Pofuna kukwaniritsa zosowa ndi mayankho osiyanasiyana a ogwiritsa ntchito, mitundu yosiyanasiyana yolumikizira/yolumikizira imapangidwa popanga chitoliro chotetezedwa ndi vacuum/chokhala ndi jekete.
Musanakambirane za kulumikizana/kulumikizana, pali zinthu ziwiri zomwe ziyenera kusiyanitsa,
1. Mapeto a makina opopera mapaipi otetezedwa ndi vacuum amalumikizidwa ndi zipangizo zina, monga thanki yosungiramo zinthu ndi zida,
A. Kulumikiza kwa Weld
B. Kulumikiza kwa Flange
C. V-band Clamp Coupling
D. Cholumikizira cha Bayonet
E. Kulumikiza Ulusi
2. Popeza makina opopera mapaipi otetezedwa ndi vacuum ali ndi kutalika kwakutali, sangathe kupangidwa ndikunyamulidwa yonse. Chifukwa chake, palinso zolumikizira pakati pa mapaipi otetezedwa ndi vacuum.
A. Cholumikizira Cholumikizidwa (Kudzaza Perlite mu Chikwama Chotetezedwa)
B. Cholumikizira Cholumikizidwa (Chotulutsa Vacuum Sleeve Yotetezedwa)
C. Cholumikizira cha Vacuum Bayonet ndi Flanges
D. Cholumikizira cha Vacuum Bayonet ndi Ma Clamp a V-band
Nkhani zotsatirazi zikunena za ma couplings mu mkhalidwe wachiwiri.
Mtundu Wolumikizira Wowotcherera
Mtundu wolumikizira wa Mapaipi Otetezedwa ndi Vacuum pamalopo ndi wolumikizidwa. Mukatsimikizira malo owetera ndi NDT, ikani Insulation Sleeve ndikudzaza Sleeve ndi pearlite kuti muchepetse kutentha. (Sleeve pano ikhozanso kutsukidwa, kapena kutsukidwa ndi vacuum ndikudzazidwa ndi perlite. Mawonekedwe a Sleeve adzakhala osiyana pang'ono. Sleeve yolimbikitsidwa kwambiri yodzazidwa ndi perlite.)
Pali zinthu zingapo zomwe zimagwiritsidwa ntchito polumikiza mapaipi otetezedwa ndi Vacuum. Chimodzi ndi choyenera MAWP pansi pa 16bar, chimodzi kuyambira 16bar mpaka 40bar, chimodzi kuyambira 40bar mpaka 64bar, ndipo chomaliza ndi cha madzi a hydrogen ndi helium service (-270℃).
Mtundu Wolumikizira wa Vacuum Bayonet Ndi Flanges
Ikani Chitoliro Chowonjezera cha Male Vacuum mu Chitoliro Chowonjezera cha Male Vacuum ndikuchimangirira ndi flange.
Pali mitundu itatu ya zinthu zomwe zimagwiritsidwa ntchito polumikizira chitoliro cha vacuum bayonet (chokhala ndi flange) cha Vacuum Insulated Pipe. Chimodzi ndi choyenera MAWP pansi pa 8bar, chimodzi ndi cha MAWP pansi pa 16bar, ndipo chomaliza chili pansi pa 25bar.
Mtundu Wolumikizira wa Vacuum Bayonet Ndi Ma Clamp a V-band
Ikani Chitoliro cha Male Extension cha Vacuum mu Chitoliro cha Male Extension cha Vacuum ndikuchimangirira ndi chomangira cha v-band. Uwu ndi mtundu wa kukhazikitsa mwachangu, komwe kumagwiritsidwa ntchito pa VI Piping yokhala ndi mphamvu yochepa komanso mainchesi ang'onoang'ono a chitoliro.
Pakadali pano, mtundu uwu wolumikizira ungagwiritsidwe ntchito pokhapokha ngati MAWP ili yochepera 8bar ndipo m'mimba mwake wa chitoliro chamkati sichili chachikulu kuposa DN25 (1').
