Base yeeb nkab xaiv rau Finned Tubes
A cev finyog lub tshav kub-hloov cov khoom uas txav cov cua sov los ntawm cov kua dej kub mus rau cov kua dej txias los ntawm lub raj phab ntsa. Los ntawm kev ua kom thaj chaw sab nrauv, fins tsa cov cua sov tag nrho- hloov pauv thiab txo tag nrho cov raj yuav tsum tau; nyob rau hauv ntau lub installation finned tubes hloov rau los yog ntau dua liab qab raj ntawm ib feem ntawm tus nqi thiab qhov hnyav. Qhov kev ua tau zoo ntawm cov khoom tiav, txawm li cas los xij, nyob ntawm qhov ua ntejcev cev, uas nws cov khoom yuav tsum sib haum rau qhov kub, siab thiab corrosiveness ntawm cov dej kev pab cuam.

Dab tsi yog Steel Fin Tube siv rau?
Fin raj feem ntau yog siv rau hauv siab -kub thiab corrosive cua, nrog rau cov boiler economizers, tshav kub exchangers, convection seem ntawm txheej txheem cua sov thiab roj txias. Kev lag luam feem ntau yog kev lag luam hluav taws xob, kev lag luam tshuaj thiab petrochemical, kev ua zaub mov thiab tub yees, thiab kev lag luam roj thiab roj.
Kev Taw Qhia Xaiv
Xaiv lub hauv paus yeeb nkab qib raws li qhov kub thiab txias, lub plhaub -sab thiab raj- sab xov xwm, thiab lub siab tsim. Cov pa roj carbon steel puag yog kev lag luam rau kev huv, kev pabcuam nruab nrab; alloy steel puag xws li T11 los yog T22 yuav tsum tau rau siab kub; stainless thiab duplex bases lis corrosive kua; tooj liab thiab titanium hauv paus pab dej hiav txwv thiab tshwj xeeb cua sov- hloov lub luag haujlwm. Txheeb xyuas cov qauv yeeb nkab hauv qab, cov xov tooj cua sov traceability thiab fin- mus rau -tube daim ntawv cog lus txoj kev ua ntej xaj.
Cov lus nug nquag nug (FAQ)
Dab tsi yog cov khoom siv hauv qab tshaj plaws rau cov raj finned?
Carbon steel rau ASTM A179, A192, A106 Gr. B los yog API 5L Gr. B yog qhov kev xaiv pheej yig tshaj plaws rau cov txheej txheem boiler thiab cov khoom siv cua sov.
Cov yeeb nkab steel hlau puas tuaj yeem siv los ua finned tube puag?
