Emhlabeni wonke, ukukhiqizwa kukawoyela negesi phesheya kwezilwandle kudinga izixazululo zamapayipi ezintsha neziyinkimbinkimbi kusetshenziswa izinto ezisezingeni eliphezulu.Akusajwayelekile ukuthi izinkampani zikawoyela zimba uwoyela ngaphezu kwamamitha ayi-10 000 ngaphansi komhlaba.
Ukuqinisekisa inzuzo yesikhathi eside, noma iyiphi insiza kufanele isetshenziswe okungenani iminyaka engama-25. I-Schoeller Werk yaseJalimane yenza igalelo layo kukhwalithi edingekayo kanye nesiqiniseko sokuhlela ngamapayipi ayo okulawula umsebenzi osindayo kanye namapayipi omjovo amakhemikhali emboni yasogwini. I-Schoeller Werk yaseJalimane yenza igalelo layo kukhwalithi edingekayo kanye nesiqiniseko sokuhlela ngamapayipi ayo okulawula umsebenzi osindayo kanye namapayipi omjovo amakhemikhali emboni yasogwini.Inkampani yaseJalimane i-Schoeller Werk inikela kwikhwalithi edingekayo kanye nokuhlela ngokukhiqiza izintambo zokulawula umsebenzi osindayo kanye namapayipi omjovo wamakhemikhali embonini yasogwini.I-Schoeller Werk yaseJalimane inikela kwikhwalithi edingekayo kanye nokuhlela ngemigqa yayo yokulawula umsebenzi osindayo namapayipi okujova ngamakhemikhali embonini yasogwini.Umklamo wabo wobuchwepheshe ubavumela ukuthi bangakwazi ukumelana nezimo zokucindezela okwedlulele ezitholakala olwandle olujulile, kodwa futhi namazinga okushisa aphezulu kakhulu kanye nemithombo ye-liquid ebolayo.
Emhlabeni wonke, izinsimbi zokumba ezingaphezu kuka-2,000 zasolwandle kanye nemithombo eminingi ezimele iqhubeka ikhiqiza uwoyela negesi.Imishini yobuchwepheshe yalezi zitshalo ibeka izidingo eziphezulu kakhulu kubahlinzeki bensimbi engagqwali abakhethwe ngokucophelela.USchoeller Werk uthathe inselelo olwandle eminyakeni engama-35 eyedlule futhi ube ngumholi kulo mkhakha iminyaka eminingi.Isizinda senkampani e-Eifel asikhiqizi nje kuphela amapayipi ezimboni ezihlukahlukene, kodwa futhi sihlinzeka ngezixazululo ezithuthuke kakhulu ngobuchwepheshe zokumba izinsimbi.
Enkampanini eyodwa, i-TCO Norway, i-Schoeller Werk, umhlinzeki wesevisi enkampanini kawoyela yesifunda saseNorway, ilethe amapayipi angaphezu kuka-500,000 wamamitha kusukela ithola i-oda elivela kukhasimende entwasahlobo ka-2014. Lokhu kubambisana kusekelwe kuma-alloys asekelwe ku-nickel ekhwalithi ephezulu.825 kanye 625. Amashubhu ensimbi engenasici ye-Austenitic 316 Ti ayatholakala.Amapayipi alethiwe ayihlabe umxhwele i-Statoil kangangokuthi yawachaza njengezinga lokucaciswa kwawo.Ngaphezu kohlu olubanzi lwezinto, kufanele kukhiqizwe ububanzi obubanzi nobukhulu bodonga - amapayipi aseSierra Schöller ahlanganisa wonke amathuba.Idizayini yamapayipi kanye nokuhlolwa kwekhwalithi okuhlobene kuvumela isisombululo sokugcina ukumelana nezingcindezi zangaphakathi ezifika kubha engu-2500 ngaphandle kwezinkinga.Ngaphezu kwalokho, izinto ezisezingeni eliphezulu, kanye nekhwalithi engaphezulu ethuthukisiwe etholwe enqubweni yokudweba ngocingo, amelana namanzi anosawoti nezinye izindawo ezinokhahlo.
