Dab tsi yog Qhov Zoo ntawm GNEE API 5L Pipeline Rau Roj Thiab Roj?

Siab zog -rau- Qhov hnyav piv (X- Qib)

API 5L npog ntau qib ntawm qib B txog X100. Siab - qib zog zoo liX65 thiab X70tso cai rau engineers los tsim cov kav dej nrogthinner phab ntsa thicknessesthaum tswj kev ntsuas siab sab hauv.

Qhov txiaj ntsig:Qhov no txo qis tag nrho cov tonnage ntawm cov hlau uas xav tau rau ntev - cov kav dej nyob deb, ua rau txo cov nqi khoom thiab txo nqi tsheb thauj mus los / tuav.

Txhim kho Fracture Toughness (PSL2 Ua raws)

Tsis zoo li cov qauv hlau yooj yim, API 5LPSL2 (Product Specification Level 2)cov kav dej yuav tsum tau uaCharpy V-Kev ntsuas qhov cuam tshuam (CVN).

Qhov txiaj ntsig:Qhov no ua kom cov khoom nyob twj ywm thiab tuaj yeem nqus tau lub zog ntawm qhov kub thiab txias, tiv thaiv "nkim tawg" lossis kev puas tsuaj tawg tawg. Qhov no yog ib qho tseem ceeb rau cov kav dej uas khiav los ntawm huab cua txias los yog subsea ib puag ncig uas qhov kev pheej hmoo ntawm kev tawg yog qhov kev txhawj xeeb loj txog kev nyab xeeb.

Kev Tiv Thaiv Tshwj Xeeb rau "Sour Service" (H2S Ib puag ncig)

Hauv kev rho tawm roj thiab roj, "qaub" ib puag ncig muaj cov qib siab ntawm Hydrogen Sulfide (H2S). API 5L kav dej tuaj yeem tsim ua raws liNACE MR0175/ISO 15156qauv.

Qhov txiaj ntsig:Cov kav dej no raug kho kom tiv tausHydrogen{0}}Induced Cracking (HIC)thiabSulfide Stress Cracking (SSC). Qhov tshwj xeeb metallurgy no tiv thaiv kev txhim kho hauv kev ua tsis tiav uas yuav ua rau muaj kev cuam tshuam thiab kev puas tsuaj ib puag ncig hauv cov roj av qaub.

Superior Field Weldability (Controlled Carbon sib npaug)

Cov tshuaj muaj pes tsawg leeg ntawm API 5L yeeb nkab yog nruj me ntsis tswj, tshwj xeeb tshaj yog covCarbon Equivalent (CEV)tus nqi.

Qhov txiaj ntsig:Lub CEV qis dua ua kom zoo tshaj plaws weldability thaum lub sijhawm teeb tsa. Qhov no yuav txo tau qhov kev xav tau ntawm kev kho cua sov ua ntej thiab txo qhov kev pheej hmoo ntawm cov kab mob khaub thuas tawg hauv Heat Affected Zone (HAZ), tso cai rau cov neeg ua haujlwm hauv cov kav dej kom ua tiav girth welds sai dua thiab kho tsawg dua.

High Dimensional Precision rau Alignment

API 5L specifications nruj nruj rau cov yeeb nkabtxoj kab uas hla, phab ntsa thickness, thiab ncaj.

Qhov txiaj ntsig:Thaum tso cov mais ntawm cov kav dej, qhov sib xws yog qhov tseem ceeb. Qhov tseeb qhov ntev kom ntseeg tau tias cov yeeb nkab xaus zoo kawg nkaus thaum lub sij hawm haum- rau orbital lossis phau ntawv vuam. Qhov no yuav txo tau cov teeb meem "hi-lo" (misalignment), uas yog thawj qhov ua rau muaj kev ntxhov siab thiab ua tsis tau tiav ntxov hauv cov kab siab - siab.

Manufacturing Versatility (SMLS vs. Welded)

API 5L muab cov qauv sib koom ua ke rau ob qho tib siSeamless (SMLS)thiabWelded (ERW, LSAW, SSAW)txheej txheem.

Qhov txiaj ntsig:Qhov no tso cai rau cov engineers xaiv tus nqi tshaj plaws -txoj kev tsim khoom zoo raws li qhov project qhov ntsuas tshwj xeeb.

Seamlessyog siv rau ultra-siab-siab me- kab kab.

LSAWyog siv rau loj - txoj kab uas hla, tuab - phab ntsa siab - siab kis.

SSAWmuaj peev xwm siv nyiaj -kev daws teeb meem rau loj- txoj kab uas hla, qis dua - thauj dej los yog roj.

Yuav tsum tau kuaj dab tsi rau API 5L Kab Yeeb?

