LSAW (Longitudinal ob submerge arc vuam)carbon steel yeeb nkabyog homSAW cevua los ntawm cov hlau phaj uas tau kub dov los ntawm JCOE lossis UOE txoj kev siv tshuab.JCOE thev naus laus zis sawv cev rau cov txheej txheem tsim thiab tsim cov txheej txheem koom nrog thaum tsim khoom nrog rau cov vuam sab hauv thiab sab nrauv thiab kev nthuav dav txias ua tom qab vuam.
Thaum piv rau UOELSAW steel kav, LSAW yeeb nkab manufacturers hauv Suav teb tuaj yeem tsim ntau qhov ntau thiab tsawg li: OD 406 mm - 1620 mm, thickness 6.35 mm - 60 mm, yeeb nkab ntev 2 m - 18 m nrog rauLSAW tubmuaj superiority.
- LSAW steel yeeb nkab raug txheej txheem
The LSAWloj txoj kab uas hla steel yeeb nkabmanufacturing txheej txheem yog piav nyob rau hauv cov kauj ruam hauv qab no:
1. Plate Probe: Qhov no yog siv rau kev tsim cov kab loj loj LSAW pob qij txha txoj cai tom qab nws nkag mus rau hauv cov kab ntau lawm uas yog thawj zaug puv-board kuaj ultrasonic.
2. Milling: Lub tshuab siv rau milling ua qhov haujlwm no los ntawm ob-edged milling phaj kom ua tau raws li qhov yuav tsum tau ua ntawm lub phaj dav thiab ob sab sib npaug rau cov duab thiab qib.
3. Pre-curved sab: Sab no yog ua tiav los ntawm kev siv lub tshuab ua ntej khoov ntawm lub phaj pre-bending ntug.Lub phaj ntug yuav tsum tau raws li qhov yuav tsum tau curvature.
4. Kev sib sau: Tom qab cov kauj ruam ua ntej khoov, hauv thawj ib nrab ntawm JCO molding tshuab, tom qab stamped steel, nws yog nias rau hauv "J" zoo li thaum nyob rau lwm ib nrab ntawm tib steel phaj nws yog khoov thiab nias. mus rau hauv "C" zoo, ces qhov kawg qhib daim ntawv "O" zoo.
5. Pre-welding: Qhov no yog ua kom lub welded yeeb nkab steel ib tug ncaj seam tom qab nws tau tsim thiab ces siv roj welding seam (MAG) rau nruam vuam.
6. Sab hauv weld: Qhov no yog ua tiav nrog ib tug tandem multi-wire submerged arc vuam (txog plaub hlau) nyob rau sab hauv ntawm lub ncaj seam welded steel yeeb nkab.
7. Sab nraud Weld: Sab nraud weld yog tandem multi-wire submerged arc vuam nyob rau sab nraud ntawm LSAW steel yeeb nkab vuam.
8. Kev Ntsuas Ultrasonic: Sab nraud thiab sab hauv ntawm txoj hlua ncaj nraim welded steel yeeb nkab thiab ob sab ntawm cov khoom siv hauv paus yog welded nrog 100% tshuaj xyuas.
9. X-ray tshuaj xyuas: X-ray muaj TV tshuaj xyuas yog ua los ntawm sab hauv thiab sab nraud uas siv cov duab ua kom paub tseeb tias muaj kev tshawb pom rhiab heev.
10. Kev nthuav dav: Qhov no yog rau kev ua tiav submerged arc vuam thiab ncaj seam steel yeeb nkab ntev lub qhov taub kom txhim kho cov hlau raj qhov loj precision thiab txhim kho qhov kev faib tawm ntawm kev ntxhov siab hauv cov raj steel.
11. Hydraulic xeem: Qhov no yog ua los ntawm hydraulic xeem tshuab rau steel tom qab nthuav tawm los ntawm cov hauv paus kev sim kom ntseeg tau tias cov yeeb nkab steel ua tau raws li tus qauv yuav tsum tau ua nrog lub tshuab muaj cov ntaub ntawv tsis siv neeg thiab khaws cia.
12. Chamfering: Qhov no suav nrog kev tshuaj xyuas ntawm cov yeeb nkab steel thaum kawg ntawm tag nrho cov txheej txheem.
