Spiral Submerged-Arc Welded Steel Pipe

 

Kauv submerged arc welded steel yeeb nkab yog tsim los ntawm kub dov steel sawb raws li cov yeeb nkab billet, tsim nyob rau hauv ib tug kauv zoo nyob rau hauv chav tsev kub. Lub kauv seam yog welded siv txoj kev tsis siv neeg submerged arc vuam txoj kev, ua rau cov yeeb nkab hlau nrog ob qho tib si sab hauv thiab sab nraud submerged arc weld seam. Nws feem ntau yog siv rau kev thauj mus los ntawm cov dej, cov qauv hlau, thiab cov hauv paus hauv paus.

Cov txheej txheem tsim khoom ntawm Kauv Submerged Arc Welded Hlau Yeeb Nkab

1. Raw Materials Inspection: Cov khoom siv raw, suav nrog steel coil, vuam hlau, thiab flux, raug nruj nruj ntawm lub cev thiab tshuaj xyuas ua ntej siv.

2. Xaus Vuam ntawm Hlau Sawb: Qhov kawg ntawm cov hlau sawb yog pob tw-welded siv ib los yog ob lub xaim submerged arc vuam. Tom qab tsim rau hauv cov kav dej, tsis siv neeg submerged arc vuam yog siv los kho vuam.

3. Pre-Forming Preparation: Ua ntej tsim, steel sawb undergoes straightening, ntug trimming, ntug planing, deg tu, thiab pre-bending ntug kho.

4. Kev Tswj Siab Thaum Lub Sijhawm Thauj: Hluav taws xob tiv tauj lub ntsuas hluav taws xob tswj lub siab ntawm cov roj thooj voos kheej kheej ntawm ob sab ntawm lub conveyor, kom ntseeg tau tias kev thauj mus los ntawm cov hlau zoo.

5. Forming: Sab nraud lossis sab hauv tswj cov menyuam shaping yog ua haujlwm.

6. Weld Gap Control: Weld gap control devices kom ntseeg tau tias qhov sib txawv ntawm cov welds ua tau raws li qhov yuav tsum tau ua ntawm vuam, nrog kev tswj nruj ntawm cov yeeb nkab txoj kab uas hla, kev sib tsoo, thiab vuam qhov sib txawv.

7. Submerged Arc Vuam: Ob sab hauv thiab sab nraud vuam siv American Lincoln vuam tshuab rau ib leeg lossis ob lub xaim submerged arc vuam, kom ruaj khov vuam zoo.

8. Kev Ntsuas Ultrasonic: Weld seams raug tshuaj xyuas siv online txuas ntxiv ultrasonic tsis siv neeg qhov tsis pom kev tsis zoo, kom ntseeg tau 100% kev pab cuam ntawm kev kuaj tsis muaj kev puas tsuaj ntawm kauv weld seams. Txhua qhov tsis xws luag ua rau lub tswb tsis siv neeg thiab cim, tso cai rau cov neeg ua haujlwm tsim kho kom kho cov txheej txheem tam sim thiab tshem tawm qhov tsis xws luag.

9. Txiav: Cua plasma txiav tshuab txiav cov kav dej rau hauv tus kheej ntev.

10. Kev tshuaj xyuas thawj zaug: Tom qab txiav, txhua lub batch ntawm cov kav dej tau raug tshuaj xyuas thawj zaug, tshuaj xyuas cov khoom siv ntawm cov khoom siv vuam, tshuaj lom neeg muaj pes tsawg leeg, fusion txheej txheem, qhov zoo ntawm qhov chaw, thiab tsis muaj kev puas tsuaj, xyuas kom ua raws li cov qauv tsim ua ntej kev tsim khoom.

11. Kev kho qhov tsis xws luag: Cov chaw cim rau ntawm qhov vuam seams undergo phau ntawv ultrasonic thiab X-ray rov kuaj xyuas. Yog tias qhov teeb meem raug lees paub, lawv raug kho thiab raug kuaj xyuas tsis muaj kev puas tsuaj dua kom txog thaum tshem tawm cov teeb meem.

12. X-ray Examination: steel strips, weld seams, thiab sib tshuam T-joints nrog kauv weld seams undergo X-ray muaj peev xwm los yog radiographic tshuaj xyuas.

13. Hydrostatic Testing: Txhua cov yeeb nkab tau dhau los ntawm kev ntsuas hydrostatic siab siv radial sealing. Kev ntsuas siab thiab lub sijhawm yog tswj hwm nruj los ntawm cov yeeb nkab hydraulic microcomputer kuaj cov cuab yeej, nrog cov ntsuas ntsuas tau txiav luam tawm thiab kaw.

14. End Mechanical Processing: Lub ntsej muag kawg yog machined los xyuas kom meej perpendicularity, bevel kaum sab xis, thiab fillet tswj qhov tseeb.