Hydrostatic Test
Kev ntsuam xyuas hydrostatic yog ib hom kev ntsuas siab uas feem ntau siv thaum lub sij hawm tsim cov kav dej. Kev ntsuam xyuas yog siv los kuaj xyuas cov dej xau hauv cov vuam seam lossis cov yeeb nkab lub cev. Txhawm rau ua qhov kev sim, dej tau muab tso rau hauv cov yeeb nkab kom txog thaum nws nce mus txog qhov ntsuas tau ua ntej. Cov yeeb nkab yog tom qab ntawd saib xyuas rau txhua qhov xau. Yog tias pom muaj cov pa xau, cov yeeb nkab yuav tsum tau kho lossis hloov. Kev ntsuam xyuas hydrostatic yog ib qho tseem ceeb ntawm kev tswj xyuas zoo uas yuav pab kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov kav dej.

Bending Test
Kev kuaj khoov yog ib hom kev kuaj xyuas zoo uas tau ua thaum lub sij hawm tsim cov yeeb nkab steel. Lub hom phiaj ntawm kev xeem yog los xyuas cov kab nrib pleb hauv cov welds, nrog rau kev ntsuas lub zog ntawm cov hlau. Txhawm rau ua qhov kev sim, ib qho piv txwv ntawm cov yeeb nkab yog khoov rau hauv U-puab. Cov hlau yog tom qab ntawd tshuaj xyuas cov kab nrib pleb lossis lwm yam cim ntawm kev qaug zog. Yog tias pom muaj, tag nrho cov kav hlau yuav raug muab pov tseg thiab yuav ua ib pawg tshiab. Txawm li cas los xij, yog tias qhov kev sim khoov tau ua tiav, cov kav hlau yuav raug pom zoo siv.

Flattening Test
Ib qho kev sim flattening yog ib qho kev ntsuam xyuas cov kab yeeb nkab steel uas ntsuas lub raj hlau tsis kam rau deformation thiab tawg hauv kev ntxhov siab. Nws yog ib qho tseem ceeb tswj kev ntsuas uas pab kom cov hlau siv nyob rau hauv cov yeeb nkab cov khoom yog lub siab tshaj plaws ua tau zoo. Qhov kev sim no muaj kev siv lub siab rau lub raj steel kom txog thaum nws deforms lossis tawg. Kev ntsuas flattening yuav qhia tau cov yeeb nkab tsis kam mus rau longitudinal thiab circumferential cracking. Cov txiaj ntsig ntawm qhov kev ntsuam xyuas pab txiav txim siab cov hlau lub zog thiab ductility, ob qho khoom tseem ceeb rau cov hlau siv hauv kev siv cov yeeb nkab kab. Kev ntsuam xyuas flattening tsuas yog ib qho ntawm ntau qhov kev tswj xyuas zoo uas siv thaum lub sij hawm steel kab yeeb nkab tsim, tab sis lawv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov khoom kawg.

CVN Impact Test
CVN cuam tshuam kev ntsuas yog qhov ntsuas kub uas tau ua thaum lub sij hawm cov yeeb nkab tsim kom ntseeg tau tias cov khoom siv ntawm cov yeeb nkab. Qhov kev ntsuam xyuas yog ua los ntawm peb txoj haujlwm sib txawv ntawm cov yeeb nkab: lub cev, vuam seam, thiab cua sov- thaj tsam cuam tshuam. Cov txiaj ntsig ntawm kev sim yog siv los txiav txim siab Charpy V-qhov cuam tshuam rau lub zog ntawm cov yeeb nkab. Qhov kev ntsuam xyuas CVN yog ib qho tseem ceeb tswj kev ntsuas kev tsim cov yeeb nkab, thiab nws yuav tsum tau los ntawm American Petroleum Institute (API) thiaj li ua tau raws li nws cov qauv.

DWTT
Qhov kev sim DWTT, lossis poob- hnyav kua muag ntsuas, tau teev nyob rau hauv API 5L pipeline ntau lawm specification. Hauv qhov kev sim no, qhov hnyav loj tau poob mus rau qhov ua ntej -tsis muaj zog taw tes ntawm cov qauv ntawm cov yeeb nkab. Qhov tshwm sim tawg yog tshuaj xyuas kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua rau kev coj tus cwj pwm ductile fracture. Qhov kev sim no tseem ceeb heev vim tias nws yuav pab kom ntseeg tau tias cov kav dej yuav tuaj yeem tiv taus qhov kev ntxhov siab ntawm kev thauj mus los thiab teeb tsa yam tsis muaj kev tawg. Raws li qhov tshwm sim, DWTT xeem yog ib feem tseem ceeb ntawm cov txheej txheem tswj kom zoo rau cov kav dej loj.
