Ukuze kuhlangatshezwane nezidingo nezixazululo ezahlukene zomsebenzisi, kukhiqizwa izinhlobo ezahlukene zokuxhumanisa/ukuxhumanisa ekwakhiweni kwepayipi elifakwe i-vacuum insulation/jacketed.
Ngaphambi kokuxoxa ngokuxhumanisa/ukuxhumana, kunezimo ezimbili okumele zihlukaniswe,
1. Isiphelo sesistimu yamapayipi afakwe i-vacuum sixhunywe kwamanye amadivayisi, njengethangi lokugcina kanye nemishini,
A. Ukuxhumanisa Okushisiwe
B. Ukuxhumanisa iFlange
Ukuxhumanisa I-C. V-band Clamp
D. Ukuxhumanisa i-Bayonet
E. Ukuxhumanisa Okunezintambo
2. Njengoba uhlelo lwamapayipi olufakwe i-vacuum covering lunobude obude, alukwazi ukukhiqizwa nokuthuthwa lonke. Ngakho-ke, kukhona nokuhlanganiswa phakathi kwamapayipi afakwe i-vacuum covering.
A. Ukuxhuma Okuhlanganisiwe (Ukugcwalisa i-Perlite Esleeve Esivikelwe Ngomoya)
B. Ukuxhuma Okuhlanganisiwe (Ukupompa i-Vacuum Sleeve)
C. Ukuxhumanisa i-Vacuum Bayonet nama-Flanges
D. I-Vacuum Bayonet Coupling ene-V-band Clamps
Okuqukethwe okulandelayo kumayelana nokuhlanganiswa esimweni sesibili.
Uhlobo Lokuxhumeka Oluhlanganisiwe
Uhlobo lokuxhumanisa olusendaweni lwamapayipi afakwe i-Vacuum Insulated luxhunywa nge-weld. Ngemva kokuqinisekisa iphuzu lokushisela nge-NDT, faka i-Insulation Sleeve bese ugcwalisa i-Sleeve nge-pearlite ukuze kulungiswe ukushisela. (I-Sleeve lapha ingashiswa nge-vacuum, noma kokubili ishiswe nge-vacuum futhi igcwaliswe nge-perlite. Ukubukeka kwe-Sleeve kuzohluka kancane. I-Sleeve enconyiwe kakhulu igcwaliswe nge-perlite.)
Kunezinhlobo eziningana zochungechunge lwemikhiqizo yohlobo loxhumano oluhlanganisiwe lwepayipi elifakwe i-Vacuum Insulated. Elinye lifanelekela i-MAWP ngaphansi kwe-16bar, elinye lisukela ku-16bar kuya ku-40bar, elinye lisukela ku-40bar kuya ku-64bar, kanti elokugcina lingelasevisi ye-hydrogen ne-helium (-270℃).
Uhlobo Lokuxhumanisa lwe-Vacuum Bayonet Nama-Flanges
Faka i-Vacuum Male Extension Pipe ku-Vacuum Female Extension Pipe bese uyibopha nge-flange.
Kunezinhlobo ezintathu zochungechunge lwemikhiqizo yohlobo lokuxhuma i-vacuum bayonet (ene-flange) ye-Vacuum Insulated Pipe. Eyodwa ifanele i-MAWP engaphansi kwe-8bar, enye ifanele i-MAWP engaphansi kwe-16bar, kanti eyokugcina ingaphansi kwe-25bar.
Uhlobo Lokuxhumanisa lwe-Vacuum Bayonet Olunezibambo ze-V-band
Faka i-Vacuum Male Extension Pipe ku-Vacuum Female Extension Pipe bese uyibopha nge-v-band clamp. Lolu uhlobo lokufakwa okusheshayo, olusebenza kuma-VI Piping anomfutho ophansi kanye nobubanzi obuncane bepayipi.
Njengamanje, lolu hlobo lokuxhumana lungasetshenziswa kuphela uma i-MAWP ingaphansi kwe-8bar futhi ububanzi bepayipi langaphakathi bungebukhulu kune-DN25 (1').
