Longitudinally Submerged Arc Vuam (LSAW) Welded Steel Pipe

Lus piav qhia luv luv:

LSAW yeeb nkab yog Longitudinal Submerged Arc Vuam yeeb nkab.

Kev tsim cov thev naus laus zis ntawm LSAW yeeb nkab yog hloov tau, thiab nws tuaj yeem tsim cov kev qhia tshwj xeeb thiab cov qauv uas tsis tuaj yeem tsim los ntawm cov yeeb nkab steel ntau zaus, kauv steel yeeb nkab thiab txawm tias seamless steel yeeb nkab.

Yuav Siv Li Cas LSAW Welded Steel Pipelines

Cov hlau yooj yim thiab vuam hlau tau raug kuaj raws li qhov tshwj xeeb ntawm cov yeeb nkab API SPEC 5L, DIN, EN, ASTM, GOST tus qauv thiab lwm yam qauv.

Tsis tas li, LSAW yeeb nkab tuaj yeem txuas nrog flanges, nqa lub qhov muag thiab lwm yam nyob ntawm cov neeg siv khoom xav tau.

LSAW yeeb nkab yog siv rau kev xa cov kua dej xws li roj, roj thiab kev thauj mus los hauv dej thiab siv rau cov dej hiav txwv thiab kev tsim kho hauv av.Cov khoom no yog tsim nyob rau hauv Suav teb thiab raug xa tawm mus rau lwm lub tebchaws xws li Tebchaws Meskas, Canada, Is Nrias teb, Pakistan, Africa, thiab lwm yam.

LSAW Steel Pipe Manufacturing Txheej txheem

Lub LSAW loj txoj kab uas hla steel yeeb nkab manufacturing 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 thiaj li txhawm rau txhim kho lub raj steel 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.
