Ividiyo
Vacuum Insulated Piping
Umbhobho weVacuum Insulated (VIPiping), obizwa ngokuba nguMbhobho weJacket yeVacuum (VJ Piping), njengoMbhobho oGqibeleleyo wokugquma kwemibhobho eqhelekileyo. Xa kuthelekiswa nokugqunyelelwa kwemibhobho eqhelekileyo, ixabiso lokuvuza kobushushu le-VIP liyi-0.05 ~ 0.035 kuphela ngamaxesha okufakwa kwemibhobho eqhelekileyo. Ukugcina ngokubalulekileyo amandla kunye neendleko kubathengi.
Uluhlu lwemveliso ye-Vacuum Jacketed Pipe, i-Vacuum Jacketed Hose, iVacuum Jacketed Valve, kunye neSigaba Sokwahlula kwi-HL Cryogenic Equipment Company, edlula uluhlu lwezonyango ezingqongqo kakhulu, zisetyenziselwa ukuhanjiswa kwe-oksijini yolwelo, i-nitrogen engamanzi, i-argon yolwelo, i-hydrogen engamanzi, i-helium yolwelo, i-LEG kunye ne-LNG, kwaye ezi mveliso zisetyenziselwa izixhobo ze-cryogenic (umzekelo, amatanki e-cryogenic, i-dewars kunye neebhokisi ezibandayo njl. isiselo, ikhemesti, isibhedlele, i-biobank, irabha, izinto ezintsha zokwenza ubunjineli bemichiza, intsimbi kunye nentsimbi, kunye nophando lwezenzululwazi njl.
Iintlobo ezintathu zoQhagamshelwano lwe-VI Piping
Iindidi ezintathu zokudibanisa apha zisebenza kuphela kwiindawo zokuxhuma phakathi kwemibhobho ye-VI. Xa i-VI Pipe idibanisa nezixhobo, itanki yokugcina kunye nokunye, ukudibanisa ukudibanisa kunokwenziwa ngokwezifiso ngokweemfuno zabathengi.
Ukuze kwandiswe iimfuno ezahlukeneyo zabathengi, iVacuum Insulated Pipe iphuhlise iindidi ezintathu zoqhagamshelwano, ezizezi, iVacuum Bayonet Connection Type eneClamps, Vacuum Bayonet Connection Type with Flanges and Bolts and Welded Connection Type. Zineenzuzo ezahlukeneyo kwaye zifanelekile kwiimeko ezahlukeneyo zokusebenza.
