Thoob plaws lub ntiaj teb no, kev tsim cov roj thiab cov roj tawm sab nrauv yuav tsum muaj cov kev daws teeb meem tshiab thiab cov kav dej uas siv cov khoom zoo.Nws tsis yog qhov tsis yooj yim rau cov tuam txhab roj tho roj ntau dua 10,000 meters hauv qab ntawm qhov chaw.
Txhawm rau kom tau txais txiaj ntsig mus ntev, txhua qhov peev txheej yuav tsum tau siv tsawg kawg 25 xyoo. Lub teb chaws Yelemees's Schoeller Werk ua rau nws tus kheej pab txhawb rau qhov tsim nyog zoo thiab kev npaj kev ruaj ntseg nrog nws txoj haujlwm hnyav tswj-kab & tshuaj-txhaj tshuaj yeeb nkab rau kev lag luam offshore. Lub teb chaws Yelemees's Schoeller Werk ua rau nws tus kheej pab txhawb rau qhov tsim nyog zoo thiab kev npaj kev ruaj ntseg nrog nws txoj haujlwm hnyav tswj-kab & tshuaj-txhaj tshuaj yeeb nkab rau kev lag luam offshore.Lub tuam txhab German Schoeller Werk pab txhawb rau qhov yuav tsum tau ua kom zoo thiab kev npaj los ntawm kev tsim cov kab ua haujlwm hnyav thiab cov kav dej tshuaj rau kev lag luam offshore.Schoeller Werk nyob rau hauv lub teb chaws Yelemees pab txhawb rau qhov yuav tsum tau ua kom zoo thiab kev npaj nrog nws cov luag hauj lwm hnyav tswj kab thiab tshuaj txhaj yeeb nkab rau kev lag luam offshore.Lawv cov kev tsim qauv tso cai rau lawv tiv tsis tau tsuas yog cov huab cua siab nyob rau hauv lub hiav txwv sib sib zog nqus, tab sis kuj kub heev thiab corrosive kua xov xwm.
Thoob plaws ntiaj teb, ntau dua 2,000 qhov chaw nres nkoj ntawm ntug dej hiav txwv thiab ntau lub qhov dej ywj pheej tsis tu ncua tsim roj thiab roj.Cov cuab yeej cuab tam ntawm cov nroj tsuag no muaj kev xav tau siab heev ntawm kev ua tib zoo xaiv cov khoom lag luam stainless hlau.Schoeller Werk coj qhov kev sib tw ntawm hiav txwv 35 xyoo dhau los thiab tau ua tus thawj coj hauv kev lag luam rau ntau xyoo.Lub tuam txhab lub hauv paus hauv Eifel tsis yog tsuas yog tsim cov kav dej rau ntau yam kev lag luam, tab sis kuj muab cov kev daws teeb meem zoo tshaj plaws rau cov khoom siv drilling.
Rau ib lub tuam txhab, TCO Norway, Schoeller Werk, tus muab kev pabcuam rau Norway lub xeev lub tuam txhab roj, tau xa ntau tshaj 500,000 meters ntawm cov raj xa dej txij li tau txais kev txiav txim los ntawm cov neeg siv khoom thaum lub caij nplooj ntoo hlav xyoo 2014. Qhov kev sib koom tes no yog ua los ntawm cov nickel zoo li alloys.825 thiab 625. Austenitic 316 Ti stainless hlau raj kuj muaj.Cov kav xa dej tau qhuas Statoil ntau heev uas lawv tau teeb tsa lawv ua tus qauv rau lawv tus kheej tshwj xeeb.Ntxiv nrog rau ntau yam khoom siv, ntau hom kab uas hla thiab phab ntsa tuab yuav tsum tau tsim - Sierra Schöller cov kav dej npog txhua qhov muaj peev xwm.Kev tsim cov kav dej thiab cov kev ntsuam xyuas zoo tso cai rau qhov kev daws teeb meem kawg los tiv thaiv kev ntxhov siab txog li 2500 bar yam tsis muaj teeb meem.Tsis tas li ntawd, cov khoom siv zoo, ua ke nrog kev txhim kho saum npoo zoo tau txais los ntawm cov txheej txheem kos duab hlau, tiv taus dej ntsev thiab lwm qhov chaw nruj heev.
Ib qho ntawm cov yam ntxwv ntawm cov yeeb nkab ntxig yog nws cov geometrically precision dabtsi yog khoov thiab vuam zoo.Raws li txoj cai, cov khoom siv hauv paus tsis muaj teeb meem thiab ib lub kav dej ntev txog 2000 meters tuaj yeem tsim tau.Internal mandrels (plugs) yog siv rau theem sab hauv ntawm cov seams longitudinal.Nyob rau hauv kev sib xyaw nrog rau sab nraud mandrel, thawj cov yeeb nkab hla ntu tuaj yeem raug txo kom txog li 50%.Zuag qhia tag nrho, qhov no yog ib tug longitudinally welded tov uas muab lub tswv yim ntawm ib tug seamless yeeb nkab.Kev soj ntsuam ntawm microstructure ntawm cov khoom pom tau hais tias qhov vuam tsis tshua pom txawm tias tom qab cov yeeb nkab tau kos.Cov kev zoo no yog cov txiaj ntsig tseem ceeb rau Schoeller Werk cov neeg siv khoom sab nrauv.
