API 5L Pipe Standard Scope
Nyob rau hauv API SPEC 5L 46th Edition, tus qauv Scope yog txhais raws li: "Yuav tsum tau rau kev tsim khoom ntawm ob yam khoom specification theem (PSL1 thiab PSL2) seamless thiab welded steel kav rau siv nyob rau hauv pipeline tsheb thauj mus los systems nyob rau hauv cov roj av thiab natural gas industries. Cov qauv no tsis siv rau cam khwb cia yeeb nkab."
Txhawm rau kom ua tiav, API 5L yeeb nkab yog cov pa roj carbon steel yeeb nkab siv rau cov roj thiab cov pa xa hluav taws xob. Lub caij no, lwm cov kua dej xws li chav dej, dej, thiab slurry kuj tuaj yeem siv API 5L tus qauv rau lawv cov hom phiaj sib kis.
Ntau hom kev tsim khoom
API 5L specification npog cov kev tsim khoom hauv welded thiab seamless.
Welded Hom: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe
API 5L welded yeeb nkab ntau hom yog raws li nram no:
ERW
Hluav taws xob Resistance Welded, rau cov yeeb nkab txoj kab uas hla ib txwm nyob rau hauv 24 ntiv tes.
01
DSAW/SAW
Ob chav Submerged Arc Vuam / Submerged Arc Vuam, hloov vuam txoj kev ntawm ERW rau cov kav dej loj dua.
02
LSAW
Longitudinal SAW, rau txoj kab uas hla mus txog 48 ntiv tes. Kuj hu ua JCOE manufacturing process.
03
SSAW/HSAW
Kauv Submerged Arc Welded / Helical SAW, yeeb nkab diameters txog 100 ntiv tes.
04
Xyuas ntawm no rau qhov sib txawv ntawm ERW, LSAW, thiab SSAW kav.
Seamless Hom: Kub Rolled Seamless thiab Cold Rolled Seamless Yeeb Nkab
Seamless manufacturing hom feem ntau yog rau cov kav dej me me (feem ntau hauv qab 24 ntiv tes).
(Thaum txoj kab uas hla ntawm cov yeeb nkab yog tsawg dua 150 hli lossis 6 ntiv tes, cov yeeb nkab steel seamless feem ntau siv dua li cov yeeb nkab steel welded.)
Kuj tseem muaj cov kav dej seamless ntawm cov kab loj loj. Los ntawm kev siv cov txheej txheem kub dov, peb tuaj yeem tau txais cov kav dej seamless nrog txoj kab uas hla mus txog yuav luag 20 ntiv tes (508 hli). Yog tias koj xav tau cov kav dej seamless nrog txoj kab uas hla tshaj 20 ntiv tes, peb tuaj yeem ua rau lawv los ntawm cov txheej txheem nthuav dav kub, nrog qhov siab tshaj plaws mus txog 40 ntiv tes (1016 hli).
API 5L Pipe Manufacturing Development
Nyob rau hauv lub xyoo ntxov tshaj plaws, ntxiv rau Seamless thiab ERW, SAW manufacturing technologies, API 5L steel yeeb nkab kuj yuav raug tsim nyob rau hauv lub cub tawg lap-welded (luag hauv API 5L hauv 1962).
Nrog rau txoj kev loj hlob ntawm pipeline steel phaj- ua tshuab, yeeb nkab txoj kev thiab vuam tshuab kuj tau pom kev txhim kho tseem ceeb, yog li ntau cov kav dej ERW thiab SAW kav tau siv rau hauv kev tsim cov kav dej. Thaum nws los txog rau loj - txoj kab uas hla steel kav, SAW yeeb nkab tau txais txiaj ntsig zoo. Nrog cov khoom siv tsawg dua thiab cov txheej txheem tsim khoom yooj yim thiab tsis sib xws, welded steel yeeb nkab tau ua thawj qhov chaw hauv cov roj thiab roj kab yeeb nkab industries.
API 5L npog Qib B, X42, X46, X52, X56, X60, X65, X70, X80
API 5L steel kab yeeb nkab txais cov qib steel sib txawv, uas yog Gr. B, X42, X46, X52, X56, X60, X65, X70, X80. Qee lub tuam txhab muaj peev xwm tsim cov qib steel mus txog X100 thiab X120. Raws li steel kab kav 'qib qib siab dua, lawv muaj kev tswj hwm nruj dua ntawm kev tswj hwm cov pa roj carbon sib npaug thiab kev ua haujlwm zoo dua qub.
Ntxiv mus, nyob rau hauv tib qib, seamless thiab welded API 5L kav dej muaj cov tshuaj sib txawv, uas yog, welded kav yuav tsum nruj dua thiab qis dua cov pa roj carbon thiab sulfur.
Hais txog kev xa khoom sib txawv, kuj tseem muaj raws li - dov, normalizing dov, thermomechanical dov, normalizing tsim, normalized, normalized thiab tempered, quenched thiab tempered.

