimbi ye-weld azokwehla, futhi imifantu izokwenzeka ngemva kokucindezelwa;uma i-extrusion force inkulu kakhulu, insimbi encibilikisiwe izocindezelwa ngaphandle kwe-weld, ayinciphisi kuphela amandla we-weld seam, kodwa futhi ikhiqiza inani elikhulu lama-burrs angaphakathi nangaphandle, futhi ibangele ngisho nokukhubazeka okufana ne-weld laps. .
Izici zenqubo
Izici eziyinhloko zenqubo yepayipi lensimbi elivunguzayo:
a.Phakathi nenqubo yokwenza, ukuguqulwa kwepuleti yensimbi kufana, ukucindezeleka okusalayo kuncane, futhi ubuso abukhiqizi imihuzuko.Ipayipi lensimbi elivunguzayo elicutshunguliwe linokuguquguquka okukhulu kusayizi nobubanzi bemininingwane yobubanzi nokuqina kodonga, ikakhulukazi ekukhiqizeni amapayipi anezindonga eziwugqinsi wezinga eliphezulu, ikakhulukazi amapayipi anodonga oluwugqinsi olunobubanzi obumaphakathi.Kunezidingo ezengeziwe mayelana nokucaciswa kwepayipi lensimbi elivunguzayo.
b.Ukusebenzisa ubuchwepheshe bokushisela be-arc obunezinhlangothi ezimbili obusezingeni eliphezulu, ukushisela kungenziwa endaweni engcono kakhulu, futhi akulula ukuba namaphutha njengokungahambi kahle, ukuchezuka kwe-welding kanye nokungena okungaphelele, futhi kulula ukulawula ikhwalithi yokushisela.
c.Yenza ukuhlolwa kwekhwalithi engu-100% yamapayipi ensimbi, ukuze yonke inqubo yokukhiqizwa kwamapayipi ensimbi ibe ngaphansi kokuhlolwa okusebenzayo nokuqapha, ukuqinisekisa ngempumelelo ikhwalithi yomkhiqizo.
d.Zonke izinto zokusebenza zalo lonke umugqa wokukhiqiza zinomsebenzi wokuxhumana nohlelo lokutholwa kwedatha yekhompiyutha ukuze kubonakale ukudluliswa kwedatha yesikhathi sangempela, futhi imingcele yezobuchwepheshe enqubweni yokukhiqiza ihlolwe yigumbi lokulawula eliphakathi.
