Emhlabeni jikelele, ukukhishwa kukawoyela negesi olwandle oluphakeme kudinga izixazululo zamapayipi ezintsha neziyinkimbinkimbi kusetshenziswa izinto ezisezingeni eliphezulu. Akuseyona into engavamile ngezinkampani zikawoyela ukumba uwoyela ngaphezu kwamamitha ayi-10,000 ngaphansi komhlaba.
Ukuqinisekisa inzuzo yesikhathi eside, noma yimuphi umthombo udinga ukutholakala okungenani iminyaka engama-25. I-Schoeller Werk eJalimane inikela ekuqinisekisweni kwekhwalithi nokuhlela okudingekayo ngemigqa yayo yokulawula imisebenzi esindayo kanye namapayipi okujova amakhemikhali embonini yasogwini. Ukwakheka kwabo kobuchwepheshe kubavumela ukuthi bamelane hhayi nje kuphela nezimo zokucindezela okukhulu ezivame kakhulu olwandle olujulile, kodwa futhi namazinga okushisa aphezulu kakhulu kanye nemithombo yoketshezi egqwalisayo.
Emhlabeni jikelele, imishini yokugaya engaphandle kwezwe engaphezu kuka-2,000 kanye neminye imithombo eminingi ezimele iyaqhubeka nokukhiqiza uwoyela negesi. Imishini yobuchwepheshe yalezi zitshalo ibeka izidingo eziphezulu kakhulu kubahlinzeki abakhethwe ngokucophelela embonini yensimbi engagqwali. ISchoeller Werk yathatha le nselele olwandle eminyakeni engama-35 eyedlule futhi ibilokhu ihola embonini iminyaka eminingi. Esizindeni sayo e-Eifel, inkampani ayikhiqizi nje kuphela amapayipi ezimboni ezahlukahlukene, kodwa futhi inikeza nezixazululo ezingcono kakhulu zobuchwepheshe zemishini yokugaya.
Enkampanini eyodwa, i-TCO Norway kuphela, i-Schoeller Werk, umhlinzeki wezinsizakalo enkampanini kawoyela kahulumeni waseNorway, ihlinzeke ngamapayipi angaphezu kwamamitha angu-500,000 selokhu yawina i-oda lamakhasimende entwasahlobo ka-2014. Inhliziyo yalobu budlelwano ibalwa ngama-alloy asezingeni eliphezulu asekelwe ku-nickel. 825 kanye no-625. Kukhona namapayipi e-austenitic enziwe ngensimbi engagqwali ye-grade 316 Ti. Amapayipi alethiwe ahlabe umxhwele kakhulu i-Statoil kangangokuthi iwachaze njengendinganiso yencazelo yawo. Ngaphezu kwezinto eziningi, kudingeka kwenziwe ububanzi obukhulu bobubanzi nobukhulu bodonga - amapayipi e-Schoeller ohlobo lwe-Sierra amboza wonke amathuba. Umklamo wamapayipi kanye nokuhlolwa kwekhwalithi okuhambisanayo kwenza ikhambi lokugcina likwazi ukumelana nezingcindezi zangaphakathi ezifika kumabha angu-2,500 ngaphandle kobunzima. Ngaphezu kwalokho, izinto ezisezingeni eliphezulu, kanye nekhwalithi ephezulu yendawo etholakala enkambisweni yokudweba ucingo, imelana nemiphumela yamanzi anosawoti kanye nezinye izinto ezivuthayo.
Esinye sezici zeshubhu le-plug-in ukugoba kwalo okunembile ngokwejiyometri kanye nekhwalithi ephezulu yokushisela. Ngokuyisisekelo, izinto eziyisisekelo aziyona into ebalulekile, futhi amapayipi angawodwa angafika kumamitha angu-2,000 angenziwa. Ama-mandrel angaphakathi (ama-plug) asetshenziselwa ukushelela ingaphakathi lama-welds amade. Uma ehlanganiswe ne-mandrel yangaphandle, ingxenye yokuqala yeshubhu ingancishiswa ngo-50%. Sekukonke, lesi yisisombululo esishisiwe ngobude esinikeza umbono weshubhu elingenamthungo. Ukubuka isakhiwo esincane sezinto kwembule ukuthi i-weld yayingabonakali ngisho nangemva kokuba ipayipi selidonswe. Izimfanelo ezinjengalezi zingamaphuzu abalulekile kumakhasimende ase-offshore kaSchoeller Werk.
