Kufananiza Mitundu Yosiyanasiyana Yophatikizana kwa Vacuum Insulated Pipe

Pofuna kukwaniritsa zosowa ndi mayankho osiyanasiyana, mitundu yosiyanasiyana yolumikizirana / yolumikizira imapangidwa popanga vacuum insulated / jekete chitoliro.

Musanayambe kukambirana za kulumikizana / kulumikizana, pali zinthu ziwiri zomwe ziyenera kusiyanitsa,

1. Mapeto a vacuum insulated mapaipi amalumikizidwa ndi zida zina, monga thanki yosungira ndi zida,

A. Weld Coupling

B. Kulumikizana kwa Flange

C. V-band Clamp Coupling

D. Bayonet Coupling

E. Kulumikizana kwa Ulusi

2. Popeza kuti vacuum insulated mapaipi ali ndi utali wautali, sangathe kupangidwa ndi kunyamulidwa lonse. Choncho, palinso malumikizanidwe pakati vacuum insulated mapaipi.

A. Welded Coupling (Kudzaza Perlite mu Insulated Sleeve)

B. Kulumikizitsa (Vacuum pump-out the Insulated Sleeve)

C. Vacuum Bayonet Kuphatikiza ndi Flanges

D. Vacuum Bayonet Coupling ndi V-band Clamp

Zomwe zili m'munsizi ndizokhudza kulumikizana kwachiwiri.

Mtundu Wolumikizira Welded

Mitundu yolumikizira patsamba la Vacuum Insulated Pipes ndi yolumikizidwa ndi welded. Pambuyo potsimikizira mfundo yowotcherera ndi NDT, yikani Sleeve ya Insulation ndikudzaza Sleeve ndi pearlite kuti muthandizidwe. (Sleeve apa ikhozanso kutsukidwa, kapena kutsekedwa ndi kudzazidwa ndi perlite. Maonekedwe a Sleeve adzakhala osiyana pang'ono. Sleeve yovomerezeka kwambiri yodzazidwa ndi perlite.)

Pali zinthu zingapo zopangira zolumikizira zamtundu wa Vacuum Insulated Pipe. Imodzi ndiyoyenera MAWP pansi pa 16bar, imodzi imachokera ku 16bar kupita ku 40bar, imodzi ikuchokera ku 40bar kupita ku 64bar, ndipo yomaliza ndi yamadzimadzi a hydrogen ndi helium (-270 ℃).

Mtundu Wolumikizira Bayonet Ndi Ma Flanges

Lowetsani Chitoliro Chowonjezera Chachimuna mu Vacuum Female Extension Pipe ndikuchiteteza ndi flange.

Pali zinthu zitatu zamtundu wa vacuum bayonet yolumikizira (yokhala ndi flange) ya Vacuum Insulated Pipe. Imodzi ndiyoyenera MAWP pansipa 8bar, imodzi ndi ya MAWP pansipa 16bar, ndipo yomaliza ili pansi pa 25bar.

Mtundu Wolumikizira Bayonet Ndi V-band Clamp

Lowetsani Chitoliro Chowonjezera cha Vacuum Male mu Vacuum Female Extension Pipe ndikuchiteteza ndi v-band clamp. Uwu ndi mtundu wa unsembe wofulumira, womwe umagwiritsidwa ntchito ku VI Piping yokhala ndi kuthamanga kochepa komanso m'mimba mwake yaing'ono.

Pakalipano, mtundu wolumikizira uwu ungagwiritsidwe ntchito pokhapokha MAWP ili yochepa kuposa 8bar ndipo m'mimba mwake ya chitoliro chamkati sichikulirapo kuposa DN25 (1').
