LSAW (Longitudinal double submerge arc welding)kabhoni simbi pombiimhando yeSAW pombiyakagadzirwa nemahwendefa esimbi aipisa akakungurutswa neJCOE kana UOE kugadzira tekinoroji.JCOE tekinoroji inomiririra maumbirwo uye magadzirirwo anosanganisirwa panguva yekugadzira pamwe nemukati nekunze welding uye kutonhora kwekuwedzera kunoitwa mushure mekugadzira.
Kana ichienzaniswa neUOELSAW simbi mapaipi, LSAW vanogadzira pombi muChina vanogona kugadzira hukuru hwakawanda seizvi: OD 406 mm - 1620 mm, ukobvu 6.35 mm - 60 mm, urefu hwepombi 2 m - 18 m neLSAW pombikuva nehukuru.
- LSAW simbi yekugadzira pombi maitiro
Iye LSAWhombe dhayamita simbi pombinzira yekugadzira inotsanangurwa mumatanho ari pasi apa:
1. Plate Probe: Iyi inoshandiswa pakugadzira dhayamita yakakura LSAW majoini mushure mekunge yapinda mumutsara wekugadzira iyo yekutanga yakazara-bhodhi ultrasonic test.
2. Kugaya: Muchina unoshandiswa pakugaya unoita basa iri kuburikidza nendiro ine mativi maviri ekugaya kuti usangane nezvinodiwa zvehupamhi hweplate uye mativi anoenderana nechimiro nedhigirii.
3. Pre-curved side: Iri divi rinowanikwa nekushandisa pre-bending muchina pa-pre-bending plate edge.Mupendero weplate unoda kusangana nezvinodiwa curvature.
4. Kugadzira: Mushure mekutanga-kupeta nhanho, muhafu yekutanga yemuchina weJCO wekuumba, mushure mesimbi yakadhindwa, inotsikirirwa kuita "J" chimiro apo iyo kune imwe hafu yesimbi imwechete ndiro inokotama nekutsikirirwa. kupinda muchimiro che “C”, ipapo kuvhura kwekupedzisira kunoita “O” chimiro.
5. Pre-welding: Izvi ndezvekuita welded pipe simbi musono wakatwasuka mushure mekunge wagadzirwa uye wozoshandisa gas welding seam (MAG) yekuenderera mberi welding.
6. Mukati weld: Izvi zvinoitwa ne tandem multi-waya yakanyudzwa arc welding (inenge waya ina) pane yemukati chikamu cheyakatwasuka musono welded simbi pombi.
7. Kunze Weld: Kunze weld ndeye tandem yakawanda-waya yakanyudzwa arc welding pane chikamu chekunze cheLSAW simbi pombi welding.
8. Ultrasonic Testing: Kunze uye mukati meiyo yakatwasuka seam welded simbi pombi uye mativi maviri echigadziko zvinhu zvakashongedzwa ne100% yekuongorora.
9. X-ray kuongorora: X-ray indasitiri yekuongorora yeTV inoitwa mukati nekunze uchishandisa dhizaini yekugadzira mifananidzo kuti ive nechokwadi chekuti pane yekuona senitivity.
10. Kuwedzera: Izvi ndezvekuita yakanyura arc welding uye yakatwasuka seam simbi pombi kureba kwegomba dhayamita kuitira kuvandudza saizi yechubhu yesimbi nemazvo uye kunatsiridza kugovera kwekushushikana muchubhu yesimbi.
11. Hydraulic test: Izvi zvinoitwa pamushini we hydraulic test yesimbi mushure mekuwedzera ne-root test yekuona kuti pombi yesimbi inosangana nezvinodiwa nemuchina une otomatiki yekurekodha uye kuchengetedza.
12. Chamfering: Izvi zvinosanganisira kuongorora kunoitwa papombi yesimbi pakupera kwekuita kwese.
