Vacuum Jacketed Pipe Series

Kufotokozera Kwachidule:

Vacuum Insulated Pipe (VI Piping), yomwe ndi Vacuum Jacketed Pipe (VJ Piping) imagwiritsidwa ntchito potumiza mpweya wamadzimadzi, nayitrogeni yamadzimadzi, argon yamadzimadzi, haidrojeni yamadzimadzi, helium yamadzi, LEG ndi LNG, monga choloweza m'malo mwabwino kwa kutchinjiriza kwa mapaipi.

Mutu: Kubweretsa Vacuum Jacketed Pipe Series


Tsatanetsatane wa Zamalonda

Zolemba Zamalonda

Kufotokozera Mwachidule:

  • Kutsekemera kwapamwamba kwa kayendedwe ka cryogenic fluid
  • Zosankha zomwe mungasinthire kuti zikwaniritse zofunikira za polojekiti
  • Zomangamanga zolimba komanso zapamwamba
  • Amapangidwa ndi fakitale yotsogola yomwe imayang'ana zaluso komanso kudalirika

Tsatanetsatane wa Zamalonda:

Superior Insulation for Cryogenic Fluid Transportation:
Gulu lathu la Vacuum Jacketed Pipe Series lidapangidwa kuti lizipereka chitetezo chapadera, kuwonetsetsa kuyenda koyenera komanso kotetezeka kwamadzimadzi a cryogenic. Mapangidwe a vacuum amachepetsa kutentha, kusunga kutentha kwa madzi mkati mwa mapaipi, ndi kuchepetsa chiopsezo cha kutentha kapena kusinthasintha kwa kutentha.

Zosankha Zomwe Mungasinthire Kuti Mukwaniritse Zofunikira Pama projekiti:
Timamvetsetsa kuti ma projekiti osiyanasiyana amatha kukhala ndi mawonekedwe apadera komanso zofunikira. Chifukwa chake, Vacuum Jacketed Pipe Series yathu imapereka zosankha zomwe mungasinthire, kuphatikiza makulidwe osiyanasiyana, makulidwe a insulation, ndi zosankha zakuthupi. Izi zimatsimikizira kuti mapaipi amatha kukonzedwa kuti akwaniritse zosowa zenizeni za polojekiti iliyonse, kupereka ntchito yabwino komanso yogwira ntchito.

Zomanga Zolimba Komanso Zapamwamba:
Zopangidwa ndi zida zolimba komanso zapamwamba kwambiri, mapaipi athu okhala ndi vacuum amapangidwa kuti athe kupirira zovuta zamafakitale. Kumanga kolimba kumatsimikizira moyo wautali komanso kudalirika, ngakhale m'malo ovuta, kuwapangitsa kukhala odalirika pamayendedwe amadzimadzi a cryogenic.

Opangidwa ndi Factory Yotsogola Yoyang'ana Zatsopano ndi Kudalirika:
Monga fakitale yotsogola yopangira zinthu, tadzipereka kupereka zinthu zamafakitale zapamwamba kwambiri komanso zatsopano. Gulu lathu la Vacuum Jacketed Pipe Series ndi umboni wakudzipereka kwathu pakuchita bwino kwambiri, uinjiniya wolondola, komanso njira zowongolera zowongolera, kuwonetsetsa kuti makasitomala athu alandila chinthu chapamwamba kwambiri.

Pomaliza, gulu lathu la Vacuum Jacketed Pipe Series limapereka kutchinjiriza kwapamwamba pamayendedwe amadzimadzi a cryogenic, zosankha makonda kuti zikwaniritse zofunikira za projekiti, komanso zomangamanga zolimba, zapamwamba. Ndi kudzipereka kwathu pazatsopano komanso kudalirika, tili ndi chidaliro kuti mapaipi athu okhala ndi vacuum adzapereka mayankho ogwira mtima komanso odalirika pazosowa zosiyanasiyana zamayendedwe amadzimadzi a cryogenic.

Vacuum Insulated Piping

Vacuum Insulated Pipe (VI Piping), yomwe ndi Vacuum Jacketed Pipe (VJ Piping), monga choloweza m'malo mwabwino chotsekereza mapaipi wamba. Poyerekeza ndi kutchinjiriza kwa mapaipi wamba, kutsika kwa kutentha kwa VIP kumangokhala nthawi 0.05 ~ 0.035 za kutsekereza mapaipi wamba. Sungani kwambiri mphamvu ndi mtengo kwa makasitomala.

Mndandanda wazinthu za Vacuum Jacketed Pipe, Vacuum Jacketed Hose, Vacuum Jacketed Valve, ndi Phase Separator mu HL Cryogenic Equipment Company, yomwe idadutsa njira zingapo zamankhwala okhwima kwambiri, imagwiritsidwa ntchito posamutsa mpweya wamadzimadzi, nayitrogeni yamadzimadzi, argon yamadzimadzi, madzi wa hydrogen, helium yamadzi, LEG ndi LNG, ndipo zinthu izi zimagwiritsidwa ntchito pazida za cryogenic (mwachitsanzo, akasinja a cryogenic, dewars ndi coldboxes etc.) m'mafakitale olekanitsa mpweya, mpweya, ndege, zamagetsi, superconductor, tchipisi, msonkhano wodzichitira, chakudya & chakumwa, mankhwala, chipatala, biobank, mphira, zinthu zatsopano kupanga mankhwala uinjiniya, chitsulo & zitsulo, ndi kafukufuku sayansi etc.

Mitundu itatu yolumikizira ya VI Piping

Mitundu itatu yolumikizira pano imagwira ntchito pazolumikizana pakati pa mapaipi a VI. Pamene VI Pipe ikugwirizanitsa ndi zipangizo, thanki yosungirako ndi zina zotero, cholumikizira cholumikizira chikhoza kusinthidwa malinga ndi zofuna za makasitomala.

Pofuna kukulitsa zosowa zosiyanasiyana za makasitomala, Vacuum Insulated Pipe yapanga mitundu itatu yolumikizira, yomwe ndi Vuta la Bayonet Connection Type with Clamp, Vacuum Bayonet Connection Type yokhala ndi Flanges ndi Bolts ndi Welded Connection Type. Iwo ali ndi ubwino wosiyana ndipo ndi oyenera ntchito zosiyanasiyana.
