Ipayipi Lensimbi Elishiselwe Longitudinally Submerged (LSAW)

Incazelo emfushane:

Ipayipi le-LSAW yipayipi Longitudinal Submerged Arc Welding.

Ubuchwepheshe bokukhiqiza bepayipi le-LSAW buyavumelana nezimo, futhi bungakhiqiza imininingwane namamodeli angakwazi ukukhiqizwa ngepayipi lensimbi elivama kakhulu, ipayipi lensimbi elivunguzayo kanye nepayipi lensimbi elingenamthungo.

Isetshenziswa kanjani i-LSAW Welded Steel Pipe For Pipelines

Insimbi eyisisekelo kanye nensimbi yokushisela ihlolwe ngokuvumelana nokucaciswa kwepayipi API SPEC 5L, DIN, EN, ASTM, GOST standard kanye nezinye izindinganiso.

Futhi, ipayipi le-LSAW lingashiswa ngama-flanges, ukuphakamisa amehlo nezinye izingxenye kuye ngezidingo zamakhasimende.

Ipayipi le-LSAW lisetshenziselwa ukudlulisa uketshezi olufana nowoyela, igesi kanye nokuthuthwa kwamanzi kanye nokusetshenziselwa amaphrojekthi ogwini lolwandle nokwakhiwa komhlabathi.Le mikhiqizo ikhiqizwa e-China futhi ithunyelwa kwamanye amazwe afana ne-United States of America, Canada, India, Pakistan, Africa, njll.

Inqubo Yokukhiqiza Ipayipi Lensimbi ye-LSAW

Inqubo yokukhiqiza ipayipi elikhulu lensimbi ye-LSAW 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.
