Tuubooyinka Vacuum Insulated (VI Piping), oo ah Tuubbooyinka Jaakadaha Vacuum (Vacuum Jacketed Pipe) (Vacuum Piping), oo ah beddelka saxda ah ee dahaadhka tuubooyinka caadiga ah. Marka la barbar dhigo dahaarka tuubooyinka caadiga ah, qiimaha daadinta kulaylka ee VIP waa kaliya 0.05 ~ 0.035 jeer dahaarka tuubooyinka caadiga ah. Si weyn u badbaadi tamarta iyo kharashka macaamiisha.
Taxanaha wax soo saarka ee Tuubada Jaakadaha Vacuum, Vacuum Jacketed Hose, Vacuum Jacketed Valve, iyo Wajiga Kala-saar ee Shirkadda Qalabka Cryogenic ee HL, kaas oo soo maray taxane ah daaweyn farsamo oo aad u adag, ayaa loo isticmaalaa wareejinta oksijiinta dareeraha ah, nitrogen dareere ah, argon dareere ah, dareeraha hydrogen, helium dareere ah, LEG iyo LNG, iyo alaabtan waxaa loogu adeegaa qalabka cryogenic (tusaale, taangiyada cryogenic, dewars iyo coldboxes iwm) ee warshadaha kala soocida hawada, gaaska, duulista, elektarooniga, superconductor, chips, kulan otomaatig ah, cuntada & cabitaanka, farmashiyaha, isbitaalka, biobank, caag, wax cusub soo saarka kiimikada injineernimada, birta & birta, iyo cilmi-baarista sayniska iwm.
Saddexda Nooc ee Isku xidhka Tuubooyinka VI
Saddexda nooc ee isku xirka halkan waxay khuseeyaan oo keliya meelaha isku xirka ee u dhexeeya tuubooyinka VI. Marka VI Pipe ay ku xirto qalabka, haanta kaydinta iyo wixii la mid ah, isku xirka isku xirka waxaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha.
Si loo kordhiyo baahiyaha kala duwan ee macaamiisha, Vacuum Insulated Pipe waxay soo saartay saddex nooc oo isku xidha, oo kala ah Vacuum Bayone Connection Type with Clamps, Vacuum Bayone Connection Type with Flanges and Bolts and Welded Connection Type. Waxay leeyihiin faa'iidooyin kala duwan waxayna ku habboon yihiin xaalado shaqo oo kala duwan.
