Lub Tshuab Nqus Tsev Ronsulated Piping
Lub tshuab nqus tsev insulated (vi piping), uas yog lub tshuab nqus tsev jackinged yeeb (vj piping), raws li ib qho zoo tshaj plaws hloov chaw rau cov piping piping rwb thaiv tsev. Piv nrog cov piping cov piping rwb thaiv tsev, cov cua sov kom tus nqi ntawm VIP tsuas yog 0.035 zaug ntawm cov piping piping rwb thaiv tsev. Tseem txuag txuag lub zog thiab tus nqi rau cov neeg siv khoom.
Cov khoom series ntawm lub tshuab nqus tsev Jose, lub tshuab ua kom zoo nkauj, yog siv rau kev hloov ua kua, ua kua nitrogen, kua argon, kua hydrogen, cov kua rau hauv caug, ceg thiab cov khoom lag luam, cov khoom siv hluav taws xob, cov tshuab raj, khoom siv hluav taws xob, khoom noj khoom haus & dej, tsev muag tshuaj, tsev kho mob, roj hmab, khoom siv tshiab tsim tshuaj engineering, Hlau & Science etc.
Peb hom kev sib txuas ntawm VI PIPING
Qhov peb txuas txuas ntawm no tsuas yog siv rau cov haujlwm sib txuas ntawm VI kav. Thaum VI yeeb nkab txuas nrog cov cuab yeej siv, ntim tank thiab lwm yam tuaj yeem kho tau raws li cov neeg siv khoom.
Txhawm rau kom ua kom tiav cov kev xav tau ntawm cov neeg siv khoom sib txawv, lub tshuab nqus tsev insulated tau tsim peb hom kev sib txuas, lub tshuab nqus tsev bayoning thiab bolts thiab welded txuas hom. Lawv nyias muaj qhov zoo sib txawv thiab tsim nyog rau cov haujlwm sib txawv.
