JDG cev
Paub tias yog lub tes tsho nruj teeb galvanized steel conduit, yog ib qho kev tiv thaiv rau hluav taws xob circuits. Nws siv cov ntsia hlau nruj kev sib txuas thev naus laus zis los tsim cov xaim xaim, tsis tas yuav tsum muaj kev sib txuas hauv av, vuam, thiab kev ua haujlwm threading, thiab nws cov tsos feem ntau yog nyiaj dawb lossis daj. Cov yam ntxwv ntawm cov kav dej JDG suav nrog lawv lub teeb yuag, tus nqi pheej yig, kev teeb tsa yooj yim, thiab zoo corrosion kuj thiab hluav taws kub. Tsis tas li ntawd, JDG cov kav dej kuj tseem muaj cov dej tsis zoo thiab cov dej tsis zoo, uas tuaj yeem ua kom ntev kev pab cuam lub neej ntawm cov xov hlau.
Hais txog lub ntsiab lus ntawm JDG yeeb nkab DN20, DN sawv cev rau lub nominal txoj kab uas hla, thiab DN20 sawv cev rau lub nominal txoj kab uas hla ntawm JDG yeeb nkab li 20 hli. DN20 JDG yeeb nkab haum rau ntau yam kev siv hluav taws xob tiv thaiv hluav taws xob, suav nrog cov xaim thiab cable tso rau hauv cov tsev lag luam, cov tsev ua haujlwm, khw muag khoom, tsev so, thiab lwm qhov chaw.
Qhov sib txawv tseem ceeb ntawm JDG tube thiab SC tube nyob hauv nws txoj kev sib txuas thiab cov khoom siv. SC kav (piv txwv li welded steel kav) feem ntau yog txuas nrog vuam, thaum JDG kav siv ntsia hlau zawm kev sib txuas tshuab. Tsis tas li ntawd, JDG cov kav dej siv cov kab txuas hauv av uas ua los ntawm cov kav hlau galvanized thiab nyias-walled steel kav, kov yeej qhov tsis zoo ntawm kev tsim kho thiab kev tsim kho siab ntawm cov hlau txuas. Nyob rau tib lub sijhawm, nws kuj daws cov teeb meem ntawm cov hluav taws tsis zoo thiab kev nyuaj hauv av ntawm cov kav dej PVC.
Qhov sib txawv tseem ceeb ntawm KBG kav thiab JDG kav yog nyob rau hauv lawv txoj kev sib txuas thiab cov yeeb nkab phab ntsa tuab. Cov yeeb nkab KBG txais kev sib txuas hom kev sib txuas, thaum JDG yeeb nkab txais kev sib txuas nruj. Cov phab ntsa tuab ntawm KBG kav dej muaj feem xyuam rau lawv qhov loj, thaum tus qauv phab ntsa thickness ntawm JDG kav yog tsim rau pre embedded nteg thiab suspended qab nthab nteg, thaum lub zoo tib yam hom tsuas yog haum rau suspended qab nthab nteg.
JDG conduit, tseem hu ua lub tes tsho nruj teeb galvanized steel conduit, yog ib hom conduit siv rau hluav taws xob tiv thaiv hluav taws xob. Los ntawm nws qhov tshwj xeeb nruj teeb kev sib txuas tshuab thiab lub cev zoo heev, nws muab kev tiv thaiv zoo rau cov xov hlau thiab cables.
