Peb cov Large Diameter Straight Seam Welded Pipe tau tsim los kom tau raws li cov qauv nruj uas cov neeg yuav khoom loj xav tau - tshwj xeeb yog API 5L (rau roj thiab roj) thiab EN 10219 (rau kev siv qauv). Cov qauv no tsis yog cov ntaub ntawv xwb; lawv yog vim li cas koj cov neeg yuav khoom thiaj li ntseeg tau cov yeeb hlau rau cov haujlwm tseem ceeb xws li cov kav dej ntev lossis cov qauv offshore platform.
Peb siv cov hlau high-strength low-alloy (HSLA), nrog lub zog yield tsawg kawg 355 MPa thiab lub zog tensile 490-630 MPa. Vim li cas qhov ntawd tseem ceeb? Nws txhais tau tias cov yeeb hlau tuaj yeem tiv tau lub siab siab - peb sim ib lub yeeb hlau 12mm tuab los ntawm kev ua kom nws tiv tau 8 MPa ntawm lub siab sab hauv rau 24 teev, thiab nws qhia tias tsis muaj kev hloov pauv. Rau cov neeg yuav khoom loj, qhov kev ntseeg siab no txo cov nqi uas yuav tsum tau kho hauv qhov chaw.
Txhua lub yeeb hlau muaj txoj kab ncaws los ntawm 529mm txog 2020mm (peb tuaj yeem kho kom txog 3000mm) thiab cov ntev xaiv los ntawm 3m txog 18m. Lub straight seam yog vuam siv ob sab submerged arc welding (SAW), uas tsim lub zog vuam 90% ntawm cov hlau ntsws - peb xyuas qhov no nrog X-ray thiab ultrasonic testing ntawm txhua qhov vuam, kom tsis muaj kab nkaum. Peb kuj muab 3PE anti-corrosion coating (peel strength ≥ 70 N/cm) uas peb sim hauv salt spray rau 4000 teev nrog tsis muaj xeb. Txawm tias koj cov neeg yuav khoom xav tau nws rau kev thauj hluav taws xob lossis kev tsim kho, peb cov Large Diameter Straight Seam Welded Pipe muab qhov sib xws uas lawv xav tau los yeej cov haujlwm.
peb siv lub tshuab khoov hlau CNC los ua cov ntawv hlau kom zoo li lub cylinder (nrog qhov tolerance circumference ±1mm). Lub tshuab siv 16 lub hydraulic rollers kom cov yeeb hlau ncaj nraim - tsis muaj kev khoov, uas yog qhov tseem ceeb rau cov kav dej ntev. Tom qab ntawd, peb kho lub straight seam nrog tack welding ua ntej tsiv mus rau ob sab SAW: thawj qhov vuam ua los ntawm sab hauv, tom qab ntawd lub yeeb hlau tig rau sab nraud, nrog kub tswj ntawm 280-320°C kom tsis txhob brittleness.
Tom qab vuam, peb ua heat-treat cov yeeb hlau hauv lub tshuab kub 920°C (tuav rau 1 teev, ces txias ntawm 5°C ib feeb) kom txo tau kev ntxhov siab sab hauv. Peb mam li txiav cov yeeb hlau rau qhov ntev nrog lub tshuab plasma (accuracy ±2mm) thiab ua kev sim hydrostatic - muab dej puv txhua lub yeeb hlau thiab ua siab rau 1.5 npaug ntawm lub siab ua haujlwm rau 10 feeb. Yog tias nws tawg, peb muab pov tseg. Thaum kawg, peb them thiab ntim txhua lub Large Diameter Straight Seam Welded Pipe nrog foam sleeve thiab steel cradle, kom nws tuaj txog yam tsis muaj khawb.
Tam sim no, peb muaj 3 kab ntau lawm tshwj xeeb rau Large Diameter Straight Seam Welded Pipe, txhua kab tsim tau 20-30 lub yeeb hlau ib hnub (raws li txoj kab ncaws). Qhov ntawd ntxiv rau lub peev xwm txhua hli li 2400-3600 meters, lossis 1400-2100 tons.
Peb khaws 5000 tons ntawm cov ntawv hlau hauv peb lub tshuab, yog li peb yeej tsis tos cov khoom raw. Peb kuj muaj pab neeg logistics tshwj xeeb uas ua haujlwm nrog cov tuam txhab shipping uas tshwj xeeb rau cov khoom loj - peb tuaj yeem npaj flat-rack container shipping lossis bulk transport mus rau Europe thiab America, thiab peb tuav tag nrho cov ntaub ntawv xa tawm (xws li CE certificates thiab material test reports) kom tsis txhob ncua kev tshem tawm.
Nyob rau 3 xyoo dhau los, peb tuav 99.1% kev xa khoom raws sijhawm. Peb kuj muab kev txhawb nqa rau cov kev txiav txim ceev - yog tias koj cov neeg yuav khoom xav tau cov yeeb hlau hauv 1 lub lis piam, tsuas yog qhia peb, thiab peb yuav hloov cov peev txheej ntau lawm. Tsis muaj kev txiav txim loj dhau lossis ceev dhau ntawm no - peb kho txhua qhov kev thov loj raws li qhov tseem ceeb.
Peb tsis yog muag Large Diameter Straight Seam Welded Pipe nkaus xwb - peb xav tsim kev sib koom tes mus ntev nrog peb cov neeg yuav khoom loj, yog li peb cog lus uas peb tuaj yeem ua tau. Ua ntej, 12 xyoo kev lav ntawm cov anti-corrosion coating thiab 5 xyoo kev lav rau lub yeeb hlau nws tus kheej: Qhov no ua raws li EU cov cai tiv thaiv cov neeg siv khoom, yog li koj cov neeg yuav khoom xav tias nyab xeeb.
Qhov thib ob, kev qhia tag nrho txog qhov zoo: txhua pawg tuaj nrog ib daim ntawv qhia kuaj ntxaws, nrog rau cov ntaub ntawv vuam zog, cov txiaj ntsig kev sim siab, thiab coating tuab ntsuas - kos npe los ntawm peb pab neeg zoo uas tau ntawv pov thawj ISO 9001.
Qhov thib peb, cov lus ceev yooj yim rau cov neeg yuav khoom loj: peb muab 25% ua ntej, 75% nyiaj tshuav tom qab xa khoom (L/C, T/T, lossis open account rau)