Hauv kev lag luam offshore, cov kav dej no tau siv los ua cov kab tswj hydraulic rau kev pab li qub thiab siv cov tshuaj mus rau hauv cov roj reservoirs.Yog li, lawv txhawb nqa tag nrho cov txheej txheem rho tawm.Cov kav dej txhaj tso cai rau cov neeg ua haujlwm rig coj cov tshuaj mus rau liquefy roj, yog li txhim kho nws cov yam ntxwv ntws.Raws li ib feem ntawm cov txheej txheem tsim khoom, cov kav dej tau raug rau ntau yam kev ntsuam xyuas ua ntej kev teeb tsa los lav qhov tshwj xeeb zoo ntawm cov khoom.Cov hlau strips yog welded ua ke ntawm longitudinal seams siv tungsten inert gas welding (TIG) txheej txheem thiab ces twisted rau hauv cov hlab.Ntxiv rau qhov yuav tsum tau ntsuas tam sim no, lub raj xa mus rau qhov ntsuas cua hauv qab dej (AUW lossis " npuas").Lub raj yog immersed nyob rau hauv dej thiab ntim nrog cua mus txog 210 bar.Ua ib qho kev soj ntsuam pom raws tag nrho qhov ntev ntawm cov kav dej kom ntseeg tau tias lawv nruj.Txhawm rau Schoeller Werk muab nws cov neeg siv khoom nrog qhov ntev ntawm 15,000 m lossis ntau dua, cov kav dej ib leeg yog welded ua ke ntawm cov ntsia hlau thiab X-rayed los xyuas tias cov rail welds yog nruj thiab tsis muaj qhov cua.
Schoeller Werk kuj hydraulically kuaj tswj thiab txhaj cov kav dej ua ntej xa mus rau cov neeg siv khoom.Qhov no suav nrog kev ua tiav cov kauj ruam nrog cov roj hydraulic thiab nias nws mus rau 2,500 bar kom simulate cov xwm txheej huab cua qee zaum ntsib hauv kev ua haujlwm sab nraud.
Ntxiv nrog rau kev tsim cov yeeb nkab huv si, Schoeller Werk tseem muab cov neeg siv khoom hauv kev lag luam tawm sab nrauv ib pob ntawm cov kev pabcuam, xws li kev sib khi cov kav dej nrog cov hnab yas hauv lub npe hu ua flat packs.Qhov no txhais tau hais tias lub raj ntim khoom tuaj yeem txuas nrog lub raj xa tawm thiab tiv thaiv los ntawm kev khoov thiab pinching.Lwm cov kev pabcuam muaj xws li dej ntws thiab ntim cov kav dej.Ntawm no, sab hauv ntawm cov yeeb nkab yog flushed nrog hydraulic kua kom txog thaum cov kua dej nce mus txog ib qho ISO lossis SAE qib kev huv.Cov kua lim hauv txoj kev no tuaj yeem nyob hauv cov yeeb nkab yog tias tus neeg siv khoom xav tau, piv txwv li tus neeg siv khoom siv.Tsis tas li ntawd, cov hnab ntim cov raj tuaj yeem muab nrog cov hlau tsis muaj steel hlau lossis nqa cov cables.Tsis tas li ntawd, vim yog qhov zoo nkauj sab hauv, lub raj ntxig kuj yog qhov tsim nyog rau kev siv los ua cov kav dej rau kev sib kis ntawm optical cables.
Schoeller Werk nkag mus rau hauv kev lag luam thoob ntiaj teb hauv kev koom tes nrog kev lag luam offshore. Sib nrug los ntawm Norway thiab Great Britain nyob ib ncig ntawm North Hiav Txwv hauv Tebchaws Europe, Russia, Saudi Arabia, UAE, Africa, Asia, Australia thiab South America tag nrho suav nrog cov cheeb tsam tseem ceeb rau kev siv Schoeller tswj-kab & tshuaj txhaj tshuaj. Sib nrug los ntawm Norway thiab Great Britain nyob ib ncig ntawm North Hiav Txwv hauv Tebchaws Europe, Russia, Saudi Arabia, UAE, Africa, Asia, Australia thiab South America tag nrho suav nrog cov cheeb tsam tseem ceeb rau kev siv Schoeller tswj-kab & tshuaj txhaj tshuaj.Ntxiv rau Norway thiab UK nyob ib ncig ntawm North Hiav Txwv hauv Tebchaws Europe, Russia, Saudi Arabia, UAE, Africa, Asia, Australia thiab South America, lawv txhua tus yog cov cheeb tsam tseem ceeb rau kev siv Schoeller pipelines rau kev tswj cov kab thiab cov kav dej rau kev txhaj tshuaj.Ntxiv rau Norway thiab United Kingdom ze ntawm European North Hiav Txwv, Russia, Saudi Arabia, United Arab Emirates, Africa, Asia, Australia thiab South America yog qee lub hom phiaj tseem ceeb rau Schoeller tswj kab thiab cov kav dej tshuaj.
