Txheej txheem cej luam ntawm API 5L Qib A LSAW Yeeb Nkab
API 5L Qib A LSAW yeeb nkab yog tsim los ntawm kev tsim steel phaj rau hauv lub tog raj kheej thiab vuam qhov ntev seam los ntawm submerged arc txheej txheem, ua loj - kab kab yeeb nkab nrog cov ntaub ntawv weld zoo rau roj, roj thiab dej xa mus.
API 5L Qib A yog cov theem pib cov yeeb nkab qib, nrog qhov tsawg kawg nkaus lub zog ntawm 30 ksi (205 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 48 ksi (331 MPa). LSAW, los yog longitudinally submerged arc welded yeeb nkab, yog tsim los ntawm phaj: lub phaj npoo yog tsim los ntawm nias braking los yog JCOE sib sau, lub seam yog welded los ntawm sab hauv thiab sab nraud los ntawm submerged arc vuam, thiab cov weld feem ntau yog 100 feem pua ntawm ultrasonically los yog radiographically kuaj. Cov txheej txheem tso cai rau cov diameters loj heev thiab cov phab ntsa tuab uas seamless mills tsis tuaj yeem tsim.
Specification thiab Qib
Qib A muaj zog qis dua qib X- tab sis tseem siv qhov twg qhov kev tsim siab yog nruab nrab thiab kab tsis muaj kev ntxhov siab heev. Txoj kev tsim khoom ntawm LSAW muab ib qho ncaj, zoo ib yam weld nrog kev nkag mus rau tag nrho, thiab ob npaug -sided weld deposit muab kev qaug zog thiab siab zoo - tuav kev ua tau zoo. Vim tias qhov vuam yog tsim los ntawm cov txheej txheem mechanized nyob rau hauv kev tswj tsis tau, qhov zoo yog rov ua dua thoob plaws qhov kev tsim khoom.
Khoom Khoom
Cov khoom siv kho tshuab uas tseem ceeb rau cov khoom no yog txhais los ntawm kev tswj hwm kev qhia tshwj xeeb thiab qib: yam tsawg kawg nkaus lub zog, lub zog tensile, elongation thiab, qhov twg siv, hardness thiab cuam tshuam toughness. Cov txiaj ntsig no tau txheeb xyuas los ntawm kev sim ntawm txhua qhov cua sov thiab tshaj tawm ntawm daim ntawv pov thawj zeb kuaj, thiab tus neeg yuav khoom yuav tsum paub meej tias qhov kev lav phib xaub ua tau raws li cov qauv tsim ua ntej xaj.
Tej kev siv
Qib A LSAW yeeb nkab yog siv rau qis- cov kab xa tawm thiab xa tawm, cov kav dej thiab cov kav dej slurry, kev siv cov txheej txheem thiab piling, thiab cov haujlwm uas yuav tsum muaj cov kab loj loj txog 60 ntiv tes lossis ntau dua. Nws kuj yog ib qho kev xaiv zoo tshaj plaws rau onshore trunk kab uas cov qauv tsim tso cai rau qib qis zog.
Kev tsim khoom, kuaj thiab kev pov hwm zoo
LSAW yeeb nkab tau txheeb xyuas los ntawm kev tshuaj ntsuam xyuas thiab ntsuas tensile ntawm niam txiv cov hlau thiab cov vuam, cov kev ntsuas khoov ntawm cov vuam, kev ntsuas qhov cuam tshuam qhov xav tau, thiab 100 feem pua ntawm ultrasonic lossis radiographic kuaj ntawm longitudinal weld. Ib qho kev sim hydrostatic yog siv rau cov yeeb nkab tiav, thiab daim ntawv pov thawj zeb xeem cov ntaub ntawv cov cua sov, chemistry, mechanical zog thiab cov txiaj ntsig kev xeem.
Kev Xaiv thiab Kev Txiav Txim Kev Qhia
Thaum xaj API 5L Qib A LSAW Yeeb Nkab, cov txheej txheem tswj hwm, qib lossis cov khoom tsim, sab nraud txoj kab uas hla, phab ntsa thickness, ntev, qhov kawg tiav thiab cov kev xeem ntxiv lossis ntawv pov thawj yuav tsum tau teev nyob rau hauv daim ntawv xaj yuav khoom. Nug tus neeg muag khoom kom paub meej tias muaj, kev kho cua sov thiab cov ntaub ntawv xa tuaj ua ntej kev tsim khoom, thiab thov daim ntawv pov thawj zeb kuaj kom cov tshuaj tshuaj ntsuam xyuas, cov txiaj ntsig kev ntsuas tshuab thiab traceability tuaj yeem kuaj xyuas qhov kev txiav txim.
FAQ
Q1. LSAW sawv rau dab tsi?
Longitudinally submerged arc vuam. Lub longitudinal seam ntawm cov yeeb nkab yog welded los ntawm submerged arc txheej txheem, feem ntau los ntawm ob sab hauv thiab sab nraud.
Q2. API 5L Qib A yog dab tsi?
Yam tsawg kawg nkaus lub zog ntawm 30 ksi (205 MPa) thiab lub zog tensile yam tsawg kawg nkaus ntawm 48 ksi (331 MPa). Nws yog qhov qis tshaj lub zog kab yeeb nkab qib hauv API 5L.
Q3. Vim li cas thiaj xaiv LSAW es tsis txhob seamless lossis ERW?
LSAW raug xaiv rau cov kab uas loj heev thiab cov phab ntsa tuab uas seamless mills tsis tuaj yeem tsim thiab ERW mills raug txwv rau. Lub submerged arc weld tau soj ntsuam tag nrho, ua rau lub seam txhim khu kev qha.
Q4. Puas yog lub vuam raug tshuaj xyuas?
Yog lawm. Nyob rau hauv niaj hnub xyaum, longitudinal weld ntawm LSAW yeeb nkab yog 100 feem pua kuaj xyuas los ntawm ultrasonic los yog radiographic kuaj, thiab cov yeeb nkab yog hydrostatically kuaj tom qab vuam.
Q5. LSAW npog qhov luaj li cas?
LSAW yeeb nkab feem ntau pib qhov twg ERW nres, feem ntau yog li ntawm 16 txog 60 ntiv tes sab nraud, nrog phab ntsa tuab txog li 1 nti lossis ntau dua nyob ntawm lub zeb.
