Kwa mafakitale omwe akugwira LNG, mpweya wamadzimadzi, kapena nayitrogeni,Vacuum Insulated Pipe (VIP)sikungosankha chabe—kaŵirikaŵiri ndiyo njira yokhayo yotsimikizirira zoyendera zosungika bwino. Pophatikiza chitoliro chonyamulira chamkati ndi jekete yakunja yokhala ndi vacuum yayikulu pakati,Vacuum Insulated Pipe (VIP)machitidwe amadula kwambiri ingress ya kutentha. Koma m'malo ngati malo opangira mafuta a m'mphepete mwa nyanja, malo okhala ndi mphepo yamkuntho, kapena malo oyeretsera m'chipululu, ngakhale opangidwa bwino.Vacuum Insulated Pipe (VIP)imayang'anizana ndi ziwopsezo zomwe zingafupikitse moyo wake.
Chiphunzitso cha kukhazikitsaVacuum Insulated Pipe (VIP)ndi yosavuta. Zoonadi? Osati kwambiri.
M'madera apansi a zero, chitsulo chikhoza kuchita mosiyana-kukhala chochepa kwambiri komanso chosavuta kusweka ngati sichiyendetsedwa bwino. Pazida za m'mphepete mwa nyanja, oyikapo nthawi zambiri amalimbana ndi dzimbiri chitoliro chisanayambe kugwira ntchito, chifukwa cha mpweya wodzaza ndi mchere. Ndipo m'madera otentha kwambiri m'chipululu, kutentha kwakukulu kwa usana ndi usiku kungayambitse kuwonjezereka komwe kumapangitsa kuti ma welds asokonezeke ndi zisindikizo za vacuum. Mainjiniya ambiri odziwa zambiri tsopano amatchula ma alloys osagwirizana ndi dzimbiri, opangidwa kaleVacuum Insulated Pipe (VIP)zigawo, ndi zosinthika zowonjezera zowonjezera kuti zithetse mavutowa asanayambe dontho loyamba la cryogenic.
A kunyalanyazidwaVacuum Insulated Pipe (VIP)imatha kuchoka pakuchita bwino kwambiri mpaka kukhetsa mphamvu mwachangu kuposa momwe ogwiritsa ntchito amayembekezera. Kuphwanyidwa pang'ono kwa vacuum layer kungayambitse chisanu, zomwe zimapangitsa kuti chithupsa chiwonjezeke komanso kukwera mtengo kwa ntchito. M'malo ovuta, mavutowa nthawi zambiri amabwera limodzi ndi kulowerera kwa fumbi, kuwonongeka kwamadzi am'madzi, kapena kutopa limodzi. Ogwira ntchito odalirika amagwiritsa ntchito kuphatikiza:
●Mayeso a kotala opanda vacuum m'malo mofufuza pachaka.
●Kafukufuku wa kujambula kwa kutentha kuti azindikire malo ozizira msanga.
● Zopaka zapamadzi ndi chitetezo cha cathodic pamapaipi akunyanja.
● Malo otchinga otsekera m’malo a m’chipululu kuti pasakhale fumbi lopsa.
Vacuum Insulated Pipe (VIP)akadali muyeso wa golide wa zoyendera za cryogenic m'malo ovuta - koma magwiridwe ake satsimikiziridwa ndi mapangidwe okha. Kuchokera pakusankhidwa kwa ma alloys mpaka kusankha kwanthawi zoyendera, kupambana kumabwera pakuwoneratu zam'tsogolo komanso kuwongolera. Mwachidule: kuchitira aVacuum Insulated Pipe (VIP)dongosolo ngati chuma chamtengo wapatali, ndipo idzagwira ntchito modalirika - kaya ndi mphepo yamkuntho ya Arctic kapena kuwotcha pansi padzuwa lachipululu.
