Padziko lonse lapansi, kukumba mafuta ndi gasi m'nyanja zazikulu kumafuna njira zatsopano komanso zamakono zopangira mapaipi pogwiritsa ntchito zipangizo zapamwamba. Sizachilendonso kuti makampani opanga mafuta akumba mafuta pamtunda woposa mamita 10,000 pansi pa nthaka.
Kuti atsimikizire phindu la nthawi yayitali, chuma chilichonse chiyenera kugwiritsidwa ntchito kwa zaka zosachepera 25. Schoeller Werk ku Germany imathandizira pakupanga zinthu zabwino komanso zokonzekera bwino pogwiritsa ntchito njira zake zowongolera katundu wolemera komanso mapaipi opangira mankhwala kwa makampani akunyanja. Kapangidwe kawo kaukadaulo kamawathandiza kupirira osati kokha kupsinjika kwakukulu komwe kumapezeka m'nyanja yakuya, komanso kutentha kwambiri komanso zinthu zowononga madzi.
Padziko lonse lapansi, zida zopitilira 2,000 za m'mphepete mwa nyanja ndi zitsime zina zambiri zodziyimira pawokha zikupanga mafuta ndi gasi nthawi zonse. Zipangizo zaukadaulo za mafakitale awa zimafuna kwambiri ogulitsa osankhidwa mosamala amakampani opanga zitsulo zosapanga dzimbiri. Schoeller Werk adakumana ndi vutoli panyanja zaka 35 zapitazo ndipo wakhala mtsogoleri mumakampaniwa kwa zaka zambiri. Kampaniyo ku Eifel sikuti imangopanga mapaipi amakampani osiyanasiyana, komanso imapereka mayankho apamwamba kwambiri a zida zobowolera.
Kampani imodzi, TCO Norway yokha, Schoeller Werk, kampani yopereka chithandizo ku kampani yamafuta ya boma ku Norway, yapereka mapaipi opitilira mamita 500,000 kuyambira pomwe idapambana oda ya kasitomala m'chaka cha 2014. Mtima wa mgwirizanowu umawerengedwa ndi ma alloys apamwamba kwambiri okhala ndi nickel.825 ndi 625. Palinso machubu a austenitic opangidwa ndi chitsulo chosapanga dzimbiri cha 316 Ti. Mapaipi omwe aperekedwa asangalatsa kwambiri Statoil kotero kuti awafotokoza ngati muyezo wa zomwe akufuna. Kuphatikiza pa zipangizo zosiyanasiyana, makulidwe osiyanasiyana a makoma ayenera kupangidwa - machubu a Schoeller a Sierra amaphimba zonse zomwe zingatheke. Kapangidwe ka mapaipi ndi mayeso ofanana a khalidwe zimathandiza kuti yankho lomaliza lipirire kupsinjika kwamkati mpaka mipiringidzo 2,500 mosavuta. Kuphatikiza apo, zinthu zapamwamba kwambiri, pamodzi ndi mawonekedwe abwino a pamwamba omwe amachokera ku njira yokokera waya, zimalimbana ndi zotsatira za madzi amchere ndi zinthu zina zamphamvu.
Chimodzi mwa zinthu zomwe zili mu chubu cholumikizira ndi kupindika kwake kolondola komanso mtundu wake wapamwamba wa welding. Mwachidule, maziko ake si chinthu chofunikira, ndipo mapaipi amodzi okwana mamita 2,000 amatha kupangidwa. Ma mandrel amkati (mapulagi) amagwiritsidwa ntchito kusalala mkati mwa ma weld a longitudinal. Kuphatikiza ndi mandrel akunja, gawo loyambira la chubucho lingachepe mpaka 50%. Zonse pamodzi, iyi ndi yankho lolumikizidwa lotalika lomwe limapereka chithunzi cha chubu chosasunthika. Kuwona kapangidwe kake ka zinthuzo kunawonetsa kuti weldyo sinali yodziwika bwino ngakhale chitolirocho chitakokedwa. Makhalidwe ngati awa ndi mfundo zofunika kwambiri kwa makasitomala akunyanja a Schoeller Werk.
