Nyob ib ncig ntawm lub ntiaj teb no, kev rho tawm cov roj thiab roj nyob rau hauv lub hiav txwv siab yuav tsum tau tsim thiab sophisticated piping kev daws teeb meem siv cov ntaub ntawv zoo.Nws tsis yog ib qho yooj yim rau cov tuam txhab roj tho rau cov roj ntau tshaj 10,000 meters hauv qab no.
Txhawm rau kom tau txais txiaj ntsig mus ntev, txhua qhov peev txheej yuav tsum muaj tsawg kawg yog 25 xyoo.Schoeller Werk hauv lub tebchaws Yelemes pab txhawb qhov tsim nyog thiab kev npaj kev ruaj ntseg nrog nws cov dej num hnyav thiab cov kav dej tshuaj txhaj tshuaj rau kev lag luam offshore.Lawv kev tsim qauv tso cai rau lawv tiv tsis tau tsuas yog cov huab cua siab hauv hiav txwv sib sib zog nqus, tab sis kuj kub heev thiab corrosive media.
Thoob plaws ntiaj teb, ntau tshaj 2,000 lub qhov dej tawm sab nrauv thiab ntau lub qhov dej ywj pheej tseem tab tom tsim cov roj thiab roj.Cov khoom siv ntawm cov nroj tsuag no muaj kev xav tau siab heev ntawm kev ua tib zoo xaiv cov neeg lag luam ntawm stainless hlau kev lag luam.Schoeller Werk coj qhov kev sib tw ntawm hiav txwv 35 xyoo dhau los thiab tau ua tus thawj coj hauv kev lag luam tau ntau xyoo.Ntawm nws lub hauv paus hauv Eifel, lub tuam txhab tsis tsuas yog rau kev tsim cov yeeb nkab, tab sis kuj muab ntau yam kev daws teeb meem. rigs.
Rau ib lub tuam txhab, TCO Norway ib leeg, Schoeller Werk, tus muab kev pabcuam rau Norway lub xeev cov roj tuam txhab, tau muab ntau tshaj 500,000 meters ntawm cov kav dej txij li tau txais kev txiav txim rau cov neeg siv khoom thaum lub caij nplooj ntoo hlav xyoo 2014.Lub plawv ntawm qhov kev koom tes no suav nrog cov khoom zoo nickel-raws li alloys.825 thiab 625.Theretic stainless steel tubes. Cov kav dej xa tau zoo siab rau Statoil ntau heev uas nws tau txhais lawv raws li tus qauv rau nws tus kheej specification.Ntxiv rau ntau yam khoom, ntau yam diameters thiab phab ntsa thicknesses yuav tsum tau tsim - Schoeller hlab ntawm Sierra hom npog tag nrho cov possibilities.Cov kav dej tsim thiab cov kev xeem zoo sib xws ua kom muaj kev sib tw kawg ntawm 0. cov khoom siv zoo, ua ke nrog kev txhim kho saum npoo zoo tau los ntawm cov txheej txheem kos duab hlau, tiv taus cov teebmeem ntawm cov dej ntsev thiab lwm yam kev tawm tsam.
Ib tug ntawm cov yam ntxwv ntawm lub plug-in raj yog nws geometrically meej curvature thiab siab welding zoo.Hauv txoj cai, cov khoom siv hauv paus tsis yog qhov tseem ceeb, thiab ib lub kav dej ntev txog li 2,000 meters tuaj yeem tsim tau.Internal mandrels (plugs) yog siv los ua kom du sab hauv ntawm longitudinal welds.Combined nrog ib tug sab nraud mandrel yuav txo tau 5%. Nyob rau hauv tag nrho, qhov no yog ib tug longitudinally welded tov uas muab lub tswv yim ntawm ib tug seamless raj.Saib lub microstructure ntawm cov ntaub ntawv qhia tias lub weld twb NW nyuam qhuav ntes tau txawm tias tom qab cov yeeb nkab tau kos.Tej yam ntxwv xws li cov no yog cov ntsiab lus tseem ceeb ntxiv rau Schoeller Werk cov neeg sab nrauv.
Kev lag luam offshore siv cov kav dej no ua cov kab tswj hydraulic rau kev nyab xeeb li qub thiab siv cov tshuaj rau hauv cov roj reservoirs.Qhov no, lawv txhawb nqa tag nrho cov txheej txheem rho tawm.Cov raj tso cai rau cov tswv lag luam txhawm rau tsom cov tshuaj rau liquefy roj av, yog li txhim kho nws cov yam ntxwv ntws.Nyob rau hauv cov txheej txheem tsim, cov kav dej tau raug rau ntau yam kev ntsuam xyuas ua ntej kev teeb tsa los xyuas kom meej cov khoom lag luam zoo. Cov seams siv cov txheej txheem tungsten inert gas (TIG) thiab tom qab ntawd dov mus rau hauv cov raj.Ntxiv rau qhov yuav tsum tau ua tam sim no, lub raj yuav raug rau cov cua hauv qab dej (AUW lossis " npuas"). Ua haujlwm kom muaj peev xwm muab tau nws cov neeg siv khoom nrog qhov ntev ntawm 15,000m thiab siab dua, cov kav dej ib leeg yog rail welded ua ke thiab X-rayed los xyuas tias cov rail welds yog airtight thiab tsis muaj cua qhov.
Schoeller Werk tseem ua cov kev ntsuam xyuas hydraulic ntawm kev tswj thiab txhaj cov kav dej ua ntej xa mus rau cov neeg siv khoom.Qhov no suav nrog kev ua tiav cov kauj vab nrog cov roj hydraulic thiab ua rau nws raug siab txog li 2,500 bar los simulate cov xwm txheej huab cua qee zaum ntsib hauv kev ua haujlwm sab nrauv.
Ntxiv nrog rau kev tsim cov yeeb nkab ntshiab, Schoeller Werk tseem muab cov neeg siv khoom hauv kev lag luam tawm sab nrauv ib pob kev pabcuam, piv txwv li cov khoom siv hauv cov kav dej nrog cov yas sheathing hauv lub npe hu ua flat packs.Qhov no txhais tau hais tias lub hnab ntim cov raj tuaj yeem txuas nrog lub raj xa tawm thiab tiv thaiv kev khoov thiab pinching.Lwm cov kev pabcuam suav nrog kev lim dej thiab ntim cov dej ntws hauv cov yeeb nkab kom txog thaum cov dej ntws tawm. ib qho ISO lossis SAE purity level.Fluid filtered nyob rau hauv txoj kev no tuaj yeem nyob twj ywm hauv cov yeeb nkab yog tias tus neeg siv khoom xav tau, txhais tau tias tus neeg siv khoom muaj cov khoom siv tuaj yeem siv tau. Tsis tas li ntawd, cov khoom siv lub raj tuaj yeem nruab nrog cov xov hlau lossis stainless hlau txhawb nqa cables. Ntxiv rau, vim yog qhov zoo nkauj sab hauv, lub plug-in tube kuj yog qhov tsim nyog rau kev siv los ntawm cov khoom siv kho qhov muag.
Schoeller Werk koom nrog kev lag luam thoob ntiaj teb hauv nws txoj kev koom tes nrog kev lag luam offshore.Ntxiv rau Norway thiab United Kingdom nyob ze ntawm European North Hiav Txwv, Russia, Saudi Arabia, United Arab Emirates, Africa, Asia, Australia thiab South America yog ib lub hom phiaj tseem ceeb rau kev siv Schoeller tswj kab thiab tshuaj txhaj tshuaj yeeb nkab.
