Ụdị Njikọ Welded
Ụdị njikọ dị na saịtị nke Vacuum Insulated Pipes bụ njikọ welded. Mgbe NDT kwadoro ebe weld ahụ, wụnye mkpuchi mkpuchi ma jupụta Sleeve na pearlite maka ọgwụgwọ mkpuchi. (The Sleeve ebe a nwekwara ike vacuumed, ma ọ bụ abụọ vacuumed na jupụta perlite. Ọdịdị nke uwe ga-adịtụ iche. tumadi na-atụ aro Sleeve jupụtara perlite.)
Enwere ọtụtụ usoro ngwaahịa maka ụdị njikọ nke Vacuum Insulated Pipe. Otu dabara maka MAWP n'okpuru 16bar, otu sitere na 16bar ruo 40bar, otu sitere na 40bar ruo 64bar, nke ikpeazụ bụ maka ọrụ hydrogen mmiri mmiri na helium (-270 ℃).
Ụdị Njikọ Vacuum Bayonet na Flanges
Fanye ọkpọkọ ndọtị nwoke na-agụ Vacuum n'ime ọkpọkọ mgbatị nwanyị Vacuum ma jiri flange chekwaa ya.
Enwere usoro ngwaahịa atọ maka ụdị njikọ ikuku bayoneeti (ya na flange) nke Vacuum Insulated Pipe. Otu dabara maka MAWP n'okpuru 8bar, otu bụ maka MAWP n'okpuru 16bar, na nke ikpeazụ dị n'okpuru 25bar.
Ụdị Njikọ Vacuum Bayonet na V-band Clamps
Fanye ọkpọkọ ndọtị Vacuum nwoke n'ime ọkpọkọ mgbatị nwanyị Vacuum ma jiri mkpọ v-band chekwaa ya. Nke a bụ ụdị ntinye ngwa ngwa, ọdabara na VI Piping na obere nrụgide na obere ọkpọkọ ọkpọkọ.
Ugbu a, ụdị njikọ a nwere ike iji naanị mgbe MAWP na-erughị 8bar na dayameta ọkpọkọ dị n'ime adịghị ibu karịa DN25 (1').