Makampani ogulitsa zinthu m'mphepete mwa nyanja amagwiritsa ntchito mapaipi awa ngati mizere yowongolera ma hydraulic ya ma valve oteteza komanso popopera mankhwala m'malo osungira mafuta. Mwanjira imeneyi, amathandizira njira yonse yotulutsira. Machubu obayira amalola ogwiritsa ntchito zida kuti azitha kugwiritsa ntchito mankhwala kuti asungunule mafuta, motero amawongolera momwe amayendera. Mu njira yovuta yopangira, mapaipi amayesedwa mosiyanasiyana asanayikidwe kuti atsimikizire kuti zinthuzo ndi zabwino kwambiri. Zingwe zachitsulo zimalumikizidwa pamodzi ndi mipiringidzo yayitali pogwiritsa ntchito njira yolumikizira ya tungsten inert gas (TIG) kenako nkukulungidwa m'machubu. Kuphatikiza pa mayeso ofunikira a eddy current, chubucho chimayesedwa ndi mpweya wa pansi pa madzi (AUW kapena "bubble"). Chubucho chimamizidwa m'madzi ndikudzazidwa ndi mpweya mpaka 210 bar. Chitani kafukufuku wowoneka bwino m'litali lonse la machubu kuti muwone ngati atsekedwa. Kuti Schoeller Werk athe kupatsa makasitomala ake kutalika kofunikira kwa 15,000m ndi kupitirira apo, mapaipiwo amalumikizidwa pamodzi ndi X-ray kuti awonetsetse kuti ma weld a njanji ndi opanda mpweya komanso opanda mabowo a mpweya.
Schoeller Werk amachitanso mayeso a hydraulic pa mapaipi owongolera ndi obayira asanaperekedwe kwa kasitomala. Izi zimaphatikizapo kudzaza coil yomalizidwa ndi mafuta a hydraulic ndikuyika pamavuto okwana 2,500 bar kuti ayerekezere mikhalidwe yoopsa yomwe nthawi zina imakumana nayo pantchito zakunja.
Kuwonjezera pa kupanga mapaipi oyera, Schoeller Werk imapatsanso makasitomala omwe ali m'makampani akunyanja phukusi lathunthu lautumiki, mwachitsanzo kutsekeka kwa mapaipi okhala ndi pulasitiki mu zomwe zimatchedwa mapaketi athyathyathya. Izi zikutanthauza kuti phukusi la chubu likhoza kulumikizidwa ku chubu chochotsera ndikutetezedwa kuti lisapindike ndi kukanikiza. Ntchito zina zimaphatikizapo kutsuka ndi kudzaza mapaipi. Apa, mkati mwa chitolirocho mumatsukidwa ndi madzi a hydraulic mpaka madziwo atafika pamlingo wovomerezeka wa ISO kapena SAE. Madzi osefedwa mwanjira iyi amatha kukhalabe mu chitoliro ngati kasitomala akufuna, zomwe zikutanthauza kuti wogwiritsa ntchito ali ndi chinthu chomwe angagwiritsidwe ntchito. Kuphatikiza apo, mapaipi a chubu amatha kukhala ndi mawaya kapena zingwe zothandizira zitsulo zosapanga dzimbiri. Kuphatikiza apo, chifukwa cha pamwamba pake posalala, chubu cholumikizira ndi choyenera kwambiri kugwiritsidwa ntchito ngati njira yotumizira zingwe zowunikira.
Schoeller Werk ikugwirizana ndi msika wapadziko lonse lapansi mogwirizana ndi makampani akunyanja. Kuwonjezera pa Norway ndi United Kingdom pafupi ndi Nyanja ya Kumpoto ya ku Europe, Russia, Saudi Arabia, United Arab Emirates, Africa, Asia, Australia ndi South America ndi ena mwa madera omwe amagwiritsidwa ntchito kwambiri pogwiritsa ntchito zingwe zowongolera za Schoeller ndi mapaipi obayira mankhwala.
