Dab tsi yog steel tsho insulated yeeb nkab?
Steel jacketed insulated yeeb nkab yog ib qho prefabricated, ncaj qha - faus kav dej tsim los ntawm Xingbang tshwj xeeb rau siab - kub thauj mus los (150℃txog 350℃). Nws nta ib qho "steel- nyob rau hauv -steel" cov qauv sib xyaw thiab kev ua haujlwm siab ntawm 2.5 MPa. Muaj nyob rau hauv ob qho tib si "sab hauv- zawv zawg" thiab "sab nraud- zawv zawg" kev teeb tsa, cov khoom txwv qhov ntsuas kub poob qis dua lossis sib npaug li 3℃ib mais thiab txo qhov kub poob ntau dua 70% piv rau cov kav dej ib txwm muaj. Cov txheej sab nrauv suav nrog kev tiv thaiv- tiv thaiv corrosion thiab noo noo{15}} qhov ntsuas cua. Nrog rau kev tsim lub neej ntawm 25-30 xyoo, nws yog qhov tsim nyog rau kev siv xws li hauv nroog hauv nroog cua sov, kev ua lag luam petrochemical, thiab cov chaw ua si hauv chaw ua haujlwm.
Nkag siab txog cov txheej txheem zawv zawg
Raws li yuav ua li cas thermal expansion displacement ntawm cov cab kuj yeeb nkab yog tswj, steel-jacketed insulated kav yog categorized ua ob yam qauv: sab hauv- zawv zawg thiab sab nraud- zawv zawg:
Sab hauv - zawv zawg hom
Cov yeeb nkab nqa tau swb nyob rau hauv cov txheej txheem rwb thaiv tsev, thaum cov khoom siv rwb thaiv tsev thiab sab nrauv nyob ruaj ruaj; hom no feem ntau siv cov khoom siv rwb thaiv tsev nruj. Qhov zoo muaj xws li tshem tawm cov kev txhawb nqa rings ntawm sab nrauv phab ntsa sab hauv, txo cov kev pheej hmoo corrosion. Qhov tsis zoo muaj xws li lub peev xwm rau kev rwb thaiv tsev eccentricity los yog crushing nyob rau hauv qhov hnyav ntawm cov cab kuj yeeb nkab, nrog rau cov kev cov nyom nyob rau hauv kev tswj cov hluav taws xob tawm sab nraud.
Sab nrauv - zawv zawg hom
Cov cab kuj thiab cov txheej txheem rwb thaiv tsev swb raws li ib chav tsev nyob rau sab nrauv; hom no feem ntau siv cov ntaub ntawv rwb thaiv tsev hloov tau yooj yim thiab sawv cev rau cov qauv tsim thoob ntiaj teb. Cov txiaj ntsig muaj xws li kev siv lub nplhaib txhawb nqa sab hauv los tiv thaiv kev rwb thaiv tsev eccentricity lossis crushing, superior noo noo venting, thiab simplified kev ntxhov siab; nws zoo daws teeb meem txog kev sib txhuam ntau ntxiv los ntawm radial expansion.
Kev pom zoo xaiv:Sab hauv - zawv zawg hom muaj cov qauv compact thiab tus nqi nruab nrab, ua rau nws haum rau cov qauv kev ua haujlwm. Sab nrauv - zawv zawg hom muab cov dej noo zoo tshaj - qhov ua haujlwm tau zoo thiab tau pom zoo rau cov haujlwm uas muaj cov dej hauv av siab lossis cov dej noo nruj heev - qhov yuav tsum tau ua kom muaj cua.
Nws cov txiaj ntsig tseem ceeb yog dab tsi?
Kub kub thiab siab tsis kam
Haum rau qhov kub ntawm 150℃-350℃thiab siab ntawm 2.5 MPa; burst siab ntau dua los yog sib npaug rau 3 npaug ntawm kev ua haujlwm siab.
Tsis tshua muaj kub poob
Thaum tshav kub kub poob yog txo los ntawm 70% piv rau cov kev daws teeb meem ib txwm muaj; Qhov kub poob qis dua los yog sib npaug li 3℃ib mais.
Ntev tiv thaiv -corrosion lifespan
Nta 3PE/FBE los tiv thaiv- txheej txheej; tsim los rau lub neej ua haujlwm ntawm 25-30 xyoo.
Cov dej ntws tawm thiab kev saib xyuas
Ua- hauv cov kav dej tshem tawm cov dej noo thiab ua ob npaug raws li cov kab hluav taws xob kuaj pom.
Qhov twg tuaj yeem steel jacketed insulated kav yuav siv tau?
1. Cov cua sov hauv nroog
Siab -kub qhov hluav taws xob lub cev sib txuas rau cov nroog, muab cov cua sov rau thaj chaw nyob thiab chaw lag luam thaum lub caij ntuj no.
2. Petrochemical kev lag luam
Chav sib txuas tes hauj lwm rau refineries thiab tshuaj nroj tsuag, siv rau txheej txheem cua sov, thauj khoom, thiab lwm yam.
3. Kev lag luam fais fab
Siab -kub cov kav xa hluav taws xob thiab cov khoom siv hluav taws xob pov tseg rau thermal fais fab nroj tsuag.
4. Industrial park centralized chav mov
Centralized steam mov systems rau ntau qhov chaw ua lag luam, muab chav rau kev tsim khoom rau cov neeg xauj tsev.
5. Cov cheeb tsam uas nyuaj struts
Direct-faus steel-jacketed piping muaj qhov zoo sib xws hauv cov cheeb tsam uas muaj cov dej hauv av siab uas qhov kev khawb trench tsis siv tau.
FAQ
Q: Qhov txawv ntawm steel -jacketed thiab yas-jacketed steel kav?
A: Yas- cov kav dej tsho siv cov HDPE sab nrauv thiab tsim nyog rau cov dej kub tsawg dua lossis sib npaug li 120℃; steel- cov kav dej siv lub tsho hlau siv cov hlau sab nrauv thiab tsim nyog rau chav dej ntawm 150℃-350 degree, muab qhov zoo tshaj qhov kub thiab txias, siab bearing, thiab txhua yam muaj zog.
Q: Xingbang qhov zoo yog dab tsi?
A: Raws li kev txhawb nqa rau ntau lub teb chaws tus qauv, Xingbang muaj peev xwm tsim tau txhua xyoo ntawm 1,000 km ntawm steel -jacketed chav rwb thaiv tsev kav thiab tuaj yeem tsim tau ntau qhov ntau thiab tsawg ntawm DN20 txog DN1200 hli.
Q: Cov qauv twg ua raws?
A: Kev ua raws li CJ / T 246-2018 thiab CJJ / T 104-2014.
