Vim li cas LSAW yog qhov kev xaiv pib thaum pawg loj
Pile lub hauv paus tsuas yog xav tau cov yeeb nkab welded ib zaug qhov project txav dhau los ntawm seamless mills tuaj yeem tsim thiab dhau los ntawm qhov uas lub voj voog zeb tuaj yeem tuav ncaj nraim hauv kev tsav tsheb. Seamless tho sab saum toj tawm zoo nyob rau hauv 500mm OD nyob rau hauv feem ntau mills. SSAW yeeb nkab tuaj yeem ncav cuag loj diameters pheej yig, tab sis nws helical seam thiab coil -raws li feedstock ua hnyav -phab ntsa seem (25mm+) nyuaj rau tuav kom nruj roundness thiab straightness - ob qho tib si uas tseem ceeb tshaj rau piling dua rau ib tug zoo li qub pipeline, vim ib pawg yuav tsum ciaj sia rov rauj los yog vibratory tsis ua hauj lwm.
LSAW yeeb nkab yog dov los ntawm lub tiaj tiaj steel phaj, tsis yog coil, uas yog qhov ua rau nws xaiv qhov kev xaiv zoo ib zaug ib qhov project hu rau loj - txoj kab uas hla, hnyav - phab ntsa pawg yeeb nkab. Phaj tuab tsis txwv los ntawm coil- tsim kev txwv txoj kev SSAW yog, yog li LSAW mills niaj hnub muab 30-50mm phab ntsa hauv cov kab uas yuav nyuaj lossis tsis tsim nyog los tsim lwm txoj hauv kev. Qhov ncaj (tsis yog kauv) seam kuj yooj yim rau kev sib txuas ntawm thaj chaw - qhov kev txiav txim siab tiag tiag ntawm kev tsav- cov haujlwm pawg uas cov ntu tau welded ua ke ntawm qhov chaw raws li pawg nce mus rau hauv av.
Cov qauv thiab qib siv rau Piling LSAW Yeeb Nkab
Lub hauv paus piling tsis muaj ib tus qauv universal - qhov tseeb yog feem ntau nyob ntawm qhov project yog qhov twg thiab tus engineer sau qhov spec.
ASTM A252, ASTM A252yog tus qauv sau tshwj xeeb rau cov yeeb nkab pawg hauv Asmeskas kev lag luam, npog hom 1, 2, thiab 3 (Hom 3 muaj qhov siab tshaj plaws tensile lub zog thiab yog qib feem ntau teev rau LSAW- txoj kab uas hla piling). A252 teeb tsa qhov tsawg kawg nkaus tawm los thiab tensile yuav tsum tab sis tawm phab ntsa thickness xaiv rau tus tsim engineer raws li kev tsav tsheb kev nyuaj siab thiab axial load - nws tsis yog ib tug prescriptive dimensional qauv raws li ib tug structural raj spec.
API 5L(Qib B txog X70) tau teev tseg thaum ib qhov project xav tau kab- yeeb nkab- theem kev tswj tau zoo - tag nrho traceability, nruj chemistry txwv, yuav tsum tau NDT - txawm tias cov yeeb nkab mus rau hauv lub hauv paus es tsis yog ib tug pipeline. Qhov no yog ib txwm muaj nyob rau ntawm ntug dej hiav txwv thiab marine piling txoj hauj lwm uas tus neeg yuav khoom twb ua hauj lwm nrog API 5L ntawm lwm yam scopes.
TS EN 10219/ EN 10225npog welded structural hollow seem thiab offshore qauv, thiab tshwm sim nyob rau hauv European thiab Middle East infrastructure tej yaam num qhia piling los ntawm EN qib (S355, S460) es tsis yog ASTM.
Tsis muaj ib qho ntawm cov no hloov pauv tau ntawm daim ntawv - PO uas tsuas yog hais tias "A252 yeeb nkab, API 5L zoo" tab tom thov rau ob pob ntawv pov thawj sib txawv. Txiav txim siab tus txheej txheem twg tus engineer ntawm cov ntaub ntawv xav tau ua ntej muab qhov kev txiav txim, tsis yog tom qab zeb nug.
Technical Requirements Uas Tseem Ceeb rau Piling
Cov yeeb nkab uas yuav dhau mus zoo li kab yeeb nkab tseem tuaj yeem yog qhov kev xaiv tsis ncaj ncees rau pawg yog tias tsis tau kuaj xyuas:
Tsav kev ntxhov siab- cov yeeb nkab yuav tsum muaj sia nyob rov qab cuam tshuam los ntawm lub tshuab hluav taws xob lossis hydraulic rauj yam tsis muaj lub seam lossis lub hauv paus hlau yielding hauv zos. Qhov no yog vim li cas Charpy V- qhov ntsuas qhov cuam tshuam ntawm qhov ntsuas kub tsis tshua muaj feem ntau ntxiv rau piling POs txawm tias lub hauv paus tus qauv tsis nruj me ntsis kom nws - brittle fracture thaum tsav tsheb yog qhov tsis ua hauj lwm hom buyers tau txhawj xeeb txog.
