Mu rwego rwo kugabanya ibyuka bihumanya ikirere, isi yose irashaka ingufu zisukuye zishobora gusimbuza ingufu za peteroli, kandi LNG (Liquefied Natural Gas) nimwe mu guhitamo kwingenzi.HL yatangije umuyoboro wa Vacuum (VIP) no gushyigikira sisitemu yo kugenzura Vacuum Valve yo kohereza LNG kugirango ishobore isoko.
VIP yakoreshejwe cyane mumishinga ya LNG.Ugereranije no gukwirakwiza imiyoboro isanzwe, agaciro k'ubushyuhe bwa VIP ni inshuro 0.05 ~ 0.035 inshuro zisanzwe.
Ibikoresho bya HL Cryogenic bifite uburambe bwimyaka 10 mumishinga ya LNG.Umuyoboro wa Vacuum (VIP) wubatswe kuri ASME B31.3 Kode ya Piping kode nkibisanzwe.Uburambe bwubuhanga hamwe nubushobozi bwo kugenzura ubuziranenge kugirango hamenyekane neza nigiciro-cyiza cyuruganda rwabakiriya.
Ibicuruzwa bifitanye isano
Urukurikirane rwa Vacuum
Vacuum Yashizwemo Urutonde rworoshye
Ibikoresho bifasha sisitemu
ABAKUNZI BAMAZE
Gira uruhare mu kuzamura ingufu zisukuye.Kugeza ubu, HL yagize uruhare mu iyubakwa rya sitasiyo zirenga 100 n’inganda zirenga 10.

UMUTI
Ibikoresho bya HL Cryogenic biha abakiriya sisitemu yo gukwirakwiza imiyoboro ya Vacuum yujuje ibisabwa n'imishinga ya LNG:
1.Uburyo bwiza bwo gucunga neza: ASME B31.3 Kode y'ingutu.
2. Intera ndende yoherejwe: Ibisabwa byinshi byubushobozi bwa vacuum kugirango ugabanye igihombo cya gaze.
3.Intambwe ndende yo gutanga: birakenewe gutekereza kugabanuka no kwaguka k'umuyoboro w'imbere n'umuyoboro w'inyuma mumazi ya kirogenike no munsi yizuba.
4.Umutekano:
5.Guhuza na sisitemu ya pompe: Umuvuduko mwinshi wo gushushanya ni 6.4Mpa (64bar), kandi ukeneye indishyi ifite imiterere ihamye nubushobozi bukomeye bwo kwihanganira umuvuduko mwinshi.
6.Uburyo butandukanye bwo guhuza: Vacuum Bayonet Ihuza, Vacuum Socket Flange Ihuza hamwe na Welded Connection irashobora gutoranywa.Kubwimpamvu z'umutekano, Ihuza rya Vacuum Bayonet hamwe na Vacuum Socket Flange Ihuza ntabwo byemewe gukoreshwa mumuyoboro ufite diameter nini n'umuvuduko mwinshi.
7.Urutonde rwa Vacuum Yashizwe Kumurongo (VIV) Urutonde Ruraboneka: Harimo Vacuum Yashizwemo (Pneumatike) Gufunga-Valve, Vacuum Yagenzuwe Kugenzura Valve, Vacuum Yateganijwe Kugenzura Valve nibindi. Ubwoko butandukanye bwa VIV burashobora guhinduka muburyo bwo kugenzura VIP nkuko bisabwa.
