Insulated steel kav yog composite yeeb nkab tshuab uas sib txuas ua ke muaj peev xwm nrog cov thev naus laus zis siv tau zoo. Lawv tau siv dav hauv cov roj av, tshuaj, koog tsev kawm ntawv cua sov, tub yees, thiab kev lag luam rwb thaiv tsev. Lawv cov qauv tseem ceeb nyob hauv lawv cov qauv kev tsim qauv tshwj xeeb, uas txo cov cua sov thaum ua kom haum rau kev ua kom haum thiab muaj zog tiv taus.
I. Cov txheej txheem theem yooj yim ntawm cov kav hlau insulated steel kav
Insulated steel kav kav tsis tau tsim los ntawm ib qho khoom tab sis theej muaj ntawm ib qho kev ua haujlwm me me steel qauv: ib txheej txheej txheem steel, thiab rwb thaiv tsev txheej, thiab lub plhaub txheej tiv thaiv. Qee cov qauv tsim kuj tseem teeb tsa cov kev ua haujlwm sib txuas ua haujlwm xws li xau cov kab.
1. Ua Haujlwm Steel Yeeb Nkab (Sab Laj Kab)
Ua haujlwm cov kav hlau ua haujlwm yog cov cab ncaj qha ntawm cov khoom siv hluav taws xob (xws li dej kub, chav, lossis roj). Lawv feem ntau yog ua los ntawm seamless steel yeeb nkab, muab kauv welded yeeb nkab, lossis ncaj seam welded yeeb nkab. Cov khoom tau raug xaiv raws cov yam ntxwv ntawm cov khoom nruab nrab, xws li cov hlau steel, stainless hlau, lossis alloy steel. Sab hauv phab ntsa yuav tsum tau ntsib corrosion thiab siab- cov kev xav tau, thaum lub phab ntsa sab nraud yuav tsum tau sib khi kom nruj rau cov txheej rwb thaiv tsev.
2. Rwb thaiv txheej txheej (nruab nrab rwb thaiv tsev txheej)
Lub rwb thaiv tsev txheej yog cov txheej txheem tseem ceeb ntawm cov yeeb nkab insulated steel yeeb nkab, nws txoj haujlwm loj yog los thaiv kev kub hloov. Cov ntaub ntawv Rwb thaiv tsev muaj xws li:
Polyurethane ua npuas ncauj (PUF): Tsawg thermal conductivity (kwv yees li 0.024 w / min {{1} {} Cov ntsiab lus ntawm tes, thiab muaj zog compressive cell. Tam sim no yog cov khoom siv hluav taws xob tseem ceeb tshaj plaws thiab yog foamed ntawm - thaj tsam lossis prefabricated hauv cov Hoobkas.
Lub pob zeb tsiaj / iav ntaub plaub: Tsim nyog rau high {{0 eg, saum 500 degree), tab sis muaj qhov nteg ntom thiab muaj kev hygroscopicity.
Airgel Composite Txheej: Ib qho tshiab Ultra - lub teeb nanomaterial nrog tsis tshua muaj cua sov condal condality (<0.018 W/m·K), but it is more expensive and is primarily used in specialized, high-end projects.
Lub thickness ntawm rwb thaiv tsev txheej yog suav raws li qhov nruab nrab kub, huab cua kub sib txawv, thiab kev xav txog kev lag luam, feem ntau yog kwv yees li 30 txog 150 hli.
3. Tiv Thaiv Plhaub (Txheej Txheem Txheej Txheem)
Lub plhaub pob zeb tiv thaiv cov rwb thaiv tsev txheej los ntawm kev ua tshuab puas tsuaj, UV hluav taws xob, thiab cov av corrosion. Cov Khoom Siv Uas Muaj:
Siab -} ceev polyethylene (HDPOSION): Tsim los ntawm kev teeb tsa hauv av, tsim los ntawm tshav kub- yaj vuam.
Galvanized steel / Aluminium: Siv rau overhead pipelines lossis siab {{}- corrosion txheej kom txuas ntxiv rau nws lub neej kev pabcuam.
Fiberglass txhawb nqa yas (frp): sib txuas ntawm lub teeb yuag, ua rau nws haum rau cov tshuaj lom neeg.
Ii. Pab Pawg Cov Qauv thiab Kev Ntsuas Txuas Ntxiv
Qee qhov siab -}}} edulated steel yeeb nkab tuaj yeem txuas ntxiv cov qauv hauv qab no:
Take tswb cov xov hluav taws xob: Embedded rau hauv cov txheej txheem txheej, nws sai nrhiav qhov txhaum hluav taws xob hloov pauv thaum muaj cov yeeb nkab ua haujlwm, txhim kho kev nyab xeeb.
Zawv zawg bracket / Txhawb Nplhaib: Siv rau ntev- Cov kav dej ntws los ntawm thermal exporansion kev ntxhov siab.
Lub tshuab nqus tsev (lub tshuab ua haujlwm tsawg thiab tshwj xeeb ntxiv): Qhov no ntxiv txo cov cua sov los ntawm kev nqus cua sov, tab sis tus nqi ntsuas yog qhov siab heev.
III. Cov Txheej Txheem Txheej Txheem Ntawm Insulated Hlau Kav
High - Kev Ua Haujlwm Zoo Tshaj Plaws Synes Synes Zoo Tshaj Tias Ntawm Cov Kav Dej Hlau Loj
Lub neej ntev: lub ntsej muag sab nraud yog corrosion - tiv taus thiab tiv taus geological lub sijhawm, nrog rau cov qauv tsim ua ntej 30 txog 50 xyoo.
Kev Tsim Kho Yooj Yim: Pre-{0} {}} Cov Khoom Siv Hluav Taws Xob Interulated enterface, Lub sijhawm muaj kev tsim kho tshwj xeeb.
Kev tiv thaiv ib puag ncig thiab txuag hluav taws xob: txo cov hluav taws xob khib nyiab, ua kom cov khoom lag luam ntsuab "ntawm cov phiaj xwm" Ob chav ".
