Pasi rose, kucherwa kwemafuta negasi mugungwa guru kunoda nzira itsva uye dzepamusoro dzekugadzira mapaipi uchishandisa zvinhu zvemhando yepamusoro. Hazvichisiri zvisinganzwisisike kuti makambani emafuta achere mafuta ari pasi pemvura anopfuura mamita 10,000.
Kuti tive nechokwadi chekuti purofiti inoenderera mberi kwenguva refu, chero chinhu chinofanira kushandiswa kwemakore angangoita makumi maviri nemashanu. Schoeller Werk muGermany inobatsira pakuvimbisa hunhu uye kuronga kwakakosha netambo dzayo dzinorema dzekudzora uye mapaipi ekuisa mishonga yemakemikari kumaindasitiri ekunze. Dhizaini yavo yehunyanzvi inovabvumira kutsungirira kwete chete mamiriro ekumanikidzwa kwakanyanya ari mugungwa rakadzika, asiwo tembiricha yakakwira zvakanyanya uye ngura yemvura.
Pasi rose, matsime emvura anopfuura 2,000 pamwe nemamwe matsime akawanda akazvimirira ari kuramba achigadzira mafuta negasi. Midziyo yehunyanzvi yefekitori iyi inoda zvakanyanya vatengesi vakasarudzwa zvakanaka veindasitiri yesimbi isingatsvi. Schoeller Werk akatora dambudziko iri mugungwa makore makumi matatu nemashanu apfuura uye ave ari mutungamiriri muindasitiri kwemakore mazhinji. Pamuzinda wayo muEifel, kambani iyi haingogadziri mapaipi emaindasitiri akasiyana-siyana chete, asiwo inopa mhinduro dzehunyanzvi dzematangi ekuchera.
Kune imwe kambani, TCO Norway chete, Schoeller Werk, kambani yemafuta yehurumende yeNorway, yakapa mapaipi anopfuura 500,000 metres kubva payakahwina odha yevatengi muchirimo cha2014. Chinonyanya kukosha chekubatana uku ndechekuti machubhu emhando yepamusoro akagadzirwa ne nickel-based alloys.825 ne625. Kunewo machubhu e austenitic akagadzirwa nesimbi isina ngura ye grade 316 Ti. Mapaipi akapihwa akafadza Statoil zvekuti akaatsanangura sechiyero chezvaanofanira kutsanangura. Pamusoro pezvinhu zvakasiyana-siyana, dhayamita dzakasiyana-siyana uye ukobvu hwemadziro zvinofanirwa kugadzirwa - machubhu eSchoeller erudzi rweSierra anofukidza zvese zvinobvira. Dhizaini yemapaipi uye bvunzo dzemhando inoenderana dzinoita kuti mhinduro yekupedzisira ikwanise kumira kumanikidzwa kwemukati kusvika kumabhawa 2,500 pasina dambudziko. Pamusoro pezvo, zvinhu zvemhando yepamusoro, pamwe chete nehunhu hwepamusoro hwakavandudzwa hunobva mukudhirowa kwewaya, hazvipindi mumigumisiro yemvura yemunyu nezvimwe zvinopisa.
Chimwe chezvinhu zviri muchubhu iyi ndechekukombama kwayo kwakanyatsojeka uye kunaka kwayo kwekukwevera. Chaizvoizvo, zvinhu zvepasi hazvisi chinhu chakakosha, uye mapaipi ega ega anosvika 2,000 metres anogona kugadzirwa. Mapuragi emukati (mapulagi) anoshandiswa kukwevera mukati memarangi ehurefu. Pamwe chete nemarangi ekunze, chikamu chekutanga chechubhu chinogona kuderedzwa kusvika 50%. Zvose pamwe chete, iyi mhinduro yakakwevera hurefu inopa mufananidzo wechubhu isina musono. Kuona magadzirirwo echinhu ichi kwakaratidza kuti marangi aisanyatsoonekwa kunyangwe mushure mekunge paipi yakweverwa. Hunhu hwakadai ndihwo hunonyanya kukosha kune vatengi vekunze kweSchoeller Werk.
Indasitiri yekunze kwenyika inoshandisa mapaipi aya senzira dzekudzora mavharuvhu ekuchengetedza uye kupomba makemikari muzvirongo zvemafuta. Nenzira iyi, anotsigira maitiro ese ekuburitsa. Machubhu ekuisa jekiseni anobvumira vashandisi vema rig kunanga makemikari kuti anyungudike peturu, nokudaro zvichivandudza hunhu hwayo hwekuyerera. Mukuita kwakaoma kwekugadzira, mapaipi anoedzwa zvakasiyana-siyana asati aiswa kuti ave nechokwadi chekuti chigadzirwa chacho chakanaka. Mitsetse yesimbi inosungirirwa pamwe chete nematanda marefu uchishandisa nzira yekubatanidza tungsten inert gas (TIG) uye yobva yapinda mumachubhu. Pamusoro pekuyedzwa kwe eddy current, chubhu inozoedzwa nemhepo iri pasi pemvura (AUW kana "bubble"). Chubhu inonyudzwa mumvura uye inozadzwa nemhepo inosvika 210 bar. Ita ongororo yekuona nehurefu hwese hwemachubhu kuti uone kuti akavharwa. Kuti Schoeller Werk ikwanise kupa vatengi vayo hurefu hunodiwa hwe 15,000m zvichikwira, mapaipi ega ega anosungirirwa pamwe chete uye X-ray kuti aone kana ma weld e rail asina mhepo uye asina maburi emhepo.
Schoeller Werk inoitawo bvunzo dze hydraulic pamapombi ekudzora nekuisa jekiseni isati yaendeswa kumutengi. Izvi zvinosanganisira kuzadza coil yapera nemafuta e hydraulic uye kuiisa pasi pekumanikidzwa kunosvika 2,500 bar kuti ifananidze mamiriro akaipisisa anowanzo sangana nawo mumabasa ekunze kwegungwa.
Pamusoro pekugadzira mapaipi epurasitiki, Schoeller Werk inopawo vatengi vari muindasitiri yekunze kwenyika basa rakazara, semuenzaniso kuvharwa kwemapaipi nepurasitiki muzvikamu zvinonzi flat packs. Izvi zvinoreva kuti chubhu inogona kubatanidzwa nechubhu yekuburitsa uye kudzivirirwa kubva pakukombama nekudzvanywa. Mamwe mabasa anosanganisira kupukuta nekuzadza mapaipi. Pano, mukati mepaipi munosvinwa ne hydraulic fluid kusvika mvura yasvika padanho reISO kana SAE purity. Mvura inoseferwa nenzira iyi inogona kuramba iri mupaipi kana mutengi achida, zvichireva kuti mushandisi ane chigadzirwa chinogona kushandiswa. Pamusoro pezvo, chubhu dzinogona kunge dzakashongedzerwa newaya kana tambo dzesimbi dzisina tsvina. Pamusoro pezvo, nekuda kwenzvimbo yemukati yakapfava, chubhu ye plug-in yakakodzerawo kushandiswa senzira yekutumira tambo dze optical.
Schoeller Werk yakabatana nemusika wepasi rose mukushandira pamwe kwayo neindasitiri yekunze kwenyika. Pamusoro peNorway neUnited Kingdom pedyo neEuropean North Sea, Russia, Saudi Arabia, United Arab Emirates, Africa, Asia, Australia neSouth America ndedzimwe dzenzvimbo dzinonyanya kunangwa dzekushandisa Schoeller control lines nemapombi ekuisa mishonga yemakemikari.
