Cov Kav Dej Nqus Tsev Uas Muaj Cov Khoom Siv Rwb Thaiv Tsev
Cov Yeeb Nkab Nqus Tsev (VI Piping), uas yog Cov Yeeb Nkab Nqus Tsev (VJ Piping), yog ib qho kev hloov pauv zoo tshaj plaws rau cov yeeb nkab rwb thaiv tsev ib txwm muaj. Piv nrog cov yeeb nkab rwb thaiv tsev ib txwm muaj, tus nqi cua sov xau ntawm VIP tsuas yog 0.05 ~ 0.035 npaug ntawm cov yeeb nkab rwb thaiv tsev ib txwm muaj. Txuag hluav taws xob thiab nqi rau cov neeg siv khoom.
Cov khoom lag luam ntawm Cov Yeeb Nkab Nqus Tsev, Cov Yeeb Nkab Nqus Tsev, Lub Qhov Dej Nqus Tsev, thiab Lub Tshuab Sib Cais Theem hauv HL Cryogenic Equipment Company, uas tau dhau los ntawm ntau yam kev kho mob nruj heev, yog siv rau kev hloov cov pa oxygen, nitrogen, argon, hydrogen, helium, LEG thiab LNG, thiab cov khoom no yog cov khoom siv rau cov khoom siv cryogenic (piv txwv li cov tank cryogenic, dewars thiab coldboxes thiab lwm yam) hauv kev lag luam ntawm kev sib cais huab cua, roj, aviation, electronics, superconductor, chips, automation assembly, khoom noj & dej haus, tshuaj, tsev kho mob, biobank, roj hmab, cov khoom siv tshiab tsim tshuaj engineering, hlau & hlau, thiab kev tshawb fawb thiab lwm yam.
Peb Hom Kev Sib Txuas ntawm VI Piping
Peb hom kev sib txuas no tsuas yog siv rau qhov chaw sib txuas ntawm cov kav dej VI xwb. Thaum cov kav dej VI txuas nrog cov khoom siv, lub tank cia khoom thiab lwm yam, qhov sib txuas tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Yuav kom ua tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv, Cov Yeeb Nkab Nqus Tsev Insulated tau tsim peb hom kev sib txuas, uas yog Hom Kev Sib Txuas Nqus Tsev Bayonet nrog Clamps, Hom Kev Sib Txuas Nqus Tsev Bayonet nrog Flanges thiab Bolts thiab Hom Kev Sib Txuas Welded. Lawv muaj ntau yam zoo thiab haum rau ntau yam kev ua haujlwm sib txawv.
