I-LSAW (I-Longitudinal double submerge arc welding)carbon steel pipewuhlobo lweIpayipi le-SAWezenziwe ngamapuleti ensimbi ayeshisa agingqiwe yi-JCOE noma i-UOE yokwakha ubuchwepheshe.Ubuchwepheshe be-JCOE bumele izinqubo zokubumba nokwakheka ezihilelekile ngesikhathi sokukhiqiza kanye nokushisela kwangaphakathi nangaphandle kanye nokunwetshwa okubandayo okwenziwa ngemva kokushisela.
Uma kuqhathaniswa ne-UOEAmapayipi ensimbi e-LSAW, abakhiqizi bamapayipi e-LSAW e-China bangakhiqiza osayizi abaningi ngale ndlela: OD 406 mm - 1620 mm, ukujiya 6.35 mm - 60 mm, ubude bepayipi 2 m - 18 m ngeIpayipi le-LSAWukuba nokuphakama.
- Inqubo yokukhiqiza ipayipi lensimbi ye-LSAW
Idatha ye-LSAWipayipi elikhulu lensimbi eliwububanziinqubo yokukhiqiza ichazwa ngezinyathelo ezingezansi:
1. I-Plate Probe: Lokhu kusetshenziselwa ukukhiqiza amajoyinti amakhulu e-LSAW angudayamitha ngemva nje kokuba ingene emgqeni wokukhiqiza okuwukuhlolwa kokuqala kwe-ultrasonic egcwele ibhodi.
2. Ukugaywa: Umshini osetshenziselwa ukugaya wenza lo msebenzi ngepuleti lokugaya elinezinhlangothi ezimbili ukuze uhlangabezane nezimfuneko zobubanzi bepuleti kanye nezinhlangothi ezihambisana nokuma kanye nezinga.
3. Uhlangothi olugobile ngaphambili: Lolu hlangothi lufinyelelwa ngokusebenzisa umshini ogoba ngaphambili onqenqemeni lwepuleti lokugoba ngaphambili.Unqenqema lwepuleti ludinga ukuhlangabezana nemfuneko yokugoba.
4. Ukwakha: Ngemva kwesinyathelo sokugoba ngaphambili, engxenyeni yokuqala yomshini wokubumba i-JCO, ngemva kwensimbi egxiviziwe, icindezelwa kusimo esithi “J” kuyilapho ngakolunye uhhafu wepuleti elifanayo lensimbi liyagotshwa futhi licindezelwe. ibe yisimo esithi “C”, bese ukuvuleka kokugcina kwenza umumo othi “O”.
5. I-Pre-welding: Lokhu ukwenza insimbi yepayipi elishiselwe ibe umthungo oqondile ngemva kokwakhiwa bese usebenzisa i-gas welding seam (MAG) ukushisela okuqhubekayo.
6. I-weld yangaphakathi: Lokhu kwenziwa nge-tandem ye-arc yensimbi enezintambo eziningi ezishiselwe (cishe izintambo ezine) engxenyeni engaphakathi yomthungo oqondile wepayipi lensimbi.
7. Ukushisela Ngaphandle: I-weld yangaphandle iwukushisela i-arc enezintambo eziningi ezingaphansi kwe-tandem engxenyeni engaphandle ye-LSAW yensimbi yokushisela ipayipi.
8. Ukuhlolwa kwe-Ultrasonic: Ngaphandle nangaphakathi komthungo oqondile wepayipi lensimbi elishiselwe futhi izinhlangothi zombili zezinto eziyisisekelo zishiselwe ngokuhlolwa okungu-100%.
9. Ukuhlolwa kwe-X-ray: Ukuhlolwa kwe-TV yezimboni ze-X-ray kwenziwa ngaphakathi nangaphandle kusetshenziswa isistimu yokucubungula izithombe ukuze kuqinisekiswe ukuthi kukhona ukuzwela kokutholwa.
10. Ukunwetshwa: Lokhu okokufeza ukushiselwa kwe-arc engaphansi kwamanzi kanye nobubanzi bepayipi lensimbi yomthungo oqondile ukuze kuthuthukiswe ukunemba kosayizi weshubhu lensimbi futhi kuthuthukiswe ukusatshalaliswa kokucindezeleka eshubhuni lensimbi.
11. Ukuhlolwa kwe-Hydraulic: Lokhu kwenziwa emshinini wokuhlola we-hydraulic wensimbi ngemuva kokwandisa ukuhlolwa kwezimpande zokuqinisekisa ukuthi ipayipi lensimbi lihlangabezana nezidingo ezijwayelekile ngomshini onekhono lokurekhoda ngokuzenzakalela nokugcina.
12. I-Chamfering: Lokhu kuhilela ukuhlolwa okwenziwa epayipini lensimbi ekupheleni kwayo yonke inqubo.
