S275 Welded JCOE LSAW Carbon Steel Pipe

Taw qhia rau S275 JCOE Tsim LSAW Welded Carbon Steel Pipe

Cov txiaj ntsig tseem ceeb ntawm S275 JCOE LSAW carbon steel yeeb nkab nyob hauv kev sib xyaw ua ke zoo tshaj plaws ntawm cov ntaub ntawv, txheej txheem, thiab kev ua haujlwm:

1. Kev ua haujlwm zoo heev - Siv JCOE cov txheej txheem txias txias sib xyaw ua ke nrog cov khoom siv txoj kab uas hla nthuav tawm tau zoo tshem tawm cov kev ntxhov siab, kom ntseeg tau tias tsis tshua muaj siab roundness thiab qhov tseeb ntawm cov yeeb nkab;

2. Cov khoom siv qis heev -kub toughness - S275J0 / J2 qib cov khoom ua kom muaj kev cuam tshuam zoo rau qhov chaw ib puag ncig xws li 0℃txog -20 degree, haum rau cov haujlwm hauv cheeb tsam txias heev;

3. Txhim khu kev ntseeg tau zoo - Submerged arc vuam tshuab ua cov ntaub ntawv sib sib zog nqus welds, nrog rau lub zog thiab toughness ntsuas txog li 95% ntawm cov khoom siv hauv paus;

4. Lub zog muaj zog tiv thaiv - Cov txheej txheem ua tiav ua kom lub raj xa dej tuaj yeem tiv taus siab - kev thauj mus los siab, ua rau nws tsim nyog tshwj xeeb rau cov txheej txheem tseem ceeb xws li cov roj thiab cov kav dej;

5. Cov txheej txheem kev hloov pauv tau zoo - Loj - cov kav dej tshwj xeeb nrog cov kab uas hla ntau tshaj 1620mm thiab phab ntsa thicknesses tshaj 40mm tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam haujlwm loj.

S275 JCOE Kev Tsim Cov Txheej Txheem:

S275 JCOE tsim cov txheej txheem tsim khoom yog cov cuab yeej siv siab tshaj plaws rau kev tsim cov loj - txoj kab uas hla, tuab -walled ncaj seam submerged arc welded kav (LSAW). Nws cov txheej txheem tuaj yeem muab faib ua cov kauj ruam tseem ceeb hauv qab no:

1. Raw Material Preparation: Tom qab kuaj ultrasonic, S275 qib steel daim hlau yog milled raws li cov qauv tsim los tsim cov slab nrog cov dav dav thiab du bevel.

2. Pre- khoov ntug khoov: Lub tshuab ua ntej- khoov yog siv los khoov cov npoo ntawm cov phaj steel ntawm ob sab, ua ib qho arc zoo ib yam nrog cov yeeb nkab kawg ntawm lub cev curvature, tiv thaiv cov npoo ncaj los yog wrinkles los ntawm kev tsim cov txheej txheem tom ntej.

3. J-C-O Tsim:

- J-forming: Ib qho xovxwm loj yog siv los rov nias rau ntawm qhov chaw ntawm lub pre- bent steel phaj, ua rau ob sab mus rau ib txwm nkhaus upwards, tsim ib tug tshwj xeeb "J" zoo li tus ntoo khaub lig-section.

- C-forming: Kev siv zog txuas ntxiv mus, txuas ntxiv khoov tus "J" zoo li tus ntoo khaub lig-section mus rau qhov kaw "C" ntau dua.

- O-shaping: Lub kaw pwm yog siv los nias lub "C" - zoo li tus hlau phaj rau hauv lub cylindrical "O" - zoo li cov yeeb nkab.

4. Sab hauv thiab Sab Nrauv Vuam: Ntawm qhov ncaj seam tsim los ntawm kev kaw ntawm cov yeeb nkab tsis muaj, submerged arc vuam yog thawj zaug siv rau sab hauv phab ntsa vuam, ua raws li los ntawm flipping lub yeeb nkab lub cev rau txheej phab ntsa vuam, kom ntseeg tau tias tag nrho cov nkag thiab zoo ib yam ntawm cov weld.

5. Mechanical Expansion: Ib segmented expansion taub hau yog siv rau radially nthuav lub welded yeeb nkab lub cev. Cov kauj ruam tseem ceeb no tuaj yeem:

- Tshem tawm cov kev ntxhov siab uas tshwm sim thaum tsim thiab vuam

- Precisely kho lub roundness thiab straightness ntawm cov yeeb nkab steel

- Tshawb xyuas qhov ductility thiab tag nrho qhov sib xws ntawm cov vuam

6. Kev Ua tiav thiab Kev Tshuaj Xyuas: Tom qab chamfering, kev sim hydrostatic, tsis yog - kuaj kev puas tsuaj, thiab kev tshuaj xyuas qhov ntev, cov yeeb nkab steel tiav raws li cov qauv yuav tsum tau ua thaum kawg.

Cov txheej txheem no, dhau los ntawm kev sib xyaw ua ke zoo tshaj plaws ntawm cov kauj ruam-los ntawm- kauj ruam tsim thiab kev nthuav dav, ua kom qhov tseeb qhov tseeb thiab cov khoom siv kho tshuab ntawm S275 steel kav hauv siab-kawg daim ntawv thov xws li cov kav xa hluav taws xob thiab cov qauv loj.

Hais txog peb

GNEE STEEL yog lub tuam txhab ua lag luam thoob ntiaj teb tshwj xeeb hauv siab -kawg welded steel kav. Nws cov khoom tseem ceeb yog tus qauv ncaj seam submerged arc welded kav, muab cov kev daws teeb meem thiab cov kav dej kho kom haum rau lub ntiaj teb lub zog thiab cua zog ua haujlwm.