Imboni yasogwini isebenzisa la mapayipi njengemigqa yokulawula i-hydraulic yama-valve okuphepha kanye nokupompa amakhemikhali ezindaweni zokugcina uwoyela. Ngale ndlela, asekela yonke inqubo yokukhipha. Amapayipi okufaka avumela abaqhubi bemishini ukuthi bahlose amakhemikhali ukuze bancibilikise uphethiloli, ngaleyo ndlela bathuthukise izici zokugeleza kwawo. Enqubweni yokukhiqiza eyinkimbinkimbi, amapayipi ahlolwa ngezindlela ezahlukene ngaphambi kokufakwa ukuqinisekisa ikhwalithi evelele yomkhiqizo. Imichilo yensimbi ihlanganiswa ndawonye ngemithungo emide kusetshenziswa inqubo yokushisela igesi ye-tungsten inert (TIG) bese igoqwa ibe ngamapayipi. Ngaphezu kokuhlolwa kwamanje kwe-eddy okuphoqelekile, ipayipi libe selihlolwa umoya ongaphansi kwamanzi (AUW noma "bubble"). Ipayipi licwiliswa emanzini futhi ligcwaliswe umoya ofinyelela kumabha angu-210. Yenza ukuhlolwa okubonakalayo kulo lonke ubude bamapayipi ukuze uhlole ukuthi avalwe yini. Ukuze iSchoeller Werk ikwazi ukunikeza amakhasimende ayo ubude obudingekayo obungu-15,000m nangaphezulu, amapayipi ngamanye ahlanganiswa ndawonye ngesitimela futhi ahlolwe nge-X-ray ukuze kuhlolwe ukuthi ama-weld esitimela awangeni moya futhi awanayo imigodi yomoya.
I-Schoeller Werk iphinde yenze izivivinyo ze-hydraulic kumapayipi okulawula nawokujova ngaphambi kokulethwa kumakhasimende. Lokhu kuhilela ukugcwalisa ikhoyili eqediwe ngowoyela we-hydraulic bese ifakwa ekucindezelweni okufika ku-2,500 bar ukuze ilingise izimo ezimbi kakhulu ezivame ukuhlangatshezwana nazo emisebenzini yasogwini lolwandle.
Ngaphezu kokukhiqiza amapayipi ahlanzekile, iSchoeller Werk iphinde inikeze amakhasimende embonini yasogwini iphakheji yesevisi ephelele, isibonelo ukufakwa kwamapayipi ane-plastic sheathing kulokho okubizwa ngokuthi ama-flat packs. Lokhu kusho ukuthi i-tube bundle ingaxhunywa ku-extraction tube futhi ivikelwe ekugobeni nasekuncinweni. Ezinye izinsizakalo zifaka phakathi ukuhlanza nokugcwalisa amapayipi. Lapha, ingaphakathi le-pipe lihlanzwa ngoketshezi lwe-hydraulic kuze kube yilapho uketshezi lufinyelela ezingeni elithile le-ISO noma le-SAE purity. Uketshezi oluhlungiwe ngale ndlela lungahlala epayipini uma ikhasimende lilufuna, okusho ukuthi umsebenzisi unomkhiqizo ongasetshenziswa. Ngaphezu kwalokho, ama-tube bundle angafakelwa izintambo noma izintambo zokusekela zensimbi engagqwali. Ngaphezu kwalokho, ngenxa yobuso obungaphakathi obubushelelezi, i-plug-in tube nayo ifaneleka kakhulu ukusetshenziswa njengomsele wokudlulisa izintambo ze-optical.
ISchoeller Werk ijoyina imakethe yamazwe ngamazwe ekubambisaneni kwayo nemboni yasogwini lolwandle. Ngaphezu kweNorway ne-United Kingdom eduze noLwandle Olusenyakatho lwaseYurophu, iRussia, iSaudi Arabia, i-United Arab Emirates, i-Afrika, i-Asia, i-Australia kanye neNingizimu Melika ziphakathi kwezindawo eziqondiwe kakhulu zokusetshenziswa kwemigqa yokulawula yeSchoeller kanye namapayipi okujova ngamakhemikhali.
