Chigadzirwa: Kaviri{{0}wall vacuum insulated tubing yehutsi, inorema-mafuta uye matsime egeothermal
Tembiricha: Kusvika 400 madhigirii sevhisi ine yakaderera k-kuvharidzira kukosha kuderedza kupisa kwemutsime
Material & Giredhi: API 5CT isina musono tubing mumakiredhi N80–Q125
Size Range: 2-7/8"×1.9" kusvika 7"×5-1/2", R2/R3, insulated pup majoini anowanikwa
Hunhu: Vacuum yega yega yemubatanidzwa-yakaedzwa, NDT + thermal yakaedzwa nezvitupa zvinorongeka zvizere
Chipfunga chega chega-jekiseni kana geothermal chirongwa chinopedza mari yakawanda kushandura mafuta kuti ive yakakwirira-yemhando yepamusoro. Mutambo yetubhing yakajairwa, chikamu chikuru chesimba iroro chinorasika munzira yekudzika: kunaka kweutsi kunodonha, mafuta anoramba akamira, wakisi uye chikero zvinovaka, ganda rinopisa uye, mupermafrost, pasi rakapoteredza tsime rinogona kutanga kunyunguduka. Kana vashandisi vasvika panguva ino, mubvunzo hausisiri "mutsindo wakawanda?" asi "tinochengeta sei kupisa kune zvakakosha?"
Octal Pipe'sinsulated tubing, inozivikanwawo sevacuum insulated tubing (VIT), rakagadzirirwa chaizvo matsime aya. Joint yega yega ine mbiri-madziro ekubatanidza ine chubhu yekugadzira mukati uye yekunze inotakura chubhu. Iyo annulus inozadzwa nepamusoro-kuvharisa uye inotakurwa kune yakakwira vacuum, ine inopenya layer uye getters kuvhara conduction, convection nemwaranzi panguva imwe chete. Zvichienzaniswa netubing isina chinhu, VIT tambo yedu inoburitsa yakakwira zvakanyanya pasi-paburi rehutsi, tembiricha yakaderera yeannulus uye kushomeka kwekupisa pamita.
Yakavakwa paAPI 5CT tubing mamakisi akaita seN80, L80 neP110 ine BTC kana premium gasi-makonesheni akasimba, Octalpre-insulated tubinginogona kushandiswa nemidziyo yekubata yeOCTG yakajairwa, asi inokupa kushanda kwekupisa kunodiwa pakurema-jekiseni rehutsi hwemafuta, kugadzirwa kwemafuta anorema kubva kumahombekombe-, matsime epermafrost uye mapurojekiti enthalpy geothermal akakwirira.
Iyo Octal Insulated Tubing Inoshanda
Octal insulated tubing inovakwa seakaviri{{0}wall concentric pipe tambo. Nhengo imwe neimwe ine dikichubhu yemukatiinotakura mvura yemutsime uye yakakurachubhu yekunzeinodzivirira ungano. Iwo machubhu maviri anosungirirwa pamwe chete kumativi ese maviri, achigadzira rakavharwaannular insulation nzvimbopakati pavo. Majoini akabatana mugomba neAPI BTC kana premium threaded couplings, saka tambo yakazara inomhanya seyakajairwa tubing.
Iyo yekupisa dhizaini yakavakirwa pakucheka zvesematatu akakosha ekupisa-nzira dzekufambisa - conduction, convection uye radiation - mu annulus:
- Aluminium foil yekuvharisa mwaranzi
Reflective aluminium foil yakaputirwa mu annulus kuratidza infrared radiation ichidzokera kune inopisa yemukati chubhu. Izvi zvinoderedza zvakanyanya kurasikirwa nekupenya kwekupisa pakupisa kwakanyanya kweutsi.
- Insulation zvinhu zve conduction control
Nzvimbo iri pakati pepombi yemukati nekunze yakazadzwa ne-conductivity insulation yakaderera (seperlite powder kana ultra{1}}fine glass wool). Izvi zvinowedzera kupisa kwekupisa kweannulus uye kunomisa conductive kupisa kuyerera.
- Vacuum uye getters kudzvinyirira convection
Mushure megungano, iyo annulus inoburitswa kune yakakwira vacuum uye yakashongedzerwa nemagita anoramba achitora magasi asara. Iine inenge isina gasi yasara kuti ifambe, convective heat transfer mu annulus inobviswa zvinobudirira.
- Pre-stress treatment yemukati mechubhu kuitira kuchengetedza
Pombi yemukati inopihwa yakadzorwa pre-stress isati yave kusonerera kwekupedzisira, kuitira kuti kuwedzera kwemafuta uye kudhonzwa panguva yewelding uye kushanda kwemunda kusakonzeresa kushungurudza kwasara. Izvi zvinobatsira kuchengetedza weld zone uye iyo yejoini yese yakachengeteka pamusoro peakawanda ekudziya uye kutonhora kutenderera.
Nekubatanidza iyi-pombi chimiro nekudzivirira mwaranzi, kuvharisa kwakasimba, vacuum yakakwirira uye mukati{{0}tube pre-kushushikana., Octal insulated tubing inoderedza kurasikirwa nekupisa padivi petsime ichiri kuita zvemagetsi seyakajairika OCTG tubing tambo.
Chinhu chakakosha cheinjiniya ndechekuti kuita kwekupisa hakutemerwe nekuisa zvinhu chete. Mubasa remumunda, kurasikirwa nekupisa kunokanganiswa zvakanyanya neannulus kugadzikana, kupera-weld integrity uye joint-area thermal control mushure mekudzokororwa tembiricha bhasikoro. Ndosaka pre{4}stressed insulated tubing ichinyanya kukosha mucyclic steam service kwete mukudzikama-tembiricha chete.

Kugadzira & Kuvimbiswa Kwemhando
Yedu insulated tubing yekugadzira nzira yakagadzirwa yakatenderedza kuvimbika kwevacuum annulus pamwe nekuita kwemakanika:

- Pre{{0}kutambanudza uye welding– controlled pre-stretch inoiswa kuchubhu yemukati, zvino mapeto ese ari welded kuvhara annulus uchichengetedza kurongeka.
- Vacuum processing- iyo annulus inobviswa kune yakatarwa vacuum level; getters inogadziriswa kuchengetedza yakaderera kudzvinyirira pamusoro pehupenyu hwetambo.
- Leak uye vacuum kuvimbika bvunzo- ma welds uye vacuum ports anoedzwa (NDT uye leak bvunzo) kuratidza annulus tightness.
- Thermal conductivity test- majoini emuenzaniso kubva kubhechi yega yega anoedzwa λ kuti aone giredhi rekudzivirira.