API 5L Line Pipe Test Methods
Hydrostatic Test
Jointers yuav tsum tsis txhob yog hydrostatically theem, yog hais tias cov feem ntawm cov yeeb nkab siv nyob rau hauv ua cov jointers tau ua tiav hydrostatically kuaj ua ntej kev koom ua ke.
Tsuas yog nyob rau hauv qhov xwm txheej dhau los, cov yeeb nkab yuav tsum tiv thaiv qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov vuam seam lossis cov yeeb nkab lub cev.
Khoov xeem
Kev tawg yuav tsum tsis txhob tshwm sim hauv ib feem ntawm cov qauv thiab qhib qhov vuam yuav tsum tsis txhob tshwm sim thiab.
Thov nco ntsoov: Rau txhua qhov kev ntsuas khoov, qhov vuam txuas mus rau 6.4 hli (0.25 nyob rau hauv) ntawm txhua sab ntawm fusion kab.
Flattening Test
Txoj kev ntsuas flattening yog siv los txheeb xyuas qhov kev ua haujlwm deformation ntawm kab yeeb nkab rau qhov loj me thiab tso saib nws qhov tsis xws luag. Raws li kev ntxhov siab thiab deformation yam ntxwv ntawm cov qauv thaum lub sij hawm flattening txheej txheem, lub flattening xeem yuav tsum tau qhia cov kev tiv thaiv rau longitudinal cracking thiab circumferential cracking ntawm cov yeeb nkab thiab tso saib nws sab hauv thiab defects.
Dua li ntawm peb qhov kev ntsuam xyuas saum toj no, muaj lwm yam kev sim uas yuav tsum tau ua hauv txhua qhov xwm txheej.

Cov yeeb nkab kawg suav nrog qhov ntev ntawm 4 hauv noj txhua qhov ntawm cov yeeb nkab extremities Rau SMLS yeeb nkab kev kam rau siab thov rau t Tsawg dua los yog sib npaug rau 0.984in thiab qhov kam rau ua rau cov yeeb nkab tuab yuav tsum yog raws li kev pom zoo Rau cov yeeb nkab txuas nrog D Ntau dua lossis sib npaug ntawm 8.625in thiab rau cov yeeb nkab uas tsis yog - nthuav dav, txoj kab uas hla kev kam rau siab thiab qhov tawm - ntawm - roundness kam rau ua yuav raug txiav txim siab siv qhov ntsuas hauv txoj kab uas hla lossis ntsuas hauv txoj kab uas hla es tsis yog OD teev. Rau kev txiav txim siab ua raws li txoj kab uas hla txoj kab uas hla, cov yeeb nkab txoj kab uas hla yog txhais raws li lub voj voog ntawm cov yeeb nkab nyob rau hauv ib lub dav hlau circumferential faib los ntawm Pi. |

Yog hais tias qhov kev txiav txim yuav tsum tau qhia ib tug minus kam rau ua rau phab ntsa thickness tsawg tshaj li qhov muaj nqis muab rau hauv lub rooj no, qhov ntxiv kam rau ua rau phab ntsa thickness yuav tsum tau nce los ntawm ib tug npaum li cas txaus kom muaj feem xyuam rau ntau yam kam rau ua. Rau cov yeeb nkab nrog D Ntau dua lossis sib npaug ntawm 14.000 hauv thiab t Ntau dua lossis sib npaug ntawm 0.984in, phab ntsa thickness kam rau ua hauv zos tuaj yeem tshaj qhov ntxiv rau cov phab ntsa tuab los ntawm ib qho ntxiv 0.05t muab qhov ntxiv rau qhov siab rau huab hwm coj tsis tshaj. Qhov ntxiv kam rau ua rau phab ntsa thickens tsis siv rau qhov chaw weld Saib tag nrho API5L spec kom paub meej |
