Carbon Steel Thaum tshav kub kub Exchanger

Cov pa roj carbon steel kub exchangers yog ntau hom kev lag luam petrochemical, hluav taws xob, thiab kev lag luam tshuaj. Thaum cov kua dej tsis zoo corrosive, thiab thaum ua haujlwm kub thiab siab poob hauv cov pa roj carbon steel lub peev xwm (lub plhaub tsim kub feem ntau yog -}20℃txog 400 degree, siab txog li 10 MPa lossis siab dua), carbon steel muab tus nqi zoo tshaj - rau kev ua haujlwm sib npaug.

Lub plhaub thiab lub raj ntim yog ua los ntawm Q345R, Q235B lossis zoo sib xws ntawm cov hlab ntsha steel. Tubesheets thiab baffles phim tib yam khoom siv tsev neeg. Yog hais tias lub plhaub -sab los yog raj- sab nruab nrab muaj cov khoom corrosive me me, ib qho kev tiv thaiv corrosion (feem ntau yog 1.5mm txog 3.0mm) tuaj yeem ntxiv thaum lub tshuab tsim. Rau kev siv sab nraum zoov uas xav tau kev tiv thaiv xeb, sab nrauv tuaj yeem pleev xim lossis kub -dip galvanized; Kev ntxuav sab hauv los yog passivation yog xaiv tau raws li qhov nruab nrab.

Cov pa roj carbon steel muaj cov thermal conductivity ntau dua li cov hlau tsis muaj steel. Rau tib lub luag haujlwm thermal, lub tshuab hluav taws xob carbon steel feem ntau xav tau qhov chaw hloov hluav taws xob tsawg dua. Txawm li cas los xij, carbon steel tsis haum rau chlorides, acids, alkalis, dej hiav txwv txias, los yog ntub dej hydrogen sulfide kev pab. Yog tias cov cuab yeej yuav tsum tau muab tso rau hauv qhov chaw siab - av noo thiab yuav nyob twj ywm rau lub sijhawm ntev, kev xeb sab hauv tuaj yeem tshwm sim. Hauv cov xwm txheej zoo li no, pom zoo kom siv nitrogen pam vov lossis ua pa tawm raws sijhawm.

Peb ua cov ntsuas cua sov siv HTRI / ASPEN thiab tsim rau GB, ASME, lossis TEMA cov qauv. Peb lub khw muaj peev xwm suav nrog carbon steel phaj dov, tsis siv neeg thiab phau ntawv vuam, thiab tsis yog -kev sim ua kom puas (RT/UT). Plhaub-sab thiab raj- sab kev ntsuas siab ua ntej xa khoom. ASME U Stamp, PED daim ntawv pov thawj, thiab cov ntawv pov thawj hauv zej zog muaj nyob rau thaum thov. Peb cov kev pabcuam npog tag nrho cov txheej txheem los ntawm kev tsim thermal, kev yuav khoom, mus rau kev taw qhia kev teeb tsa.
