Ukuze kuhlangatyezwane neemfuno ezahlukeneyo zabasebenzisi kunye nezisombululo, iintlobo ezahlukeneyo zokudibanisa/zoqhagamshelo zenziwa kuyilo lombhobho ogqunywe nge-vacuum insulation/jacketed.
Ngaphambi kokuba uxoxe ngokudibanisa/ukudibanisa, kukho iimeko ezimbini ekufuneka zahlulwe,
1. Isiphelo senkqubo yemibhobho egqunywe nge-vacuum siqhagamshelwe kwezinye izixhobo, ezifana netanki yokugcina kunye nezixhobo,
A. Ukudibanisa iWeld
B. Ukudibanisa iFlange
I-C. V-band Clamp Coupling
D. Ukudibanisa iBayonet
E. Ukudibanisa Ngemisonto
2. Njengoko inkqubo yemibhobho egqunywe nge-vacuum inobude obude, ayinakuveliswa kwaye ithuthwe iyonke. Ke ngoko, kukwakho nemibhobho edibeneyo phakathi kwemibhobho egqunywe nge-vacuum.
A. I-Welded Coupling (Ukuzalisa iPerlite kwiSleeve eVinjiweyo)
B. Isihlanganisi Esidityanisiweyo (Ukumpompa iVacuum kwiSleeve Esigqunyiweyo)
C. Ukudibanisa i-Vacuum Bayonet kunye neeFlanges
D. I-Vacuum Bayonet Coupling ene-V-band Clamps
Oku kulandelayo malunga nokudibanisa kwimeko yesibini.
Uhlobo loQhagamshelo oluWelding
Uhlobo loqhagamshelo lweVacuum Insulated Pipes kwindawo luqhagamshelo oludibeneyo. Emva kokuqinisekisa indawo yokuwelda nge-NDT, faka i-Insulation Sleeve uze ugcwalise i-Sleeve nge-pearlite ukuze kulungiswe ukugquma. (I-Sleeve apha ingagutyungelwa nge-vacuum, okanye zombini igutyungelwe nge-vacuum kwaye igcwaliswe nge-perlite. Inkangeleko ye-Sleeve iya kwahluka kancinci. I-Sleeve ecetyiswayo kakhulu izaliswe yi-perlite.)
Kukho uthotho lweemveliso ezahlukeneyo zohlobo loqhagamshelo oludibeneyo lwePipe efakwe iVacuum Insulated. Enye ifanelekile kwiMAWP engaphantsi kwe-16bar, enye isuka kwi-16bar ukuya kwi-40bar, enye isuka kwi-40bar ukuya kwi-64bar, kwaye eyokugqibela yeyolwelo lwe-hydrogen kunye ne-helium (-270℃).
Uhlobo loQhagamshelo lwe-Vacuum Bayonet oluneFlanges
Faka iVacuum Male Extension Pipe kwiVacuum Female Extension Pipe uze uyiqinise ngeflange.
Kukho uthotho lwemveliso ezintathu zohlobo loqhagamshelo lwe-vacuum bayonet (eneflange) ye-Vacuum Insulated Pipe. Enye ifanelekile kwi-MAWP engaphantsi kwe-8bar, enye ye-MAWP engaphantsi kwe-16bar, kwaye eyokugqibela ingaphantsi kwe-25bar.
Uhlobo loQhagamshelo lwe-Vacuum Bayonet olune-V-band Clamps
Faka iVacuum Male Extension Pipe kwiVacuum Female Extension Pipe uze uyiqinise nge-v-band clamp. Olu luhlobo lokufakelwa ngokukhawuleza, olusebenza kwiVI Piping enoxinzelelo oluphantsi kunye nobubanzi obuncinci bepayipi.
Okwangoku, olu hlobo loqhagamshelo lungasetyenziswa kuphela xa i-MAWP ingaphantsi kwe-8bar kwaye ububanzi bombhobho wangaphakathi bungekho ngaphezu kwe-DN25 (1').