Kev ncaj- bent yeeb nkab wanders tawm ntawm nws txoj kab npaj raws li nws tau tsav, uas tshwm sim tom qab raws li ib pawg uas tsis yog qhov chaw ntawm lub hauv paus kos duab hais tias nws yuav tsum yog. Kev ua siab ntev ntev (feem ntau Tsawg dua lossis sib npaug li 1.5mm ib meter ntawm qhov ntev) yuav tsum raug hu tawm ntawm PO, tsis xav.
Tawm ntawm - ntawm - roundness- tseem ceeb tshaj plaws uas cov khau khau lossis lub hau tsav tsheb yuav tsum tau zaum ntawm cov yeeb nkab kawg; ovality ntau dhau ua rau tsis zoo thauj khoom hloov ntawm qhov cuam tshuam.
Phab ntsa thickness pub rau corrosion- pawg feem ntau raug tso tawm ib feem (thaj chaw marine txaws, av nrog cov sulfate siab lossis chloride cov ntsiab lus) rau kev tsim lub neej ntawm cov qauv, yog li cov specs feem ntau ntxiv cov thickness pub dawb rau sab saum toj ntawm cov qauv kev suav, es tsis yog sizing phab ntsa rau structural load ib leeg.
Kev npaj kawg- square- txiav xaus rau thaj teb-welded splices, beveled xaus qhov twg siv cov txheej txheem vuam tshwj xeeb, lossis cov yeeb nkab haum nrog lub khau tsav tsheb / pawg taw tes rau kev nyuaj - tsav tsheb. Qhov no yuav tsum tau teev nyob rau hauv ib pawg txoj hauj lwm, txij li thaum splice xaus thiab ntiv taw xaus yog npaj sib txawv.
FAQ
Q: Puas yog LSAW yeeb nkab muaj zog dua SSAW yeeb nkab rau tib txoj kab uas hla thiab phab ntsa tuab?
A: Tsis yog los ntawm - ob leeg siv tag nrho -kev nkag mus rau hauv submerged arc vuam thiab tuaj yeem ua tau raws li qhov xav tau tib yam thiab tensile thaum ua rau tib qib. Qhov sib txawv ntawm qhov sib txawv yog tias LSAW tuav nruj dua qhov sib npaug thiab ncaj ntawm cov phab ntsa hnyav vim tias nws tau tsim los ntawm cov phaj tiaj tiaj es tsis yog coil, uas tseem ceeb tshaj rau cov pawg tsav tsheb dua li cov qauv zoo li qub.
Q: LSAW yeeb nkab puas tuaj yeem raug txiav thiab rov ua dua -welded ntawm qhov chaw kom ncav cuag qhov tob ntawm pawg?
A: Yog, qhov no yog cov qauv kev coj ua ntawm cov phiaj xwm sib sib zog nqus. Tus neeg yuav khoom cov txheej txheem vuam yuav tsum suav nrog cov yeeb nkab cov pa roj carbon sib npaug thiab cov phab ntsa tuab, thiab ob lub yeeb nkab kawg yuav tsum tau sib xyaw ua ke yuav tsum muaj qhov sib xyaw bevel npaj thaum lub sijhawm txiav txim.
Q: Puas yog LSAW yeeb nkab yuav tsum tau ntim nrog pob zeb?
A: Tsis yog ib txwm - nws nyob ntawm hom pawg. Qhib - cov yeeb nkab uas tau ua tiav lawm qee zaum sab laug tsis ua tiav (tso rau ntawm daim tawv nqaij sib txhuam thiab qhov kawg ntawm cov hlau thiab cov av ntsaws ib leeg), thaum lub qhov dhuav pawg casings thiab cov pawg sib xyaw feem ntau muaj cov pob zeb ntxiv tom qab kev teeb tsa. Qhov no yog kev txiav txim siab tsim qauv, tsis yog kev tsim khoom.
Q: Dab tsi yog qhov sib txawv ntawm cov khau tsav tsheb thiab qhov kawg txiav?
A: Ib lub khau tsav tsheb yog ib qho khoom siv hlau txuas ntxiv rau cov ntiv taw ntiv taw txhawm rau tiv thaiv cov yeeb nkab kawg thiab pab nkag los ntawm cov av ntom ntom, cobbles, lossis cov pob zeb huab cua. Plain txiav los yog beveled xaus yog siv nyob rau hauv cov av tej yam kev mob yog mos txaus uas cov liab qab yeeb nkab kawg yuav tsum tau tsav yam tsis muaj kev txhawb zog, los yog nyob rau sab saum toj kawg uas ib tug khau tsis xav tau txhua.