Esinye sezici zepayipi lokufaka ukugoba okunembile kwejometri kanye nekhwalithi ephezulu yokushisela.Empeleni, izinto eziyisisekelo azinandaba futhi amapayipi angawodwa afinyelela kumamitha angama-2000 ubude angakhiqizwa.Ama-mandrels angaphakathi (ama-plugs) asetshenziselwa ukulinganisa indawo yangaphakathi ye-seams longitudinal.Ngokuhambisana ne-mandrel yangaphandle, isigaba sokuqala sepayipi singancishiswa kuze kufike ku-50%.Sekukonke, lesi yisixazululo esishiselwe isikhathi eside esinikeza umbono wepayipi elingenamthungo.Ukubhekwa kwe-microstructure yezinto ezibonakalayo kubonise ukuthi i-weld yayingabonakali ngisho nangemva kokudonswa kwepayipi.Lezi zimfanelo ziyizinzuzo ezibalulekile kumakhasimende we-Schoeller Werk asogwini.
Embonini yasogwini, la mapayipi asetshenziswa njengezintambo zokulawula ugesi wamavalvu okusiza kanye nokumpompa amakhemikhali ezindaweni zokugcina uwoyela.Ngakho, basekela yonke inqubo yokukhipha.Amapayipi omjovo avumela ama-rig operators ukuthi aqondise amakhemikhali ukuze ancibilikise uwoyela, ngaleyo ndlela athuthukise izici zawo zokugeleza.Njengengxenye yenqubo yokukhiqiza eyinkimbinkimbi, amapayipi angaphansi kokuhlolwa okuhlukahlukene ngaphambi kokufakwa ukuze kuqinisekiswe ikhwalithi engavamile yomkhiqizo.Amapheshana ensimbi ashiselwa ndawonye kuma-longitudinal seams kusetshenziswa inqubo ye-tungsten inert gas welding (TIG) bese esongwa abe amashubhu.Ngokungeziwe ekuhlolweni kwamanje kwe-eddy okuyimpoqo, ishubhu libe selifakwa ngaphansi kokuhlolwa komoya ongaphansi kwamanzi (AUW noma “ibhamuza”).Ishubhu icwiliswa emanzini futhi igcwaliswe ngomoya ofinyelela ku-210 bar.Yenza ukuhlola okubonakalayo kubo bonke ubude bamapayipi ukuze uqinisekise ukuthi aqinile.Ukuze i-Schoeller Werk inikeze amakhasimende ayo ubude obudingekayo obungamamitha angu-15 000 noma ngaphezulu, amapayipi agijimayo ayashiselwa ndawonye futhi afakwe ama-X-ray ukuze kuhlolwe ukuthi amashisela aqinile yini nokuthi azikho yini izimbobo zomoya.
I-Schoeller Werk iphinde ihlole amapayipi okulawula nokucindezela ngogesi ngaphambi kokulethwa ekhasimendeni.Lokhu kuhlanganisa ukugcwalisa ikhoyili eqediwe ngowoyela we-hydraulic nokuyicindezela kubha engu-2,500 ukulingisa izimo ezimbi kakhulu ngezinye izikhathi okuhlangatshezwana nazo emisebenzini yasogwini.
Ngaphezu kokukhiqizwa kwamapayipi ahlanzekile, i-Schoeller Werk iphinde inikeze amakhasimende embonini yasolwandle iphakheji yesevisi ephelele, efana nokuvala amapayipi anezikhwama zepulasitiki kulokho okubizwa ngokuthi amaphakethe flat.Lokhu kusho ukuthi inqwaba yeshubhu ingaxhunywa kushubhu yokukhipha futhi ivikelwe ekugobeni nasekumpintsheni.Ezinye izinsiza zihlanganisa ukushaywa kanye nokugcwalisa amapayipi.Lapha, ingaphakathi lepayipi ligezwa ngoketshezi olusebenza ngamanzi kuze kube yilapho uketshezi lufika ezingeni elithile le-ISO noma le-SAE lokuhlanzeka.Uketshezi oluhlungiwe kanjalo lungahlala epayipini uma ikhasimende lilufuna, okungukuthi umsebenzisi unomkhiqizo azowusebenzisa.Ngaphezu kwalokho, ama-tube bundles angahlinzekwa ngezintambo zensimbi engagqwali noma izintambo ezithwalayo.Ngaphezu kwalokho, ngenxa yendawo yangaphakathi ebushelelezi, ithubhu yokufaka nayo ifaneleka kakhulu ukusetshenziswa njengendlela yokudlulisa izintambo ze-optical.
U-Schoeller Werk ungena emakethe yamazwe ngamazwe ngokubambisana nemboni ye-offshore. Ngaphandle kweNorway neGreat Britain ngaseNorth Sea eYurophu, eRussia, eSaudi Arabia, e-UAE, e-Afrika, e-Asia, e-Australia naseNingizimu Melika zonke zibalwa phakathi kwezifunda ezibalulekile okuhloswe ngazo ukusetshenziswa kwe-Schoeller control-line & chemical-injection pipes.
