Ukuze kuhlangatshezwane nezidingo ezihlukene zabasebenzisi nezisombululo, izinhlobo ezahlukene zokuhlanganisa/ukuxhumana zikhiqizwa ekwakhiweni kwepayipi le-vacuum insulated/jacket.
Ngaphambi kokuxoxa ngokuhlanganisa/ukuxhumana, kumele kuhlukaniswe izimo ezimbili,
1. Ukuphela kwesistimu yamapayipi e-vacuum insulated ixhunywe kwamanye amadivaysi, njengethangi lokugcina nezinto zokusebenza,
A. Weld Coupling
B. Flange Coupling
C. V-band Clamp Coupling
D. Bayonet Coupling
E. Ukuhlanganisa Okunentambo
2. Njengoba isistimu yamapayipi e-vacuum insulated inobude obude, ayikwazi ukukhiqizwa futhi ihanjiswe iyonke. Ngakho-ke, kukhona futhi ukuhlangana phakathi kwamapayipi e-vacuum insulated.
A. Ukuhlanganisa Okushiselwe (Ukugcwalisa I-Perlite Kumkhono Ongagqunyiwe)
B. I-Welded Coupling (Vacuum-out the Sleeve Insulated)
C. Vacuum Bayonet Coupling with Flanges
D. Vacuum Bayonet Coupling ne-V-band Clamp
Okuqukethwe okulandelayo kumayelana nokuhlangana kwesimo sesibili.
Uhlobo Lokuxhuma Olushiselwe
Uhlobo lokuxhuma esizeni lwe-Vacuum Insulated Pipes luxhumano olushiselwe. Ngemva kokuqinisekisa iphoyinti lokushisela nge-NDT, faka I-Insulation Sleeve bese ugcwalisa I-Sleeve nge-pearlite ukuze uthole ukwelashwa kwe-insulation. (I-Sleeve lapha singaphinda sicinywe, noma zombili zicociwe futhi zigcwaliswe nge-perlite. Ukubukeka komkhono kuzohluka kancane. Umkhono onconywa kakhulu ukuthi ugcwaliswe nge-perlite.)
Kunochungechunge lwemikhiqizo eminingana yohlobo lokuxhuma oluhlanganisiwe lwe-Vacuum Insulated Pipe. Eyodwa ifanele i-MAWP engaphansi kuka-16bar, enye isuka ku-16bar iye ku-40bar, enye isuka ku-40bar iye ku-64bar, kanti eyokugcina ingeye-liquid hydrogen ne-helium service (-270℃).
Vacuum Bayonet Connection Type With Flanges
Faka Ipayipi Lokunweba Lowesilisa Lwe-Vacuum Epayipini Lokunweba Lowesifazane futhi ulivikele nge-flange.
Kukhona uchungechunge lwemikhiqizo emithathu yohlobo lokuxhuma lwe-vacuum bayonet (ene-flange) ye-Vacuum Insulated Pipe. Eyodwa ifanele i-MAWP engaphansi kwe-8bar, eyodwa eye-MAWP engaphansi kwe-16bar, kanti eyokukugcina ingaphansi kwe-25bar.
Vacuum Bayonet Connection Uhlobo Nge-V-band Clamp
Faka Ipayipi Lokunweba Lowesilisa Lwe-Vacuum Epayipini Lokunweba Lowesifazane futhi ulivikele nge-v-band clamp. Lolu uhlobo lokufakwa ngokushesha, olusebenza ku-VI Piping enomfutho ophansi kanye nobubanzi bepayipi elincane.
Njengamanje, lolu hlobo lokuxhuma lungasetshenziswa kuphela uma i-MAWP ingaphansi kuka-8bar futhi ububanzi bepayipi elingaphakathi lingelikhulu kune-DN25 (1').
